We divide 198010 by 80
The aim is to understand the frequency of 80 in 198010.

Going ahead to step 1:
When dividing 1 by 80, we get 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.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 80

Going ahead to step 2:
When dividing 19 by 80, we get 0 with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 80

Let's proceed to step 3:
When dividing 198 by 80, we get 2 with a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 38 after subtracting 160 from 198.
Grab the next digit (0) from the dividend, add it to 38, then carry on: 380 / 80

Going ahead to step 4:
80 goes into 380 4 times with a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
The remainder is 60 after subtracting 320 from 380.
Append the next digit (1) from the dividend to 60 and continue with: 601 / 80

Step 5:
601 divided by 80 is 7 with a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 247.0
Subtracting 560 from 601 leaves us with 41.
Fetch the next digit (0) from the dividend, attach it to 41 and continue: 410 / 80

Step 6:
If we divide 410 by 80, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 2475.0
Deduct 400 from 410 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
80 goes into 100 1 times with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 2475.1
If we take 80 away from 100, we end up with 20.
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 8:
80 goes into 200 2 times with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 2475.12
If we subtract 160 from 200, we 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.

Let's proceed to step 9:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 2475.125
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:
When dividing 0 by 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2475.125
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.

Going ahead to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2475.125
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 final result is 2475.125 with a remainder of 0.0.
