75599129 ÷ 636 
Our goal is to divide 75599129 by 636.

Going ahead to step 1:
If we divide 7 by 636, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 636

On to step 2:
If we divide 75 by 636, we get 0 and a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Bring next digit (5) of the dividend behind the 75 and repeat the process: 755 / 636

Let's proceed to step 3:
If we divide 755 by 636, we get 1 and a remainder of 119.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 119 after subtracting 636 from 755.
Include the next digit (9) from the dividend after 119, then repeat: 1199 / 636

Step 4:
If we divide 1199 by 636, we get 1 and a remainder of 563.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 636 from 1199 leaves us with 563.
Append the next digit (9) from the dividend to 563 and continue with: 5639 / 636

Step 5:
If we divide 5639 by 636, we get 8 and a remainder of 551.
Put 8 as the next digit of the answer. 
Result so far: 118.0
Subtract 5088 from 5639 to get 551.
Fetch the next digit (1) from the dividend, attach it to 551 and continue: 5511 / 636

Moving on to step 6:
636 goes into 5511 8 times with a remainder of 423.
Write down 8 as next digit of the result. 
Result so far: 1188.0
Subtract 5088 from 5511 to get 423.
Include the next digit (2) from the dividend after 423, then repeat: 4232 / 636

Let's proceed to step 7:
When dividing 4232 by 636, we get 6 with a remainder of 416.
The next digit of our result is 6. 
Result so far: 11886.0
If we take 3816 away from 4232, we end up with 416.
Grab the next digit (9) from the dividend, add it to 416, then carry on: 4169 / 636

On to step 8:
The number 636 fits into 4169 6 times, leaving a remainder of 353.
Put 6 as the next digit of the answer. 
Result so far: 118866.0
Deduct 3816 from 4169 and we're left with 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

On to step 9:
636 goes into 3530 5 times with a remainder of 350.
Record the quotient 5 as the next digit in the result. 
Result so far: 118866.5
If we take 3180 away from 3530, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 10:
When dividing 3500 by 636, we get 5 with a remainder of 320.
Use 5 as the next digit of our solution. 
Result so far: 118866.55
Deduct 3180 from 3500 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The final outcome is 118866.55, with a leftover of 0.32.
