We look at the division of 70284542 by 503 
Our goal is to divide 70284542 by 503.

Step 1:
503 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 503

On to step 2:
When dividing 70 by 503, we get 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Include the next digit (2) from the dividend after 70, then repeat: 702 / 503

Moving on to step 3:
When dividing 702 by 503, we get 1 with a remainder of 199.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 503 from 702 leaves us with 199.
Append the next digit (8) from the dividend to 199 and continue with: 1998 / 503

Advancing to step 4:
If we divide 1998 by 503, we get 3 and a remainder of 489.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 1509 from 1998 leaves us with 489.
Fetch the next digit (4) from the dividend, attach it to 489 and continue: 4894 / 503

Step 5:
4894 divided by 503 is 9 with a remainder of 367.
Use 9 as the next digit of our solution. 
Result so far: 139.0
If we take 4527 away from 4894, we end up with 367.
Grab the next digit (5) from the dividend, add it to 367, then carry on: 3675 / 503

Let's proceed to step 6:
If we divide 3675 by 503, we get 7 and a remainder of 154.
Record the quotient 7 as the next digit in the result. 
Result so far: 1397.0
The remainder is 154 after subtracting 3521 from 3675.
Append the next digit (4) from the dividend to 154 and continue with: 1544 / 503

Let's proceed to step 7:
When dividing 1544 by 503, we get 3 with a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 13973.0
Subtract 1509 from 1544 to get 35.
Grab the next digit (2) from the dividend, add it to 35, then carry on: 352 / 503

Advancing to step 8:
The number 503 fits into 352 0 times, leaving a remainder of 352.
Put 0 as the next digit of the answer. 
Result so far: 139730.0
The remainder is 352 after subtracting 0 from 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Step 9:
When dividing 3520 by 503, we get 6 with a remainder of 502.
Use 6 as the next digit of our solution. 
Result so far: 139730.6
If we take 3018 away from 3520, we end up with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Going ahead to step 10:
503 goes into 5020 9 times with a remainder of 493.
The next digit of our result is 9. 
Result so far: 139730.69
If we take 4527 away from 5020, we end up with 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Moving on to step 11:
503 can be fit into 4930 9 times, resulting in a remainder of 403.
Record the quotient 9 as the next digit in the result. 
Result so far: 139730.699
Deduct 4527 from 4930 and we're left with 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

After the division, we end up with 139730.699 and a remainder of 0.0403.
