We're dividing 15877648 by 786 
We want to divide 15877648 by 786.

Moving on to step 1:
The number 786 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 786

Step 2:
The number 786 fits into 15 0 times, leaving a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 786

On to step 3:
When dividing 158 by 786, we get 0 with a remainder of 158.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 158 leaves us with 158.
Grab the next digit (7) from the dividend, add it to 158, then carry on: 1587 / 786

Going ahead to step 4:
The number 786 fits into 1587 2 times, leaving a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 1572 from 1587 leaves us with 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 786

Going ahead to step 5:
The number 786 fits into 157 0 times, leaving a remainder of 157.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we take 0 away from 157, we end up with 157.
Include the next digit (6) from the dividend after 157, then repeat: 1576 / 786

Let's proceed to step 6:
1576 divided by 786 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 202.0
Deduct 1572 from 1576 and we're left with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 786

Going ahead to step 7:
44 divided by 786 is 0 with a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 2020.0
If we take 0 away from 44, we end up with 44.
Append the next digit (8) from the dividend to 44 and continue with: 448 / 786

Moving on to step 8:
The number 786 fits into 448 0 times, leaving a remainder of 448.
Use 0 as the next digit of our solution. 
Result so far: 20200.0
If we take 0 away from 448, we end up with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Going ahead to step 9:
The number 786 fits into 4480 5 times, leaving a remainder of 550.
The next digit of our result is 5. 
Result so far: 20200.5
If we take 3930 away from 4480, we end up 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.

Going ahead to step 10:
786 goes into 5500 6 times with a remainder of 784.
Write down 6 as next digit of the result. 
Result so far: 20200.56
The remainder is 784 after subtracting 4716 from 5500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

Advancing to step 11:
When dividing 7840 by 786, we get 9 with a remainder of 766.
Use 9 as the next digit of our solution. 
Result so far: 20200.569
Deduct 7074 from 7840 and we're left with 766.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7660, and continue the process.

Advancing to step 12:
786 can be fit into 7660 9 times, resulting in a remainder of 586.
The next digit of our result is 9. 
Result so far: 20200.5699
Subtracting 7074 from 7660 leaves us with 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

The quotient of the division is 20200.5699, and the remainder is 0.00586.
