We look at the division of 3570071 by 503 
Let's see how many times 503 fits into 3570071.

Step 1:
If we divide 3 by 503, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 503

Step 2:
When dividing 35 by 503, we get 0 with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Append the next digit (7) from the dividend to 35 and continue with: 357 / 503

Let's proceed to step 3:
If we divide 357 by 503, we get 0 and a remainder of 357.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 357 to get 357.
Take the next digit (0) from the dividend and append it to 357, then repeat: 3570 / 503

Moving on to step 4:
When dividing 3570 by 503, we get 7 with a remainder of 49.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 3521 away from 3570, we end up with 49.
Include the next digit (0) from the dividend after 49, then repeat: 490 / 503

Going ahead to step 5:
If we divide 490 by 503, we get 0 and a remainder of 490.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
Subtracting 0 from 490 leaves us with 490.
Take the next digit (7) from the dividend and append it to 490, then repeat: 4907 / 503

On to step 6:
When dividing 4907 by 503, we get 9 with a remainder of 380.
Use 9 as the next digit of our solution. 
Result so far: 709.0
The remainder is 380 after subtracting 4527 from 4907.
Fetch the next digit (1) from the dividend, attach it to 380 and continue: 3801 / 503

Advancing to step 7:
If we divide 3801 by 503, we get 7 and a remainder of 280.
The next digit of our result is 7. 
Result so far: 7097.0
Subtract 3521 from 3801 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 8:
When dividing 2800 by 503, we get 5 with a remainder of 285.
Record the quotient 5 as the next digit in the result. 
Result so far: 7097.5
Subtract 2515 from 2800 to get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Going ahead to step 9:
2850 divided by 503 is 5 with a remainder of 335.
Put 5 as the next digit of the answer. 
Result so far: 7097.55
Deduct 2515 from 2850 and we're left with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

After the division, we end up with 7097.55 and a remainder of 0.335.
