We're dividing 16186339 by 624 
The aim is to understand the frequency of 624 in 16186339.

Going ahead to step 1:
624 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 624

On to step 2:
If we divide 16 by 624, we get 0 and a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 624

On to step 3:
When dividing 161 by 624, we get 0 with a remainder of 161.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 161 to get 161.
Grab the next digit (8) from the dividend, add it to 161, then carry on: 1618 / 624

Step 4:
1618 divided by 624 is 2 with a remainder of 370.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 1248 from 1618 and we're left with 370.
Append the next digit (6) from the dividend to 370 and continue with: 3706 / 624

Let's proceed to step 5:
624 can be fit into 3706 5 times, resulting in a remainder of 586.
The next digit of our result is 5. 
Result so far: 25.0
Subtracting 3120 from 3706 leaves us with 586.
Include the next digit (3) from the dividend after 586, then repeat: 5863 / 624

Moving on to step 6:
624 goes into 5863 9 times with a remainder of 247.
Write down 9 as next digit of the result. 
Result so far: 259.0
If we take 5616 away from 5863, we end up with 247.
Fetch the next digit (3) from the dividend, attach it to 247 and continue: 2473 / 624

Moving on to step 7:
624 goes into 2473 3 times with a remainder of 601.
The number 3 becomes the next digit in our result. 
Result so far: 2593.0
Subtract 1872 from 2473 to get 601.
Bring next digit (9) of the dividend behind the 601 and repeat the process: 6019 / 624

Step 8:
624 goes into 6019 9 times with a remainder of 403.
The next digit of our result is 9. 
Result so far: 25939.0
If we subtract 5616 from 6019, we get 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

On to step 9:
If we divide 4030 by 624, we get 6 and a remainder of 286.
Put 6 as the next digit of the answer. 
Result so far: 25939.6
If we subtract 3744 from 4030, we get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Going ahead to step 10:
624 goes into 2860 4 times with a remainder of 364.
Write down 4 as next digit of the result. 
Result so far: 25939.64
The remainder is 364 after subtracting 2496 from 2860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Advancing to step 11:
624 goes into 3640 5 times with a remainder of 520.
Put 5 as the next digit of the answer. 
Result so far: 25939.645
Deduct 3120 from 3640 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 12:
5200 divided by 624 is 8 with a remainder of 208.
The number 8 becomes the next digit in our result. 
Result so far: 25939.6458
Deduct 4992 from 5200 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 13:
The number 624 fits into 2080 3 times, leaving a remainder of 208.
The next digit of our result is 3. 
Result so far: 25939.64583
The remainder is 208 after subtracting 1872 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 14:
624 can be fit into 2080 3 times, resulting in a remainder of 208.
The next digit of our result is 3. 
Result so far: 25939.645833
If we subtract 1872 from 2080, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

In conclusion, the division gives 25939.645833 with a balance of 2.08e-05.
