We're dividing 166484 by 20 
The aim is to understand the frequency of 20 in 166484.

Going ahead to step 1:
The number 20 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 20

Advancing to step 2:
The number 20 fits into 16 0 times, leaving a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 20

Going ahead to step 3:
When dividing 166 by 20, we get 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 160 from 166, we get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 20

Let's proceed to step 4:
20 can be fit into 64 3 times, resulting in a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
Deduct 60 from 64 and we're left with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 20

Advancing to step 5:
20 can be fit into 48 2 times, resulting in a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 832.0
Subtracting 40 from 48 leaves us with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 20

Step 6:
The number 20 fits into 84 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 8324.0
Subtracting 80 from 84 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
If we divide 40 by 20, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 8324.2
Subtracting 40 from 40 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.

Let's proceed to step 8:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8324.2
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.

On to step 9:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8324.2
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.

The quotient of the division is 8324.2, and the remainder is 0.0.
