We divide 821289 by 83
The aim is to understand the frequency of 83 in 821289.

Going ahead to step 1:
When dividing 8 by 83, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 83

On to step 2:
83 goes into 82 0 times with a remainder of 82.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 82 leaves us with 82.
Fetch the next digit (1) from the dividend, attach it to 82 and continue: 821 / 83

Going ahead to step 3:
83 can be fit into 821 9 times, resulting in a remainder of 74.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 747 from 821, we get 74.
Append the next digit (2) from the dividend to 74 and continue with: 742 / 83

Step 4:
If we divide 742 by 83, we get 8 and a remainder of 78.
Use 8 as the next digit of our solution. 
Result so far: 98.0
If we take 664 away from 742, we end up with 78.
Bring next digit (8) of the dividend behind the 78 and repeat the process: 788 / 83

Step 5:
The number 83 fits into 788 9 times, leaving a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 989.0
If we subtract 747 from 788, we get 41.
Fetch the next digit (9) from the dividend, attach it to 41 and continue: 419 / 83

On to step 6:
The number 83 fits into 419 5 times, leaving a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 9895.0
The remainder is 4 after subtracting 415 from 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
When dividing 40 by 83, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 9895.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
83 can be fit into 400 4 times, resulting in a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 9895.04
Subtract 332 from 400 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 9:
If we divide 680 by 83, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 9895.048
If we subtract 664 from 680, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
If we divide 160 by 83, we get 1 and a remainder of 77.
The number 1 becomes the next digit in our result. 
Result so far: 9895.0481
Subtract 83 from 160 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 11:
83 goes into 770 9 times with a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 9895.04819
Subtract 747 from 770 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 12:
83 can be fit into 230 2 times, resulting in a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 9895.048192
If we subtract 166 from 230, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 13:
83 can be fit into 640 7 times, resulting in a remainder of 59.
Put 7 as the next digit of the answer. 
Result so far: 9895.0481927
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.

Going ahead to step 14:
When dividing 590 by 83, we get 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 9895.04819277
The remainder is 9 after subtracting 581 from 590.
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 outcome is 9895.04819277, with a leftover of 9e-09.
