Let's divide 52978920 by 664
We want to figure out the number of times 52978920 can be divided by 664.

On to step 1:
When dividing 5 by 664, we get 0 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 (2) from the dividend and append it to 5, then repeat: 52 / 664

Advancing to step 2:
52 divided by 664 is 0 with a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Include the next digit (9) from the dividend after 52, then repeat: 529 / 664

Moving on to step 3:
If we divide 529 by 664, we get 0 and a remainder of 529.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 529, we get 529.
Append the next digit (7) from the dividend to 529 and continue with: 5297 / 664

Step 4:
664 can be fit into 5297 7 times, resulting in a remainder of 649.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 4648 from 5297 and we're left with 649.
Take the next digit (8) from the dividend and append it to 649, then repeat: 6498 / 664

Going ahead to step 5:
If we divide 6498 by 664, we get 9 and a remainder of 522.
Use 9 as the next digit of our solution. 
Result so far: 79.0
If we take 5976 away from 6498, we end up with 522.
Fetch the next digit (9) from the dividend, attach it to 522 and continue: 5229 / 664

Let's proceed to step 6:
5229 divided by 664 is 7 with a remainder of 581.
Record the quotient 7 as the next digit in the result. 
Result so far: 797.0
Deduct 4648 from 5229 and we're left with 581.
Include the next digit (2) from the dividend after 581, then repeat: 5812 / 664

Let's proceed to step 7:
The number 664 fits into 5812 8 times, leaving a remainder of 500.
Write down 8 as next digit of the result. 
Result so far: 7978.0
Subtracting 5312 from 5812 leaves us with 500.
Bring next digit (0) of the dividend behind the 500 and repeat the process: 5000 / 664

Step 8:
If we divide 5000 by 664, we get 7 and a remainder of 352.
The next digit of our result is 7. 
Result so far: 79787.0
Subtracting 4648 from 5000 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Step 9:
When dividing 3520 by 664, we get 5 with a remainder of 200.
The number 5 becomes the next digit in our result. 
Result so far: 79787.5
Subtract 3320 from 3520 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.

Step 10:
664 can be fit into 2000 3 times, resulting in a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 79787.53
Subtract 1992 from 2000 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
80 divided by 664 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 79787.53
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 12:
664 goes into 800 1 times with a remainder of 136.
Record the quotient 1 as the next digit in the result. 
Result so far: 79787.5301
If we take 664 away from 800, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 13:
If we divide 1360 by 664, we get 2 and a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 79787.53012
If we take 1328 away from 1360, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 14:
When dividing 320 by 664, we get 0 with a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 79787.53012
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 15:
664 can be fit into 3200 4 times, resulting in a remainder of 544.
Use 4 as the next digit of our solution. 
Result so far: 79787.5301204
If we subtract 2656 from 3200, we get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Step 16:
When dividing 5440 by 664, we get 8 with a remainder of 128.
The next digit of our result is 8. 
Result so far: 79787.53012048
If we take 5312 away from 5440, we end up 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.

The quotient of the division is 79787.53012048, and the remainder is 1.28e-07.
