We look at the division of 863878 by 63 
We want to figure out the number of times 863878 can be divided by 63.

Moving on to step 1:
63 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 63

Moving on to step 2:
86 divided by 63 is 1 with 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 (3) from the dividend, add it to 23, then carry on: 233 / 63

Step 3:
The number 63 fits into 233 3 times, leaving a remainder of 44.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 44 after subtracting 189 from 233.
Grab the next digit (8) from the dividend, add it to 44, then carry on: 448 / 63

Moving on to step 4:
448 divided by 63 is 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 137.0
Subtract 441 from 448 to get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 63

Moving on to step 5:
63 can be fit into 77 1 times, resulting in a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1371.0
Subtract 63 from 77 to get 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 63

Step 6:
148 divided by 63 is 2 with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 13712.0
If we take 126 away from 148, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
If we divide 220 by 63, we get 3 and a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 13712.3
If we take 189 away from 220, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 8:
63 can be fit into 310 4 times, resulting in a remainder of 58.
Put 4 as the next digit of the answer. 
Result so far: 13712.34
Deduct 252 from 310 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 9:
580 divided by 63 is 9 with a remainder of 13.
The next digit of our result is 9. 
Result so far: 13712.349
The remainder is 13 after subtracting 567 from 580.
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 10:
63 can be fit into 130 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 13712.3492
If we subtract 126 from 130, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
The number 63 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 13712.3492
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
400 divided by 63 is 6 with a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 13712.349206
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 13:
When dividing 220 by 63, we get 3 with a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 13712.3492063
If we take 189 away from 220, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 14:
63 can be fit into 310 4 times, resulting in a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 13712.34920634
The remainder is 58 after subtracting 252 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Our division results in 13712.34920634 with a remaining 5.8e-08.
