478948 divided by 85 
The aim is to understand the frequency of 85 in 478948.

On to step 1:
85 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 85

On to step 2:
85 goes into 47 0 times with a remainder of 47.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 47, we end up with 47.
Grab the next digit (8) from the dividend, add it to 47, then carry on: 478 / 85

Advancing to step 3:
When dividing 478 by 85, we get 5 with a remainder of 53.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 425 from 478 leaves us with 53.
Grab the next digit (9) from the dividend, add it to 53, then carry on: 539 / 85

On to step 4:
If we divide 539 by 85, we get 6 and a remainder of 29.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
The remainder is 29 after subtracting 510 from 539.
Take the next digit (4) from the dividend and append it to 29, then repeat: 294 / 85

On to step 5:
294 divided by 85 is 3 with a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 563.0
If we subtract 255 from 294, we get 39.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 85

Going ahead to step 6:
When dividing 398 by 85, we get 4 with a remainder of 58.
Put 4 as the next digit of the answer. 
Result so far: 5634.0
If we subtract 340 from 398, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 7:
When dividing 580 by 85, we get 6 with a remainder of 70.
Use 6 as the next digit of our solution. 
Result so far: 5634.6
If we take 510 away from 580, we end up 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.

Going ahead to step 8:
85 goes into 700 8 times with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 5634.68
Subtracting 680 from 700 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
85 can be fit into 200 2 times, resulting in a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 5634.682
If we take 170 away from 200, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
300 divided by 85 is 3 with a remainder of 45.
Use 3 as the next digit of our solution. 
Result so far: 5634.6823
The remainder is 45 after subtracting 255 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 11:
85 goes into 450 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 5634.68235
If we take 425 away from 450, we end up 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.

On to step 12:
85 goes into 250 2 times with a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 5634.682352
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.

Advancing to step 13:
When dividing 800 by 85, we get 9 with a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 5634.6823529
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.

Step 14:
85 can be fit into 350 4 times, resulting in a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 5634.68235294
The remainder is 10 after subtracting 340 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 5634.68235294 with a remaining 1e-08.
