518308 ÷ 85 
The aim is to understand the frequency of 85 in 518308.

Moving on to step 1:
85 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 85

Advancing to step 2:
If we divide 51 by 85, we get 0 and a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Append the next digit (8) from the dividend to 51 and continue with: 518 / 85

Advancing to step 3:
If we divide 518 by 85, we get 6 and a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 510 from 518, we get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 85

Step 4:
85 goes into 83 0 times with a remainder of 83.
The next digit of our result is 0. 
Result so far: 60.0
If we take 0 away from 83, we end up with 83.
Take the next digit (0) from the dividend and append it to 83, then repeat: 830 / 85

Let's proceed to step 5:
85 goes into 830 9 times with a remainder of 65.
Write down 9 as next digit of the result. 
Result so far: 609.0
If we take 765 away from 830, we end up with 65.
Take the next digit (8) from the dividend and append it to 65, then repeat: 658 / 85

Step 6:
The number 85 fits into 658 7 times, leaving a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 6097.0
If we take 595 away from 658, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 7:
The number 85 fits into 630 7 times, leaving a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 6097.7
If we subtract 595 from 630, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 8:
The number 85 fits into 350 4 times, leaving a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 6097.74
If we take 340 away from 350, we end up 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 9:
If we divide 100 by 85, we get 1 and a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 6097.741
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.

Going ahead to step 10:
85 goes into 150 1 times with a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 6097.7411
Deduct 85 from 150 and we're left 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.

The final result is 6097.7411 with a remainder of 0.00065.
