993962 ÷ 20 
The aim is to understand the frequency of 20 in 993962.

On to step 1:
20 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 20

Let's proceed to step 2:
When dividing 99 by 20, we get 4 with a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 80 from 99 leaves us with 19.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 20

Moving on to step 3:
If we divide 193 by 20, we get 9 and a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 49.0
Subtract 180 from 193 to get 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 20

On to step 4:
139 divided by 20 is 6 with a remainder of 19.
Record the quotient 6 as the next digit in the result. 
Result so far: 496.0
Deduct 120 from 139 and we're left with 19.
Grab the next digit (6) from the dividend, add it to 19, then carry on: 196 / 20

Advancing to step 5:
196 divided by 20 is 9 with a remainder of 16.
The next digit of our result is 9. 
Result so far: 4969.0
Deduct 180 from 196 and we're left with 16.
Take the next digit (2) from the dividend and append it to 16, then repeat: 162 / 20

On to step 6:
20 can be fit into 162 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 49698.0
The remainder is 2 after subtracting 160 from 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
When dividing 20 by 20, we get 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 49698.1
Subtracting 20 from 20 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.

Let's proceed to step 8:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 49698.1
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.

On to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 49698.1
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.

The final result is 49698.1 with a remainder of 0.0.
