61790246 ÷ 20 
The aim is to understand the frequency of 20 in 61790246.

Advancing to step 1:
6 divided by 20 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 20

Moving on to step 2:
When dividing 61 by 20, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 60 from 61 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 20

Let's proceed to step 3:
20 goes into 17 0 times with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 30.0
The remainder is 17 after subtracting 0 from 17.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 20

Going ahead to step 4:
20 goes into 179 8 times with a remainder of 19.
The number 8 becomes the next digit in our result. 
Result so far: 308.0
Deduct 160 from 179 and we're left with 19.
Grab the next digit (0) from the dividend, add it to 19, then carry on: 190 / 20

Advancing to step 5:
20 goes into 190 9 times with a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 3089.0
Deduct 180 from 190 and we're left with 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 20

Moving on to step 6:
The number 20 fits into 102 5 times, leaving a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 30895.0
Subtract 100 from 102 to get 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 20

On to step 7:
20 can be fit into 24 1 times, resulting in a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 308951.0
The remainder is 4 after subtracting 20 from 24.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 20

Advancing to step 8:
20 goes into 46 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 3089512.0
If we take 40 away from 46, we end up 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.

Going ahead to step 9:
The number 20 fits into 60 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3089512.3
Subtract 60 from 60 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.

On to 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: 3089512.3
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.

Let's proceed to step 11:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 3089512.3
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.

In conclusion, the division gives 3089512.3 with a balance of 0.0.
