39345966 divided by 817 
The aim is to understand the frequency of 817 in 39345966.

Moving on to step 1:
817 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 817

Advancing to step 2:
The number 817 fits into 39 0 times, leaving a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 817

Advancing to step 3:
If we divide 393 by 817, we get 0 and a remainder of 393.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 393, we end up with 393.
Grab the next digit (4) from the dividend, add it to 393, then carry on: 3934 / 817

Step 4:
When dividing 3934 by 817, we get 4 with a remainder of 666.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 3268 from 3934 and we're left with 666.
Include the next digit (5) from the dividend after 666, then repeat: 6665 / 817

Let's proceed to step 5:
6665 divided by 817 is 8 with a remainder of 129.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
If we take 6536 away from 6665, we end up with 129.
Include the next digit (9) from the dividend after 129, then repeat: 1299 / 817

Advancing to step 6:
1299 divided by 817 is 1 with a remainder of 482.
Write down 1 as next digit of the result. 
Result so far: 481.0
Subtract 817 from 1299 to get 482.
Fetch the next digit (6) from the dividend, attach it to 482 and continue: 4826 / 817

Let's proceed to step 7:
If we divide 4826 by 817, we get 5 and a remainder of 741.
Use 5 as the next digit of our solution. 
Result so far: 4815.0
If we take 4085 away from 4826, we end up with 741.
Grab the next digit (6) from the dividend, add it to 741, then carry on: 7416 / 817

Moving on to step 8:
If we divide 7416 by 817, we get 9 and a remainder of 63.
The next digit of our result is 9. 
Result so far: 48159.0
If we take 7353 away from 7416, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 9:
The number 817 fits into 630 0 times, leaving a remainder of 630.
Write down 0 as next digit of the result. 
Result so far: 48159.0
Subtract 0 from 630 to get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Advancing to step 10:
817 goes into 6300 7 times with a remainder of 581.
Write down 7 as next digit of the result. 
Result so far: 48159.07
Subtract 5719 from 6300 to get 581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

On to step 11:
The number 817 fits into 5810 7 times, leaving a remainder of 91.
The number 7 becomes the next digit in our result. 
Result so far: 48159.077
Subtract 5719 from 5810 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

After the division, we end up with 48159.077 and a remainder of 0.0091.
