615269 divided by 85 
The aim is to understand the frequency of 85 in 615269.

Moving 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
If we take 0 away from 6, we end up with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 85

Going ahead to step 2:
85 can be fit into 61 0 times, resulting in a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 61, we end up with 61.
Fetch the next digit (5) from the dividend, attach it to 61 and continue: 615 / 85

Step 3:
615 divided by 85 is 7 with a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 595 from 615, we get 20.
Take the next digit (2) from the dividend and append it to 20, then repeat: 202 / 85

Advancing to step 4:
85 goes into 202 2 times with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 72.0
Subtracting 170 from 202 leaves us with 32.
Append the next digit (6) from the dividend to 32 and continue with: 326 / 85

Step 5:
If we divide 326 by 85, we get 3 and a remainder of 71.
Use 3 as the next digit of our solution. 
Result so far: 723.0
The remainder is 71 after subtracting 255 from 326.
Grab the next digit (9) from the dividend, add it to 71, then carry on: 719 / 85

Going ahead to step 6:
85 can be fit into 719 8 times, resulting in a remainder of 39.
Put 8 as the next digit of the answer. 
Result so far: 7238.0
The remainder is 39 after subtracting 680 from 719.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 7:
85 goes into 390 4 times with a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 7238.4
If we take 340 away from 390, we end up 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.

Advancing to step 8:
85 goes into 500 5 times with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 7238.45
Deduct 425 from 500 and we're left 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.

Let's proceed to step 9:
If we divide 750 by 85, we get 8 and a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 7238.458
Subtracting 680 from 750 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
The number 85 fits into 700 8 times, leaving a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 7238.4588
If we take 680 away from 700, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 7238.4588 with a remainder of 0.0002.
