We look at the division of 35758948 by 817 
The aim is to understand the frequency of 817 in 35758948.

Step 1:
817 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 817

Step 2:
The number 817 fits into 35 0 times, leaving a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Take the next digit (7) from the dividend and append it to 35, then repeat: 357 / 817

Going ahead to step 3:
The number 817 fits into 357 0 times, leaving a remainder of 357.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 357 and we're left with 357.
Bring next digit (5) of the dividend behind the 357 and repeat the process: 3575 / 817

Advancing to step 4:
When dividing 3575 by 817, we get 4 with a remainder of 307.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 307 after subtracting 3268 from 3575.
Bring next digit (8) of the dividend behind the 307 and repeat the process: 3078 / 817

Step 5:
If we divide 3078 by 817, we get 3 and a remainder of 627.
Write down 3 as next digit of the result. 
Result so far: 43.0
Subtracting 2451 from 3078 leaves us with 627.
Fetch the next digit (9) from the dividend, attach it to 627 and continue: 6279 / 817

Advancing to step 6:
817 goes into 6279 7 times with a remainder of 560.
Record the quotient 7 as the next digit in the result. 
Result so far: 437.0
If we subtract 5719 from 6279, we get 560.
Grab the next digit (4) from the dividend, add it to 560, then carry on: 5604 / 817

Step 7:
5604 divided by 817 is 6 with a remainder of 702.
Write down 6 as next digit of the result. 
Result so far: 4376.0
Subtracting 4902 from 5604 leaves us with 702.
Grab the next digit (8) from the dividend, add it to 702, then carry on: 7028 / 817

Moving on to step 8:
When dividing 7028 by 817, we get 8 with a remainder of 492.
Write down 8 as next digit of the result. 
Result so far: 43768.0
If we subtract 6536 from 7028, we get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

On to step 9:
4920 divided by 817 is 6 with a remainder of 18.
The next digit of our result is 6. 
Result so far: 43768.6
The remainder is 18 after subtracting 4902 from 4920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 10:
If we divide 180 by 817, we get 0 and a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 43768.6
If we take 0 away from 180, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 11:
1800 divided by 817 is 2 with a remainder of 166.
The next digit of our result is 2. 
Result so far: 43768.602
Subtract 1634 from 1800 to get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

On to step 12:
817 can be fit into 1660 2 times, resulting in a remainder of 26.
The next digit of our result is 2. 
Result so far: 43768.6022
Subtract 1634 from 1660 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final outcome is 43768.6022, with a leftover of 0.00026.
