241912 ÷ 31 
The aim is to understand the frequency of 31 in 241912.

Step 1:
The number 31 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 31

On to step 2:
The number 31 fits into 24 0 times, leaving a remainder of 24.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 24, we get 24.
Fetch the next digit (1) from the dividend, attach it to 24 and continue: 241 / 31

Going ahead to step 3:
When dividing 241 by 31, we get 7 with a remainder of 24.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 217 from 241 to get 24.
Grab the next digit (9) from the dividend, add it to 24, then carry on: 249 / 31

Going ahead to step 4:
The number 31 fits into 249 8 times, leaving a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Deduct 248 from 249 and we're left with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 31

On to step 5:
When dividing 11 by 31, we get 0 with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 780.0
If we take 0 away from 11, we end up with 11.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 31

On to step 6:
The number 31 fits into 112 3 times, leaving a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 7803.0
The remainder is 19 after subtracting 93 from 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
The number 31 fits into 190 6 times, leaving a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 7803.6
If we subtract 186 from 190, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
31 goes into 40 1 times with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 7803.61
If we take 31 away from 40, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
90 divided by 31 is 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 7803.612
Deduct 62 from 90 and we're left 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.

Step 10:
280 divided by 31 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 7803.6129
Subtract 279 from 280 to 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.

Going ahead to step 11:
When dividing 10 by 31, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 7803.6129
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
When dividing 100 by 31, we get 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 7803.612903
Deduct 93 from 100 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 13:
70 divided by 31 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 7803.6129032
The remainder is 8 after subtracting 62 from 70.
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 14:
31 can be fit into 80 2 times, resulting in a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 7803.61290322
Deduct 62 from 80 and we're left 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.

The final result is 7803.61290322 with a remainder of 1.8e-08.
