We divide 239281 by 31
The aim is to understand the frequency of 31 in 239281.

Step 1:
If we divide 2 by 31, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 31

Let's proceed to step 2:
The number 31 fits into 23 0 times, leaving a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 31

Going ahead to step 3:
31 can be fit into 239 7 times, resulting in a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 217 from 239, we get 22.
Grab the next digit (2) from the dividend, add it to 22, then carry on: 222 / 31

Let's proceed to step 4:
The number 31 fits into 222 7 times, leaving a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
If we subtract 217 from 222, we get 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 31

Going ahead to step 5:
The number 31 fits into 58 1 times, leaving a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 771.0
The remainder is 27 after subtracting 31 from 58.
Bring next digit (1) of the dividend behind the 27 and repeat the process: 271 / 31

Moving on to step 6:
When dividing 271 by 31, we get 8 with a remainder of 23.
Put 8 as the next digit of the answer. 
Result so far: 7718.0
Subtract 248 from 271 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
230 divided by 31 is 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 7718.7
The remainder is 13 after subtracting 217 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 8:
When dividing 130 by 31, we get 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 7718.74
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 9:
If we divide 60 by 31, we get 1 and a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 7718.741
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.

Step 10:
31 can be fit into 290 9 times, resulting in a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 7718.7419
Subtract 279 from 290 to 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.

Going ahead to step 11:
31 can be fit into 110 3 times, resulting in a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 7718.74193
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 12:
31 can be fit into 170 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 7718.741935
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 13:
The number 31 fits into 150 4 times, leaving a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 7718.7419354
If we take 124 away from 150, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 14:
The number 31 fits into 260 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 7718.74193548
Subtract 248 from 260 to 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.

The quotient of the division is 7718.74193548, and the remainder is 1.2e-08.
