522638 ÷ 30 
We're looking to find how many times 30 goes into 522638.

Let's proceed to step 1:
The number 30 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 30

Advancing to step 2:
The number 30 fits into 52 1 times, leaving a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 30 from 52 leaves us with 22.
Fetch the next digit (2) from the dividend, attach it to 22 and continue: 222 / 30

Step 3:
The number 30 fits into 222 7 times, leaving a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Deduct 210 from 222 and we're left with 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 30

Advancing to step 4:
The number 30 fits into 126 4 times, leaving a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 174.0
Subtracting 120 from 126 leaves us with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 30

Let's proceed to step 5:
30 goes into 63 2 times with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 1742.0
Subtracting 60 from 63 leaves us with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 30

Advancing to step 6:
30 can be fit into 38 1 times, resulting in a remainder of 8.
The next digit of our result is 1. 
Result so far: 17421.0
If we subtract 30 from 38, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
30 goes into 80 2 times with a remainder of 20.
The next digit of our result is 2. 
Result so far: 17421.2
If we subtract 60 from 80, 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.

Let's proceed to step 8:
30 goes into 200 6 times with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 17421.26
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.

Step 9:
If we divide 200 by 30, we get 6 and a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 17421.266
If we take 180 away from 200, 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.

The final result is 17421.266 with a remainder of 0.002.
