663358 divided by 51 
We want to divide 663358 by 51.

Let's proceed to step 1:
6 divided by 51 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 51

Going ahead to step 2:
66 divided by 51 is 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 51 away from 66, we end up with 15.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 51

Let's proceed to step 3:
51 can be fit into 153 3 times, resulting in a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtract 153 from 153 to get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 51

Moving on to step 4:
If we divide 3 by 51, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 130.0
If we subtract 0 from 3, we get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 51

Step 5:
35 divided by 51 is 0 with a remainder of 35.
The next digit of our result is 0. 
Result so far: 1300.0
If we subtract 0 from 35, we get 35.
Take the next digit (8) from the dividend and append it to 35, then repeat: 358 / 51

Let's proceed to step 6:
358 divided by 51 is 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 13007.0
If we subtract 357 from 358, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
10 divided by 51 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 13007.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
When dividing 100 by 51, we get 1 with a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 13007.01
Subtract 51 from 100 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 9:
51 goes into 490 9 times with a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 13007.019
If we take 459 away from 490, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 10:
The number 51 fits into 310 6 times, leaving a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 13007.0196
Deduct 306 from 310 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
If we divide 40 by 51, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 13007.0196
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
The number 51 fits into 400 7 times, leaving a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 13007.019607
Subtract 357 from 400 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 13:
51 can be fit into 430 8 times, resulting in a remainder of 22.
The next digit of our result is 8. 
Result so far: 13007.0196078
If we subtract 408 from 430, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 14:
The number 51 fits into 220 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 13007.01960784
If we take 204 away from 220, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 13007.01960784, and the remainder is 1.6e-08.
