86364793 ÷ 100 
Our goal is to divide 86364793 by 100.

On to step 1:
8 divided by 100 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 100

Going ahead to step 2:
86 divided by 100 is 0 with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Fetch the next digit (3) from the dividend, attach it to 86 and continue: 863 / 100

Moving on to step 3:
863 divided by 100 is 8 with a remainder of 63.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 63 after subtracting 800 from 863.
Grab the next digit (6) from the dividend, add it to 63, then carry on: 636 / 100

Let's proceed to step 4:
The number 100 fits into 636 6 times, leaving a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 86.0
Subtract 600 from 636 to get 36.
Take the next digit (4) from the dividend and append it to 36, then repeat: 364 / 100

On to step 5:
When dividing 364 by 100, we get 3 with a remainder of 64.
The number 3 becomes the next digit in our result. 
Result so far: 863.0
Subtract 300 from 364 to get 64.
Take the next digit (7) from the dividend and append it to 64, then repeat: 647 / 100

Advancing to step 6:
When dividing 647 by 100, we get 6 with a remainder of 47.
Put 6 as the next digit of the answer. 
Result so far: 8636.0
If we subtract 600 from 647, we get 47.
Grab the next digit (9) from the dividend, add it to 47, then carry on: 479 / 100

On to step 7:
The number 100 fits into 479 4 times, leaving a remainder of 79.
Put 4 as the next digit of the answer. 
Result so far: 86364.0
Deduct 400 from 479 and we're left with 79.
Include the next digit (3) from the dividend after 79, then repeat: 793 / 100

Advancing to step 8:
100 goes into 793 7 times with a remainder of 93.
The number 7 becomes the next digit in our result. 
Result so far: 863647.0
Subtract 700 from 793 to get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Going ahead to step 9:
The number 100 fits into 930 9 times, leaving a remainder of 30.
Record the quotient 9 as the next digit in the result. 
Result so far: 863647.9
If we take 900 away from 930, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
The number 100 fits into 300 3 times, leaving a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 863647.93
If we take 300 away from 300, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
If we divide 0 by 100, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 863647.93
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 12:
100 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 863647.93
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 863647.93, with a leftover of 0.0.
