3627239 ÷ 249 
The aim is to understand the frequency of 249 in 3627239.

Let's proceed to step 1:
The number 249 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 249

Step 2:
249 can be fit into 36 0 times, resulting in a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 36 after subtracting 0 from 36.
Bring next digit (2) of the dividend behind the 36 and repeat the process: 362 / 249

Going ahead to step 3:
249 goes into 362 1 times with a remainder of 113.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 249 from 362, we get 113.
Bring next digit (7) of the dividend behind the 113 and repeat the process: 1137 / 249

Advancing to step 4:
249 can be fit into 1137 4 times, resulting in a remainder of 141.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 996 from 1137 and we're left with 141.
Grab the next digit (2) from the dividend, add it to 141, then carry on: 1412 / 249

Going ahead to step 5:
The number 249 fits into 1412 5 times, leaving a remainder of 167.
Write down 5 as next digit of the result. 
Result so far: 145.0
Subtract 1245 from 1412 to get 167.
Include the next digit (3) from the dividend after 167, then repeat: 1673 / 249

On to step 6:
The number 249 fits into 1673 6 times, leaving a remainder of 179.
Use 6 as the next digit of our solution. 
Result so far: 1456.0
Deduct 1494 from 1673 and we're left with 179.
Grab the next digit (9) from the dividend, add it to 179, then carry on: 1799 / 249

Step 7:
When dividing 1799 by 249, we get 7 with a remainder of 56.
The next digit of our result is 7. 
Result so far: 14567.0
If we take 1743 away from 1799, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 8:
249 can be fit into 560 2 times, resulting in a remainder of 62.
The next digit of our result is 2. 
Result so far: 14567.2
If we subtract 498 from 560, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 9:
249 goes into 620 2 times with a remainder of 122.
The number 2 becomes the next digit in our result. 
Result so far: 14567.22
Deduct 498 from 620 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

The quotient of the division is 14567.22, and the remainder is 0.122.
