29285715 ÷ 647 
The aim is to understand the frequency of 647 in 29285715.

On to step 1:
When dividing 2 by 647, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 647

Going ahead to step 2:
If we divide 29 by 647, we get 0 and a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 29 after subtracting 0 from 29.
Grab the next digit (2) from the dividend, add it to 29, then carry on: 292 / 647

Step 3:
647 can be fit into 292 0 times, resulting in a remainder of 292.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 292 to get 292.
Grab the next digit (8) from the dividend, add it to 292, then carry on: 2928 / 647

Step 4:
647 goes into 2928 4 times with a remainder of 340.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 2588 from 2928, we get 340.
Fetch the next digit (5) from the dividend, attach it to 340 and continue: 3405 / 647

Let's proceed to step 5:
If we divide 3405 by 647, we get 5 and a remainder of 170.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtracting 3235 from 3405 leaves us with 170.
Append the next digit (7) from the dividend to 170 and continue with: 1707 / 647

Going ahead to step 6:
When dividing 1707 by 647, we get 2 with a remainder of 413.
The number 2 becomes the next digit in our result. 
Result so far: 452.0
If we subtract 1294 from 1707, we get 413.
Fetch the next digit (1) from the dividend, attach it to 413 and continue: 4131 / 647

Step 7:
When dividing 4131 by 647, we get 6 with a remainder of 249.
Put 6 as the next digit of the answer. 
Result so far: 4526.0
If we subtract 3882 from 4131, we get 249.
Include the next digit (5) from the dividend after 249, then repeat: 2495 / 647

Going ahead to step 8:
If we divide 2495 by 647, we get 3 and a remainder of 554.
Write down 3 as next digit of the result. 
Result so far: 45263.0
If we subtract 1941 from 2495, we get 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Let's proceed to step 9:
If we divide 5540 by 647, we get 8 and a remainder of 364.
Put 8 as the next digit of the answer. 
Result so far: 45263.8
Deduct 5176 from 5540 and we're left with 364.
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:
647 goes into 3640 5 times with a remainder of 405.
Use 5 as the next digit of our solution. 
Result so far: 45263.85
Subtracting 3235 from 3640 leaves us 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.

On to step 11:
647 goes into 4050 6 times with a remainder of 168.
Write down 6 as next digit of the result. 
Result so far: 45263.856
Subtract 3882 from 4050 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Let's proceed to step 12:
If we divide 1680 by 647, we get 2 and a remainder of 386.
Put 2 as the next digit of the answer. 
Result so far: 45263.8562
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.

Going ahead to step 13:
647 goes into 3860 5 times with a remainder of 625.
Use 5 as the next digit of our solution. 
Result so far: 45263.85625
If we subtract 3235 from 3860, we get 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Advancing to step 14:
6250 divided by 647 is 9 with a remainder of 427.
Record the quotient 9 as the next digit in the result. 
Result so far: 45263.856259
If we take 5823 away from 6250, we end up with 427.
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:
The number 647 fits into 4270 6 times, leaving a remainder of 388.
Use 6 as the next digit of our solution. 
Result so far: 45263.8562596
If we subtract 3882 from 4270, we get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Step 16:
The number 647 fits into 3880 5 times, leaving a remainder of 645.
Record the quotient 5 as the next digit in the result. 
Result so far: 45263.85625965
If we take 3235 away from 3880, we end up 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.

After the division, we end up with 45263.85625965 and a remainder of 6.45e-07.
