We divide 16509221 by 544
The aim is to understand the frequency of 544 in 16509221.

Moving on to step 1:
The number 544 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 544

Let's proceed to step 2:
544 goes into 16 0 times with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 544

On to step 3:
If we divide 165 by 544, we get 0 and a remainder of 165.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 165 and we're left with 165.
Take the next digit (0) from the dividend and append it to 165, then repeat: 1650 / 544

On to step 4:
When dividing 1650 by 544, we get 3 with a remainder of 18.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 1632 from 1650 and we're left with 18.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 544

Moving on to step 5:
The number 544 fits into 189 0 times, leaving a remainder of 189.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Deduct 0 from 189 and we're left with 189.
Append the next digit (2) from the dividend to 189 and continue with: 1892 / 544

Moving on to step 6:
1892 divided by 544 is 3 with a remainder of 260.
The number 3 becomes the next digit in our result. 
Result so far: 303.0
Deduct 1632 from 1892 and we're left with 260.
Take the next digit (2) from the dividend and append it to 260, then repeat: 2602 / 544

Advancing to step 7:
544 goes into 2602 4 times with a remainder of 426.
The next digit of our result is 4. 
Result so far: 3034.0
Subtracting 2176 from 2602 leaves us with 426.
Grab the next digit (1) from the dividend, add it to 426, then carry on: 4261 / 544

Going ahead to step 8:
544 can be fit into 4261 7 times, resulting in a remainder of 453.
The next digit of our result is 7. 
Result so far: 30347.0
Subtracting 3808 from 4261 leaves us with 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Let's proceed to step 9:
The number 544 fits into 4530 8 times, leaving a remainder of 178.
Put 8 as the next digit of the answer. 
Result so far: 30347.8
Subtract 4352 from 4530 to get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Step 10:
544 goes into 1780 3 times with a remainder of 148.
Put 3 as the next digit of the answer. 
Result so far: 30347.83
If we take 1632 away from 1780, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 11:
1480 divided by 544 is 2 with a remainder of 392.
The next digit of our result is 2. 
Result so far: 30347.832
Deduct 1088 from 1480 and we're left with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Moving on to step 12:
When dividing 3920 by 544, we get 7 with a remainder of 112.
The number 7 becomes the next digit in our result. 
Result so far: 30347.8327
Subtracting 3808 from 3920 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 13:
When dividing 1120 by 544, we get 2 with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 30347.83272
The remainder is 32 after subtracting 1088 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 14:
544 goes into 320 0 times with a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 30347.83272
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 15:
544 goes into 3200 5 times with a remainder of 480.
Put 5 as the next digit of the answer. 
Result so far: 30347.8327205
If we subtract 2720 from 3200, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 16:
544 goes into 4800 8 times with a remainder of 448.
The next digit of our result is 8. 
Result so far: 30347.83272058
Deduct 4352 from 4800 and we're left with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

The final outcome is 30347.83272058, with a leftover of 4.48e-07.
