Let's divide 75902930 by 817
The aim is to understand the frequency of 817 in 75902930.

Going ahead to step 1:
If we divide 7 by 817, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 817

Let's proceed to step 2:
When dividing 75 by 817, we get 0 with a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Grab the next digit (9) from the dividend, add it to 75, then carry on: 759 / 817

Step 3:
When dividing 759 by 817, we get 0 with a remainder of 759.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 759 leaves us with 759.
Append the next digit (0) from the dividend to 759 and continue with: 7590 / 817

Advancing to step 4:
7590 divided by 817 is 9 with a remainder of 237.
The next digit of our result is 9. 
Result so far: 9.0
If we take 7353 away from 7590, we end up with 237.
Append the next digit (2) from the dividend to 237 and continue with: 2372 / 817

Moving on to step 5:
817 can be fit into 2372 2 times, resulting in a remainder of 738.
Use 2 as the next digit of our solution. 
Result so far: 92.0
The remainder is 738 after subtracting 1634 from 2372.
Include the next digit (9) from the dividend after 738, then repeat: 7389 / 817

Advancing to step 6:
817 can be fit into 7389 9 times, resulting in a remainder of 36.
Put 9 as the next digit of the answer. 
Result so far: 929.0
Subtracting 7353 from 7389 leaves us with 36.
Bring next digit (3) of the dividend behind the 36 and repeat the process: 363 / 817

Let's proceed to step 7:
If we divide 363 by 817, we get 0 and a remainder of 363.
Put 0 as the next digit of the answer. 
Result so far: 9290.0
Subtracting 0 from 363 leaves us with 363.
Append the next digit (0) from the dividend to 363 and continue with: 3630 / 817

Moving on to step 8:
817 can be fit into 3630 4 times, resulting in a remainder of 362.
Put 4 as the next digit of the answer. 
Result so far: 92904.0
If we take 3268 away from 3630, we end up with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Moving on to step 9:
817 can be fit into 3620 4 times, resulting in a remainder of 352.
Record the quotient 4 as the next digit in the result. 
Result so far: 92904.4
If we subtract 3268 from 3620, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 10:
3520 divided by 817 is 4 with a remainder of 252.
Put 4 as the next digit of the answer. 
Result so far: 92904.44
If we subtract 3268 from 3520, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

The quotient of the division is 92904.44, and the remainder is 0.252.
