We look at the division of 15574235 by 630 
Our goal is to divide 15574235 by 630.

Going ahead to step 1:
When dividing 1 by 630, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 630

Going ahead to step 2:
630 can be fit into 15 0 times, resulting in a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 630

Step 3:
630 goes into 155 0 times with a remainder of 155.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 155 and we're left with 155.
Fetch the next digit (7) from the dividend, attach it to 155 and continue: 1557 / 630

Moving on to step 4:
1557 divided by 630 is 2 with a remainder of 297.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1260 from 1557 and we're left with 297.
Take the next digit (4) from the dividend and append it to 297, then repeat: 2974 / 630

On to step 5:
2974 divided by 630 is 4 with a remainder of 454.
The next digit of our result is 4. 
Result so far: 24.0
Deduct 2520 from 2974 and we're left with 454.
Include the next digit (2) from the dividend after 454, then repeat: 4542 / 630

Going ahead to step 6:
If we divide 4542 by 630, we get 7 and a remainder of 132.
Use 7 as the next digit of our solution. 
Result so far: 247.0
The remainder is 132 after subtracting 4410 from 4542.
Bring next digit (3) of the dividend behind the 132 and repeat the process: 1323 / 630

Let's proceed to step 7:
630 goes into 1323 2 times with a remainder of 63.
The number 2 becomes the next digit in our result. 
Result so far: 2472.0
Subtract 1260 from 1323 to get 63.
Append the next digit (5) from the dividend to 63 and continue with: 635 / 630

Moving on to step 8:
The number 630 fits into 635 1 times, leaving a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 24721.0
If we subtract 630 from 635, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
50 divided by 630 is 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 24721.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
When dividing 500 by 630, we get 0 with a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 24721.0
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final result is 24721.0 with a remainder of 0.5.
