We're dividing 631088 by 30 
Our goal is to divide 631088 by 30.

On to step 1:
6 divided by 30 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 30

Let's proceed to step 2:
The number 30 fits into 63 2 times, leaving a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 60 from 63 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 30

Moving on to step 3:
The number 30 fits into 31 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Deduct 30 from 31 and we're left with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 30

Let's proceed to step 4:
10 divided by 30 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 210.0
Deduct 0 from 10 and we're left with 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 30

Let's proceed to step 5:
The number 30 fits into 108 3 times, leaving a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 2103.0
Subtracting 90 from 108 leaves us with 18.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 30

Let's proceed to step 6:
If we divide 188 by 30, we get 6 and a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 21036.0
Subtracting 180 from 188 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
If we divide 80 by 30, we get 2 and a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 21036.2
If we take 60 away from 80, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 21036.26
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
The number 30 fits into 200 6 times, leaving a remainder of 20.
The next digit of our result is 6. 
Result so far: 21036.266
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 21036.266 with a remaining 0.002.
