We look at the division of 6357620 by 85 
The aim is to understand the frequency of 85 in 6357620.

Let's proceed to step 1:
The number 85 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 85

Going ahead to step 2:
85 can be fit into 63 0 times, resulting in a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Append the next digit (5) from the dividend to 63 and continue with: 635 / 85

On to step 3:
85 goes into 635 7 times with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 595 from 635 leaves us with 40.
Fetch the next digit (7) from the dividend, attach it to 40 and continue: 407 / 85

On to step 4:
If we divide 407 by 85, we get 4 and a remainder of 67.
Write down 4 as next digit of the result. 
Result so far: 74.0
Subtracting 340 from 407 leaves us with 67.
Include the next digit (6) from the dividend after 67, then repeat: 676 / 85

Going ahead to step 5:
85 can be fit into 676 7 times, resulting in a remainder of 81.
Put 7 as the next digit of the answer. 
Result so far: 747.0
Subtract 595 from 676 to get 81.
Take the next digit (2) from the dividend and append it to 81, then repeat: 812 / 85

Moving on to step 6:
85 goes into 812 9 times with a remainder of 47.
Write down 9 as next digit of the result. 
Result so far: 7479.0
Deduct 765 from 812 and we're left with 47.
Fetch the next digit (0) from the dividend, attach it to 47 and continue: 470 / 85

On to step 7:
The number 85 fits into 470 5 times, leaving a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 74795.0
Deduct 425 from 470 and we're left with 45.
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 8:
If we divide 450 by 85, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 74795.5
Subtracting 425 from 450 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
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: 74795.52
If we take 170 away from 250, we end up 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.

Going ahead to step 10:
85 can be fit into 800 9 times, resulting in a remainder of 35.
The next digit of our result is 9. 
Result so far: 74795.529
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.

Moving on to step 11:
85 goes into 350 4 times with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 74795.5294
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.

Step 12:
85 can be fit into 100 1 times, resulting in a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 74795.52941
The remainder is 15 after subtracting 85 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 13:
150 divided by 85 is 1 with a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 74795.529411
Deduct 85 from 150 and we're left with 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 74795.529411, with a leftover of 6.5e-06.
