671097 ÷ 85 
The aim is to understand the frequency of 85 in 671097.

On to step 1:
6 divided by 85 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 85

Going ahead to step 2:
85 can be fit into 67 0 times, resulting in a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Take the next digit (1) from the dividend and append it to 67, then repeat: 671 / 85

Step 3:
85 goes into 671 7 times with a remainder of 76.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 76 after subtracting 595 from 671.
Bring next digit (0) of the dividend behind the 76 and repeat the process: 760 / 85

Advancing to step 4:
85 can be fit into 760 8 times, resulting in a remainder of 80.
The next digit of our result is 8. 
Result so far: 78.0
Subtract 680 from 760 to get 80.
Bring next digit (9) of the dividend behind the 80 and repeat the process: 809 / 85

On to step 5:
85 goes into 809 9 times with a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 789.0
Subtracting 765 from 809 leaves us with 44.
Take the next digit (7) from the dividend and append it to 44, then repeat: 447 / 85

On to step 6:
85 can be fit into 447 5 times, resulting in a remainder of 22.
Put 5 as the next digit of the answer. 
Result so far: 7895.0
If we subtract 425 from 447, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
The number 85 fits into 220 2 times, leaving a remainder of 50.
Put 2 as the next digit of the answer. 
Result so far: 7895.2
The remainder is 50 after subtracting 170 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
500 divided by 85 is 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 7895.25
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.

Advancing to step 9:
85 can be fit into 750 8 times, resulting in a remainder of 70.
Record the quotient 8 as the next digit in the result. 
Result so far: 7895.258
If we take 680 away from 750, 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.

Moving on to step 10:
When dividing 700 by 85, we get 8 with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 7895.2588
Subtract 680 from 700 to 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 7895.2588, and the remainder is 0.0002.
