25117953 ÷ 85 
The aim is to understand the frequency of 85 in 25117953.

Let's proceed to step 1:
85 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 85

Moving on to step 2:
25 divided by 85 is 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Take the next digit (1) from the dividend and append it to 25, then repeat: 251 / 85

Step 3:
251 divided by 85 is 2 with a remainder of 81.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 81 after subtracting 170 from 251.
Take the next digit (1) from the dividend and append it to 81, then repeat: 811 / 85

Going ahead to step 4:
When dividing 811 by 85, we get 9 with a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtract 765 from 811 to get 46.
Grab the next digit (7) from the dividend, add it to 46, then carry on: 467 / 85

Advancing to step 5:
If we divide 467 by 85, we get 5 and a remainder of 42.
Put 5 as the next digit of the answer. 
Result so far: 295.0
If we subtract 425 from 467, we get 42.
Append the next digit (9) from the dividend to 42 and continue with: 429 / 85

On to step 6:
If we divide 429 by 85, we get 5 and a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 2955.0
If we subtract 425 from 429, we get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 85

Let's proceed to step 7:
45 divided by 85 is 0 with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 29550.0
Subtracting 0 from 45 leaves us with 45.
Bring next digit (3) of the dividend behind the 45 and repeat the process: 453 / 85

Going ahead to step 8:
If we divide 453 by 85, we get 5 and a remainder of 28.
Use 5 as the next digit of our solution. 
Result so far: 295505.0
If we subtract 425 from 453, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
If we divide 280 by 85, we get 3 and a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 295505.3
Subtracting 255 from 280 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.

Moving on to step 10:
When dividing 250 by 85, we get 2 with a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 295505.32
Subtract 170 from 250 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 11:
The number 85 fits into 800 9 times, leaving a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 295505.329
Deduct 765 from 800 and we're left with 35.
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 12:
The number 85 fits into 350 4 times, leaving a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 295505.3294
If we take 340 away from 350, we end up 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.

On to step 13:
85 can be fit into 100 1 times, resulting in a remainder of 15.
The next digit of our result is 1. 
Result so far: 295505.32941
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 14:
85 goes into 150 1 times with a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 295505.329411
Subtract 85 from 150 to 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.

Our division results in 295505.329411 with a remaining 6.5e-06.
