We divide 71344163 by 648
The aim is to understand the frequency of 648 in 71344163.

Going ahead to step 1:
The number 648 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 648

Going ahead to step 2:
71 divided by 648 is 0 with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Grab the next digit (3) from the dividend, add it to 71, then carry on: 713 / 648

Going ahead to step 3:
When dividing 713 by 648, we get 1 with a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 648 from 713 and we're left with 65.
Append the next digit (4) from the dividend to 65 and continue with: 654 / 648

Moving on to step 4:
648 can be fit into 654 1 times, resulting in a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 648 from 654, we get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 648

On to step 5:
The number 648 fits into 64 0 times, leaving a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 110.0
The remainder is 64 after subtracting 0 from 64.
Append the next digit (1) from the dividend to 64 and continue with: 641 / 648

Advancing to step 6:
If we divide 641 by 648, we get 0 and a remainder of 641.
The next digit of our result is 0. 
Result so far: 1100.0
Subtracting 0 from 641 leaves us with 641.
Include the next digit (6) from the dividend after 641, then repeat: 6416 / 648

Advancing to step 7:
648 can be fit into 6416 9 times, resulting in a remainder of 584.
Use 9 as the next digit of our solution. 
Result so far: 11009.0
Subtract 5832 from 6416 to get 584.
Include the next digit (3) from the dividend after 584, then repeat: 5843 / 648

Let's proceed to step 8:
The number 648 fits into 5843 9 times, leaving a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 110099.0
If we take 5832 away from 5843, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
110 divided by 648 is 0 with a remainder of 110.
The number 0 becomes the next digit in our result. 
Result so far: 110099.0
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 10:
648 goes into 1100 1 times with a remainder of 452.
The next digit of our result is 1. 
Result so far: 110099.01
Deduct 648 from 1100 and we're left with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Going ahead to step 11:
648 can be fit into 4520 6 times, resulting in a remainder of 632.
The next digit of our result is 6. 
Result so far: 110099.016
Deduct 3888 from 4520 and we're left with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Step 12:
If we divide 6320 by 648, we get 9 and a remainder of 488.
Write down 9 as next digit of the result. 
Result so far: 110099.0169
Subtract 5832 from 6320 to get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Advancing to step 13:
If we divide 4880 by 648, we get 7 and a remainder of 344.
The number 7 becomes the next digit in our result. 
Result so far: 110099.01697
Subtracting 4536 from 4880 leaves us with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Moving on to step 14:
648 can be fit into 3440 5 times, resulting in a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 110099.016975
Deduct 3240 from 3440 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 15:
The number 648 fits into 2000 3 times, leaving a remainder of 56.
Record the quotient 3 as the next digit in the result. 
Result so far: 110099.0169753
If we take 1944 away from 2000, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 16:
560 divided by 648 is 0 with a remainder of 560.
Write down 0 as next digit of the result. 
Result so far: 110099.0169753
Subtract 0 from 560 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

After the division, we end up with 110099.0169753 and a remainder of 5.6e-07.
