722811 divided by 51 
We want to figure out the number of times 722811 can be divided by 51.

Going ahead to step 1:
51 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 51

Going ahead to step 2:
51 goes into 72 1 times with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 51 away from 72, we end up with 21.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 51

Step 3:
51 goes into 212 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 204 from 212 and we're left with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 51

Advancing to step 4:
51 can be fit into 88 1 times, resulting in a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 141.0
If we take 51 away from 88, we end up with 37.
Grab the next digit (1) from the dividend, add it to 37, then carry on: 371 / 51

Moving on to step 5:
51 goes into 371 7 times with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 1417.0
If we take 357 away from 371, we end up with 14.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 51

Let's proceed to step 6:
141 divided by 51 is 2 with a remainder of 39.
Record the quotient 2 as the next digit in the result. 
Result so far: 14172.0
If we subtract 102 from 141, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 7:
The number 51 fits into 390 7 times, leaving a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 14172.7
The remainder is 33 after subtracting 357 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 8:
51 can be fit into 330 6 times, resulting in a remainder of 24.
The next digit of our result is 6. 
Result so far: 14172.76
If we take 306 away from 330, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
51 goes into 240 4 times with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 14172.764
The remainder is 36 after subtracting 204 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 10:
51 can be fit into 360 7 times, resulting in a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 14172.7647
If we take 357 away from 360, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 11:
When dividing 30 by 51, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 14172.7647
Subtracting 0 from 30 leaves us 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.

Step 12:
When dividing 300 by 51, we get 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 14172.764705
If we take 255 away from 300, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 13:
The number 51 fits into 450 8 times, leaving a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 14172.7647058
If we subtract 408 from 450, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 14:
When dividing 420 by 51, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 14172.76470588
If we take 408 away from 420, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 14172.76470588 and a remainder of 1.2e-08.
