We're dividing 243625 by 85 
The aim is to understand the frequency of 85 in 243625.

Step 1:
2 divided by 85 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 85

Going ahead to step 2:
85 can be fit into 24 0 times, resulting in a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 24 leaves us with 24.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 85

Going ahead to step 3:
If we divide 243 by 85, we get 2 and a remainder of 73.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 73 after subtracting 170 from 243.
Grab the next digit (6) from the dividend, add it to 73, then carry on: 736 / 85

On to step 4:
If we divide 736 by 85, we get 8 and a remainder of 56.
The next digit of our result is 8. 
Result so far: 28.0
Subtract 680 from 736 to get 56.
Include the next digit (2) from the dividend after 56, then repeat: 562 / 85

Going ahead to step 5:
85 goes into 562 6 times with a remainder of 52.
The next digit of our result is 6. 
Result so far: 286.0
The remainder is 52 after subtracting 510 from 562.
Take the next digit (5) from the dividend and append it to 52, then repeat: 525 / 85

Step 6:
When dividing 525 by 85, we get 6 with a remainder of 15.
Put 6 as the next digit of the answer. 
Result so far: 2866.0
Subtracting 510 from 525 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.

Moving on to step 7:
The number 85 fits into 150 1 times, leaving a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 2866.1
Subtracting 85 from 150 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 8:
When dividing 650 by 85, we get 7 with a remainder of 55.
Record the quotient 7 as the next digit in the result. 
Result so far: 2866.17
If we take 595 away from 650, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 9:
When dividing 550 by 85, we get 6 with a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 2866.176
Deduct 510 from 550 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
400 divided by 85 is 4 with a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 2866.1764
The remainder is 60 after subtracting 340 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
85 goes into 600 7 times with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 2866.17647
Subtracting 595 from 600 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.

On to step 12:
When dividing 50 by 85, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 2866.17647
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.

Moving on to step 13:
When dividing 500 by 85, we get 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 2866.1764705
If we subtract 425 from 500, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 14:
The number 85 fits into 750 8 times, leaving a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 2866.17647058
The remainder is 70 after subtracting 680 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 2866.17647058 with a remainder of 7e-08.
