39573344 ÷ 85 
The aim is to understand the frequency of 85 in 39573344.

Step 1:
3 divided by 85 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 85

On to step 2:
The number 85 fits into 39 0 times, leaving a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 85

Let's proceed to step 3:
When dividing 395 by 85, we get 4 with a remainder of 55.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 340 from 395 leaves us with 55.
Append the next digit (7) from the dividend to 55 and continue with: 557 / 85

Step 4:
85 goes into 557 6 times with a remainder of 47.
Write down 6 as next digit of the result. 
Result so far: 46.0
Subtract 510 from 557 to get 47.
Grab the next digit (3) from the dividend, add it to 47, then carry on: 473 / 85

Let's proceed to step 5:
473 divided by 85 is 5 with a remainder of 48.
Write down 5 as next digit of the result. 
Result so far: 465.0
If we take 425 away from 473, we end up with 48.
Take the next digit (3) from the dividend and append it to 48, then repeat: 483 / 85

Going ahead to step 6:
483 divided by 85 is 5 with a remainder of 58.
The next digit of our result is 5. 
Result so far: 4655.0
The remainder is 58 after subtracting 425 from 483.
Include the next digit (4) from the dividend after 58, then repeat: 584 / 85

Going ahead to step 7:
85 goes into 584 6 times with a remainder of 74.
Use 6 as the next digit of our solution. 
Result so far: 46556.0
Subtracting 510 from 584 leaves us with 74.
Fetch the next digit (4) from the dividend, attach it to 74 and continue: 744 / 85

Going ahead to step 8:
If we divide 744 by 85, we get 8 and a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 465568.0
Subtract 680 from 744 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 9:
When dividing 640 by 85, we get 7 with a remainder of 45.
Put 7 as the next digit of the answer. 
Result so far: 465568.7
The remainder is 45 after subtracting 595 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 10:
85 goes into 450 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 465568.75
If we subtract 425 from 450, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 11:
85 can be fit into 250 2 times, resulting in a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 465568.752
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.

On to step 12:
If we divide 800 by 85, we get 9 and a remainder of 35.
The next digit of our result is 9. 
Result so far: 465568.7529
The remainder is 35 after subtracting 765 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 13:
350 divided by 85 is 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 465568.75294
Subtracting 340 from 350 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed 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: 465568.752941
Subtract 85 from 100 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 15:
85 can be fit into 150 1 times, resulting in a remainder of 65.
The next digit of our result is 1. 
Result so far: 465568.7529411
If we subtract 85 from 150, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final outcome is 465568.7529411, with a leftover of 6.5e-07.
