Let's divide 43360147 by 648
The aim is to understand the frequency of 648 in 43360147.

Step 1:
4 divided by 648 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 648

Moving on to step 2:
If we divide 43 by 648, we get 0 and a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Fetch the next digit (3) from the dividend, attach it to 43 and continue: 433 / 648

Moving on to step 3:
If we divide 433 by 648, we get 0 and a remainder of 433.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 433, we end up with 433.
Take the next digit (6) from the dividend and append it to 433, then repeat: 4336 / 648

Going ahead to step 4:
The number 648 fits into 4336 6 times, leaving a remainder of 448.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 3888 from 4336 to get 448.
Include the next digit (0) from the dividend after 448, then repeat: 4480 / 648

Let's proceed to step 5:
The number 648 fits into 4480 6 times, leaving a remainder of 592.
Write down 6 as next digit of the result. 
Result so far: 66.0
Subtracting 3888 from 4480 leaves us with 592.
Grab the next digit (1) from the dividend, add it to 592, then carry on: 5921 / 648

Step 6:
If we divide 5921 by 648, we get 9 and a remainder of 89.
The number 9 becomes the next digit in our result. 
Result so far: 669.0
If we take 5832 away from 5921, we end up with 89.
Take the next digit (4) from the dividend and append it to 89, then repeat: 894 / 648

Step 7:
If we divide 894 by 648, we get 1 and a remainder of 246.
The number 1 becomes the next digit in our result. 
Result so far: 6691.0
Subtract 648 from 894 to get 246.
Bring next digit (7) of the dividend behind the 246 and repeat the process: 2467 / 648

Moving on to step 8:
When dividing 2467 by 648, we get 3 with a remainder of 523.
Record the quotient 3 as the next digit in the result. 
Result so far: 66913.0
If we take 1944 away from 2467, we end up with 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Step 9:
The number 648 fits into 5230 8 times, leaving a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 66913.8
Subtract 5184 from 5230 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 10:
648 goes into 460 0 times with a remainder of 460.
The number 0 becomes the next digit in our result. 
Result so far: 66913.8
Subtract 0 from 460 to get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 11:
4600 divided by 648 is 7 with a remainder of 64.
Record the quotient 7 as the next digit in the result. 
Result so far: 66913.807
Subtract 4536 from 4600 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 12:
If we divide 640 by 648, we get 0 and a remainder of 640.
Put 0 as the next digit of the answer. 
Result so far: 66913.807
Deduct 0 from 640 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 13:
When dividing 6400 by 648, we get 9 with a remainder of 568.
The next digit of our result is 9. 
Result so far: 66913.80709
If we take 5832 away from 6400, we end up with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Let's proceed to step 14:
648 goes into 5680 8 times with a remainder of 496.
Write down 8 as next digit of the result. 
Result so far: 66913.807098
If we take 5184 away from 5680, we end up with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Advancing to step 15:
648 can be fit into 4960 7 times, resulting in a remainder of 424.
Put 7 as the next digit of the answer. 
Result so far: 66913.8070987
Subtracting 4536 from 4960 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Let's proceed to step 16:
648 can be fit into 4240 6 times, resulting in a remainder of 352.
Write down 6 as next digit of the result. 
Result so far: 66913.80709876
Deduct 3888 from 4240 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

After the division, we end up with 66913.80709876 and a remainder of 3.52e-07.
