Let's divide 75236321 by 817
The aim is to understand the frequency of 817 in 75236321.

Advancing to step 1:
7 divided by 817 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 817

Advancing to step 2:
75 divided by 817 is 0 with a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Take the next digit (2) from the dividend and append it to 75, then repeat: 752 / 817

Step 3:
817 goes into 752 0 times with a remainder of 752.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 752 after subtracting 0 from 752.
Append the next digit (3) from the dividend to 752 and continue with: 7523 / 817

Step 4:
817 goes into 7523 9 times with a remainder of 170.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 7353 from 7523, we get 170.
Append the next digit (6) from the dividend to 170 and continue with: 1706 / 817

Let's proceed to step 5:
When dividing 1706 by 817, we get 2 with a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 92.0
The remainder is 72 after subtracting 1634 from 1706.
Grab the next digit (3) from the dividend, add it to 72, then carry on: 723 / 817

Going ahead to step 6:
817 goes into 723 0 times with a remainder of 723.
Put 0 as the next digit of the answer. 
Result so far: 920.0
Subtracting 0 from 723 leaves us with 723.
Fetch the next digit (2) from the dividend, attach it to 723 and continue: 7232 / 817

Moving on to step 7:
817 goes into 7232 8 times with a remainder of 696.
Use 8 as the next digit of our solution. 
Result so far: 9208.0
Subtracting 6536 from 7232 leaves us with 696.
Append the next digit (1) from the dividend to 696 and continue with: 6961 / 817

Going ahead to step 8:
The number 817 fits into 6961 8 times, leaving a remainder of 425.
The number 8 becomes the next digit in our result. 
Result so far: 92088.0
Subtracting 6536 from 6961 leaves us with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Moving on to step 9:
When dividing 4250 by 817, we get 5 with a remainder of 165.
Use 5 as the next digit of our solution. 
Result so far: 92088.5
Subtracting 4085 from 4250 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Moving on to step 10:
When dividing 1650 by 817, we get 2 with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 92088.52
If we subtract 1634 from 1650, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
The number 817 fits into 160 0 times, leaving a remainder of 160.
The next digit of our result is 0. 
Result so far: 92088.52
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 12:
The number 817 fits into 1600 1 times, leaving a remainder of 783.
Write down 1 as next digit of the result. 
Result so far: 92088.5201
Deduct 817 from 1600 and we're left with 783.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7830, and continue the process.

Step 13:
When dividing 7830 by 817, we get 9 with a remainder of 477.
Record the quotient 9 as the next digit in the result. 
Result so far: 92088.52019
If we take 7353 away from 7830, we end up with 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Let's proceed to step 14:
When dividing 4770 by 817, we get 5 with a remainder of 685.
Write down 5 as next digit of the result. 
Result so far: 92088.520195
Deduct 4085 from 4770 and we're left with 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

On to step 15:
6850 divided by 817 is 8 with a remainder of 314.
Record the quotient 8 as the next digit in the result. 
Result so far: 92088.5201958
The remainder is 314 after subtracting 6536 from 6850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Going ahead to step 16:
3140 divided by 817 is 3 with a remainder of 689.
Put 3 as the next digit of the answer. 
Result so far: 92088.52019583
Deduct 2451 from 3140 and we're left with 689.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6890, and continue the process.

The quotient of the division is 92088.52019583, and the remainder is 6.89e-07.
