93987173 divided by 80 
Let's see how many times 80 fits into 93987173.

Let's proceed to step 1:
The number 80 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 80

Advancing to step 2:
93 divided by 80 is 1 with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 13 after subtracting 80 from 93.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 80

Advancing to step 3:
If we divide 139 by 80, we get 1 and a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 80 away from 139, we end up with 59.
Include the next digit (8) from the dividend after 59, then repeat: 598 / 80

On to step 4:
80 can be fit into 598 7 times, resulting in a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 117.0
Subtract 560 from 598 to get 38.
Append the next digit (7) from the dividend to 38 and continue with: 387 / 80

On to step 5:
If we divide 387 by 80, we get 4 and a remainder of 67.
Write down 4 as next digit of the result. 
Result so far: 1174.0
Subtracting 320 from 387 leaves us with 67.
Fetch the next digit (1) from the dividend, attach it to 67 and continue: 671 / 80

Going ahead to step 6:
80 goes into 671 8 times with a remainder of 31.
Record the quotient 8 as the next digit in the result. 
Result so far: 11748.0
If we take 640 away from 671, we end up with 31.
Grab the next digit (7) from the dividend, add it to 31, then carry on: 317 / 80

Advancing to step 7:
The number 80 fits into 317 3 times, leaving a remainder of 77.
Put 3 as the next digit of the answer. 
Result so far: 117483.0
The remainder is 77 after subtracting 240 from 317.
Grab the next digit (3) from the dividend, add it to 77, then carry on: 773 / 80

Advancing to step 8:
80 can be fit into 773 9 times, resulting in a remainder of 53.
Write down 9 as next digit of the result. 
Result so far: 1174839.0
Deduct 720 from 773 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 9:
80 goes into 530 6 times with a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 1174839.6
If we subtract 480 from 530, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
If we divide 500 by 80, we get 6 and a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 1174839.66
If we subtract 480 from 500, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 1174839.66 with a remaining 0.02.
