We divide 165286 by 20
The aim is to understand the frequency of 20 in 165286.

Step 1:
20 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 20

On to step 2:
20 can be fit into 16 0 times, resulting in a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 20

Going ahead to step 3:
If we divide 165 by 20, we get 8 and a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 160 from 165 to get 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 20

Moving on to step 4:
52 divided by 20 is 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
Subtract 40 from 52 to get 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 20

Moving on to step 5:
20 can be fit into 128 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 826.0
If we take 120 away from 128, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 20

Moving on to step 6:
86 divided by 20 is 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 8264.0
Deduct 80 from 86 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
20 can be fit into 60 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 8264.3
Deduct 60 from 60 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.

On to step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8264.3
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.

Step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 8264.3
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 final outcome is 8264.3, with a leftover of 0.0.
