We look at the division of 861744 by 63 
We're looking to find how many times 63 goes into 861744.

Going ahead to step 1:
63 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 63

On to step 2:
The number 63 fits into 86 1 times, leaving a remainder of 23.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 23 after subtracting 63 from 86.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 63

Going ahead to step 3:
When dividing 231 by 63, we get 3 with a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 189 from 231 leaves us with 42.
Fetch the next digit (7) from the dividend, attach it to 42 and continue: 427 / 63

Step 4:
The number 63 fits into 427 6 times, leaving a remainder of 49.
The next digit of our result is 6. 
Result so far: 136.0
Subtract 378 from 427 to get 49.
Grab the next digit (4) from the dividend, add it to 49, then carry on: 494 / 63

On to step 5:
63 can be fit into 494 7 times, resulting in a remainder of 53.
The next digit of our result is 7. 
Result so far: 1367.0
If we take 441 away from 494, we end up with 53.
Bring next digit (4) of the dividend behind the 53 and repeat the process: 534 / 63

On to step 6:
63 goes into 534 8 times with a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 13678.0
Subtract 504 from 534 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 7:
The number 63 fits into 300 4 times, leaving a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 13678.4
If we subtract 252 from 300, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 8:
If we divide 480 by 63, we get 7 and a remainder of 39.
Write down 7 as next digit of the result. 
Result so far: 13678.47
Deduct 441 from 480 and we're left with 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 9:
63 goes into 390 6 times with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 13678.476
The remainder is 12 after subtracting 378 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
The number 63 fits into 120 1 times, leaving a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 13678.4761
If we take 63 away from 120, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 11:
63 can be fit into 570 9 times, resulting in a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 13678.47619
The remainder is 3 after subtracting 567 from 570.
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 12:
63 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 13678.47619
If we subtract 0 from 30, we get 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 13:
If we divide 300 by 63, we get 4 and a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 13678.4761904
If we subtract 252 from 300, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 14:
63 goes into 480 7 times with a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 13678.47619047
Subtracting 441 from 480 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

After the division, we end up with 13678.47619047 and a remainder of 3.9e-08.
