We divide 17428387 by 503
Let's see how many times 503 fits into 17428387.

Advancing to step 1:
The number 503 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 503

Advancing to step 2:
503 goes into 17 0 times with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 503

Advancing to step 3:
503 goes into 174 0 times with a remainder of 174.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 174, we end up with 174.
Take the next digit (2) from the dividend and append it to 174, then repeat: 1742 / 503

On to step 4:
The number 503 fits into 1742 3 times, leaving a remainder of 233.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 1509 from 1742 leaves us with 233.
Take the next digit (8) from the dividend and append it to 233, then repeat: 2338 / 503

Let's proceed to step 5:
503 can be fit into 2338 4 times, resulting in a remainder of 326.
Write down 4 as next digit of the result. 
Result so far: 34.0
The remainder is 326 after subtracting 2012 from 2338.
Append the next digit (3) from the dividend to 326 and continue with: 3263 / 503

Advancing to step 6:
When dividing 3263 by 503, we get 6 with a remainder of 245.
The next digit of our result is 6. 
Result so far: 346.0
Subtract 3018 from 3263 to get 245.
Fetch the next digit (8) from the dividend, attach it to 245 and continue: 2458 / 503

Advancing to step 7:
503 goes into 2458 4 times with a remainder of 446.
Write down 4 as next digit of the result. 
Result so far: 3464.0
Subtract 2012 from 2458 to get 446.
Take the next digit (7) from the dividend and append it to 446, then repeat: 4467 / 503

Advancing to step 8:
503 can be fit into 4467 8 times, resulting in a remainder of 443.
Record the quotient 8 as the next digit in the result. 
Result so far: 34648.0
The remainder is 443 after subtracting 4024 from 4467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Advancing to step 9:
503 can be fit into 4430 8 times, resulting in a remainder of 406.
Put 8 as the next digit of the answer. 
Result so far: 34648.8
The remainder is 406 after subtracting 4024 from 4430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Let's proceed to step 10:
When dividing 4060 by 503, we get 8 with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 34648.88
If we subtract 4024 from 4060, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 34648.88, with a leftover of 0.036.
