We divide 154502 by 20
The aim is to understand the frequency of 20 in 154502.

Step 1:
20 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 20

On to step 2:
15 divided by 20 is 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 20

Going ahead to step 3:
154 divided by 20 is 7 with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 140 from 154 leaves us with 14.
Take the next digit (5) from the dividend and append it to 14, then repeat: 145 / 20

Let's proceed to step 4:
20 goes into 145 7 times with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 77.0
Subtract 140 from 145 to get 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 20

Going ahead to step 5:
20 can be fit into 50 2 times, resulting in a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 772.0
If we subtract 40 from 50, we get 10.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 20

Step 6:
The number 20 fits into 102 5 times, leaving a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 7725.0
Subtracting 100 from 102 leaves us 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 7:
20 can be fit into 20 1 times, resulting in a remainder of 0.
The next digit of our result is 1. 
Result so far: 7725.1
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 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7725.1
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.

Advancing to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7725.1
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 quotient of the division is 7725.1, and the remainder is 0.0.
