Let's divide 8496407 by 249
The aim is to understand the frequency of 249 in 8496407.

Step 1:
249 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 249

Moving on to step 2:
When dividing 84 by 249, we get 0 with a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Bring next digit (9) of the dividend behind the 84 and repeat the process: 849 / 249

Step 3:
If we divide 849 by 249, we get 3 and a remainder of 102.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 747 away from 849, we end up with 102.
Append the next digit (6) from the dividend to 102 and continue with: 1026 / 249

On to step 4:
249 goes into 1026 4 times with a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
If we subtract 996 from 1026, we get 30.
Append the next digit (4) from the dividend to 30 and continue with: 304 / 249

Advancing to step 5:
If we divide 304 by 249, we get 1 and a remainder of 55.
The number 1 becomes the next digit in our result. 
Result so far: 341.0
Subtracting 249 from 304 leaves us with 55.
Append the next digit (0) from the dividend to 55 and continue with: 550 / 249

Step 6:
If we divide 550 by 249, we get 2 and a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 3412.0
Subtracting 498 from 550 leaves us with 52.
Take the next digit (7) from the dividend and append it to 52, then repeat: 527 / 249

Step 7:
The number 249 fits into 527 2 times, leaving a remainder of 29.
Put 2 as the next digit of the answer. 
Result so far: 34122.0
Deduct 498 from 527 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 8:
The number 249 fits into 290 1 times, leaving a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 34122.1
Subtract 249 from 290 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 9:
When dividing 410 by 249, we get 1 with a remainder of 161.
Put 1 as the next digit of the answer. 
Result so far: 34122.11
If we take 249 away from 410, we end up with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

The quotient of the division is 34122.11, and the remainder is 0.161.
