We look at the division of 86986220 by 63 
Our goal is to divide 86986220 by 63.

On to step 1:
63 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 63

On to step 2:
When dividing 86 by 63, we get 1 with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 23 after subtracting 63 from 86.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 63

Advancing to step 3:
When dividing 239 by 63, we get 3 with a remainder of 50.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 189 from 239 to get 50.
Grab the next digit (8) from the dividend, add it to 50, then carry on: 508 / 63

On to step 4:
508 divided by 63 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 138.0
If we take 504 away from 508, we end up with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 63

Moving on to step 5:
63 can be fit into 46 0 times, resulting in a remainder of 46.
Write down 0 as next digit of the result. 
Result so far: 1380.0
If we subtract 0 from 46, we get 46.
Fetch the next digit (2) from the dividend, attach it to 46 and continue: 462 / 63

Going ahead to step 6:
If we divide 462 by 63, we get 7 and a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 13807.0
The remainder is 21 after subtracting 441 from 462.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 63

Moving on to step 7:
If we divide 212 by 63, we get 3 and a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 138073.0
If we subtract 189 from 212, we get 23.
Bring next digit (0) of the dividend behind the 23 and repeat the process: 230 / 63

Let's proceed to step 8:
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: 1380733.0
Subtracting 189 from 230 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 9:
63 can be fit into 410 6 times, resulting in a remainder of 32.
The next digit of our result is 6. 
Result so far: 1380733.6
If we take 378 away from 410, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
When dividing 320 by 63, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 1380733.65
Deduct 315 from 320 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 11:
63 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 1380733.65
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 12:
When dividing 500 by 63, we get 7 with a remainder of 59.
Write down 7 as next digit of the result. 
Result so far: 1380733.6507
If we subtract 441 from 500, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 13:
If we divide 590 by 63, we get 9 and a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 1380733.65079
If we take 567 away from 590, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 14:
When dividing 230 by 63, we get 3 with a remainder of 41.
Put 3 as the next digit of the answer. 
Result so far: 1380733.650793
If we take 189 away from 230, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 15:
The number 63 fits into 410 6 times, leaving a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 1380733.6507936
If we subtract 378 from 410, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 16:
63 goes into 320 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 1380733.65079365
Subtracting 315 from 320 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 1380733.65079365 with a remainder of 5e-09.
