Let's divide 99657317 by 647
The aim is to understand the frequency of 647 in 99657317.

On to step 1:
647 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 647

Let's proceed to step 2:
647 can be fit into 99 0 times, resulting in a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Grab the next digit (6) from the dividend, add it to 99, then carry on: 996 / 647

Step 3:
If we divide 996 by 647, we get 1 and a remainder of 349.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 647 away from 996, we end up with 349.
Bring next digit (5) of the dividend behind the 349 and repeat the process: 3495 / 647

Going ahead to step 4:
If we divide 3495 by 647, we get 5 and a remainder of 260.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 3235 from 3495 leaves us with 260.
Append the next digit (7) from the dividend to 260 and continue with: 2607 / 647

Step 5:
The number 647 fits into 2607 4 times, leaving a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 154.0
Subtract 2588 from 2607 to get 19.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 647

Step 6:
647 goes into 193 0 times with a remainder of 193.
The number 0 becomes the next digit in our result. 
Result so far: 1540.0
Subtract 0 from 193 to get 193.
Take the next digit (1) from the dividend and append it to 193, then repeat: 1931 / 647

Step 7:
647 goes into 1931 2 times with a remainder of 637.
Record the quotient 2 as the next digit in the result. 
Result so far: 15402.0
Subtracting 1294 from 1931 leaves us with 637.
Grab the next digit (7) from the dividend, add it to 637, then carry on: 6377 / 647

Advancing to step 8:
When dividing 6377 by 647, we get 9 with a remainder of 554.
Put 9 as the next digit of the answer. 
Result so far: 154029.0
Subtracting 5823 from 6377 leaves us with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

On to step 9:
647 goes into 5540 8 times with a remainder of 364.
Write down 8 as next digit of the result. 
Result so far: 154029.8
The remainder is 364 after subtracting 5176 from 5540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Going ahead to step 10:
When dividing 3640 by 647, we get 5 with a remainder of 405.
The number 5 becomes the next digit in our result. 
Result so far: 154029.85
If we take 3235 away from 3640, we end up with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Step 11:
If we divide 4050 by 647, we get 6 and a remainder of 168.
The number 6 becomes the next digit in our result. 
Result so far: 154029.856
Subtracting 3882 from 4050 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 12:
647 goes into 1680 2 times with a remainder of 386.
Use 2 as the next digit of our solution. 
Result so far: 154029.8562
Subtract 1294 from 1680 to get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

On to step 13:
647 goes into 3860 5 times with a remainder of 625.
The number 5 becomes the next digit in our result. 
Result so far: 154029.85625
The remainder is 625 after subtracting 3235 from 3860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Let's proceed to step 14:
647 goes into 6250 9 times with a remainder of 427.
The number 9 becomes the next digit in our result. 
Result so far: 154029.856259
The remainder is 427 after subtracting 5823 from 6250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Moving on to step 15:
647 goes into 4270 6 times with a remainder of 388.
Use 6 as the next digit of our solution. 
Result so far: 154029.8562596
Deduct 3882 from 4270 and we're left with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

On to step 16:
3880 divided by 647 is 5 with a remainder of 645.
Write down 5 as next digit of the result. 
Result so far: 154029.85625965
Deduct 3235 from 3880 and we're left with 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

Our division results in 154029.85625965 with a remaining 6.45e-07.
