Let's divide 20023602 by 817
The aim is to understand the frequency of 817 in 20023602.

Advancing to step 1:
817 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 817

Step 2:
If we divide 20 by 817, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 817

Going ahead to step 3:
When dividing 200 by 817, we get 0 with a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 200, we get 200.
Bring next digit (2) of the dividend behind the 200 and repeat the process: 2002 / 817

Going ahead to step 4:
The number 817 fits into 2002 2 times, leaving a remainder of 368.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1634 from 2002 and we're left with 368.
Bring next digit (3) of the dividend behind the 368 and repeat the process: 3683 / 817

On to step 5:
817 can be fit into 3683 4 times, resulting in a remainder of 415.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Deduct 3268 from 3683 and we're left with 415.
Take the next digit (6) from the dividend and append it to 415, then repeat: 4156 / 817

On to step 6:
The number 817 fits into 4156 5 times, leaving a remainder of 71.
Use 5 as the next digit of our solution. 
Result so far: 245.0
Deduct 4085 from 4156 and we're left with 71.
Include the next digit (0) from the dividend after 71, then repeat: 710 / 817

Moving on to step 7:
When dividing 710 by 817, we get 0 with a remainder of 710.
Put 0 as the next digit of the answer. 
Result so far: 2450.0
Subtract 0 from 710 to get 710.
Include the next digit (2) from the dividend after 710, then repeat: 7102 / 817

Let's proceed to step 8:
When dividing 7102 by 817, we get 8 with a remainder of 566.
Record the quotient 8 as the next digit in the result. 
Result so far: 24508.0
The remainder is 566 after subtracting 6536 from 7102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Moving on to step 9:
817 can be fit into 5660 6 times, resulting in a remainder of 758.
Write down 6 as next digit of the result. 
Result so far: 24508.6
Subtract 4902 from 5660 to get 758.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7580, and continue the process.

On to step 10:
When dividing 7580 by 817, we get 9 with a remainder of 227.
Put 9 as the next digit of the answer. 
Result so far: 24508.69
If we subtract 7353 from 7580, we get 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Advancing to step 11:
2270 divided by 817 is 2 with a remainder of 636.
Write down 2 as next digit of the result. 
Result so far: 24508.692
If we take 1634 away from 2270, we end up with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Advancing to step 12:
If we divide 6360 by 817, we get 7 and a remainder of 641.
The number 7 becomes the next digit in our result. 
Result so far: 24508.6927
If we take 5719 away from 6360, we end up with 641.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6410, and continue the process.

Going ahead to step 13:
The number 817 fits into 6410 7 times, leaving a remainder of 691.
Put 7 as the next digit of the answer. 
Result so far: 24508.69277
If we subtract 5719 from 6410, we get 691.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6910, and continue the process.

Our division results in 24508.69277 with a remaining 0.000691.
