We divide 898871 by 83
The aim is to understand the frequency of 83 in 898871.

Advancing to step 1:
If we divide 8 by 83, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 83

Moving on to step 2:
The number 83 fits into 89 1 times, leaving a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 6 after subtracting 83 from 89.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 83

Let's proceed to step 3:
When dividing 68 by 83, we get 0 with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 68, we end up with 68.
Fetch the next digit (8) from the dividend, attach it to 68 and continue: 688 / 83

Step 4:
83 can be fit into 688 8 times, resulting in a remainder of 24.
The next digit of our result is 8. 
Result so far: 108.0
If we subtract 664 from 688, we get 24.
Fetch the next digit (7) from the dividend, attach it to 24 and continue: 247 / 83

Moving on to step 5:
83 can be fit into 247 2 times, resulting in a remainder of 81.
The next digit of our result is 2. 
Result so far: 1082.0
The remainder is 81 after subtracting 166 from 247.
Bring next digit (1) of the dividend behind the 81 and repeat the process: 811 / 83

Going ahead to step 6:
83 can be fit into 811 9 times, resulting in a remainder of 64.
The number 9 becomes the next digit in our result. 
Result so far: 10829.0
Deduct 747 from 811 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 7:
The number 83 fits into 640 7 times, leaving a remainder of 59.
Write down 7 as next digit of the result. 
Result so far: 10829.7
If we subtract 581 from 640, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 8:
If we divide 590 by 83, we get 7 and a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 10829.77
Deduct 581 from 590 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final result is 10829.77 with a remainder of 0.009.
