397859 divided by 30 
We're looking to find how many times 30 goes into 397859.

Let's proceed to step 1:
If we divide 3 by 30, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 30

On to step 2:
The number 30 fits into 39 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 30 from 39 and we're left with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 30

Step 3:
When dividing 97 by 30, we get 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 90 from 97 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 30

Advancing to step 4:
78 divided by 30 is 2 with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 132.0
Subtracting 60 from 78 leaves us with 18.
Append the next digit (5) from the dividend to 18 and continue with: 185 / 30

Advancing to step 5:
185 divided by 30 is 6 with a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 1326.0
Deduct 180 from 185 and we're left with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 30

Going ahead to step 6:
30 can be fit into 59 1 times, resulting in a remainder of 29.
The next digit of our result is 1. 
Result so far: 13261.0
If we subtract 30 from 59, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 7:
The number 30 fits into 290 9 times, leaving a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 13261.9
The remainder is 20 after subtracting 270 from 290.
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.
Write down 6 as next digit of the result. 
Result so far: 13261.96
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.

Let's proceed to step 9:
If we divide 200 by 30, we get 6 and a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 13261.966
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.

After the division, we end up with 13261.966 and a remainder of 0.002.
