853480 divided by 85 
The aim is to understand the frequency of 85 in 853480.

Advancing to step 1:
If we divide 8 by 85, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 85

Let's proceed to step 2:
If we divide 85 by 85, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 0 after subtracting 85 from 85.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 85

Advancing to step 3:
85 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 85

On to step 4:
85 can be fit into 34 0 times, resulting in a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 100.0
Deduct 0 from 34 and we're left with 34.
Grab the next digit (8) from the dividend, add it to 34, then carry on: 348 / 85

Going ahead to step 5:
85 goes into 348 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 1004.0
Deduct 340 from 348 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 85

Advancing to step 6:
If we divide 80 by 85, we get 0 and a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 10040.0
The remainder is 80 after subtracting 0 from 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 7:
If we divide 800 by 85, we get 9 and a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 10040.9
Subtract 765 from 800 to get 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 8:
When dividing 350 by 85, we get 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 10040.94
Deduct 340 from 350 and we're left 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 9:
85 can be fit into 100 1 times, resulting in a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 10040.941
If we take 85 away from 100, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 10:
The number 85 fits into 150 1 times, leaving a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 10040.9411
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 quotient of the division is 10040.9411, and the remainder is 0.00065.
