Let's divide 86869 by 63
We want to divide 86869 by 63.

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
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 63

On to step 2:
If we divide 86 by 63, we get 1 and a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 63 from 86, we get 23.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 63

Advancing to step 3:
63 can be fit into 238 3 times, resulting in a remainder of 49.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtract 189 from 238 to get 49.
Append the next digit (6) from the dividend to 49 and continue with: 496 / 63

Step 4:
The number 63 fits into 496 7 times, leaving a remainder of 55.
Use 7 as the next digit of our solution. 
Result so far: 137.0
The remainder is 55 after subtracting 441 from 496.
Append the next digit (9) from the dividend to 55 and continue with: 559 / 63

Going ahead to step 5:
559 divided by 63 is 8 with a remainder of 55.
Write down 8 as next digit of the result. 
Result so far: 1378.0
Subtract 504 from 559 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 6:
63 can be fit into 550 8 times, resulting in a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 1378.8
Deduct 504 from 550 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 7:
The number 63 fits into 460 7 times, leaving a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 1378.87
Subtracting 441 from 460 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 8:
63 goes into 190 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 1378.873
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 9:
10 divided by 63 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 1378.873
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
63 goes into 100 1 times with a remainder of 37.
The next digit of our result is 1. 
Result so far: 1378.87301
Deduct 63 from 100 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 11:
When dividing 370 by 63, we get 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 1378.873015
Subtracting 315 from 370 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 12:
If we divide 550 by 63, we get 8 and a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 1378.8730158
Subtract 504 from 550 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 13:
The number 63 fits into 460 7 times, leaving a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 1378.87301587
If we take 441 away from 460, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 1378.87301587, with a leftover of 1.9e-08.
