45835 ÷ 80 
The aim is to understand the frequency of 80 in 45835.

Advancing to step 1:
4 divided by 80 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 80

Going ahead to step 2:
80 goes into 45 0 times with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Fetch the next digit (8) from the dividend, attach it to 45 and continue: 458 / 80

Advancing to step 3:
458 divided by 80 is 5 with a remainder of 58.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 400 from 458 to get 58.
Append the next digit (3) from the dividend to 58 and continue with: 583 / 80

Step 4:
80 goes into 583 7 times with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 57.0
If we take 560 away from 583, we end up with 23.
Grab the next digit (5) from the dividend, add it to 23, then carry on: 235 / 80

Step 5:
If we divide 235 by 80, we get 2 and a remainder of 75.
The next digit of our result is 2. 
Result so far: 572.0
If we subtract 160 from 235, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 6:
If we divide 750 by 80, we get 9 and a remainder of 30.
The next digit of our result is 9. 
Result so far: 572.9
If we take 720 away from 750, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 7:
300 divided by 80 is 3 with a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 572.93
Subtract 240 from 300 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:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 572.937
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.

Going ahead to step 9:
400 divided by 80 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 572.9375
Subtracting 400 from 400 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.

Going ahead to step 10:
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: 572.9375
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.

On to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 572.9375
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.

Our division results in 572.9375 with a remaining 0.0.
