Let's divide 78632554 by 817
The aim is to understand the frequency of 817 in 78632554.

Going ahead to step 1:
817 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 817

Moving on to step 2:
The number 817 fits into 78 0 times, leaving a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Append the next digit (6) from the dividend to 78 and continue with: 786 / 817

Moving on to step 3:
If we divide 786 by 817, we get 0 and a remainder of 786.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 786, we get 786.
Fetch the next digit (3) from the dividend, attach it to 786 and continue: 7863 / 817

Moving on to step 4:
7863 divided by 817 is 9 with a remainder of 510.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 510 after subtracting 7353 from 7863.
Append the next digit (2) from the dividend to 510 and continue with: 5102 / 817

Advancing to step 5:
If we divide 5102 by 817, we get 6 and a remainder of 200.
Use 6 as the next digit of our solution. 
Result so far: 96.0
The remainder is 200 after subtracting 4902 from 5102.
Fetch the next digit (5) from the dividend, attach it to 200 and continue: 2005 / 817

Advancing to step 6:
If we divide 2005 by 817, we get 2 and a remainder of 371.
The number 2 becomes the next digit in our result. 
Result so far: 962.0
The remainder is 371 after subtracting 1634 from 2005.
Grab the next digit (5) from the dividend, add it to 371, then carry on: 3715 / 817

Advancing to step 7:
3715 divided by 817 is 4 with a remainder of 447.
Put 4 as the next digit of the answer. 
Result so far: 9624.0
Subtract 3268 from 3715 to get 447.
Grab the next digit (4) from the dividend, add it to 447, then carry on: 4474 / 817

Advancing to step 8:
If we divide 4474 by 817, we get 5 and a remainder of 389.
Put 5 as the next digit of the answer. 
Result so far: 96245.0
If we subtract 4085 from 4474, we get 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Moving on to step 9:
If we divide 3890 by 817, we get 4 and a remainder of 622.
Record the quotient 4 as the next digit in the result. 
Result so far: 96245.4
If we take 3268 away from 3890, we end up with 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Going ahead to step 10:
If we divide 6220 by 817, we get 7 and a remainder of 501.
Put 7 as the next digit of the answer. 
Result so far: 96245.47
If we subtract 5719 from 6220, we get 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Moving on to step 11:
The number 817 fits into 5010 6 times, leaving a remainder of 108.
The number 6 becomes the next digit in our result. 
Result so far: 96245.476
If we take 4902 away from 5010, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 12:
The number 817 fits into 1080 1 times, leaving a remainder of 263.
The number 1 becomes the next digit in our result. 
Result so far: 96245.4761
If we subtract 817 from 1080, we get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Step 13:
The number 817 fits into 2630 3 times, leaving a remainder of 179.
Record the quotient 3 as the next digit in the result. 
Result so far: 96245.47613
Subtract 2451 from 2630 to get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Going ahead to step 14:
When dividing 1790 by 817, we get 2 with a remainder of 156.
Use 2 as the next digit of our solution. 
Result so far: 96245.476132
The remainder is 156 after subtracting 1634 from 1790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 15:
If we divide 1560 by 817, we get 1 and a remainder of 743.
Put 1 as the next digit of the answer. 
Result so far: 96245.4761321
Subtracting 817 from 1560 leaves us with 743.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7430, and continue the process.

Step 16:
817 goes into 7430 9 times with a remainder of 77.
Use 9 as the next digit of our solution. 
Result so far: 96245.47613219
Subtracting 7353 from 7430 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

The final outcome is 96245.47613219, with a leftover of 7.7e-08.
