We're dividing 15210729 by 772 
We want to divide 15210729 by 772.

Advancing to step 1:
1 divided by 772 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 772

On to step 2:
772 can be fit into 15 0 times, resulting in a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Append the next digit (2) from the dividend to 15 and continue with: 152 / 772

Step 3:
When dividing 152 by 772, we get 0 with a remainder of 152.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 152 after subtracting 0 from 152.
Take the next digit (1) from the dividend and append it to 152, then repeat: 1521 / 772

Let's proceed to step 4:
The number 772 fits into 1521 1 times, leaving a remainder of 749.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 772 from 1521 and we're left with 749.
Fetch the next digit (0) from the dividend, attach it to 749 and continue: 7490 / 772

On to step 5:
772 goes into 7490 9 times with a remainder of 542.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Deduct 6948 from 7490 and we're left with 542.
Include the next digit (7) from the dividend after 542, then repeat: 5427 / 772

Advancing to step 6:
When dividing 5427 by 772, we get 7 with a remainder of 23.
The next digit of our result is 7. 
Result so far: 197.0
If we subtract 5404 from 5427, we get 23.
Append the next digit (2) from the dividend to 23 and continue with: 232 / 772

Step 7:
232 divided by 772 is 0 with a remainder of 232.
Record the quotient 0 as the next digit in the result. 
Result so far: 1970.0
Deduct 0 from 232 and we're left with 232.
Grab the next digit (9) from the dividend, add it to 232, then carry on: 2329 / 772

Going ahead to step 8:
When dividing 2329 by 772, we get 3 with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 19703.0
Subtract 2316 from 2329 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 9:
The number 772 fits into 130 0 times, leaving a remainder of 130.
Write down 0 as next digit of the result. 
Result so far: 19703.0
The remainder is 130 after subtracting 0 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 10:
When dividing 1300 by 772, we get 1 with a remainder of 528.
The number 1 becomes the next digit in our result. 
Result so far: 19703.01
If we take 772 away from 1300, we end up with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Step 11:
The number 772 fits into 5280 6 times, leaving a remainder of 648.
Put 6 as the next digit of the answer. 
Result so far: 19703.016
Subtract 4632 from 5280 to get 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Advancing to step 12:
772 goes into 6480 8 times with a remainder of 304.
Use 8 as the next digit of our solution. 
Result so far: 19703.0168
If we subtract 6176 from 6480, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 13:
3040 divided by 772 is 3 with a remainder of 724.
Record the quotient 3 as the next digit in the result. 
Result so far: 19703.01683
If we subtract 2316 from 3040, we get 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Advancing to step 14:
7240 divided by 772 is 9 with a remainder of 292.
The number 9 becomes the next digit in our result. 
Result so far: 19703.016839
If we take 6948 away from 7240, we end up with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Step 15:
When dividing 2920 by 772, we get 3 with a remainder of 604.
The number 3 becomes the next digit in our result. 
Result so far: 19703.0168393
The remainder is 604 after subtracting 2316 from 2920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Advancing to step 16:
When dividing 6040 by 772, we get 7 with a remainder of 636.
The number 7 becomes the next digit in our result. 
Result so far: 19703.01683937
Subtracting 5404 from 6040 leaves us with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

The quotient of the division is 19703.01683937, and the remainder is 6.36e-07.
