910821 divided by 85 
The aim is to understand the frequency of 85 in 910821.

Let's proceed to step 1:
85 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 85

Moving on to step 2:
The number 85 fits into 91 1 times, leaving a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 85 from 91 leaves us with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 85

Going ahead to step 3:
60 divided by 85 is 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 60 after subtracting 0 from 60.
Append the next digit (8) from the dividend to 60 and continue with: 608 / 85

Step 4:
The number 85 fits into 608 7 times, leaving a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 107.0
Subtract 595 from 608 to get 13.
Include the next digit (2) from the dividend after 13, then repeat: 132 / 85

Let's proceed to step 5:
85 goes into 132 1 times with a remainder of 47.
Put 1 as the next digit of the answer. 
Result so far: 1071.0
Deduct 85 from 132 and we're left with 47.
Take the next digit (1) from the dividend and append it to 47, then repeat: 471 / 85

Advancing to step 6:
The number 85 fits into 471 5 times, leaving a remainder of 46.
Record the quotient 5 as the next digit in the result. 
Result so far: 10715.0
Subtract 425 from 471 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 7:
If we divide 460 by 85, we get 5 and a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 10715.5
Subtract 425 from 460 to 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.

Moving on to step 8:
If we divide 350 by 85, we get 4 and a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 10715.54
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.

Advancing to step 9:
85 can be fit into 100 1 times, resulting in a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 10715.541
Subtract 85 from 100 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
85 can be fit into 150 1 times, resulting in a remainder of 65.
The next digit of our result is 1. 
Result so far: 10715.5411
Subtracting 85 from 150 leaves us with 65.
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 10715.5411, and the remainder is 0.00065.
