939791 divided by 80 
We want to figure out the number of times 939791 can be divided by 80.

Let's proceed to step 1:
The number 80 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 80

Advancing to step 2:
The number 80 fits into 93 1 times, leaving a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 80 from 93 leaves us with 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 80

Let's proceed to step 3:
80 goes into 139 1 times with a remainder of 59.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 59 after subtracting 80 from 139.
Grab the next digit (7) from the dividend, add it to 59, then carry on: 597 / 80

Advancing to step 4:
80 goes into 597 7 times with a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
If we subtract 560 from 597, we get 37.
Fetch the next digit (9) from the dividend, attach it to 37 and continue: 379 / 80

Let's proceed to step 5:
When dividing 379 by 80, we get 4 with a remainder of 59.
Use 4 as the next digit of our solution. 
Result so far: 1174.0
Subtract 320 from 379 to get 59.
Bring next digit (1) of the dividend behind the 59 and repeat the process: 591 / 80

Let's proceed to step 6:
When dividing 591 by 80, we get 7 with a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 11747.0
Deduct 560 from 591 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
310 divided by 80 is 3 with a remainder of 70.
Record the quotient 3 as the next digit in the result. 
Result so far: 11747.3
The remainder is 70 after subtracting 240 from 310.
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 8:
If we divide 700 by 80, we get 8 and a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 11747.38
If we subtract 640 from 700, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
When dividing 600 by 80, we get 7 with a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 11747.387
If we take 560 away from 600, we end up 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.

Let's proceed to step 10:
80 goes into 400 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 11747.3875
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.

Moving on to step 11:
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: 11747.3875
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.

Advancing to step 12:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11747.3875
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 quotient of the division is 11747.3875, and the remainder is 0.0.
