18115019 ÷ 117 
Let's see how many times 117 fits into 18115019.

Going ahead to step 1:
1 divided by 117 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 117

Going ahead to step 2:
The number 117 fits into 18 0 times, leaving a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 117

Advancing to step 3:
The number 117 fits into 181 1 times, leaving a remainder of 64.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 117 from 181, we get 64.
Take the next digit (1) from the dividend and append it to 64, then repeat: 641 / 117

On to step 4:
117 goes into 641 5 times with a remainder of 56.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 585 away from 641, we end up with 56.
Grab the next digit (5) from the dividend, add it to 56, then carry on: 565 / 117

On to step 5:
565 divided by 117 is 4 with a remainder of 97.
The next digit of our result is 4. 
Result so far: 154.0
Subtracting 468 from 565 leaves us with 97.
Bring next digit (0) of the dividend behind the 97 and repeat the process: 970 / 117

Going ahead to step 6:
117 can be fit into 970 8 times, resulting in a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 1548.0
If we subtract 936 from 970, we get 34.
Append the next digit (1) from the dividend to 34 and continue with: 341 / 117

Moving on to step 7:
117 can be fit into 341 2 times, resulting in a remainder of 107.
The number 2 becomes the next digit in our result. 
Result so far: 15482.0
Deduct 234 from 341 and we're left with 107.
Bring next digit (9) of the dividend behind the 107 and repeat the process: 1079 / 117

On to step 8:
When dividing 1079 by 117, we get 9 with a remainder of 26.
The next digit of our result is 9. 
Result so far: 154829.0
Subtracting 1053 from 1079 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 9:
117 goes into 260 2 times with a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 154829.2
If we take 234 away from 260, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 10:
260 divided by 117 is 2 with a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 154829.22
If we subtract 234 from 260, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

After the division, we end up with 154829.22 and a remainder of 0.026.
