We divide 7584515 by 85
The aim is to understand the frequency of 85 in 7584515.

Going ahead to step 1:
The number 85 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 85

Advancing to step 2:
If we divide 75 by 85, we get 0 and a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Grab the next digit (8) from the dividend, add it to 75, then carry on: 758 / 85

Moving on to step 3:
758 divided by 85 is 8 with a remainder of 78.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 680 from 758 and we're left with 78.
Bring next digit (4) of the dividend behind the 78 and repeat the process: 784 / 85

Moving on to step 4:
The number 85 fits into 784 9 times, leaving a remainder of 19.
The next digit of our result is 9. 
Result so far: 89.0
Subtract 765 from 784 to get 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 85

Advancing to step 5:
If we divide 195 by 85, we get 2 and a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 892.0
The remainder is 25 after subtracting 170 from 195.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 85

Step 6:
When dividing 251 by 85, we get 2 with a remainder of 81.
Write down 2 as next digit of the result. 
Result so far: 8922.0
Subtract 170 from 251 to get 81.
Bring next digit (5) of the dividend behind the 81 and repeat the process: 815 / 85

On to step 7:
85 can be fit into 815 9 times, resulting in a remainder of 50.
Use 9 as the next digit of our solution. 
Result so far: 89229.0
Subtract 765 from 815 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.

Moving on to step 8:
If we divide 500 by 85, we get 5 and a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 89229.5
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.

Going ahead to step 9:
If we divide 750 by 85, we get 8 and a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 89229.58
Subtract 680 from 750 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 10:
If we divide 700 by 85, we get 8 and a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 89229.588
Subtracting 680 from 700 leaves us 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.

Our division results in 89229.588 with a remaining 0.002.
