Let's divide 121361 by 20
The aim is to understand the frequency of 20 in 121361.

On to step 1:
When dividing 1 by 20, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 20

On to step 2:
The number 20 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 20

Step 3:
20 goes into 121 6 times with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 120 away from 121, we end up with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 20

Advancing to step 4:
The number 20 fits into 13 0 times, leaving a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 60.0
If we take 0 away from 13, we end up with 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 20

Step 5:
If we divide 136 by 20, we get 6 and a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 606.0
If we take 120 away from 136, we end up with 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 20

Going ahead to step 6:
161 divided by 20 is 8 with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 6068.0
If we subtract 160 from 161, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
The number 20 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 6068.0
Deduct 0 from 10 and we're left 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.

Going ahead to step 8:
20 goes into 100 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 6068.05
If we subtract 100 from 100, we 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.

Let's proceed to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6068.05
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 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6068.05
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 result is 6068.05 with a remainder of 0.0.
