We look at the division of 115830 by 85 
The aim is to understand the frequency of 85 in 115830.

Moving on to step 1:
If we divide 1 by 85, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 85

Advancing to step 2:
85 goes into 11 0 times with a remainder of 11.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 85

On to step 3:
85 can be fit into 115 1 times, resulting in a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 85 away from 115, we end up with 30.
Fetch the next digit (8) from the dividend, attach it to 30 and continue: 308 / 85

On to step 4:
308 divided by 85 is 3 with a remainder of 53.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 53 after subtracting 255 from 308.
Grab the next digit (3) from the dividend, add it to 53, then carry on: 533 / 85

Step 5:
533 divided by 85 is 6 with a remainder of 23.
The next digit of our result is 6. 
Result so far: 136.0
If we subtract 510 from 533, we get 23.
Bring next digit (0) of the dividend behind the 23 and repeat the process: 230 / 85

On to step 6:
If we divide 230 by 85, we get 2 and a remainder of 60.
Put 2 as the next digit of the answer. 
Result so far: 1362.0
Deduct 170 from 230 and we're left 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.

Advancing to step 7:
85 goes into 600 7 times with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 1362.7
Subtracting 595 from 600 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
50 divided by 85 is 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 1362.7
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
The number 85 fits into 500 5 times, leaving a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 1362.705
If we take 425 away from 500, we end up with 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 10:
The number 85 fits into 750 8 times, leaving a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 1362.7058
Subtracting 680 from 750 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.

Advancing to step 11:
700 divided by 85 is 8 with a remainder of 20.
The next digit of our result is 8. 
Result so far: 1362.70588
If we subtract 680 from 700, we 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.

The quotient of the division is 1362.70588, and the remainder is 2e-05.
