Let's divide 867225 by 20
The aim is to understand the frequency of 20 in 867225.

Step 1:
If we divide 8 by 20, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 20

Advancing to step 2:
When dividing 86 by 20, we get 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 80 from 86 and we're left with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 20

Going ahead to step 3:
The number 20 fits into 67 3 times, leaving a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 43.0
The remainder is 7 after subtracting 60 from 67.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 20

On to step 4:
If we divide 72 by 20, we get 3 and a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 433.0
If we take 60 away from 72, we end up with 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 20

On to step 5:
122 divided by 20 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 4336.0
Subtracting 120 from 122 leaves us with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 20

Advancing to step 6:
20 can be fit into 25 1 times, resulting in a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 43361.0
Subtract 20 from 25 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
The number 20 fits into 50 2 times, leaving a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 43361.2
The remainder is 10 after subtracting 40 from 50.
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 goes into 100 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 43361.25
Subtracting 100 from 100 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.

On to step 9:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 43361.25
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.

Step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 43361.25
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 43361.25 with a remainder of 0.0.
