174899 divided by 20 
The aim is to understand the frequency of 20 in 174899.

On to step 1:
20 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 20

Step 2:
The number 20 fits into 17 0 times, leaving a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 20

Step 3:
The number 20 fits into 174 8 times, leaving a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 160 from 174, we get 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 20

Moving on to step 4:
When dividing 148 by 20, we get 7 with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 87.0
Subtracting 140 from 148 leaves us with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 20

Advancing to step 5:
20 can be fit into 89 4 times, resulting in a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 874.0
If we take 80 away from 89, we end up with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 20

Step 6:
The number 20 fits into 99 4 times, leaving a remainder of 19.
Put 4 as the next digit of the answer. 
Result so far: 8744.0
Deduct 80 from 99 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
20 can be fit into 190 9 times, resulting in a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 8744.9
Subtract 180 from 190 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 8744.95
Deduct 100 from 100 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 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8744.95
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.

Let's proceed to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 8744.95
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.

After the division, we end up with 8744.95 and a remainder of 0.0.
