We're dividing 49117520 by 664 
The aim is to understand the frequency of 664 in 49117520.

Let's proceed to step 1:
When dividing 4 by 664, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 664

On to step 2:
If we divide 49 by 664, we get 0 and a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Append the next digit (1) from the dividend to 49 and continue with: 491 / 664

Going ahead to step 3:
If we divide 491 by 664, we get 0 and a remainder of 491.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 491, we end up with 491.
Grab the next digit (1) from the dividend, add it to 491, then carry on: 4911 / 664

On to step 4:
The number 664 fits into 4911 7 times, leaving a remainder of 263.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 4648 from 4911 to get 263.
Grab the next digit (7) from the dividend, add it to 263, then carry on: 2637 / 664

Moving on to step 5:
2637 divided by 664 is 3 with a remainder of 645.
Write down 3 as next digit of the result. 
Result so far: 73.0
If we subtract 1992 from 2637, we get 645.
Take the next digit (5) from the dividend and append it to 645, then repeat: 6455 / 664

Step 6:
If we divide 6455 by 664, we get 9 and a remainder of 479.
The next digit of our result is 9. 
Result so far: 739.0
If we subtract 5976 from 6455, we get 479.
Take the next digit (2) from the dividend and append it to 479, then repeat: 4792 / 664

On to step 7:
If we divide 4792 by 664, we get 7 and a remainder of 144.
The number 7 becomes the next digit in our result. 
Result so far: 7397.0
If we take 4648 away from 4792, we end up with 144.
Grab the next digit (0) from the dividend, add it to 144, then carry on: 1440 / 664

Going ahead to step 8:
When dividing 1440 by 664, we get 2 with a remainder of 112.
Put 2 as the next digit of the answer. 
Result so far: 73972.0
If we take 1328 away from 1440, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 9:
664 goes into 1120 1 times with a remainder of 456.
Record the quotient 1 as the next digit in the result. 
Result so far: 73972.1
Subtract 664 from 1120 to get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Moving on to step 10:
If we divide 4560 by 664, we get 6 and a remainder of 576.
The number 6 becomes the next digit in our result. 
Result so far: 73972.16
If we subtract 3984 from 4560, we get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Advancing to step 11:
5760 divided by 664 is 8 with a remainder of 448.
Use 8 as the next digit of our solution. 
Result so far: 73972.168
Subtract 5312 from 5760 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

On to step 12:
The number 664 fits into 4480 6 times, leaving a remainder of 496.
The number 6 becomes the next digit in our result. 
Result so far: 73972.1686
The remainder is 496 after subtracting 3984 from 4480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Step 13:
When dividing 4960 by 664, we get 7 with a remainder of 312.
The number 7 becomes the next digit in our result. 
Result so far: 73972.16867
Subtract 4648 from 4960 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Let's proceed to step 14:
3120 divided by 664 is 4 with a remainder of 464.
Record the quotient 4 as the next digit in the result. 
Result so far: 73972.168674
Deduct 2656 from 3120 and we're left with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Let's proceed to step 15:
664 can be fit into 4640 6 times, resulting in a remainder of 656.
The number 6 becomes the next digit in our result. 
Result so far: 73972.1686746
Subtracting 3984 from 4640 leaves us with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Let's proceed to step 16:
664 goes into 6560 9 times with a remainder of 584.
Record the quotient 9 as the next digit in the result. 
Result so far: 73972.16867469
Subtracting 5976 from 6560 leaves us with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

The final result is 73972.16867469 with a remainder of 5.84e-07.
