Let's divide 938690 by 30
We want to divide 938690 by 30.

Step 1:
If we divide 9 by 30, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 30

Advancing to step 2:
93 divided by 30 is 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 3 after subtracting 90 from 93.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 30

Going ahead to step 3:
38 divided by 30 is 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 31.0
The remainder is 8 after subtracting 30 from 38.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 30

Let's proceed to step 4:
The number 30 fits into 86 2 times, leaving a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 312.0
The remainder is 26 after subtracting 60 from 86.
Include the next digit (9) from the dividend after 26, then repeat: 269 / 30

Step 5:
30 can be fit into 269 8 times, resulting in a remainder of 29.
The number 8 becomes the next digit in our result. 
Result so far: 3128.0
Subtracting 240 from 269 leaves us with 29.
Grab the next digit (0) from the dividend, add it to 29, then carry on: 290 / 30

Moving on to step 6:
30 goes into 290 9 times with a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 31289.0
Subtract 270 from 290 to 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.

On to step 7:
200 divided by 30 is 6 with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 31289.6
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.

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: 31289.66
Subtract 180 from 200 to 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.

The final outcome is 31289.66, with a leftover of 0.02.
