113891 divided by 80 
Our goal is to divide 113891 by 80.

Advancing to step 1:
When dividing 1 by 80, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 80

Advancing to step 2:
11 divided by 80 is 0 with a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 80

Advancing to step 3:
80 can be fit into 113 1 times, resulting in a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 80 from 113, we get 33.
Grab the next digit (8) from the dividend, add it to 33, then carry on: 338 / 80

Advancing to step 4:
When dividing 338 by 80, we get 4 with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 320 from 338, we get 18.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 80

Let's proceed to step 5:
When dividing 189 by 80, we get 2 with a remainder of 29.
The number 2 becomes the next digit in our result. 
Result so far: 142.0
The remainder is 29 after subtracting 160 from 189.
Take the next digit (1) from the dividend and append it to 29, then repeat: 291 / 80

Advancing to step 6:
When dividing 291 by 80, we get 3 with a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 1423.0
If we take 240 away from 291, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 7:
510 divided by 80 is 6 with a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 1423.6
The remainder is 30 after subtracting 480 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
If we divide 300 by 80, we get 3 and a remainder of 60.
The number 3 becomes the next digit in our result. 
Result so far: 1423.63
Subtracting 240 from 300 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.

Let's proceed to step 9:
The number 80 fits into 600 7 times, leaving a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 1423.637
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
80 goes into 400 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1423.6375
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.

Step 11:
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: 1423.6375
Deduct 0 from 0 and we're left 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.

Step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1423.6375
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 quotient of the division is 1423.6375, and the remainder is 0.0.
