We divide 18815856 by 80
We're looking to find how many times 80 goes into 18815856.

On to step 1:
1 divided by 80 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 80

Moving on to step 2:
The number 80 fits into 18 0 times, leaving a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 80

Going ahead to step 3:
188 divided by 80 is 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 160 from 188 leaves us with 28.
Bring next digit (1) of the dividend behind the 28 and repeat the process: 281 / 80

Going ahead to step 4:
80 goes into 281 3 times with a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Deduct 240 from 281 and we're left with 41.
Take the next digit (5) from the dividend and append it to 41, then repeat: 415 / 80

Going ahead to step 5:
When dividing 415 by 80, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 235.0
The remainder is 15 after subtracting 400 from 415.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 80

Step 6:
80 can be fit into 158 1 times, resulting in a remainder of 78.
Put 1 as the next digit of the answer. 
Result so far: 2351.0
Subtracting 80 from 158 leaves us with 78.
Append the next digit (5) from the dividend to 78 and continue with: 785 / 80

Going ahead to step 7:
When dividing 785 by 80, we get 9 with a remainder of 65.
The next digit of our result is 9. 
Result so far: 23519.0
The remainder is 65 after subtracting 720 from 785.
Bring next digit (6) of the dividend behind the 65 and repeat the process: 656 / 80

Advancing to step 8:
When dividing 656 by 80, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 235198.0
Subtracting 640 from 656 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
If we divide 160 by 80, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 235198.2
Subtracting 160 from 160 leaves us 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.

Let's proceed to step 10:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 235198.2
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
0 divided by 80 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 235198.2
Subtracting 0 from 0 leaves us 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 235198.2 with a remaining 0.0.
