We look at the division of 860631 by 63 
Let's see how many times 63 fits into 860631.

Advancing to step 1:
8 divided by 63 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 63

Step 2:
When dividing 86 by 63, we get 1 with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 63 away from 86, we end up with 23.
Include the next digit (0) from the dividend after 23, then repeat: 230 / 63

Advancing to step 3:
If we divide 230 by 63, we get 3 and a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 189 from 230 to get 41.
Grab the next digit (6) from the dividend, add it to 41, then carry on: 416 / 63

Advancing to step 4:
If we divide 416 by 63, we get 6 and a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 136.0
The remainder is 38 after subtracting 378 from 416.
Take the next digit (3) from the dividend and append it to 38, then repeat: 383 / 63

Advancing to step 5:
The number 63 fits into 383 6 times, leaving a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 1366.0
If we take 378 away from 383, we end up with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 63

On to step 6:
63 can be fit into 51 0 times, resulting in a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 13660.0
The remainder is 51 after subtracting 0 from 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 7:
The number 63 fits into 510 8 times, leaving a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 13660.8
Subtracting 504 from 510 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
63 can be fit into 60 0 times, resulting in a remainder of 60.
The next digit of our result is 0. 
Result so far: 13660.8
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
When dividing 600 by 63, we get 9 with a remainder of 33.
The next digit of our result is 9. 
Result so far: 13660.809
If we take 567 away from 600, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 10:
63 can be fit into 330 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 13660.8095
If we take 315 away from 330, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
150 divided by 63 is 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 13660.80952
If we subtract 126 from 150, we get 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 12:
When dividing 240 by 63, we get 3 with a remainder of 51.
The number 3 becomes the next digit in our result. 
Result so far: 13660.809523
The remainder is 51 after subtracting 189 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 13:
If we divide 510 by 63, we get 8 and a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 13660.8095238
Subtracting 504 from 510 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
63 goes into 60 0 times with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 13660.8095238
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 13660.8095238 with a remainder of 6e-08.
