31438 divided by 30 
We want to figure out the number of times 31438 can be divided by 30.

Going ahead to step 1:
The number 30 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 30

Advancing to step 2:
30 can be fit into 31 1 times, resulting in a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 30 from 31 to get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 30

Let's proceed to step 3:
If we divide 14 by 30, we get 0 and a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 14 and we're left with 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 30

Moving on to step 4:
If we divide 143 by 30, we get 4 and a remainder of 23.
The next digit of our result is 4. 
Result so far: 104.0
If we subtract 120 from 143, we get 23.
Include the next digit (8) from the dividend after 23, then repeat: 238 / 30

Moving on to step 5:
30 can be fit into 238 7 times, resulting in a remainder of 28.
The next digit of our result is 7. 
Result so far: 1047.0
The remainder is 28 after subtracting 210 from 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 6:
280 divided by 30 is 9 with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 1047.9
If we take 270 away from 280, we end up 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.

Let's proceed to step 7:
When dividing 100 by 30, we get 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 1047.93
Deduct 90 from 100 and we're left 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.

Moving on to step 8:
30 goes into 100 3 times with a remainder of 10.
The next digit of our result is 3. 
Result so far: 1047.933
If we take 90 away from 100, we end up 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.

After the division, we end up with 1047.933 and a remainder of 0.001.
