We divide 746291 by 20
The aim is to understand the frequency of 20 in 746291.

Advancing to step 1:
When dividing 7 by 20, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 20

On to step 2:
74 divided by 20 is 3 with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 60 from 74 leaves us with 14.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 20

Step 3:
When dividing 146 by 20, we get 7 with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Deduct 140 from 146 and we're left with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 20

Let's proceed to step 4:
When dividing 62 by 20, we get 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 373.0
The remainder is 2 after subtracting 60 from 62.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 20

Advancing to step 5:
The number 20 fits into 29 1 times, leaving a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 3731.0
Subtract 20 from 29 to get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 20

Let's proceed to step 6:
When dividing 91 by 20, we get 4 with a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 37314.0
If we take 80 away from 91, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
20 can be fit into 110 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 37314.5
Subtract 100 from 110 to get 10.
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:
100 divided by 20 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 37314.55
If we subtract 100 from 100, we 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 37314.55 and a remainder of 0.0.
