15085540 divided by 103 
Let's see how many times 103 fits into 15085540.

Step 1:
The number 103 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 103

On to step 2:
If we divide 15 by 103, we get 0 and a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 103

Step 3:
103 can be fit into 150 1 times, resulting in a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 103 from 150 to get 47.
Fetch the next digit (8) from the dividend, attach it to 47 and continue: 478 / 103

Going ahead to step 4:
The number 103 fits into 478 4 times, leaving a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 412 from 478 to get 66.
Append the next digit (5) from the dividend to 66 and continue with: 665 / 103

Step 5:
If we divide 665 by 103, we get 6 and a remainder of 47.
Write down 6 as next digit of the result. 
Result so far: 146.0
Deduct 618 from 665 and we're left with 47.
Bring next digit (5) of the dividend behind the 47 and repeat the process: 475 / 103

Going ahead to step 6:
103 goes into 475 4 times with a remainder of 63.
The next digit of our result is 4. 
Result so far: 1464.0
Deduct 412 from 475 and we're left with 63.
Bring next digit (4) of the dividend behind the 63 and repeat the process: 634 / 103

Going ahead to step 7:
If we divide 634 by 103, we get 6 and a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 14646.0
Subtract 618 from 634 to get 16.
Take the next digit (0) from the dividend and append it to 16, then repeat: 160 / 103

Going ahead to step 8:
103 goes into 160 1 times with a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 146461.0
If we take 103 away from 160, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 9:
If we divide 570 by 103, we get 5 and a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 146461.5
If we subtract 515 from 570, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 10:
550 divided by 103 is 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 146461.55
If we take 515 away from 550, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 146461.55, and the remainder is 0.035.
