65596575 divided by 671 
The aim is to understand the frequency of 671 in 65596575.

On to step 1:
If we divide 6 by 671, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 671

Moving on to step 2:
When dividing 65 by 671, we get 0 with a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Grab the next digit (5) from the dividend, add it to 65, then carry on: 655 / 671

Let's proceed to step 3:
The number 671 fits into 655 0 times, leaving a remainder of 655.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 655 after subtracting 0 from 655.
Grab the next digit (9) from the dividend, add it to 655, then carry on: 6559 / 671

Let's proceed to step 4:
The number 671 fits into 6559 9 times, leaving a remainder of 520.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 520 after subtracting 6039 from 6559.
Include the next digit (6) from the dividend after 520, then repeat: 5206 / 671

Moving on to step 5:
The number 671 fits into 5206 7 times, leaving a remainder of 509.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
If we subtract 4697 from 5206, we get 509.
Take the next digit (5) from the dividend and append it to 509, then repeat: 5095 / 671

Advancing to step 6:
5095 divided by 671 is 7 with a remainder of 398.
Write down 7 as next digit of the result. 
Result so far: 977.0
Deduct 4697 from 5095 and we're left with 398.
Include the next digit (7) from the dividend after 398, then repeat: 3987 / 671

On to step 7:
671 goes into 3987 5 times with a remainder of 632.
Put 5 as the next digit of the answer. 
Result so far: 9775.0
If we subtract 3355 from 3987, we get 632.
Take the next digit (5) from the dividend and append it to 632, then repeat: 6325 / 671

Advancing to step 8:
When dividing 6325 by 671, we get 9 with a remainder of 286.
The number 9 becomes the next digit in our result. 
Result so far: 97759.0
Subtract 6039 from 6325 to get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Advancing to step 9:
671 goes into 2860 4 times with a remainder of 176.
Put 4 as the next digit of the answer. 
Result so far: 97759.4
The remainder is 176 after subtracting 2684 from 2860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 10:
671 can be fit into 1760 2 times, resulting in a remainder of 418.
Write down 2 as next digit of the result. 
Result so far: 97759.42
Subtracting 1342 from 1760 leaves us with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Step 11:
671 can be fit into 4180 6 times, resulting in a remainder of 154.
Put 6 as the next digit of the answer. 
Result so far: 97759.426
The remainder is 154 after subtracting 4026 from 4180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Step 12:
When dividing 1540 by 671, we get 2 with a remainder of 198.
Use 2 as the next digit of our solution. 
Result so far: 97759.4262
If we subtract 1342 from 1540, we get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Step 13:
671 can be fit into 1980 2 times, resulting in a remainder of 638.
The number 2 becomes the next digit in our result. 
Result so far: 97759.42622
If we take 1342 away from 1980, we end up with 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

The quotient of the division is 97759.42622, and the remainder is 0.000638.
