We look at the division of 51315885 by 783 
Let's see how many times 783 fits into 51315885.

On to step 1:
5 divided by 783 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 783

Step 2:
783 goes into 51 0 times with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Append the next digit (3) from the dividend to 51 and continue with: 513 / 783

On to step 3:
If we divide 513 by 783, we get 0 and a remainder of 513.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 513 and we're left with 513.
Bring next digit (1) of the dividend behind the 513 and repeat the process: 5131 / 783

Advancing to step 4:
When dividing 5131 by 783, we get 6 with a remainder of 433.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 4698 from 5131 to get 433.
Fetch the next digit (5) from the dividend, attach it to 433 and continue: 4335 / 783

Let's proceed to step 5:
If we divide 4335 by 783, we get 5 and a remainder of 420.
Write down 5 as next digit of the result. 
Result so far: 65.0
If we take 3915 away from 4335, we end up with 420.
Take the next digit (8) from the dividend and append it to 420, then repeat: 4208 / 783

Step 6:
4208 divided by 783 is 5 with a remainder of 293.
Write down 5 as next digit of the result. 
Result so far: 655.0
Subtracting 3915 from 4208 leaves us with 293.
Fetch the next digit (8) from the dividend, attach it to 293 and continue: 2938 / 783

On to step 7:
If we divide 2938 by 783, we get 3 and a remainder of 589.
Put 3 as the next digit of the answer. 
Result so far: 6553.0
The remainder is 589 after subtracting 2349 from 2938.
Fetch the next digit (5) from the dividend, attach it to 589 and continue: 5895 / 783

Going ahead to step 8:
When dividing 5895 by 783, we get 7 with a remainder of 414.
Use 7 as the next digit of our solution. 
Result so far: 65537.0
If we subtract 5481 from 5895, we get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

On to step 9:
The number 783 fits into 4140 5 times, leaving a remainder of 225.
Record the quotient 5 as the next digit in the result. 
Result so far: 65537.5
The remainder is 225 after subtracting 3915 from 4140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

On to step 10:
783 can be fit into 2250 2 times, resulting in a remainder of 684.
Put 2 as the next digit of the answer. 
Result so far: 65537.52
Subtracting 1566 from 2250 leaves us with 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

On to step 11:
6840 divided by 783 is 8 with a remainder of 576.
Put 8 as the next digit of the answer. 
Result so far: 65537.528
Subtract 6264 from 6840 to get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Let's proceed to step 12:
When dividing 5760 by 783, we get 7 with a remainder of 279.
Put 7 as the next digit of the answer. 
Result so far: 65537.5287
If we subtract 5481 from 5760, we get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Advancing to step 13:
783 can be fit into 2790 3 times, resulting in a remainder of 441.
The next digit of our result is 3. 
Result so far: 65537.52873
If we take 2349 away from 2790, we end up with 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Moving on to step 14:
If we divide 4410 by 783, we get 5 and a remainder of 495.
The next digit of our result is 5. 
Result so far: 65537.528735
The remainder is 495 after subtracting 3915 from 4410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Let's proceed to step 15:
When dividing 4950 by 783, we get 6 with a remainder of 252.
The next digit of our result is 6. 
Result so far: 65537.5287356
Deduct 4698 from 4950 and we're left with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 16:
If we divide 2520 by 783, we get 3 and a remainder of 171.
The number 3 becomes the next digit in our result. 
Result so far: 65537.52873563
Deduct 2349 from 2520 and we're left with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

The final result is 65537.52873563 with a remainder of 1.71e-07.
