We're dividing 438973 by 30 
We want to figure out the number of times 438973 can be divided by 30.

Let's proceed to step 1:
30 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 30

Advancing to step 2:
30 can be fit into 43 1 times, resulting in a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 13 after subtracting 30 from 43.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 30

Advancing to step 3:
30 can be fit into 138 4 times, resulting in a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Deduct 120 from 138 and we're left with 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 30

Going ahead to step 4:
When dividing 189 by 30, we get 6 with a remainder of 9.
The next digit of our result is 6. 
Result so far: 146.0
Subtract 180 from 189 to get 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 30

Advancing to step 5:
30 can be fit into 97 3 times, resulting in a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 1463.0
The remainder is 7 after subtracting 90 from 97.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 30

Going ahead to step 6:
30 can be fit into 73 2 times, resulting in a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 14632.0
Subtracting 60 from 73 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
If we divide 130 by 30, we get 4 and a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 14632.4
The remainder is 10 after subtracting 120 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
100 divided by 30 is 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 14632.43
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
100 divided by 30 is 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 14632.433
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 14632.433 with a remaining 0.001.
