We divide 852906 by 20
The aim is to understand the frequency of 20 in 852906.

Advancing to step 1:
When dividing 8 by 20, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 20

Going ahead to step 2:
If we divide 85 by 20, we get 4 and a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 80 from 85, we get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 20

Going ahead to step 3:
52 divided by 20 is 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 42.0
Subtract 40 from 52 to get 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 20

Advancing to step 4:
20 goes into 129 6 times with a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 426.0
Subtracting 120 from 129 leaves us with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 20

Going ahead to step 5:
When dividing 90 by 20, we get 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 4264.0
Deduct 80 from 90 and we're left with 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 20

Moving on to step 6:
When dividing 106 by 20, we get 5 with a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 42645.0
Deduct 100 from 106 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.

On to step 7:
If we divide 60 by 20, we get 3 and a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 42645.3
Subtracting 60 from 60 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.

Moving on to step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 42645.3
Subtracting 0 from 0 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.

Advancing to 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: 42645.3
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.

The final result is 42645.3 with a remainder of 0.0.
