We look at the division of 57511366 by 647 
The aim is to understand the frequency of 647 in 57511366.

Let's proceed to step 1:
647 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 647

Going ahead to step 2:
647 goes into 57 0 times with a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Fetch the next digit (5) from the dividend, attach it to 57 and continue: 575 / 647

Step 3:
The number 647 fits into 575 0 times, leaving a remainder of 575.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 575 leaves us with 575.
Bring next digit (1) of the dividend behind the 575 and repeat the process: 5751 / 647

Let's proceed to step 4:
If we divide 5751 by 647, we get 8 and a remainder of 575.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 5176 from 5751 and we're left with 575.
Include the next digit (1) from the dividend after 575, then repeat: 5751 / 647

Step 5:
When dividing 5751 by 647, we get 8 with a remainder of 575.
The next digit of our result is 8. 
Result so far: 88.0
If we subtract 5176 from 5751, we get 575.
Fetch the next digit (3) from the dividend, attach it to 575 and continue: 5753 / 647

Advancing to step 6:
647 goes into 5753 8 times with a remainder of 577.
The number 8 becomes the next digit in our result. 
Result so far: 888.0
Subtracting 5176 from 5753 leaves us with 577.
Take the next digit (6) from the dividend and append it to 577, then repeat: 5776 / 647

Going ahead to step 7:
647 can be fit into 5776 8 times, resulting in a remainder of 600.
Put 8 as the next digit of the answer. 
Result so far: 8888.0
Subtract 5176 from 5776 to get 600.
Take the next digit (6) from the dividend and append it to 600, then repeat: 6006 / 647

Moving on to step 8:
If we divide 6006 by 647, we get 9 and a remainder of 183.
The number 9 becomes the next digit in our result. 
Result so far: 88889.0
If we subtract 5823 from 6006, we get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Step 9:
If we divide 1830 by 647, we get 2 and a remainder of 536.
Put 2 as the next digit of the answer. 
Result so far: 88889.2
If we subtract 1294 from 1830, we get 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Let's proceed to step 10:
647 goes into 5360 8 times with a remainder of 184.
The number 8 becomes the next digit in our result. 
Result so far: 88889.28
If we subtract 5176 from 5360, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 11:
1840 divided by 647 is 2 with a remainder of 546.
Record the quotient 2 as the next digit in the result. 
Result so far: 88889.282
Subtracting 1294 from 1840 leaves us with 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Moving on to step 12:
The number 647 fits into 5460 8 times, leaving a remainder of 284.
The next digit of our result is 8. 
Result so far: 88889.2828
If we subtract 5176 from 5460, we get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 13:
The number 647 fits into 2840 4 times, leaving a remainder of 252.
The next digit of our result is 4. 
Result so far: 88889.28284
If we take 2588 away from 2840, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 14:
647 goes into 2520 3 times with a remainder of 579.
The number 3 becomes the next digit in our result. 
Result so far: 88889.282843
The remainder is 579 after subtracting 1941 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

On to step 15:
647 goes into 5790 8 times with a remainder of 614.
The next digit of our result is 8. 
Result so far: 88889.2828438
If we subtract 5176 from 5790, we get 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Going ahead to step 16:
647 can be fit into 6140 9 times, resulting in a remainder of 317.
Put 9 as the next digit of the answer. 
Result so far: 88889.28284389
Deduct 5823 from 6140 and we're left with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

In conclusion, the division gives 88889.28284389 with a balance of 3.17e-07.
