290826 divided by 83 
The aim is to understand the frequency of 83 in 290826.

On to step 1:
2 divided by 83 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 83

Going ahead to step 2:
When dividing 29 by 83, we get 0 with a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 29 to get 29.
Fetch the next digit (0) from the dividend, attach it to 29 and continue: 290 / 83

Step 3:
The number 83 fits into 290 3 times, leaving a remainder of 41.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 249 from 290, we get 41.
Bring next digit (8) of the dividend behind the 41 and repeat the process: 418 / 83

Step 4:
When dividing 418 by 83, we get 5 with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Subtracting 415 from 418 leaves us with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 83

On to step 5:
When dividing 32 by 83, we get 0 with a remainder of 32.
Record the quotient 0 as the next digit in the result. 
Result so far: 350.0
The remainder is 32 after subtracting 0 from 32.
Take the next digit (6) from the dividend and append it to 32, then repeat: 326 / 83

Going ahead to step 6:
83 goes into 326 3 times with a remainder of 77.
The number 3 becomes the next digit in our result. 
Result so far: 3503.0
Subtract 249 from 326 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 7:
The number 83 fits into 770 9 times, leaving a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 3503.9
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.

Advancing to step 8:
When dividing 230 by 83, we get 2 with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 3503.92
The remainder is 64 after subtracting 166 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 9:
83 goes into 640 7 times with a remainder of 59.
Put 7 as the next digit of the answer. 
Result so far: 3503.927
Deduct 581 from 640 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 10:
If we divide 590 by 83, we get 7 and a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 3503.9277
If we subtract 581 from 590, we get 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 3503.9277 with a remainder of 9e-05.
