778120 divided by 85 
The aim is to understand the frequency of 85 in 778120.

Advancing to step 1:
7 divided by 85 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 85

Going ahead to step 2:
77 divided by 85 is 0 with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Fetch the next digit (8) from the dividend, attach it to 77 and continue: 778 / 85

Advancing to step 3:
85 goes into 778 9 times with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 13 after subtracting 765 from 778.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 85

Moving on to step 4:
131 divided by 85 is 1 with a remainder of 46.
Use 1 as the next digit of our solution. 
Result so far: 91.0
Deduct 85 from 131 and we're left with 46.
Include the next digit (2) from the dividend after 46, then repeat: 462 / 85

Let's proceed to step 5:
The number 85 fits into 462 5 times, leaving a remainder of 37.
The number 5 becomes the next digit in our result. 
Result so far: 915.0
If we take 425 away from 462, we end up with 37.
Include the next digit (0) from the dividend after 37, then repeat: 370 / 85

Moving on to step 6:
85 goes into 370 4 times with a remainder of 30.
The next digit of our result is 4. 
Result so far: 9154.0
Subtract 340 from 370 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
When dividing 300 by 85, we get 3 with a remainder of 45.
Record the quotient 3 as the next digit in the result. 
Result so far: 9154.3
If we take 255 away from 300, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 8:
When dividing 450 by 85, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 9154.35
Subtracting 425 from 450 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
85 goes into 250 2 times with a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 9154.352
If we subtract 170 from 250, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 10:
The number 85 fits into 800 9 times, leaving a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 9154.3529
If we subtract 765 from 800, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 11:
85 goes into 350 4 times with a remainder of 10.
The next digit of our result is 4. 
Result so far: 9154.35294
The remainder is 10 after subtracting 340 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
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: 9154.352941
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.

Let's proceed to step 13:
The number 85 fits into 150 1 times, leaving a remainder of 65.
The next digit of our result is 1. 
Result so far: 9154.3529411
The remainder is 65 after subtracting 85 from 150.
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 9154.3529411, and the remainder is 6.5e-07.
