We divide 81199 by 80
We want to figure out the number of times 81199 can be divided by 80.

Advancing to step 1:
The number 80 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 80

Going ahead to step 2:
80 goes into 81 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 80 away from 81, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 80

Going ahead to step 3:
80 can be fit into 11 0 times, resulting in a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 11, we end up with 11.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 80

Advancing to step 4:
80 goes into 119 1 times with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 101.0
If we take 80 away from 119, we end up with 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 80

On to step 5:
80 goes into 399 4 times with a remainder of 79.
Record the quotient 4 as the next digit in the result. 
Result so far: 1014.0
If we subtract 320 from 399, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 6:
80 can be fit into 790 9 times, resulting in a remainder of 70.
Put 9 as the next digit of the answer. 
Result so far: 1014.9
Subtracting 720 from 790 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 7:
If we divide 700 by 80, we get 8 and a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 1014.98
Subtracting 640 from 700 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
If we divide 600 by 80, we get 7 and a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 1014.987
If we subtract 560 from 600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
When dividing 400 by 80, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 1014.9875
The remainder is 0 after subtracting 400 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1014.9875
If we subtract 0 from 0, we 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.

Going ahead to step 11:
80 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1014.9875
If we subtract 0 from 0, we 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.

The final outcome is 1014.9875, with a leftover of 0.0.
