Let's divide 257864 by 85
The aim is to understand the frequency of 85 in 257864.

Advancing to step 1:
When dividing 2 by 85, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 85

On to step 2:
85 goes into 25 0 times with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Append the next digit (7) from the dividend to 25 and continue with: 257 / 85

On to step 3:
The number 85 fits into 257 3 times, leaving a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 255 from 257 and we're left with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 85

On to step 4:
The number 85 fits into 28 0 times, leaving a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Subtract 0 from 28 to get 28.
Append the next digit (6) from the dividend to 28 and continue with: 286 / 85

Step 5:
If we divide 286 by 85, we get 3 and a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 303.0
The remainder is 31 after subtracting 255 from 286.
Grab the next digit (4) from the dividend, add it to 31, then carry on: 314 / 85

Step 6:
When dividing 314 by 85, we get 3 with a remainder of 59.
Record the quotient 3 as the next digit in the result. 
Result so far: 3033.0
Subtracting 255 from 314 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 7:
If we divide 590 by 85, we get 6 and a remainder of 80.
Record the quotient 6 as the next digit in the result. 
Result so far: 3033.6
Subtracting 510 from 590 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 8:
If we divide 800 by 85, we get 9 and a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 3033.69
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.

Advancing to step 9:
When dividing 350 by 85, we get 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 3033.694
Subtract 340 from 350 to 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.

Advancing to step 10:
85 goes into 100 1 times with a remainder of 15.
The next digit of our result is 1. 
Result so far: 3033.6941
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.

Step 11:
The number 85 fits into 150 1 times, leaving a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 3033.69411
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.

The final result is 3033.69411 with a remainder of 6.5e-05.
