664880 ÷ 52 
We're looking to find how many times 52 goes into 664880.

Step 1:
If we divide 6 by 52, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 52

Let's proceed to step 2:
66 divided by 52 is 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 52 away from 66, we end up with 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 52

On to step 3:
52 goes into 144 2 times with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 104 from 144 leaves us with 40.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 52

On to step 4:
408 divided by 52 is 7 with a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 127.0
If we subtract 364 from 408, we get 44.
Bring next digit (8) of the dividend behind the 44 and repeat the process: 448 / 52

On to step 5:
52 goes into 448 8 times with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 1278.0
The remainder is 32 after subtracting 416 from 448.
Fetch the next digit (0) from the dividend, attach it to 32 and continue: 320 / 52

Moving on to step 6:
If we divide 320 by 52, we get 6 and a remainder of 8.
The next digit of our result is 6. 
Result so far: 12786.0
Subtracting 312 from 320 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
The number 52 fits into 80 1 times, leaving a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 12786.1
If we take 52 away from 80, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 8:
When dividing 280 by 52, we get 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 12786.15
Subtract 260 from 280 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
If we divide 200 by 52, we get 3 and a remainder of 44.
Write down 3 as next digit of the result. 
Result so far: 12786.153
Subtracting 156 from 200 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 10:
If we divide 440 by 52, we get 8 and a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 12786.1538
Subtract 416 from 440 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 11:
When dividing 240 by 52, we get 4 with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 12786.15384
Deduct 208 from 240 and we're left 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 12:
The number 52 fits into 320 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 12786.153846
The remainder is 8 after subtracting 312 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
52 can be fit into 80 1 times, resulting in a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 12786.1538461
Subtracting 52 from 80 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 14:
52 can be fit into 280 5 times, resulting in a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 12786.15384615
Deduct 260 from 280 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 12786.15384615 and a remainder of 2e-08.
