We're dividing 397007 by 85 
The aim is to understand the frequency of 85 in 397007.

Advancing to step 1:
85 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 85

Step 2:
When dividing 39 by 85, we get 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Append the next digit (7) from the dividend to 39 and continue with: 397 / 85

Advancing to step 3:
When dividing 397 by 85, we get 4 with a remainder of 57.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 340 from 397 leaves us with 57.
Append the next digit (0) from the dividend to 57 and continue with: 570 / 85

Advancing to step 4:
570 divided by 85 is 6 with a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 46.0
Subtracting 510 from 570 leaves us with 60.
Grab the next digit (0) from the dividend, add it to 60, then carry on: 600 / 85

On to step 5:
When dividing 600 by 85, we get 7 with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 467.0
Subtracting 595 from 600 leaves us with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 85

Going ahead to step 6:
The number 85 fits into 57 0 times, leaving a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 4670.0
If we take 0 away from 57, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 7:
85 goes into 570 6 times with a remainder of 60.
The next digit of our result is 6. 
Result so far: 4670.6
The remainder is 60 after subtracting 510 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 8:
85 goes into 600 7 times with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 4670.67
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.

Let's proceed to step 9:
50 divided by 85 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 4670.67
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.

Let's proceed to step 10:
500 divided by 85 is 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 4670.6705
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.

Moving on to step 11:
85 can be fit into 750 8 times, resulting in a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 4670.67058
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.

Advancing to step 12:
If we divide 700 by 85, we get 8 and a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 4670.670588
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.

Our division results in 4670.670588 with a remaining 2e-06.
