96646542 divided by 20 
The aim is to understand the frequency of 20 in 96646542.

Step 1:
20 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 20

Let's proceed to step 2:
96 divided by 20 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 80 from 96 to get 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 20

Advancing to step 3:
166 divided by 20 is 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 48.0
Deduct 160 from 166 and we're left with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 20

Advancing to step 4:
20 can be fit into 64 3 times, resulting in a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 483.0
Deduct 60 from 64 and we're left with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 20

Let's proceed to step 5:
If we divide 46 by 20, we get 2 and a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 4832.0
Subtracting 40 from 46 leaves us with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 20

Let's proceed to step 6:
20 goes into 65 3 times with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 48323.0
If we subtract 60 from 65, we get 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 20

Moving on to step 7:
The number 20 fits into 54 2 times, leaving a remainder of 14.
The next digit of our result is 2. 
Result so far: 483232.0
Subtract 40 from 54 to get 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 20

On to step 8:
20 goes into 142 7 times with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 4832327.0
If we take 140 away from 142, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
If we divide 20 by 20, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 4832327.1
If we subtract 20 from 20, 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.

Going ahead to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4832327.1
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.

Step 11:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4832327.1
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.

Our division results in 4832327.1 with a remaining 0.0.
