991736 ÷ 83 
The aim is to understand the frequency of 83 in 991736.

Step 1:
The number 83 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 83

On to step 2:
If we divide 99 by 83, we get 1 and a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 83 from 99, we get 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 83

Advancing to step 3:
The number 83 fits into 161 1 times, leaving a remainder of 78.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtracting 83 from 161 leaves us with 78.
Include the next digit (7) from the dividend after 78, then repeat: 787 / 83

Moving on to step 4:
787 divided by 83 is 9 with a remainder of 40.
Write down 9 as next digit of the result. 
Result so far: 119.0
If we subtract 747 from 787, we get 40.
Take the next digit (3) from the dividend and append it to 40, then repeat: 403 / 83

Let's proceed to step 5:
If we divide 403 by 83, we get 4 and a remainder of 71.
Write down 4 as next digit of the result. 
Result so far: 1194.0
The remainder is 71 after subtracting 332 from 403.
Bring next digit (6) of the dividend behind the 71 and repeat the process: 716 / 83

Advancing to step 6:
When dividing 716 by 83, we get 8 with a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 11948.0
If we take 664 away from 716, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 7:
If we divide 520 by 83, we get 6 and a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 11948.6
If we subtract 498 from 520, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 8:
If we divide 220 by 83, we get 2 and a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 11948.62
Subtracting 166 from 220 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 9:
When dividing 540 by 83, we get 6 with a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 11948.626
Subtracting 498 from 540 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 10:
When dividing 420 by 83, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 11948.6265
Subtracting 415 from 420 leaves us 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 83 is 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 11948.6265
Subtract 0 from 50 to 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.

Let's proceed to step 12:
83 goes into 500 6 times with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 11948.626506
The remainder is 2 after subtracting 498 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
The number 83 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 11948.626506
Deduct 0 from 20 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.

On to step 14:
The number 83 fits into 200 2 times, leaving a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 11948.62650602
The remainder is 34 after subtracting 166 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 11948.62650602 and a remainder of 3.4e-08.
