86693099 ÷ 100 
Our goal is to divide 86693099 by 100.

On to step 1:
8 divided by 100 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
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 / 100

On to step 2:
The number 100 fits into 86 0 times, leaving a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Append the next digit (6) from the dividend to 86 and continue with: 866 / 100

Let's proceed to step 3:
100 can be fit into 866 8 times, resulting in a remainder of 66.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 800 from 866 to get 66.
Fetch the next digit (9) from the dividend, attach it to 66 and continue: 669 / 100

Advancing to step 4:
100 goes into 669 6 times with a remainder of 69.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
If we take 600 away from 669, we end up with 69.
Take the next digit (3) from the dividend and append it to 69, then repeat: 693 / 100

On to step 5:
When dividing 693 by 100, we get 6 with a remainder of 93.
Write down 6 as next digit of the result. 
Result so far: 866.0
Subtract 600 from 693 to get 93.
Bring next digit (0) of the dividend behind the 93 and repeat the process: 930 / 100

Moving on to step 6:
If we divide 930 by 100, we get 9 and a remainder of 30.
The next digit of our result is 9. 
Result so far: 8669.0
If we subtract 900 from 930, we get 30.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 100

Moving on to step 7:
When dividing 309 by 100, we get 3 with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 86693.0
Deduct 300 from 309 and we're left with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 100

Moving on to step 8:
99 divided by 100 is 0 with a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 866930.0
Deduct 0 from 99 and we're left with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Moving on to step 9:
When dividing 990 by 100, we get 9 with a remainder of 90.
The next digit of our result is 9. 
Result so far: 866930.9
The remainder is 90 after subtracting 900 from 990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 10:
The number 100 fits into 900 9 times, leaving a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 866930.99
If we take 900 away from 900, 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.

Our division results in 866930.99 with a remaining 0.0.
