791691 ÷ 85 
The aim is to understand the frequency of 85 in 791691.

On to step 1:
The number 85 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 85

Let's proceed to step 2:
79 divided by 85 is 0 with a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Take the next digit (1) from the dividend and append it to 79, then repeat: 791 / 85

Let's proceed to step 3:
When dividing 791 by 85, we get 9 with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 765 from 791 leaves us with 26.
Append the next digit (6) from the dividend to 26 and continue with: 266 / 85

On to step 4:
85 can be fit into 266 3 times, resulting in a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
Deduct 255 from 266 and we're left with 11.
Include the next digit (9) from the dividend after 11, then repeat: 119 / 85

Moving on to step 5:
If we divide 119 by 85, we get 1 and a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 931.0
Subtract 85 from 119 to get 34.
Grab the next digit (1) from the dividend, add it to 34, then carry on: 341 / 85

On to step 6:
85 goes into 341 4 times with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 9314.0
Deduct 340 from 341 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
85 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 9314.0
Subtract 0 from 10 to 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.

Advancing to step 8:
85 goes into 100 1 times with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 9314.01
Deduct 85 from 100 and we're left 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.

Step 9:
If we divide 150 by 85, we get 1 and a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 9314.011
If we subtract 85 from 150, 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.

The quotient of the division is 9314.011, and the remainder is 0.0065.
