We divide 640092 by 85
The aim is to understand the frequency of 85 in 640092.

On to step 1:
6 divided by 85 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 85

On to step 2:
85 goes into 64 0 times with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Take the next digit (0) from the dividend and append it to 64, then repeat: 640 / 85

Moving on to step 3:
If we divide 640 by 85, we get 7 and a remainder of 45.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 595 from 640, we get 45.
Grab the next digit (0) from the dividend, add it to 45, then carry on: 450 / 85

Step 4:
85 can be fit into 450 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 75.0
Deduct 425 from 450 and we're left with 25.
Fetch the next digit (9) from the dividend, attach it to 25 and continue: 259 / 85

Going ahead to step 5:
85 goes into 259 3 times with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 753.0
Subtracting 255 from 259 leaves us with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 85

Step 6:
When dividing 42 by 85, we get 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 7530.0
If we subtract 0 from 42, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 7:
The number 85 fits into 420 4 times, leaving a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 7530.4
If we take 340 away from 420, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 8:
If we divide 800 by 85, we get 9 and a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 7530.49
Deduct 765 from 800 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 9:
350 divided by 85 is 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 7530.494
Deduct 340 from 350 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
The number 85 fits into 100 1 times, leaving a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 7530.4941
Subtract 85 from 100 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.

Step 11:
The number 85 fits into 150 1 times, leaving a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 7530.49411
The remainder is 65 after subtracting 85 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final result is 7530.49411 with a remainder of 6.5e-05.
