48884649 ÷ 648 
The aim is to understand the frequency of 648 in 48884649.

Step 1:
The number 648 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 648

Advancing to step 2:
The number 648 fits into 48 0 times, leaving a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 48, we end up with 48.
Grab the next digit (8) from the dividend, add it to 48, then carry on: 488 / 648

Advancing to step 3:
If we divide 488 by 648, we get 0 and a remainder of 488.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 488, we end up with 488.
Bring next digit (8) of the dividend behind the 488 and repeat the process: 4888 / 648

Let's proceed to step 4:
The number 648 fits into 4888 7 times, leaving a remainder of 352.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 4536 from 4888 to get 352.
Take the next digit (4) from the dividend and append it to 352, then repeat: 3524 / 648

Advancing to step 5:
The number 648 fits into 3524 5 times, leaving a remainder of 284.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
Subtract 3240 from 3524 to get 284.
Include the next digit (6) from the dividend after 284, then repeat: 2846 / 648

Let's proceed to step 6:
648 goes into 2846 4 times with a remainder of 254.
Put 4 as the next digit of the answer. 
Result so far: 754.0
If we subtract 2592 from 2846, we get 254.
Take the next digit (4) from the dividend and append it to 254, then repeat: 2544 / 648

Going ahead to step 7:
648 goes into 2544 3 times with a remainder of 600.
Write down 3 as next digit of the result. 
Result so far: 7543.0
Subtracting 1944 from 2544 leaves us with 600.
Bring next digit (9) of the dividend behind the 600 and repeat the process: 6009 / 648

Step 8:
648 goes into 6009 9 times with a remainder of 177.
The number 9 becomes the next digit in our result. 
Result so far: 75439.0
Subtracting 5832 from 6009 leaves us with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Step 9:
The number 648 fits into 1770 2 times, leaving a remainder of 474.
The next digit of our result is 2. 
Result so far: 75439.2
Subtracting 1296 from 1770 leaves us with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Advancing to step 10:
If we divide 4740 by 648, we get 7 and a remainder of 204.
Use 7 as the next digit of our solution. 
Result so far: 75439.27
If we subtract 4536 from 4740, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 11:
When dividing 2040 by 648, we get 3 with a remainder of 96.
Write down 3 as next digit of the result. 
Result so far: 75439.273
The remainder is 96 after subtracting 1944 from 2040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 12:
960 divided by 648 is 1 with a remainder of 312.
Use 1 as the next digit of our solution. 
Result so far: 75439.2731
Subtracting 648 from 960 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

On to step 13:
The number 648 fits into 3120 4 times, leaving a remainder of 528.
Write down 4 as next digit of the result. 
Result so far: 75439.27314
If we subtract 2592 from 3120, we get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Step 14:
648 can be fit into 5280 8 times, resulting in a remainder of 96.
Use 8 as the next digit of our solution. 
Result so far: 75439.273148
The remainder is 96 after subtracting 5184 from 5280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 15:
If we divide 960 by 648, we get 1 and a remainder of 312.
Put 1 as the next digit of the answer. 
Result so far: 75439.2731481
Deduct 648 from 960 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 16:
When dividing 3120 by 648, we get 4 with a remainder of 528.
Put 4 as the next digit of the answer. 
Result so far: 75439.27314814
Subtract 2592 from 3120 to get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

The quotient of the division is 75439.27314814, and the remainder is 5.28e-07.
