51329048 divided by 781 
We want to figure out the number of times 51329048 can be divided by 781.

Going ahead to step 1:
When dividing 5 by 781, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 781

On to step 2:
781 can be fit into 51 0 times, resulting in a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Grab the next digit (3) from the dividend, add it to 51, then carry on: 513 / 781

Going ahead to step 3:
The number 781 fits into 513 0 times, leaving a remainder of 513.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 513, we get 513.
Include the next digit (2) from the dividend after 513, then repeat: 5132 / 781

Moving on to step 4:
If we divide 5132 by 781, we get 6 and a remainder of 446.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 4686 from 5132 and we're left with 446.
Take the next digit (9) from the dividend and append it to 446, then repeat: 4469 / 781

Advancing to step 5:
When dividing 4469 by 781, we get 5 with a remainder of 564.
Put 5 as the next digit of the answer. 
Result so far: 65.0
If we subtract 3905 from 4469, we get 564.
Append the next digit (0) from the dividend to 564 and continue with: 5640 / 781

Step 6:
781 goes into 5640 7 times with a remainder of 173.
The number 7 becomes the next digit in our result. 
Result so far: 657.0
Subtracting 5467 from 5640 leaves us with 173.
Fetch the next digit (4) from the dividend, attach it to 173 and continue: 1734 / 781

Going ahead to step 7:
781 goes into 1734 2 times with a remainder of 172.
Put 2 as the next digit of the answer. 
Result so far: 6572.0
If we take 1562 away from 1734, we end up with 172.
Take the next digit (8) from the dividend and append it to 172, then repeat: 1728 / 781

Let's proceed to step 8:
1728 divided by 781 is 2 with a remainder of 166.
Use 2 as the next digit of our solution. 
Result so far: 65722.0
If we take 1562 away from 1728, we end up with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Let's proceed to step 9:
781 goes into 1660 2 times with a remainder of 98.
Use 2 as the next digit of our solution. 
Result so far: 65722.2
If we take 1562 away from 1660, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 10:
When dividing 980 by 781, we get 1 with a remainder of 199.
Record the quotient 1 as the next digit in the result. 
Result so far: 65722.21
If we take 781 away from 980, we end up with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Let's proceed to step 11:
If we divide 1990 by 781, we get 2 and a remainder of 428.
The number 2 becomes the next digit in our result. 
Result so far: 65722.212
If we subtract 1562 from 1990, we get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

On to step 12:
When dividing 4280 by 781, we get 5 with a remainder of 375.
The next digit of our result is 5. 
Result so far: 65722.2125
If we take 3905 away from 4280, we end up with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Step 13:
When dividing 3750 by 781, we get 4 with a remainder of 626.
The next digit of our result is 4. 
Result so far: 65722.21254
Subtracting 3124 from 3750 leaves us with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Step 14:
781 can be fit into 6260 8 times, resulting in a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 65722.212548
If we subtract 6248 from 6260, 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 15:
120 divided by 781 is 0 with a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 65722.212548
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 16:
If we divide 1200 by 781, we get 1 and a remainder of 419.
Record the quotient 1 as the next digit in the result. 
Result so far: 65722.21254801
If we subtract 781 from 1200, we get 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

After the division, we end up with 65722.21254801 and a remainder of 4.19e-07.
