45684031 ÷ 249 
The aim is to understand the frequency of 249 in 45684031.

Let's proceed to step 1:
When dividing 4 by 249, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 249

Let's proceed to step 2:
The number 249 fits into 45 0 times, leaving a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Append the next digit (6) from the dividend to 45 and continue with: 456 / 249

Moving on to step 3:
If we divide 456 by 249, we get 1 and a remainder of 207.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 249 from 456 to get 207.
Grab the next digit (8) from the dividend, add it to 207, then carry on: 2078 / 249

Going ahead to step 4:
249 goes into 2078 8 times with a remainder of 86.
The next digit of our result is 8. 
Result so far: 18.0
The remainder is 86 after subtracting 1992 from 2078.
Append the next digit (4) from the dividend to 86 and continue with: 864 / 249

Step 5:
The number 249 fits into 864 3 times, leaving a remainder of 117.
Put 3 as the next digit of the answer. 
Result so far: 183.0
If we subtract 747 from 864, we get 117.
Append the next digit (0) from the dividend to 117 and continue with: 1170 / 249

Going ahead to step 6:
If we divide 1170 by 249, we get 4 and a remainder of 174.
The number 4 becomes the next digit in our result. 
Result so far: 1834.0
Deduct 996 from 1170 and we're left with 174.
Grab the next digit (3) from the dividend, add it to 174, then carry on: 1743 / 249

On to step 7:
249 goes into 1743 7 times with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 18347.0
Subtracting 1743 from 1743 leaves us with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 249

Let's proceed to step 8:
The number 249 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 183470.0
Subtracting 0 from 1 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
10 divided by 249 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 183470.0
If we take 0 away from 10, we end up 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 10:
When dividing 100 by 249, we get 0 with a remainder of 100.
The next digit of our result is 0. 
Result so far: 183470.0
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

In conclusion, the division gives 183470.0 with a balance of 0.1.
