We divide 603905 by 85
The aim is to understand the frequency of 85 in 603905.

Moving on to step 1:
6 divided by 85 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 85

Moving on to step 2:
85 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 60 after subtracting 0 from 60.
Bring next digit (3) of the dividend behind the 60 and repeat the process: 603 / 85

Advancing to step 3:
The number 85 fits into 603 7 times, leaving a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 595 from 603 leaves us with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 85

Let's proceed to step 4:
If we divide 89 by 85, we get 1 and a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 71.0
If we take 85 away from 89, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 85

On to step 5:
The number 85 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 710.0
If we take 0 away from 40, we end up with 40.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 85

Moving on to step 6:
The number 85 fits into 405 4 times, leaving a remainder of 65.
Write down 4 as next digit of the result. 
Result so far: 7104.0
The remainder is 65 after subtracting 340 from 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 7:
If we divide 650 by 85, we get 7 and a remainder of 55.
Record the quotient 7 as the next digit in the result. 
Result so far: 7104.7
If we subtract 595 from 650, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 8:
When dividing 550 by 85, we get 6 with a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 7104.76
If we take 510 away from 550, we end up 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.

Going ahead to step 9:
85 goes into 400 4 times with a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 7104.764
The remainder is 60 after subtracting 340 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
85 can be fit into 600 7 times, resulting in a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 7104.7647
Subtracting 595 from 600 leaves us with 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 11:
When dividing 50 by 85, we get 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 7104.7647
The remainder is 50 after subtracting 0 from 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 12:
85 goes into 500 5 times with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 7104.764705
Subtract 425 from 500 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 13:
If we divide 750 by 85, we get 8 and a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 7104.7647058
Deduct 680 from 750 and we're left 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.

Let's proceed to step 14:
85 can be fit into 700 8 times, resulting in a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 7104.76470588
Deduct 680 from 700 and we're left 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.

In conclusion, the division gives 7104.76470588 with a balance of 2e-08.
