Let's divide 312850 by 65
The aim is to understand the frequency of 65 in 312850.

Going ahead to step 1:
When dividing 3 by 65, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 65

On to step 2:
The number 65 fits into 31 0 times, leaving a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Grab the next digit (2) from the dividend, add it to 31, then carry on: 312 / 65

Step 3:
312 divided by 65 is 4 with a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 260 from 312 to get 52.
Fetch the next digit (8) from the dividend, attach it to 52 and continue: 528 / 65

Moving on to step 4:
65 goes into 528 8 times with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Deduct 520 from 528 and we're left with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 65

Moving on to step 5:
The number 65 fits into 85 1 times, leaving a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 481.0
Subtract 65 from 85 to get 20.
Take the next digit (0) from the dividend and append it to 20, then repeat: 200 / 65

On to step 6:
If we divide 200 by 65, we get 3 and a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 4813.0
Deduct 195 from 200 and we're left 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.

On to step 7:
If we divide 50 by 65, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 4813.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
65 goes into 500 7 times with a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 4813.07
Subtract 455 from 500 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 9:
When dividing 450 by 65, we get 6 with a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 4813.076
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.

Advancing to step 10:
If we divide 600 by 65, we get 9 and a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 4813.0769
If we take 585 away from 600, we end up 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.

Step 11:
150 divided by 65 is 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 4813.07692
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.

Step 12:
When dividing 200 by 65, we get 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 4813.076923
Subtract 195 from 200 to get 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 13:
The number 65 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 4813.076923
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 14:
65 can be fit into 500 7 times, resulting in a remainder of 45.
The next digit of our result is 7. 
Result so far: 4813.07692307
Subtract 455 from 500 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

After the division, we end up with 4813.07692307 and a remainder of 4.5e-08.
