We're dividing 15509302 by 787 
Our goal is to divide 15509302 by 787.

On to step 1:
The number 787 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 787

Advancing to step 2:
787 can be fit into 15 0 times, resulting in a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 787

On to step 3:
When dividing 155 by 787, we get 0 with a remainder of 155.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 155 after subtracting 0 from 155.
Append the next digit (0) from the dividend to 155 and continue with: 1550 / 787

Advancing to step 4:
787 can be fit into 1550 1 times, resulting in a remainder of 763.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 787 from 1550, we get 763.
Include the next digit (9) from the dividend after 763, then repeat: 7639 / 787

On to step 5:
787 can be fit into 7639 9 times, resulting in a remainder of 556.
Use 9 as the next digit of our solution. 
Result so far: 19.0
If we subtract 7083 from 7639, we get 556.
Include the next digit (3) from the dividend after 556, then repeat: 5563 / 787

Step 6:
787 can be fit into 5563 7 times, resulting in a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 197.0
The remainder is 54 after subtracting 5509 from 5563.
Fetch the next digit (0) from the dividend, attach it to 54 and continue: 540 / 787

Going ahead to step 7:
When dividing 540 by 787, we get 0 with a remainder of 540.
The next digit of our result is 0. 
Result so far: 1970.0
Subtracting 0 from 540 leaves us with 540.
Take the next digit (2) from the dividend and append it to 540, then repeat: 5402 / 787

On to step 8:
If we divide 5402 by 787, we get 6 and a remainder of 680.
Record the quotient 6 as the next digit in the result. 
Result so far: 19706.0
Subtracting 4722 from 5402 leaves us with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Moving on to step 9:
If we divide 6800 by 787, we get 8 and a remainder of 504.
Record the quotient 8 as the next digit in the result. 
Result so far: 19706.8
Subtract 6296 from 6800 to get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

On to step 10:
787 can be fit into 5040 6 times, resulting in a remainder of 318.
Put 6 as the next digit of the answer. 
Result so far: 19706.86
If we take 4722 away from 5040, we end up with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Let's proceed to step 11:
If we divide 3180 by 787, we get 4 and a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 19706.864
Deduct 3148 from 3180 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 12:
The number 787 fits into 320 0 times, leaving a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 19706.864
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 13:
787 can be fit into 3200 4 times, resulting in a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 19706.86404
Deduct 3148 from 3200 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 14:
787 goes into 520 0 times with a remainder of 520.
Put 0 as the next digit of the answer. 
Result so far: 19706.86404
Subtracting 0 from 520 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 15:
If we divide 5200 by 787, we get 6 and a remainder of 478.
Record the quotient 6 as the next digit in the result. 
Result so far: 19706.8640406
Subtract 4722 from 5200 to get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Moving on to step 16:
When dividing 4780 by 787, we get 6 with a remainder of 58.
Use 6 as the next digit of our solution. 
Result so far: 19706.86404066
The remainder is 58 after subtracting 4722 from 4780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The quotient of the division is 19706.86404066, and the remainder is 5.8e-08.
