20510742 ÷ 782 
We want to figure out the number of times 20510742 can be divided by 782.

Step 1:
782 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 782

On to step 2:
If we divide 20 by 782, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 782

Going ahead to step 3:
782 can be fit into 205 0 times, resulting in a remainder of 205.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 205 after subtracting 0 from 205.
Bring next digit (1) of the dividend behind the 205 and repeat the process: 2051 / 782

On to step 4:
When dividing 2051 by 782, we get 2 with a remainder of 487.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 1564 from 2051 to get 487.
Append the next digit (0) from the dividend to 487 and continue with: 4870 / 782

Let's proceed to step 5:
The number 782 fits into 4870 6 times, leaving a remainder of 178.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
Deduct 4692 from 4870 and we're left with 178.
Append the next digit (7) from the dividend to 178 and continue with: 1787 / 782

Going ahead to step 6:
782 can be fit into 1787 2 times, resulting in a remainder of 223.
Put 2 as the next digit of the answer. 
Result so far: 262.0
Deduct 1564 from 1787 and we're left with 223.
Include the next digit (4) from the dividend after 223, then repeat: 2234 / 782

Let's proceed to step 7:
The number 782 fits into 2234 2 times, leaving a remainder of 670.
The number 2 becomes the next digit in our result. 
Result so far: 2622.0
If we subtract 1564 from 2234, we get 670.
Include the next digit (2) from the dividend after 670, then repeat: 6702 / 782

Let's proceed to step 8:
When dividing 6702 by 782, we get 8 with a remainder of 446.
Record the quotient 8 as the next digit in the result. 
Result so far: 26228.0
Deduct 6256 from 6702 and we're left with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Moving on to step 9:
When dividing 4460 by 782, we get 5 with a remainder of 550.
The next digit of our result is 5. 
Result so far: 26228.5
Deduct 3910 from 4460 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Advancing to step 10:
782 can be fit into 5500 7 times, resulting in a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 26228.57
If we take 5474 away from 5500, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 11:
260 divided by 782 is 0 with a remainder of 260.
The next digit of our result is 0. 
Result so far: 26228.57
If we subtract 0 from 260, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 12:
When dividing 2600 by 782, we get 3 with a remainder of 254.
Write down 3 as next digit of the result. 
Result so far: 26228.5703
Subtracting 2346 from 2600 leaves us with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

On to step 13:
If we divide 2540 by 782, we get 3 and a remainder of 194.
Put 3 as the next digit of the answer. 
Result so far: 26228.57033
Subtracting 2346 from 2540 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

The final outcome is 26228.57033, with a leftover of 0.000194.
