We look at the division of 252158 by 80 
The aim is to understand the frequency of 80 in 252158.

Moving on to step 1:
2 divided by 80 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 80

Going ahead to step 2:
The number 80 fits into 25 0 times, leaving a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Fetch the next digit (2) from the dividend, attach it to 25 and continue: 252 / 80

Let's proceed to step 3:
80 goes into 252 3 times with a remainder of 12.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 240 from 252 to get 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 80

Advancing to step 4:
If we divide 121 by 80, we get 1 and a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we subtract 80 from 121, we get 41.
Take the next digit (5) from the dividend and append it to 41, then repeat: 415 / 80

Advancing to step 5:
If we divide 415 by 80, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 315.0
Subtract 400 from 415 to get 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 80

On to step 6:
80 goes into 158 1 times with a remainder of 78.
The next digit of our result is 1. 
Result so far: 3151.0
Subtract 80 from 158 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 7:
780 divided by 80 is 9 with a remainder of 60.
Put 9 as the next digit of the answer. 
Result so far: 3151.9
If we subtract 720 from 780, 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.

Let's proceed to step 8:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 3151.97
Subtracting 560 from 600 leaves us 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.

Advancing 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: 3151.975
If we take 400 away from 400, 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.

Let's proceed to step 10:
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: 3151.975
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:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 3151.975
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.

After the division, we end up with 3151.975 and a remainder of 0.0.
