We're dividing 781153 by 51 
We want to divide 781153 by 51.

On to step 1:
When dividing 7 by 51, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 51

Let's proceed to step 2:
If we divide 78 by 51, we get 1 and a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 51 away from 78, we end up with 27.
Bring next digit (1) of the dividend behind the 27 and repeat the process: 271 / 51

On to step 3:
The number 51 fits into 271 5 times, leaving a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 255 from 271 leaves us with 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 51

Moving on to step 4:
51 goes into 161 3 times with a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 153.0
If we take 153 away from 161, we end up with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 51

Advancing to step 5:
51 can be fit into 85 1 times, resulting in a remainder of 34.
The next digit of our result is 1. 
Result so far: 1531.0
The remainder is 34 after subtracting 51 from 85.
Grab the next digit (3) from the dividend, add it to 34, then carry on: 343 / 51

Moving on to step 6:
If we divide 343 by 51, we get 6 and a remainder of 37.
Write down 6 as next digit of the result. 
Result so far: 15316.0
If we take 306 away from 343, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 7:
370 divided by 51 is 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 15316.7
If we take 357 away from 370, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 8:
The number 51 fits into 130 2 times, leaving a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 15316.72
Subtract 102 from 130 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
280 divided by 51 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 15316.725
Subtracting 255 from 280 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 10:
51 can be fit into 250 4 times, resulting in a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 15316.7254
Subtract 204 from 250 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 11:
If we divide 460 by 51, we get 9 and a remainder of 1.
The next digit of our result is 9. 
Result so far: 15316.72549
Subtract 459 from 460 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 12:
10 divided by 51 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 15316.72549
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
When dividing 100 by 51, we get 1 with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 15316.7254901
If we subtract 51 from 100, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 14:
51 goes into 490 9 times with a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 15316.72549019
The remainder is 31 after subtracting 459 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final result is 15316.72549019 with a remainder of 3.1e-08.
