We're dividing 603893 by 85 
The aim is to understand the frequency of 85 in 603893.

Advancing to step 1:
If we divide 6 by 85, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 85

On to step 2:
60 divided by 85 is 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 60, we get 60.
Append the next digit (3) from the dividend to 60 and continue with: 603 / 85

Going ahead to step 3:
603 divided by 85 is 7 with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 8 after subtracting 595 from 603.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 85

On to step 4:
85 can be fit into 88 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 71.0
If we take 85 away from 88, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 85

Going ahead to step 5:
39 divided by 85 is 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 710.0
Deduct 0 from 39 and we're left with 39.
Append the next digit (3) from the dividend to 39 and continue with: 393 / 85

Going ahead to step 6:
393 divided by 85 is 4 with a remainder of 53.
Put 4 as the next digit of the answer. 
Result so far: 7104.0
If we take 340 away from 393, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 7:
85 goes into 530 6 times with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 7104.6
If we take 510 away from 530, 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.

Moving on to step 8:
200 divided by 85 is 2 with a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 7104.62
Subtract 170 from 200 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
The number 85 fits into 300 3 times, leaving a remainder of 45.
Record the quotient 3 as the next digit in the result. 
Result so far: 7104.623
The remainder is 45 after subtracting 255 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 10:
The number 85 fits into 450 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 7104.6235
The remainder is 25 after subtracting 425 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 11:
250 divided by 85 is 2 with a remainder of 80.
The next digit of our result is 2. 
Result so far: 7104.62352
Subtracting 170 from 250 leaves us 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.

Advancing to step 12:
85 can be fit into 800 9 times, resulting in a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 7104.623529
If we subtract 765 from 800, 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.

Step 13:
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: 7104.6235294
If we subtract 340 from 350, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 14:
100 divided by 85 is 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 7104.62352941
Subtracting 85 from 100 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 7104.62352941, and the remainder is 1.5e-08.
