14404053 divided by 648 
The aim is to understand the frequency of 648 in 14404053.

Let's proceed to step 1:
648 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 648

Moving on to step 2:
648 can be fit into 14 0 times, resulting in a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Bring next digit (4) of the dividend behind the 14 and repeat the process: 144 / 648

Advancing to step 3:
If we divide 144 by 648, we get 0 and a remainder of 144.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 144, we get 144.
Bring next digit (0) of the dividend behind the 144 and repeat the process: 1440 / 648

Going ahead to step 4:
When dividing 1440 by 648, we get 2 with a remainder of 144.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 1296 from 1440, we get 144.
Bring next digit (4) of the dividend behind the 144 and repeat the process: 1444 / 648

Moving on to step 5:
648 can be fit into 1444 2 times, resulting in a remainder of 148.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we subtract 1296 from 1444, we get 148.
Append the next digit (0) from the dividend to 148 and continue with: 1480 / 648

Let's proceed to step 6:
The number 648 fits into 1480 2 times, leaving a remainder of 184.
Write down 2 as next digit of the result. 
Result so far: 222.0
The remainder is 184 after subtracting 1296 from 1480.
Include the next digit (5) from the dividend after 184, then repeat: 1845 / 648

Moving on to step 7:
If we divide 1845 by 648, we get 2 and a remainder of 549.
Write down 2 as next digit of the result. 
Result so far: 2222.0
Subtracting 1296 from 1845 leaves us with 549.
Fetch the next digit (3) from the dividend, attach it to 549 and continue: 5493 / 648

On to step 8:
648 can be fit into 5493 8 times, resulting in a remainder of 309.
Record the quotient 8 as the next digit in the result. 
Result so far: 22228.0
The remainder is 309 after subtracting 5184 from 5493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Moving on to step 9:
648 can be fit into 3090 4 times, resulting in a remainder of 498.
Record the quotient 4 as the next digit in the result. 
Result so far: 22228.4
Deduct 2592 from 3090 and we're left with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Step 10:
648 can be fit into 4980 7 times, resulting in a remainder of 444.
Write down 7 as next digit of the result. 
Result so far: 22228.47
The remainder is 444 after subtracting 4536 from 4980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

On to step 11:
When dividing 4440 by 648, we get 6 with a remainder of 552.
Record the quotient 6 as the next digit in the result. 
Result so far: 22228.476
Subtract 3888 from 4440 to get 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Moving on to step 12:
The number 648 fits into 5520 8 times, leaving a remainder of 336.
Record the quotient 8 as the next digit in the result. 
Result so far: 22228.4768
Subtracting 5184 from 5520 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 13:
648 goes into 3360 5 times with a remainder of 120.
The next digit of our result is 5. 
Result so far: 22228.47685
Subtracting 3240 from 3360 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 14:
648 goes into 1200 1 times with a remainder of 552.
Put 1 as the next digit of the answer. 
Result so far: 22228.476851
The remainder is 552 after subtracting 648 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Step 15:
648 goes into 5520 8 times with a remainder of 336.
The next digit of our result is 8. 
Result so far: 22228.4768518
Deduct 5184 from 5520 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 16:
When dividing 3360 by 648, we get 5 with a remainder of 120.
Write down 5 as next digit of the result. 
Result so far: 22228.47685185
If we take 3240 away from 3360, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

After the division, we end up with 22228.47685185 and a remainder of 1.2e-07.
