Let's divide 146919 by 20
The aim is to understand the frequency of 20 in 146919.

Step 1:
20 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 20

Moving on to step 2:
The number 20 fits into 14 0 times, leaving a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 20

Let's proceed to step 3:
20 can be fit into 146 7 times, resulting in a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 6 after subtracting 140 from 146.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 20

Let's proceed to step 4:
When dividing 69 by 20, we get 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
Subtract 60 from 69 to get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 20

Going ahead to step 5:
20 can be fit into 91 4 times, resulting in a remainder of 11.
The next digit of our result is 4. 
Result so far: 734.0
If we subtract 80 from 91, we get 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 20

Advancing to step 6:
If we divide 119 by 20, we get 5 and a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 7345.0
The remainder is 19 after subtracting 100 from 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
20 goes into 190 9 times with a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 7345.9
If we take 180 away from 190, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 7345.95
Deduct 100 from 100 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.

Advancing to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7345.95
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 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7345.95
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.

The final outcome is 7345.95, with a leftover of 0.0.
