We're dividing 77335869 by 817 
The aim is to understand the frequency of 817 in 77335869.

Advancing to step 1:
817 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 817

Advancing to step 2:
817 goes into 77 0 times with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Bring next digit (3) of the dividend behind the 77 and repeat the process: 773 / 817

Moving on to step 3:
If we divide 773 by 817, we get 0 and a remainder of 773.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 773, we get 773.
Grab the next digit (3) from the dividend, add it to 773, then carry on: 7733 / 817

Advancing to step 4:
817 can be fit into 7733 9 times, resulting in a remainder of 380.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 380 after subtracting 7353 from 7733.
Include the next digit (5) from the dividend after 380, then repeat: 3805 / 817

Let's proceed to step 5:
3805 divided by 817 is 4 with a remainder of 537.
Use 4 as the next digit of our solution. 
Result so far: 94.0
If we subtract 3268 from 3805, we get 537.
Take the next digit (8) from the dividend and append it to 537, then repeat: 5378 / 817

Advancing to step 6:
5378 divided by 817 is 6 with a remainder of 476.
Record the quotient 6 as the next digit in the result. 
Result so far: 946.0
If we take 4902 away from 5378, we end up with 476.
Append the next digit (6) from the dividend to 476 and continue with: 4766 / 817

On to step 7:
4766 divided by 817 is 5 with a remainder of 681.
The number 5 becomes the next digit in our result. 
Result so far: 9465.0
Deduct 4085 from 4766 and we're left with 681.
Append the next digit (9) from the dividend to 681 and continue with: 6819 / 817

Let's proceed to step 8:
If we divide 6819 by 817, we get 8 and a remainder of 283.
Record the quotient 8 as the next digit in the result. 
Result so far: 94658.0
Subtracting 6536 from 6819 leaves us with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Advancing to step 9:
The number 817 fits into 2830 3 times, leaving a remainder of 379.
Write down 3 as next digit of the result. 
Result so far: 94658.3
Deduct 2451 from 2830 and we're left with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Advancing to step 10:
817 can be fit into 3790 4 times, resulting in a remainder of 522.
The next digit of our result is 4. 
Result so far: 94658.34
Subtract 3268 from 3790 to get 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Step 11:
When dividing 5220 by 817, we get 6 with a remainder of 318.
The next digit of our result is 6. 
Result so far: 94658.346
Subtracting 4902 from 5220 leaves us with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Step 12:
3180 divided by 817 is 3 with a remainder of 729.
Put 3 as the next digit of the answer. 
Result so far: 94658.3463
Subtract 2451 from 3180 to get 729.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7290, and continue the process.

Moving on to step 13:
The number 817 fits into 7290 8 times, leaving a remainder of 754.
Record the quotient 8 as the next digit in the result. 
Result so far: 94658.34638
Subtracting 6536 from 7290 leaves us with 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

On to step 14:
817 can be fit into 7540 9 times, resulting in a remainder of 187.
Record the quotient 9 as the next digit in the result. 
Result so far: 94658.346389
Deduct 7353 from 7540 and we're left with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Advancing to step 15:
The number 817 fits into 1870 2 times, leaving a remainder of 236.
The next digit of our result is 2. 
Result so far: 94658.3463892
Subtracting 1634 from 1870 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Moving on to step 16:
The number 817 fits into 2360 2 times, leaving a remainder of 726.
The number 2 becomes the next digit in our result. 
Result so far: 94658.34638922
If we subtract 1634 from 2360, we get 726.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

The quotient of the division is 94658.34638922, and the remainder is 7.26e-07.
