Let's divide 729496 by 31
The aim is to understand the frequency of 31 in 729496.

Going ahead to step 1:
31 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 31

Let's proceed to step 2:
72 divided by 31 is 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 62 from 72 leaves us with 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 31

Step 3:
31 goes into 109 3 times with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we subtract 93 from 109, we get 16.
Bring next digit (4) of the dividend behind the 16 and repeat the process: 164 / 31

On to step 4:
When dividing 164 by 31, we get 5 with a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 235.0
If we take 155 away from 164, we end up with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 31

On to step 5:
31 goes into 99 3 times with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 2353.0
Deduct 93 from 99 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 31

Let's proceed to step 6:
66 divided by 31 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 23532.0
Subtracting 62 from 66 leaves us 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.

Step 7:
If we divide 40 by 31, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 23532.1
Subtract 31 from 40 to 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.

Let's proceed to step 8:
If we divide 90 by 31, we get 2 and a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 23532.12
Subtracting 62 from 90 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 9:
31 can be fit into 280 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 23532.129
If we subtract 279 from 280, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 10:
The number 31 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 23532.129
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
31 can be fit into 100 3 times, resulting in a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 23532.12903
If we subtract 93 from 100, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 12:
If we divide 70 by 31, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 23532.129032
Subtract 62 from 70 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
31 can be fit into 80 2 times, resulting in a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 23532.1290322
Subtracting 62 from 80 leaves us 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.

After the division, we end up with 23532.1290322 and a remainder of 1.8e-07.
