177179 divided by 20 
The aim is to understand the frequency of 20 in 177179.

Advancing to step 1:
If we divide 1 by 20, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 20

Going ahead to step 2:
The number 20 fits into 17 0 times, leaving a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 20

On to step 3:
The number 20 fits into 177 8 times, leaving a remainder of 17.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 160 from 177 leaves us with 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 20

Moving on to step 4:
If we divide 171 by 20, we get 8 and a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
Deduct 160 from 171 and we're left with 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 20

On to step 5:
When dividing 117 by 20, we get 5 with a remainder of 17.
The next digit of our result is 5. 
Result so far: 885.0
The remainder is 17 after subtracting 100 from 117.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 20

Moving on to step 6:
179 divided by 20 is 8 with a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 8858.0
If we take 160 away from 179, we end up 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.

Moving on to step 7:
The number 20 fits into 190 9 times, leaving a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 8858.9
Subtracting 180 from 190 leaves us 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.

Let's proceed to step 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 8858.95
Subtract 100 from 100 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.

Going ahead 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: 8858.95
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.

Moving on to step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8858.95
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.

The final result is 8858.95 with a remainder of 0.0.
