691491 ÷ 83 
The aim is to understand the frequency of 83 in 691491.

Step 1:
83 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 83

Advancing to step 2:
83 goes into 69 0 times with a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 69 after subtracting 0 from 69.
Fetch the next digit (1) from the dividend, attach it to 69 and continue: 691 / 83

Let's proceed to step 3:
691 divided by 83 is 8 with a remainder of 27.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 664 from 691 and we're left with 27.
Fetch the next digit (4) from the dividend, attach it to 27 and continue: 274 / 83

On to step 4:
If we divide 274 by 83, we get 3 and a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
Subtracting 249 from 274 leaves us with 25.
Bring next digit (9) of the dividend behind the 25 and repeat the process: 259 / 83

Let's proceed to step 5:
83 goes into 259 3 times with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 833.0
If we take 249 away from 259, we end up with 10.
Fetch the next digit (1) from the dividend, attach it to 10 and continue: 101 / 83

Step 6:
If we divide 101 by 83, we get 1 and a remainder of 18.
The next digit of our result is 1. 
Result so far: 8331.0
If we take 83 away from 101, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
180 divided by 83 is 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 8331.2
If we subtract 166 from 180, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
The number 83 fits into 140 1 times, leaving a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 8331.21
Subtracting 83 from 140 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 9:
570 divided by 83 is 6 with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 8331.216
Deduct 498 from 570 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 10:
720 divided by 83 is 8 with a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 8331.2168
Deduct 664 from 720 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 11:
The number 83 fits into 560 6 times, leaving a remainder of 62.
The number 6 becomes the next digit in our result. 
Result so far: 8331.21686
If we take 498 away from 560, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 12:
If we divide 620 by 83, we get 7 and a remainder of 39.
Write down 7 as next digit of the result. 
Result so far: 8331.216867
The remainder is 39 after subtracting 581 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 13:
If we divide 390 by 83, we get 4 and a remainder of 58.
Write down 4 as next digit of the result. 
Result so far: 8331.2168674
Subtracting 332 from 390 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 14:
580 divided by 83 is 6 with a remainder of 82.
Record the quotient 6 as the next digit in the result. 
Result so far: 8331.21686746
If we subtract 498 from 580, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

The quotient of the division is 8331.21686746, and the remainder is 8.2e-08.
