We look at the division of 638129 by 30 
Our goal is to divide 638129 by 30.

Moving on to step 1:
If we divide 6 by 30, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 30

Going ahead to step 2:
When dividing 63 by 30, we get 2 with a remainder of 3.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 60 from 63 and we're left with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 30

Step 3:
When dividing 38 by 30, we get 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 21.0
If we subtract 30 from 38, we get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 30

Going ahead to step 4:
81 divided by 30 is 2 with a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 212.0
If we subtract 60 from 81, we get 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 30

Advancing to step 5:
If we divide 212 by 30, we get 7 and a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 2127.0
If we take 210 away from 212, we end up with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 30

Advancing to step 6:
The number 30 fits into 29 0 times, leaving a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 21270.0
The remainder is 29 after subtracting 0 from 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 7:
If we divide 290 by 30, we get 9 and a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 21270.9
Deduct 270 from 290 and we're left 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.

Moving on to step 8:
30 goes into 200 6 times with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 21270.96
Deduct 180 from 200 and we're left 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.

Moving on to step 9:
When dividing 200 by 30, we get 6 with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 21270.966
Deduct 180 from 200 and we're left 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.

The quotient of the division is 21270.966, and the remainder is 0.002.
