931393 divided by 80 
The aim is to understand the frequency of 80 in 931393.

Let's proceed to step 1:
80 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 80

Advancing to step 2:
The number 80 fits into 93 1 times, leaving a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 80 from 93 and we're left with 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 80

Moving on to step 3:
When dividing 131 by 80, we get 1 with a remainder of 51.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 80 from 131 leaves us with 51.
Grab the next digit (3) from the dividend, add it to 51, then carry on: 513 / 80

Going ahead to step 4:
80 goes into 513 6 times with a remainder of 33.
Use 6 as the next digit of our solution. 
Result so far: 116.0
Deduct 480 from 513 and we're left with 33.
Bring next digit (9) of the dividend behind the 33 and repeat the process: 339 / 80

Moving on to step 5:
If we divide 339 by 80, we get 4 and a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 1164.0
Subtract 320 from 339 to get 19.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 80

Advancing to step 6:
The number 80 fits into 193 2 times, leaving a remainder of 33.
The next digit of our result is 2. 
Result so far: 11642.0
The remainder is 33 after subtracting 160 from 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 7:
When dividing 330 by 80, we get 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 11642.4
The remainder is 10 after subtracting 320 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
If we divide 100 by 80, we get 1 and a remainder of 20.
The next digit of our result is 1. 
Result so far: 11642.41
The remainder is 20 after subtracting 80 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
200 divided by 80 is 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 11642.412
If we take 160 away from 200, 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:
When dividing 400 by 80, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 11642.4125
If we subtract 400 from 400, 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.

Moving on to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 11642.4125
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.

Moving on to step 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11642.4125
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 11642.4125, and the remainder is 0.0.
