782570 divided by 85 
The aim is to understand the frequency of 85 in 782570.

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 take 0 away from 7, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 85

Step 2:
The number 85 fits into 78 0 times, leaving a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Append the next digit (2) from the dividend to 78 and continue with: 782 / 85

Step 3:
The number 85 fits into 782 9 times, leaving a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 765 from 782 and we're left with 17.
Grab the next digit (5) from the dividend, add it to 17, then carry on: 175 / 85

Advancing to step 4:
The number 85 fits into 175 2 times, leaving a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 92.0
If we take 170 away from 175, we end up with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 85

Advancing to step 5:
85 can be fit into 57 0 times, resulting in a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 920.0
If we take 0 away from 57, we end up with 57.
Take the next digit (0) from the dividend and append it to 57, then repeat: 570 / 85

Advancing to step 6:
570 divided by 85 is 6 with a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 9206.0
If we subtract 510 from 570, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 7:
The number 85 fits into 600 7 times, leaving a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 9206.7
The remainder is 5 after subtracting 595 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
50 divided by 85 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 9206.7
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.

Moving on to step 9:
The number 85 fits into 500 5 times, leaving a remainder of 75.
The next digit of our result is 5. 
Result so far: 9206.705
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 10:
85 can be fit into 750 8 times, resulting in a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 9206.7058
Deduct 680 from 750 and we're left 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.

Going ahead to step 11:
85 can be fit into 700 8 times, resulting in a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 9206.70588
Deduct 680 from 700 and we're left 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.

The quotient of the division is 9206.70588, and the remainder is 2e-05.
