We divide 161236 by 20
The aim is to understand the frequency of 20 in 161236.

Moving on to step 1:
20 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 20

Step 2:
When dividing 16 by 20, we get 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 20

Let's proceed to step 3:
20 can be fit into 161 8 times, resulting in a remainder of 1.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 160 from 161 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 20

Moving on to step 4:
If we divide 12 by 20, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
Subtracting 0 from 12 leaves us with 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 20

Going ahead to step 5:
If we divide 123 by 20, we get 6 and a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 806.0
Subtract 120 from 123 to get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 20

Advancing to step 6:
20 can be fit into 36 1 times, resulting in a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 8061.0
Deduct 20 from 36 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
When dividing 160 by 20, we get 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 8061.8
The remainder is 0 after subtracting 160 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8061.8
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.

Going ahead to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8061.8
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.

Our division results in 8061.8 with a remaining 0.0.
