772166 ÷ 85 
The aim is to understand the frequency of 85 in 772166.

Going ahead to step 1:
If we divide 7 by 85, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 85

Moving on to step 2:
If we divide 77 by 85, we get 0 and a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Include the next digit (2) from the dividend after 77, then repeat: 772 / 85

Step 3:
85 can be fit into 772 9 times, resulting in a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 765 from 772 and we're left with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 85

On to step 4:
The number 85 fits into 71 0 times, leaving a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 90.0
Subtract 0 from 71 to get 71.
Include the next digit (6) from the dividend after 71, then repeat: 716 / 85

Going ahead to step 5:
85 goes into 716 8 times with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 908.0
If we subtract 680 from 716, we get 36.
Take the next digit (6) from the dividend and append it to 36, then repeat: 366 / 85

On to step 6:
The number 85 fits into 366 4 times, leaving a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 9084.0
If we take 340 away from 366, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 7:
The number 85 fits into 260 3 times, leaving a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 9084.3
Subtracting 255 from 260 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.

Moving on to step 8:
When dividing 50 by 85, we get 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 9084.3
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
85 goes into 500 5 times with a remainder of 75.
The next digit of our result is 5. 
Result so far: 9084.305
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.

Going ahead to step 10:
85 goes into 750 8 times with a remainder of 70.
The next digit of our result is 8. 
Result so far: 9084.3058
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.

On to step 11:
85 goes into 700 8 times with a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 9084.30588
Subtracting 680 from 700 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

In conclusion, the division gives 9084.30588 with a balance of 2e-05.
