300830 ÷ 31 
The aim is to understand the frequency of 31 in 300830.

Moving on to step 1:
When dividing 3 by 31, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 31

On to step 2:
When dividing 30 by 31, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 31

Moving on to step 3:
300 divided by 31 is 9 with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 21 after subtracting 279 from 300.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 31

Let's proceed to step 4:
218 divided by 31 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 97.0
Subtracting 217 from 218 leaves us with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 31

On to step 5:
If we divide 13 by 31, we get 0 and a remainder of 13.
The next digit of our result is 0. 
Result so far: 970.0
If we subtract 0 from 13, we get 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 31

On to step 6:
31 goes into 130 4 times with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 9704.0
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.

Step 7:
When dividing 60 by 31, we get 1 with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 9704.1
If we subtract 31 from 60, we 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.

Let's proceed to step 8:
290 divided by 31 is 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 9704.19
The remainder is 11 after subtracting 279 from 290.
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 9:
If we divide 110 by 31, we get 3 and a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 9704.193
The remainder is 17 after subtracting 93 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 10:
31 goes into 170 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 9704.1935
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.

Moving on to step 11:
If we divide 150 by 31, we get 4 and a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 9704.19354
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.

Going ahead to step 12:
If we divide 260 by 31, we get 8 and a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 9704.193548
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.

Moving on to step 13:
31 goes into 120 3 times with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 9704.1935483
Subtracting 93 from 120 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 14:
31 can be fit into 270 8 times, resulting in a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 9704.19354838
The remainder is 22 after subtracting 248 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The quotient of the division is 9704.19354838, and the remainder is 2.2e-08.
