We're dividing 723956 by 31 
The aim is to understand the frequency of 31 in 723956.

Step 1:
If we divide 7 by 31, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 31

On to step 2:
When dividing 72 by 31, we get 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 10 after subtracting 62 from 72.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 31

Advancing to step 3:
103 divided by 31 is 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtract 93 from 103 to get 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 31

Step 4:
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: 233.0
The remainder is 16 after subtracting 93 from 109.
Take the next digit (5) from the dividend and append it to 16, then repeat: 165 / 31

Advancing to step 5:
When dividing 165 by 31, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 2335.0
If we subtract 155 from 165, we get 10.
Append the next digit (6) from the dividend to 10 and continue with: 106 / 31

Advancing to step 6:
31 goes into 106 3 times with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 23353.0
If we subtract 93 from 106, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
The number 31 fits into 130 4 times, leaving a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 23353.4
If we subtract 124 from 130, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
31 can be fit into 60 1 times, resulting in a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 23353.41
Subtract 31 from 60 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 9:
31 goes into 290 9 times with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 23353.419
If we subtract 279 from 290, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 10:
The number 31 fits into 110 3 times, leaving a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 23353.4193
If we subtract 93 from 110, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 11:
If we divide 170 by 31, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 23353.41935
Subtract 155 from 170 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 12:
The number 31 fits into 150 4 times, leaving a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 23353.419354
If we subtract 124 from 150, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 13:
When dividing 260 by 31, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 23353.4193548
If we subtract 248 from 260, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 14:
120 divided by 31 is 3 with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 23353.41935483
Subtract 93 from 120 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

In conclusion, the division gives 23353.41935483 with a balance of 2.7e-08.
