Let's divide 11742559 by 80
We're looking to find how many times 80 goes into 11742559.

Let's proceed 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 take 0 away from 1, we end up with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 80

Advancing to step 2:
80 goes into 11 0 times with a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 11 to get 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 80

Moving on to step 3:
If we divide 117 by 80, we get 1 and a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 80 from 117, we get 37.
Fetch the next digit (4) from the dividend, attach it to 37 and continue: 374 / 80

Moving on to step 4:
80 goes into 374 4 times with a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 14.0
The remainder is 54 after subtracting 320 from 374.
Append the next digit (2) from the dividend to 54 and continue with: 542 / 80

Advancing to step 5:
If we divide 542 by 80, we get 6 and a remainder of 62.
The next digit of our result is 6. 
Result so far: 146.0
If we subtract 480 from 542, we get 62.
Fetch the next digit (5) from the dividend, attach it to 62 and continue: 625 / 80

Going ahead to step 6:
When dividing 625 by 80, we get 7 with a remainder of 65.
The number 7 becomes the next digit in our result. 
Result so far: 1467.0
If we take 560 away from 625, we end up with 65.
Grab the next digit (5) from the dividend, add it to 65, then carry on: 655 / 80

Moving on to step 7:
When dividing 655 by 80, we get 8 with a remainder of 15.
Put 8 as the next digit of the answer. 
Result so far: 14678.0
If we subtract 640 from 655, we get 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 80

Let's proceed to step 8:
159 divided by 80 is 1 with a remainder of 79.
The next digit of our result is 1. 
Result so far: 146781.0
If we take 80 away from 159, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 9:
80 goes into 790 9 times with a remainder of 70.
The next digit of our result is 9. 
Result so far: 146781.9
If we take 720 away from 790, we end up 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.

On to step 10:
80 can be fit into 700 8 times, resulting in a remainder of 60.
The next digit of our result is 8. 
Result so far: 146781.98
Deduct 640 from 700 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.

On to step 11:
When dividing 600 by 80, we get 7 with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 146781.987
Subtract 560 from 600 to 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.

Advancing to step 12:
80 goes into 400 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 146781.9875
Deduct 400 from 400 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 13:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 146781.9875
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 14:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 146781.9875
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.

The final result is 146781.9875 with a remainder of 0.0.
