12365912 divided by 85 
The aim is to understand the frequency of 85 in 12365912.

Moving on to step 1:
1 divided by 85 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 85

Step 2:
85 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 85

Advancing to step 3:
When dividing 123 by 85, we get 1 with a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 38 after subtracting 85 from 123.
Fetch the next digit (6) from the dividend, attach it to 38 and continue: 386 / 85

Let's proceed to step 4:
The number 85 fits into 386 4 times, leaving a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 340 away from 386, we end up with 46.
Grab the next digit (5) from the dividend, add it to 46, then carry on: 465 / 85

Advancing to step 5:
85 goes into 465 5 times with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 145.0
The remainder is 40 after subtracting 425 from 465.
Append the next digit (9) from the dividend to 40 and continue with: 409 / 85

Advancing to step 6:
85 can be fit into 409 4 times, resulting in a remainder of 69.
The number 4 becomes the next digit in our result. 
Result so far: 1454.0
Subtract 340 from 409 to get 69.
Take the next digit (1) from the dividend and append it to 69, then repeat: 691 / 85

On to step 7:
The number 85 fits into 691 8 times, leaving a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 14548.0
Subtract 680 from 691 to get 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 85

Step 8:
112 divided by 85 is 1 with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 145481.0
If we subtract 85 from 112, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 9:
85 can be fit into 270 3 times, resulting in a remainder of 15.
The next digit of our result is 3. 
Result so far: 145481.3
Subtract 255 from 270 to get 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 10:
85 goes into 150 1 times with a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 145481.31
Subtract 85 from 150 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 11:
85 goes into 650 7 times with a remainder of 55.
Write down 7 as next digit of the result. 
Result so far: 145481.317
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.

Going ahead to step 12:
When dividing 550 by 85, we get 6 with a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 145481.3176
Subtracting 510 from 550 leaves us 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 13:
85 can be fit into 400 4 times, resulting in a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 145481.31764
If we subtract 340 from 400, we 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 14:
When dividing 600 by 85, we get 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 145481.317647
If we subtract 595 from 600, we 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 15:
50 divided by 85 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 145481.317647
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.

Going ahead to step 16:
If we divide 500 by 85, we get 5 and a remainder of 75.
The next digit of our result is 5. 
Result so far: 145481.31764705
Subtracting 425 from 500 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The quotient of the division is 145481.31764705, and the remainder is 7.5e-08.
