178552 ÷ 20 
The aim is to understand the frequency of 20 in 178552.

Moving on to step 1:
If we divide 1 by 20, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 20

Going ahead to step 2:
When dividing 17 by 20, we get 0 with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 20

Let's proceed to step 3:
The number 20 fits into 178 8 times, leaving a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 160 from 178, we get 18.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 20

Moving on to step 4:
When dividing 185 by 20, we get 9 with a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 89.0
Subtract 180 from 185 to get 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 20

On to step 5:
20 goes into 55 2 times with a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 892.0
If we take 40 away from 55, we end up with 15.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 20

Let's proceed to step 6:
If we divide 152 by 20, we get 7 and a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 8927.0
The remainder is 12 after subtracting 140 from 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
When dividing 120 by 20, we get 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 8927.6
Subtract 120 from 120 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.

Moving on to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8927.6
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.

Advancing to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 8927.6
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 outcome is 8927.6, with a leftover of 0.0.
