780516 ÷ 51 
We want to divide 780516 by 51.

Let's proceed to step 1:
7 divided by 51 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 51

Going ahead to step 2:
51 can be fit into 78 1 times, resulting in a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 51 away from 78, we end up with 27.
Take the next digit (0) from the dividend and append it to 27, then repeat: 270 / 51

On to step 3:
The number 51 fits into 270 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 255 away from 270, we end up with 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 51

Let's proceed to step 4:
The number 51 fits into 155 3 times, leaving a remainder of 2.
The next digit of our result is 3. 
Result so far: 153.0
If we take 153 away from 155, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 51

Moving on to step 5:
51 goes into 21 0 times with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 1530.0
Subtracting 0 from 21 leaves us with 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 51

Advancing to step 6:
The number 51 fits into 216 4 times, leaving a remainder of 12.
The next digit of our result is 4. 
Result so far: 15304.0
If we subtract 204 from 216, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
51 can be fit into 120 2 times, resulting in a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 15304.2
If we subtract 102 from 120, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
The number 51 fits into 180 3 times, leaving a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 15304.23
The remainder is 27 after subtracting 153 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 9:
51 can be fit into 270 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 15304.235
Deduct 255 from 270 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 10:
If we divide 150 by 51, we get 2 and a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 15304.2352
Deduct 102 from 150 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 11:
51 can be fit into 480 9 times, resulting in a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 15304.23529
Subtract 459 from 480 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 12:
The number 51 fits into 210 4 times, leaving a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 15304.235294
Subtracting 204 from 210 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
If we divide 60 by 51, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 15304.2352941
The remainder is 9 after subtracting 51 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 14:
If we divide 90 by 51, we get 1 and a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 15304.23529411
Deduct 51 from 90 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

After the division, we end up with 15304.23529411 and a remainder of 3.9e-08.
