We're dividing 45397 by 85 
The aim is to understand the frequency of 85 in 45397.

Moving on to step 1:
85 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 85

Let's proceed to step 2:
45 divided by 85 is 0 with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Fetch the next digit (3) from the dividend, attach it to 45 and continue: 453 / 85

Going ahead to step 3:
When dividing 453 by 85, we get 5 with a remainder of 28.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 425 from 453, we get 28.
Fetch the next digit (9) from the dividend, attach it to 28 and continue: 289 / 85

Going ahead to step 4:
When dividing 289 by 85, we get 3 with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 53.0
Deduct 255 from 289 and we're left with 34.
Grab the next digit (7) from the dividend, add it to 34, then carry on: 347 / 85

Let's proceed to step 5:
347 divided by 85 is 4 with a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 534.0
Subtract 340 from 347 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 6:
70 divided by 85 is 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 534.0
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 7:
700 divided by 85 is 8 with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 534.08
Subtract 680 from 700 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
The number 85 fits into 200 2 times, leaving a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 534.082
Subtract 170 from 200 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
The number 85 fits into 300 3 times, leaving a remainder of 45.
Put 3 as the next digit of the answer. 
Result so far: 534.0823
If we subtract 255 from 300, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 10:
If we divide 450 by 85, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 534.08235
Subtract 425 from 450 to 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.

Step 11:
When dividing 250 by 85, we get 2 with a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 534.082352
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 12:
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: 534.0823529
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.

Moving on to step 13:
When dividing 350 by 85, we get 4 with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 534.08235294
If we subtract 340 from 350, we 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.

The final result is 534.08235294 with a remainder of 1e-08.
