We're dividing 7871708 by 630 
We're looking to find how many times 630 goes into 7871708.

Step 1:
7 divided by 630 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 630

Let's proceed to step 2:
If we divide 78 by 630, we get 0 and a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Take the next digit (7) from the dividend and append it to 78, then repeat: 787 / 630

On to step 3:
If we divide 787 by 630, we get 1 and a remainder of 157.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 630 from 787 leaves us with 157.
Fetch the next digit (1) from the dividend, attach it to 157 and continue: 1571 / 630

Moving on to step 4:
1571 divided by 630 is 2 with a remainder of 311.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 1260 from 1571, we get 311.
Include the next digit (7) from the dividend after 311, then repeat: 3117 / 630

On to step 5:
630 goes into 3117 4 times with a remainder of 597.
Write down 4 as next digit of the result. 
Result so far: 124.0
Deduct 2520 from 3117 and we're left with 597.
Fetch the next digit (0) from the dividend, attach it to 597 and continue: 5970 / 630

Moving on to step 6:
The number 630 fits into 5970 9 times, leaving a remainder of 300.
Record the quotient 9 as the next digit in the result. 
Result so far: 1249.0
Deduct 5670 from 5970 and we're left with 300.
Append the next digit (8) from the dividend to 300 and continue with: 3008 / 630

Step 7:
630 goes into 3008 4 times with a remainder of 488.
Put 4 as the next digit of the answer. 
Result so far: 12494.0
Deduct 2520 from 3008 and we're left with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Advancing to step 8:
630 can be fit into 4880 7 times, resulting in a remainder of 470.
Use 7 as the next digit of our solution. 
Result so far: 12494.7
If we take 4410 away from 4880, we end up with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Step 9:
The number 630 fits into 4700 7 times, leaving a remainder of 290.
The number 7 becomes the next digit in our result. 
Result so far: 12494.77
Subtracting 4410 from 4700 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

The final result is 12494.77 with a remainder of 0.29.
