We're dividing 51333549 by 664 
We want to figure out the number of times 51333549 can be divided by 664.

Step 1:
664 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 664

Step 2:
The number 664 fits into 51 0 times, leaving a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Bring next digit (3) of the dividend behind the 51 and repeat the process: 513 / 664

Advancing to step 3:
If we divide 513 by 664, we get 0 and a remainder of 513.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 513 and we're left with 513.
Append the next digit (3) from the dividend to 513 and continue with: 5133 / 664

Step 4:
664 goes into 5133 7 times with a remainder of 485.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 4648 away from 5133, we end up with 485.
Fetch the next digit (3) from the dividend, attach it to 485 and continue: 4853 / 664

Advancing to step 5:
The number 664 fits into 4853 7 times, leaving a remainder of 205.
Write down 7 as next digit of the result. 
Result so far: 77.0
Subtract 4648 from 4853 to get 205.
Append the next digit (5) from the dividend to 205 and continue with: 2055 / 664

Advancing to step 6:
664 can be fit into 2055 3 times, resulting in a remainder of 63.
Record the quotient 3 as the next digit in the result. 
Result so far: 773.0
If we subtract 1992 from 2055, we get 63.
Include the next digit (4) from the dividend after 63, then repeat: 634 / 664

Moving on to step 7:
When dividing 634 by 664, we get 0 with a remainder of 634.
The number 0 becomes the next digit in our result. 
Result so far: 7730.0
Subtracting 0 from 634 leaves us with 634.
Grab the next digit (9) from the dividend, add it to 634, then carry on: 6349 / 664

Going ahead to step 8:
When dividing 6349 by 664, we get 9 with a remainder of 373.
Use 9 as the next digit of our solution. 
Result so far: 77309.0
The remainder is 373 after subtracting 5976 from 6349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Step 9:
664 goes into 3730 5 times with a remainder of 410.
The next digit of our result is 5. 
Result so far: 77309.5
If we take 3320 away from 3730, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 10:
If we divide 4100 by 664, we get 6 and a remainder of 116.
Record the quotient 6 as the next digit in the result. 
Result so far: 77309.56
Deduct 3984 from 4100 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 11:
The number 664 fits into 1160 1 times, leaving a remainder of 496.
The next digit of our result is 1. 
Result so far: 77309.561
If we subtract 664 from 1160, we get 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 12:
The number 664 fits into 4960 7 times, leaving a remainder of 312.
Use 7 as the next digit of our solution. 
Result so far: 77309.5617
The remainder is 312 after subtracting 4648 from 4960.
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:
If we divide 3120 by 664, we get 4 and a remainder of 464.
The number 4 becomes the next digit in our result. 
Result so far: 77309.56174
If we take 2656 away from 3120, we end up 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.

Going ahead to step 14:
The number 664 fits into 4640 6 times, leaving a remainder of 656.
Record the quotient 6 as the next digit in the result. 
Result so far: 77309.561746
If we take 3984 away from 4640, we end up 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.

Advancing to step 15:
If we divide 6560 by 664, we get 9 and a remainder of 584.
Put 9 as the next digit of the answer. 
Result so far: 77309.5617469
The remainder is 584 after subtracting 5976 from 6560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Moving on to step 16:
The number 664 fits into 5840 8 times, leaving a remainder of 528.
Write down 8 as next digit of the result. 
Result so far: 77309.56174698
The remainder is 528 after subtracting 5312 from 5840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

In conclusion, the division gives 77309.56174698 with a balance of 5.28e-07.
