We look at the division of 112451 by 80 
We're looking to find how many times 80 goes into 112451.

Advancing to step 1:
If we divide 1 by 80, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 80

Step 2:
The number 80 fits into 11 0 times, leaving a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 80

Moving on to step 3:
112 divided by 80 is 1 with a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 80 from 112 leaves us with 32.
Include the next digit (4) from the dividend after 32, then repeat: 324 / 80

Advancing to step 4:
If we divide 324 by 80, we get 4 and a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we subtract 320 from 324, we get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 80

On to step 5:
80 can be fit into 45 0 times, resulting in a remainder of 45.
The next digit of our result is 0. 
Result so far: 140.0
Deduct 0 from 45 and we're left with 45.
Append the next digit (1) from the dividend to 45 and continue with: 451 / 80

Let's proceed to step 6:
If we divide 451 by 80, we get 5 and a remainder of 51.
The next digit of our result is 5. 
Result so far: 1405.0
The remainder is 51 after subtracting 400 from 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 7:
510 divided by 80 is 6 with a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 1405.6
Subtract 480 from 510 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
The number 80 fits into 300 3 times, leaving a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 1405.63
Deduct 240 from 300 and we're left 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.

Advancing to step 9:
600 divided by 80 is 7 with a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 1405.637
Subtracting 560 from 600 leaves us 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.

Going ahead to step 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 1405.6375
Subtracting 400 from 400 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.

Advancing to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1405.6375
If we take 0 away from 0, we end up 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.

Advancing to step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1405.6375
The remainder is 0 after subtracting 0 from 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 1405.6375, with a leftover of 0.0.
