78188180 ÷ 636 
We want to divide 78188180 by 636.

On to step 1:
When dividing 7 by 636, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 636

Going ahead to step 2:
78 divided by 636 is 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Take the next digit (1) from the dividend and append it to 78, then repeat: 781 / 636

Going ahead to step 3:
636 goes into 781 1 times with a remainder of 145.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 636 from 781 to get 145.
Include the next digit (8) from the dividend after 145, then repeat: 1458 / 636

Step 4:
If we divide 1458 by 636, we get 2 and a remainder of 186.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 1272 from 1458 leaves us with 186.
Append the next digit (8) from the dividend to 186 and continue with: 1868 / 636

Going ahead to step 5:
636 can be fit into 1868 2 times, resulting in a remainder of 596.
Put 2 as the next digit of the answer. 
Result so far: 122.0
If we take 1272 away from 1868, we end up with 596.
Fetch the next digit (1) from the dividend, attach it to 596 and continue: 5961 / 636

Moving on to step 6:
5961 divided by 636 is 9 with a remainder of 237.
Use 9 as the next digit of our solution. 
Result so far: 1229.0
Subtracting 5724 from 5961 leaves us with 237.
Grab the next digit (8) from the dividend, add it to 237, then carry on: 2378 / 636

Moving on to step 7:
636 goes into 2378 3 times with a remainder of 470.
Put 3 as the next digit of the answer. 
Result so far: 12293.0
The remainder is 470 after subtracting 1908 from 2378.
Fetch the next digit (0) from the dividend, attach it to 470 and continue: 4700 / 636

Going ahead to step 8:
If we divide 4700 by 636, we get 7 and a remainder of 248.
The number 7 becomes the next digit in our result. 
Result so far: 122937.0
If we take 4452 away from 4700, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 9:
636 can be fit into 2480 3 times, resulting in a remainder of 572.
The next digit of our result is 3. 
Result so far: 122937.3
Deduct 1908 from 2480 and we're left with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Going ahead to step 10:
When dividing 5720 by 636, we get 8 with a remainder of 632.
Write down 8 as next digit of the result. 
Result so far: 122937.38
Deduct 5088 from 5720 and we're left with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Let's proceed to step 11:
6320 divided by 636 is 9 with a remainder of 596.
Record the quotient 9 as the next digit in the result. 
Result so far: 122937.389
Subtracting 5724 from 6320 leaves us with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Moving on to step 12:
If we divide 5960 by 636, we get 9 and a remainder of 236.
Record the quotient 9 as the next digit in the result. 
Result so far: 122937.3899
If we subtract 5724 from 5960, we get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

The final outcome is 122937.3899, with a leftover of 0.00236.
