76019 ÷ 20 
The aim is to understand the frequency of 20 in 76019.

Step 1:
7 divided by 20 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 20

Moving on to step 2:
When dividing 76 by 20, we get 3 with a remainder of 16.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 60 from 76 leaves us with 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 20

On to step 3:
If we divide 160 by 20, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 38.0
If we subtract 160 from 160, we get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 20

Moving on to step 4:
If we divide 1 by 20, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 380.0
Subtract 0 from 1 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 20

Step 5:
When dividing 19 by 20, we get 0 with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 3800.0
Subtracting 0 from 19 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 6:
The number 20 fits into 190 9 times, leaving a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 3800.9
Subtract 180 from 190 to get 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 7:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 3800.95
Subtracting 100 from 100 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:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 3800.95
If we subtract 0 from 0, 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.

Moving on to step 9:
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: 3800.95
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.

The final outcome is 3800.95, with a leftover of 0.0.
