We divide 6388689 by 630
We're looking to find how many times 630 goes into 6388689.

Let's proceed to step 1:
630 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 630

Going ahead to step 2:
The number 630 fits into 63 0 times, leaving a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Fetch the next digit (8) from the dividend, attach it to 63 and continue: 638 / 630

Advancing to step 3:
If we divide 638 by 630, we get 1 and a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 8 after subtracting 630 from 638.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 630

Going ahead to step 4:
When dividing 88 by 630, we get 0 with a remainder of 88.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 88, we get 88.
Bring next digit (6) of the dividend behind the 88 and repeat the process: 886 / 630

Step 5:
The number 630 fits into 886 1 times, leaving a remainder of 256.
Write down 1 as next digit of the result. 
Result so far: 101.0
Subtract 630 from 886 to get 256.
Bring next digit (8) of the dividend behind the 256 and repeat the process: 2568 / 630

Let's proceed to step 6:
630 can be fit into 2568 4 times, resulting in a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 1014.0
The remainder is 48 after subtracting 2520 from 2568.
Append the next digit (9) from the dividend to 48 and continue with: 489 / 630

Going ahead to step 7:
630 can be fit into 489 0 times, resulting in a remainder of 489.
Record the quotient 0 as the next digit in the result. 
Result so far: 10140.0
Deduct 0 from 489 and we're left with 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Advancing to step 8:
4890 divided by 630 is 7 with a remainder of 480.
The number 7 becomes the next digit in our result. 
Result so far: 10140.7
If we take 4410 away from 4890, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 9:
630 can be fit into 4800 7 times, resulting in a remainder of 390.
The number 7 becomes the next digit in our result. 
Result so far: 10140.77
The remainder is 390 after subtracting 4410 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Our division results in 10140.77 with a remaining 0.39.
