We look at the division of 815699 by 63 
We're looking to find how many times 63 goes into 815699.

Going ahead to step 1:
8 divided by 63 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 63

Step 2:
If we divide 81 by 63, we get 1 and a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 63 from 81 to get 18.
Fetch the next digit (5) from the dividend, attach it to 18 and continue: 185 / 63

Advancing to step 3:
The number 63 fits into 185 2 times, leaving a remainder of 59.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 126 from 185 and we're left with 59.
Include the next digit (6) from the dividend after 59, then repeat: 596 / 63

Step 4:
The number 63 fits into 596 9 times, leaving a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 129.0
Subtracting 567 from 596 leaves us with 29.
Append the next digit (9) from the dividend to 29 and continue with: 299 / 63

Moving on to step 5:
299 divided by 63 is 4 with a remainder of 47.
Write down 4 as next digit of the result. 
Result so far: 1294.0
The remainder is 47 after subtracting 252 from 299.
Include the next digit (9) from the dividend after 47, then repeat: 479 / 63

Step 6:
The number 63 fits into 479 7 times, leaving a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 12947.0
Subtracting 441 from 479 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 7:
If we divide 380 by 63, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 12947.6
If we take 378 away from 380, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
When dividing 20 by 63, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 12947.6
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
When dividing 200 by 63, we get 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 12947.603
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 10:
When dividing 110 by 63, we get 1 with a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 12947.6031
Subtracting 63 from 110 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 11:
63 goes into 470 7 times with a remainder of 29.
The next digit of our result is 7. 
Result so far: 12947.60317
If we subtract 441 from 470, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 12:
63 can be fit into 290 4 times, resulting in a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 12947.603174
If we take 252 away from 290, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 13:
63 goes into 380 6 times with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 12947.6031746
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 14:
63 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 12947.6031746
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 12947.6031746 with a remaining 2e-08.
