We divide 31315609 by 323
The aim is to understand the frequency of 323 in 31315609.

Step 1:
When dividing 3 by 323, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 323

Going ahead to step 2:
323 goes into 31 0 times with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Fetch the next digit (3) from the dividend, attach it to 31 and continue: 313 / 323

Going ahead to step 3:
If we divide 313 by 323, we get 0 and a remainder of 313.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 313 leaves us with 313.
Fetch the next digit (1) from the dividend, attach it to 313 and continue: 3131 / 323

Step 4:
323 can be fit into 3131 9 times, resulting in a remainder of 224.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 2907 from 3131 and we're left with 224.
Append the next digit (5) from the dividend to 224 and continue with: 2245 / 323

Moving on to step 5:
323 goes into 2245 6 times with a remainder of 307.
Use 6 as the next digit of our solution. 
Result so far: 96.0
Subtract 1938 from 2245 to get 307.
Include the next digit (6) from the dividend after 307, then repeat: 3076 / 323

On to step 6:
The number 323 fits into 3076 9 times, leaving a remainder of 169.
The next digit of our result is 9. 
Result so far: 969.0
Subtracting 2907 from 3076 leaves us with 169.
Include the next digit (0) from the dividend after 169, then repeat: 1690 / 323

Step 7:
The number 323 fits into 1690 5 times, leaving a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 9695.0
Subtract 1615 from 1690 to get 75.
Grab the next digit (9) from the dividend, add it to 75, then carry on: 759 / 323

Going ahead to step 8:
The number 323 fits into 759 2 times, leaving a remainder of 113.
Write down 2 as next digit of the result. 
Result so far: 96952.0
Subtracting 646 from 759 leaves us with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

On to step 9:
1130 divided by 323 is 3 with a remainder of 161.
Record the quotient 3 as the next digit in the result. 
Result so far: 96952.3
Subtracting 969 from 1130 leaves us with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

On to step 10:
323 goes into 1610 4 times with a remainder of 318.
Record the quotient 4 as the next digit in the result. 
Result so far: 96952.34
If we take 1292 away from 1610, we end up with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Advancing to step 11:
The number 323 fits into 3180 9 times, leaving a remainder of 273.
The number 9 becomes the next digit in our result. 
Result so far: 96952.349
The remainder is 273 after subtracting 2907 from 3180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

On to step 12:
323 goes into 2730 8 times with a remainder of 146.
Write down 8 as next digit of the result. 
Result so far: 96952.3498
Deduct 2584 from 2730 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Let's proceed to step 13:
323 goes into 1460 4 times with a remainder of 168.
Record the quotient 4 as the next digit in the result. 
Result so far: 96952.34984
If we subtract 1292 from 1460, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 14:
323 can be fit into 1680 5 times, resulting in a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 96952.349845
If we take 1615 away from 1680, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 15:
650 divided by 323 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 96952.3498452
Deduct 646 from 650 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 16:
323 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 96952.3498452
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 96952.3498452 with a remaining 4e-08.
