We divide 49929041 by 648
The aim is to understand the frequency of 648 in 49929041.

Moving on to 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
If we subtract 0 from 4, we get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 648

Advancing to step 2:
648 can be fit into 49 0 times, resulting in a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 49, we end up with 49.
Include the next digit (9) from the dividend after 49, then repeat: 499 / 648

Let's proceed to step 3:
If we divide 499 by 648, we get 0 and a remainder of 499.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 499 after subtracting 0 from 499.
Take the next digit (2) from the dividend and append it to 499, then repeat: 4992 / 648

Advancing to step 4:
648 can be fit into 4992 7 times, resulting in a remainder of 456.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 4536 from 4992 and we're left with 456.
Append the next digit (9) from the dividend to 456 and continue with: 4569 / 648

Step 5:
If we divide 4569 by 648, we get 7 and a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 77.0
If we take 4536 away from 4569, we end up with 33.
Grab the next digit (0) from the dividend, add it to 33, then carry on: 330 / 648

Let's proceed to step 6:
The number 648 fits into 330 0 times, leaving a remainder of 330.
Use 0 as the next digit of our solution. 
Result so far: 770.0
Deduct 0 from 330 and we're left with 330.
Bring next digit (4) of the dividend behind the 330 and repeat the process: 3304 / 648

Step 7:
When dividing 3304 by 648, we get 5 with a remainder of 64.
Put 5 as the next digit of the answer. 
Result so far: 7705.0
The remainder is 64 after subtracting 3240 from 3304.
Take the next digit (1) from the dividend and append it to 64, then repeat: 641 / 648

Going ahead to step 8:
The number 648 fits into 641 0 times, leaving a remainder of 641.
The number 0 becomes the next digit in our result. 
Result so far: 77050.0
If we subtract 0 from 641, we get 641.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6410, and continue the process.

On to step 9:
If we divide 6410 by 648, we get 9 and a remainder of 578.
Use 9 as the next digit of our solution. 
Result so far: 77050.9
Deduct 5832 from 6410 and we're left with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Moving on to step 10:
648 can be fit into 5780 8 times, resulting in a remainder of 596.
Use 8 as the next digit of our solution. 
Result so far: 77050.98
Subtracting 5184 from 5780 leaves us with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Moving on to step 11:
If we divide 5960 by 648, we get 9 and a remainder of 128.
The number 9 becomes the next digit in our result. 
Result so far: 77050.989
Deduct 5832 from 5960 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 12:
When dividing 1280 by 648, we get 1 with a remainder of 632.
Put 1 as the next digit of the answer. 
Result so far: 77050.9891
Deduct 648 from 1280 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.

Moving on to step 13:
The number 648 fits into 6320 9 times, leaving a remainder of 488.
Use 9 as the next digit of our solution. 
Result so far: 77050.98919
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.

Moving on to step 14:
4880 divided by 648 is 7 with a remainder of 344.
Use 7 as the next digit of our solution. 
Result so far: 77050.989197
Deduct 4536 from 4880 and we're left 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.

On to step 15:
When dividing 3440 by 648, we get 5 with a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 77050.9891975
Subtract 3240 from 3440 to get 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 16:
648 goes into 2000 3 times with a remainder of 56.
Write down 3 as next digit of the result. 
Result so far: 77050.98919753
Subtracting 1944 from 2000 leaves us 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.

The final outcome is 77050.98919753, with a leftover of 5.6e-08.
