We look at the division of 15479945 by 103 
Let's see how many times 103 fits into 15479945.

Moving on to step 1:
103 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 103

Moving on to step 2:
103 can be fit into 15 0 times, resulting in a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 103

Step 3:
154 divided by 103 is 1 with a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 103 from 154 to get 51.
Bring next digit (7) of the dividend behind the 51 and repeat the process: 517 / 103

Moving on to step 4:
103 goes into 517 5 times with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtracting 515 from 517 leaves us with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 103

Going ahead to step 5:
29 divided by 103 is 0 with a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 150.0
The remainder is 29 after subtracting 0 from 29.
Grab the next digit (9) from the dividend, add it to 29, then carry on: 299 / 103

Let's proceed to step 6:
299 divided by 103 is 2 with a remainder of 93.
The next digit of our result is 2. 
Result so far: 1502.0
Deduct 206 from 299 and we're left with 93.
Bring next digit (4) of the dividend behind the 93 and repeat the process: 934 / 103

Step 7:
103 goes into 934 9 times with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 15029.0
If we take 927 away from 934, we end up with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 103

Advancing to step 8:
If we divide 75 by 103, we get 0 and a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 150290.0
If we subtract 0 from 75, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 9:
When dividing 750 by 103, we get 7 with a remainder of 29.
The next digit of our result is 7. 
Result so far: 150290.7
If we take 721 away from 750, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 10:
103 can be fit into 290 2 times, resulting in a remainder of 84.
The number 2 becomes the next digit in our result. 
Result so far: 150290.72
Subtract 206 from 290 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 11:
The number 103 fits into 840 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 150290.728
Subtract 824 from 840 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 12:
103 goes into 160 1 times with a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 150290.7281
Subtract 103 from 160 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 13:
The number 103 fits into 570 5 times, leaving a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 150290.72815
If we take 515 away from 570, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 14:
103 can be fit into 550 5 times, resulting in a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 150290.728155
Subtracting 515 from 550 leaves us 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.

Our division results in 150290.728155 with a remaining 3.5e-06.
