Let's divide 31159 by 85
The aim is to understand the frequency of 85 in 31159.

Going ahead to step 1:
85 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 85

Going ahead to step 2:
If we divide 31 by 85, we get 0 and a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Include the next digit (1) from the dividend after 31, then repeat: 311 / 85

Moving on to step 3:
85 goes into 311 3 times with a remainder of 56.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 255 away from 311, we end up with 56.
Include the next digit (5) from the dividend after 56, then repeat: 565 / 85

Advancing to step 4:
85 can be fit into 565 6 times, resulting in a remainder of 55.
Write down 6 as next digit of the result. 
Result so far: 36.0
Deduct 510 from 565 and we're left with 55.
Append the next digit (9) from the dividend to 55 and continue with: 559 / 85

Let's proceed to step 5:
When dividing 559 by 85, we get 6 with a remainder of 49.
Use 6 as the next digit of our solution. 
Result so far: 366.0
Subtract 510 from 559 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 6:
If we divide 490 by 85, we get 5 and a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 366.5
If we subtract 425 from 490, we 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.

Going ahead to step 7:
If we divide 650 by 85, we get 7 and a remainder of 55.
The number 7 becomes the next digit in our result. 
Result so far: 366.57
Subtracting 595 from 650 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 8:
If we divide 550 by 85, we get 6 and a remainder of 40.
The next digit of our result is 6. 
Result so far: 366.576
Subtracting 510 from 550 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
The number 85 fits into 400 4 times, leaving a remainder of 60.
Write down 4 as next digit of the result. 
Result so far: 366.5764
Subtracting 340 from 400 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
600 divided by 85 is 7 with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 366.57647
Subtract 595 from 600 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
If we divide 50 by 85, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 366.57647
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 12:
85 goes into 500 5 times with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 366.5764705
Subtract 425 from 500 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 13:
When dividing 750 by 85, we get 8 with a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 366.57647058
If we subtract 680 from 750, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 366.57647058 and a remainder of 7e-08.
