100418 divided by 80 
We're looking to find how many times 80 goes into 100418.

On to step 1:
80 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 80

Moving on to step 2:
10 divided by 80 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 80

Moving on to step 3:
The number 80 fits into 100 1 times, leaving a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 80 from 100 to get 20.
Bring next digit (4) of the dividend behind the 20 and repeat the process: 204 / 80

On to step 4:
204 divided by 80 is 2 with a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 160 from 204 leaves us with 44.
Grab the next digit (1) from the dividend, add it to 44, then carry on: 441 / 80

Step 5:
If we divide 441 by 80, we get 5 and a remainder of 41.
Write down 5 as next digit of the result. 
Result so far: 125.0
If we take 400 away from 441, we end up with 41.
Take the next digit (8) from the dividend and append it to 41, then repeat: 418 / 80

Step 6:
80 can be fit into 418 5 times, resulting in a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 1255.0
Subtract 400 from 418 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
When dividing 180 by 80, we get 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 1255.2
Subtracting 160 from 180 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
200 divided by 80 is 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 1255.22
If we take 160 away from 200, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 1255.22 with a remainder of 0.04.
