We look at the division of 583135 by 20 
The aim is to understand the frequency of 20 in 583135.

On to step 1:
When dividing 5 by 20, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 20

Advancing to step 2:
20 goes into 58 2 times with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 40 away from 58, we end up with 18.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 20

Let's proceed to step 3:
When dividing 183 by 20, we get 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
If we take 180 away from 183, we end up with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 20

Moving on to step 4:
31 divided by 20 is 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 291.0
The remainder is 11 after subtracting 20 from 31.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 20

Step 5:
The number 20 fits into 113 5 times, leaving a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 2915.0
Subtract 100 from 113 to get 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 20

Moving on to step 6:
20 can be fit into 135 6 times, resulting in a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 29156.0
The remainder is 15 after subtracting 120 from 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
The number 20 fits into 150 7 times, leaving a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 29156.7
Deduct 140 from 150 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.

Moving on to step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 29156.75
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:
When dividing 0 by 20, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 29156.75
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.

Advancing to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 29156.75
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.

After the division, we end up with 29156.75 and a remainder of 0.0.
