We divide 140758 by 80
The aim is to understand the frequency of 80 in 140758.

On to step 1:
1 divided by 80 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 80

Step 2:
The number 80 fits into 14 0 times, leaving a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 80

Moving on to step 3:
If we divide 140 by 80, we get 1 and a remainder of 60.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 80 from 140, we get 60.
Append the next digit (7) from the dividend to 60 and continue with: 607 / 80

Let's proceed to step 4:
When dividing 607 by 80, we get 7 with a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 17.0
Deduct 560 from 607 and we're left with 47.
Fetch the next digit (5) from the dividend, attach it to 47 and continue: 475 / 80

Step 5:
80 goes into 475 5 times with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 175.0
If we subtract 400 from 475, we get 75.
Grab the next digit (8) from the dividend, add it to 75, then carry on: 758 / 80

Step 6:
When dividing 758 by 80, we get 9 with a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 1759.0
If we take 720 away from 758, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 7:
The number 80 fits into 380 4 times, leaving a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 1759.4
Subtract 320 from 380 to 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.

On to step 8:
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: 1759.47
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.

On to step 9:
When dividing 400 by 80, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1759.475
Subtract 400 from 400 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.

On to step 10:
When dividing 0 by 80, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1759.475
Subtracting 0 from 0 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.

On to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1759.475
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.

The quotient of the division is 1759.475, and the remainder is 0.0.
