We look at the division of 51009571 by 784 
We're looking to find how many times 784 goes into 51009571.

Moving on to step 1:
784 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 784

Step 2:
If we divide 51 by 784, we get 0 and a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Take the next digit (0) from the dividend and append it to 51, then repeat: 510 / 784

Moving on to step 3:
If we divide 510 by 784, we get 0 and a remainder of 510.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 510, we end up with 510.
Take the next digit (0) from the dividend and append it to 510, then repeat: 5100 / 784

On to step 4:
When dividing 5100 by 784, we get 6 with a remainder of 396.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 4704 away from 5100, we end up with 396.
Bring next digit (9) of the dividend behind the 396 and repeat the process: 3969 / 784

Step 5:
784 can be fit into 3969 5 times, resulting in a remainder of 49.
Write down 5 as next digit of the result. 
Result so far: 65.0
Subtract 3920 from 3969 to get 49.
Bring next digit (5) of the dividend behind the 49 and repeat the process: 495 / 784

Let's proceed to step 6:
784 goes into 495 0 times with a remainder of 495.
The number 0 becomes the next digit in our result. 
Result so far: 650.0
If we subtract 0 from 495, we get 495.
Grab the next digit (7) from the dividend, add it to 495, then carry on: 4957 / 784

On to step 7:
4957 divided by 784 is 6 with a remainder of 253.
The number 6 becomes the next digit in our result. 
Result so far: 6506.0
Deduct 4704 from 4957 and we're left with 253.
Take the next digit (1) from the dividend and append it to 253, then repeat: 2531 / 784

Moving on to step 8:
784 goes into 2531 3 times with a remainder of 179.
The number 3 becomes the next digit in our result. 
Result so far: 65063.0
Subtracting 2352 from 2531 leaves us with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Advancing to step 9:
If we divide 1790 by 784, we get 2 and a remainder of 222.
Record the quotient 2 as the next digit in the result. 
Result so far: 65063.2
Subtracting 1568 from 1790 leaves us with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Step 10:
784 goes into 2220 2 times with a remainder of 652.
Write down 2 as next digit of the result. 
Result so far: 65063.22
Subtracting 1568 from 2220 leaves us with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

In conclusion, the division gives 65063.22 with a balance of 0.652.
