We look at the division of 51085407 by 702 
We want to figure out the number of times 51085407 can be divided by 702.

Moving on to step 1:
702 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 702

Going ahead to step 2:
When dividing 51 by 702, we get 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Include the next digit (0) from the dividend after 51, then repeat: 510 / 702

Moving on to step 3:
The number 702 fits into 510 0 times, leaving a remainder of 510.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 510 and we're left with 510.
Grab the next digit (8) from the dividend, add it to 510, then carry on: 5108 / 702

Let's proceed to step 4:
702 goes into 5108 7 times with a remainder of 194.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 194 after subtracting 4914 from 5108.
Bring next digit (5) of the dividend behind the 194 and repeat the process: 1945 / 702

Going ahead to step 5:
When dividing 1945 by 702, we get 2 with a remainder of 541.
The next digit of our result is 2. 
Result so far: 72.0
Subtracting 1404 from 1945 leaves us with 541.
Append the next digit (4) from the dividend to 541 and continue with: 5414 / 702

Let's proceed to step 6:
If we divide 5414 by 702, we get 7 and a remainder of 500.
Put 7 as the next digit of the answer. 
Result so far: 727.0
The remainder is 500 after subtracting 4914 from 5414.
Bring next digit (0) of the dividend behind the 500 and repeat the process: 5000 / 702

Step 7:
If we divide 5000 by 702, we get 7 and a remainder of 86.
Record the quotient 7 as the next digit in the result. 
Result so far: 7277.0
If we take 4914 away from 5000, we end up with 86.
Append the next digit (7) from the dividend to 86 and continue with: 867 / 702

Going ahead to step 8:
867 divided by 702 is 1 with a remainder of 165.
The next digit of our result is 1. 
Result so far: 72771.0
Subtract 702 from 867 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 9:
702 goes into 1650 2 times with a remainder of 246.
Write down 2 as next digit of the result. 
Result so far: 72771.2
If we subtract 1404 from 1650, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Going ahead to step 10:
If we divide 2460 by 702, we get 3 and a remainder of 354.
The number 3 becomes the next digit in our result. 
Result so far: 72771.23
Deduct 2106 from 2460 and we're left with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Going ahead to step 11:
When dividing 3540 by 702, we get 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 72771.235
Deduct 3510 from 3540 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 12:
The number 702 fits into 300 0 times, leaving a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 72771.235
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 13:
When dividing 3000 by 702, we get 4 with a remainder of 192.
Record the quotient 4 as the next digit in the result. 
Result so far: 72771.23504
If we subtract 2808 from 3000, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 14:
If we divide 1920 by 702, we get 2 and a remainder of 516.
Use 2 as the next digit of our solution. 
Result so far: 72771.235042
If we take 1404 away from 1920, we end up with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Going ahead to step 15:
702 can be fit into 5160 7 times, resulting in a remainder of 246.
Put 7 as the next digit of the answer. 
Result so far: 72771.2350427
If we subtract 4914 from 5160, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Going ahead to step 16:
702 can be fit into 2460 3 times, resulting in a remainder of 354.
Use 3 as the next digit of our solution. 
Result so far: 72771.23504273
If we take 2106 away from 2460, we end up with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

In conclusion, the division gives 72771.23504273 with a balance of 3.54e-07.
