We divide 996024 by 20
The aim is to understand the frequency of 20 in 996024.

Moving on to step 1:
9 divided by 20 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 20

Advancing to step 2:
99 divided by 20 is 4 with a remainder of 19.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 80 from 99 and we're left with 19.
Fetch the next digit (6) from the dividend, attach it to 19 and continue: 196 / 20

Step 3:
When dividing 196 by 20, we get 9 with a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 49.0
If we subtract 180 from 196, we get 16.
Take the next digit (0) from the dividend and append it to 16, then repeat: 160 / 20

Going ahead to step 4:
160 divided by 20 is 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 498.0
If we subtract 160 from 160, we get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 20

Advancing to step 5:
2 divided by 20 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 4980.0
If we subtract 0 from 2, we get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 20

Step 6:
The number 20 fits into 24 1 times, leaving a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 49801.0
Subtract 20 from 24 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
20 goes into 40 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 49801.2
Deduct 40 from 40 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.

Moving on to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 49801.2
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:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 49801.2
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.

Our division results in 49801.2 with a remaining 0.0.
