877520 ÷ 85 
The aim is to understand the frequency of 85 in 877520.

On to step 1:
If we divide 8 by 85, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 85

Step 2:
87 divided by 85 is 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 85 from 87 leaves us with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 85

Advancing to step 3:
85 goes into 27 0 times with a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 27 and we're left with 27.
Append the next digit (5) from the dividend to 27 and continue with: 275 / 85

Moving on to step 4:
The number 85 fits into 275 3 times, leaving a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 103.0
If we take 255 away from 275, we end up with 20.
Grab the next digit (2) from the dividend, add it to 20, then carry on: 202 / 85

Moving on to step 5:
When dividing 202 by 85, we get 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 1032.0
Subtract 170 from 202 to get 32.
Take the next digit (0) from the dividend and append it to 32, then repeat: 320 / 85

Advancing to step 6:
320 divided by 85 is 3 with a remainder of 65.
Use 3 as the next digit of our solution. 
Result so far: 10323.0
Subtract 255 from 320 to 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.

On to step 7:
If we divide 650 by 85, we get 7 and a remainder of 55.
Use 7 as the next digit of our solution. 
Result so far: 10323.7
If we take 595 away from 650, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 8:
When dividing 550 by 85, we get 6 with a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 10323.76
The remainder is 40 after subtracting 510 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
When dividing 400 by 85, we get 4 with a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 10323.764
If we subtract 340 from 400, 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 10:
600 divided by 85 is 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 10323.7647
If we take 595 away from 600, we end up 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.

On to step 11:
50 divided by 85 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 10323.7647
If we subtract 0 from 50, we 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.

Moving on to step 12:
85 goes into 500 5 times with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 10323.764705
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.

Moving on to step 13:
The number 85 fits into 750 8 times, leaving a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 10323.7647058
Subtract 680 from 750 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 14:
If we divide 700 by 85, we get 8 and a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 10323.76470588
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 final outcome is 10323.76470588, with a leftover of 2e-08.
