37617 ÷ 65 
The aim is to understand the frequency of 65 in 37617.

Going ahead to step 1:
When dividing 3 by 65, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 65

Going ahead to step 2:
When dividing 37 by 65, we get 0 with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Include the next digit (6) from the dividend after 37, then repeat: 376 / 65

Step 3:
If we divide 376 by 65, we get 5 and a remainder of 51.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 325 from 376 leaves us with 51.
Append the next digit (1) from the dividend to 51 and continue with: 511 / 65

Step 4:
The number 65 fits into 511 7 times, leaving a remainder of 56.
Use 7 as the next digit of our solution. 
Result so far: 57.0
Subtracting 455 from 511 leaves us with 56.
Bring next digit (7) of the dividend behind the 56 and repeat the process: 567 / 65

Advancing to step 5:
When dividing 567 by 65, we get 8 with a remainder of 47.
Record the quotient 8 as the next digit in the result. 
Result so far: 578.0
Deduct 520 from 567 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 6:
When dividing 470 by 65, we get 7 with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 578.7
Subtracting 455 from 470 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
If we divide 150 by 65, we get 2 and a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 578.72
If we take 130 away from 150, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
The number 65 fits into 200 3 times, leaving a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 578.723
Subtracting 195 from 200 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
65 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 578.723
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
65 goes into 500 7 times with a remainder of 45.
Put 7 as the next digit of the answer. 
Result so far: 578.72307
Subtracting 455 from 500 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 11:
65 goes into 450 6 times with a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 578.723076
Subtract 390 from 450 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 12:
The number 65 fits into 600 9 times, leaving a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 578.7230769
Subtracting 585 from 600 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 13:
If we divide 150 by 65, we get 2 and a remainder of 20.
The next digit of our result is 2. 
Result so far: 578.72307692
The remainder is 20 after subtracting 130 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 578.72307692, with a leftover of 2e-08.
