We divide 612859 by 20
The aim is to understand the frequency of 20 in 612859.

Moving on to step 1:
20 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 20

Step 2:
If we divide 61 by 20, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 60 from 61 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 20

On to step 3:
12 divided by 20 is 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 30.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 20

Advancing to step 4:
128 divided by 20 is 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 306.0
Subtract 120 from 128 to get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 20

Let's proceed to step 5:
20 goes into 85 4 times with a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 3064.0
Subtract 80 from 85 to get 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 20

Going ahead to step 6:
If we divide 59 by 20, we get 2 and a remainder of 19.
Write down 2 as next digit of the result. 
Result so far: 30642.0
Subtracting 40 from 59 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
20 can be fit into 190 9 times, resulting in a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 30642.9
If we take 180 away from 190, we end up 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:
When dividing 100 by 20, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 30642.95
The remainder is 0 after subtracting 100 from 100.
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 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 30642.95
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.

Let's proceed to step 10:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 30642.95
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 quotient of the division is 30642.95, and the remainder is 0.0.
