We look at the division of 63197791 by 86 
Our goal is to divide 63197791 by 86.

Let's proceed to step 1:
If we divide 6 by 86, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 86

Moving on to step 2:
63 divided by 86 is 0 with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Append the next digit (1) from the dividend to 63 and continue with: 631 / 86

Let's proceed to step 3:
86 goes into 631 7 times with a remainder of 29.
The next digit of our result is 7. 
Result so far: 7.0
If we take 602 away from 631, we end up with 29.
Include the next digit (9) from the dividend after 29, then repeat: 299 / 86

Step 4:
If we divide 299 by 86, we get 3 and a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 73.0
If we subtract 258 from 299, we get 41.
Fetch the next digit (7) from the dividend, attach it to 41 and continue: 417 / 86

On to step 5:
417 divided by 86 is 4 with a remainder of 73.
The number 4 becomes the next digit in our result. 
Result so far: 734.0
Subtract 344 from 417 to get 73.
Take the next digit (7) from the dividend and append it to 73, then repeat: 737 / 86

On to step 6:
When dividing 737 by 86, we get 8 with a remainder of 49.
Write down 8 as next digit of the result. 
Result so far: 7348.0
Subtracting 688 from 737 leaves us with 49.
Fetch the next digit (9) from the dividend, attach it to 49 and continue: 499 / 86

On to step 7:
499 divided by 86 is 5 with a remainder of 69.
The number 5 becomes the next digit in our result. 
Result so far: 73485.0
Deduct 430 from 499 and we're left with 69.
Grab the next digit (1) from the dividend, add it to 69, then carry on: 691 / 86

Moving on to step 8:
If we divide 691 by 86, we get 8 and a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 734858.0
Subtracting 688 from 691 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
If we divide 30 by 86, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 734858.0
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 10:
When dividing 300 by 86, we get 3 with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 734858.03
The remainder is 42 after subtracting 258 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 11:
When dividing 420 by 86, we get 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 734858.034
The remainder is 76 after subtracting 344 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 12:
86 can be fit into 760 8 times, resulting in a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 734858.0348
The remainder is 72 after subtracting 688 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 13:
If we divide 720 by 86, we get 8 and a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 734858.03488
Deduct 688 from 720 and we're left 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.

The final outcome is 734858.03488, with a leftover of 3.2e-05.
