We're dividing 74583791 by 249 
The aim is to understand the frequency of 249 in 74583791.

Going ahead to step 1:
The number 249 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 249

Going ahead to step 2:
When dividing 74 by 249, we get 0 with a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Grab the next digit (5) from the dividend, add it to 74, then carry on: 745 / 249

Step 3:
249 can be fit into 745 2 times, resulting in a remainder of 247.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 498 away from 745, we end up with 247.
Include the next digit (8) from the dividend after 247, then repeat: 2478 / 249

On to step 4:
If we divide 2478 by 249, we get 9 and a remainder of 237.
Write down 9 as next digit of the result. 
Result so far: 29.0
If we subtract 2241 from 2478, we get 237.
Bring next digit (3) of the dividend behind the 237 and repeat the process: 2373 / 249

Let's proceed to step 5:
If we divide 2373 by 249, we get 9 and a remainder of 132.
Use 9 as the next digit of our solution. 
Result so far: 299.0
If we subtract 2241 from 2373, we get 132.
Take the next digit (7) from the dividend and append it to 132, then repeat: 1327 / 249

Advancing to step 6:
The number 249 fits into 1327 5 times, leaving a remainder of 82.
The number 5 becomes the next digit in our result. 
Result so far: 2995.0
Deduct 1245 from 1327 and we're left with 82.
Include the next digit (9) from the dividend after 82, then repeat: 829 / 249

Going ahead to step 7:
When dividing 829 by 249, we get 3 with a remainder of 82.
The next digit of our result is 3. 
Result so far: 29953.0
Deduct 747 from 829 and we're left with 82.
Fetch the next digit (1) from the dividend, attach it to 82 and continue: 821 / 249

Let's proceed to step 8:
When dividing 821 by 249, we get 3 with a remainder of 74.
The next digit of our result is 3. 
Result so far: 299533.0
Deduct 747 from 821 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 9:
249 can be fit into 740 2 times, resulting in a remainder of 242.
Record the quotient 2 as the next digit in the result. 
Result so far: 299533.2
Subtracting 498 from 740 leaves us with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Let's proceed to step 10:
249 can be fit into 2420 9 times, resulting in a remainder of 179.
The number 9 becomes the next digit in our result. 
Result so far: 299533.29
If we take 2241 away from 2420, we end up with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Going ahead to step 11:
The number 249 fits into 1790 7 times, leaving a remainder of 47.
The next digit of our result is 7. 
Result so far: 299533.297
Subtract 1743 from 1790 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 12:
249 can be fit into 470 1 times, resulting in a remainder of 221.
Write down 1 as next digit of the result. 
Result so far: 299533.2971
Subtract 249 from 470 to get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Let's proceed to step 13:
The number 249 fits into 2210 8 times, leaving a remainder of 218.
Write down 8 as next digit of the result. 
Result so far: 299533.29718
The remainder is 218 after subtracting 1992 from 2210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Advancing to step 14:
If we divide 2180 by 249, we get 8 and a remainder of 188.
Put 8 as the next digit of the answer. 
Result so far: 299533.297188
If we subtract 1992 from 2180, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

After the division, we end up with 299533.297188 and a remainder of 1.88e-05.
