963564 divided by 20 
The aim is to understand the frequency of 20 in 963564.

Let's proceed to step 1:
When dividing 9 by 20, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 20

Going ahead to step 2:
The number 20 fits into 96 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 80 from 96 to get 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 20

Moving on to step 3:
163 divided by 20 is 8 with a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 48.0
Subtracting 160 from 163 leaves us with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 20

Advancing to step 4:
The number 20 fits into 35 1 times, leaving a remainder of 15.
The next digit of our result is 1. 
Result so far: 481.0
If we take 20 away from 35, we end up with 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 20

Let's proceed to step 5:
20 goes into 156 7 times with a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 4817.0
Subtract 140 from 156 to get 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 20

Going ahead to step 6:
20 can be fit into 164 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 48178.0
If we subtract 160 from 164, we 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.

Going ahead to step 7:
If we divide 40 by 20, we get 2 and a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 48178.2
If we take 40 away from 40, 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.

Advancing to step 8:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 48178.2
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.

Let's proceed to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 48178.2
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.

The quotient of the division is 48178.2, and the remainder is 0.0.
