We're dividing 863457 by 30 
We want to figure out the number of times 863457 can be divided by 30.

Let's proceed to step 1:
8 divided by 30 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 30

Moving on to step 2:
When dividing 86 by 30, we get 2 with a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 60 from 86 and we're left with 26.
Take the next digit (3) from the dividend and append it to 26, then repeat: 263 / 30

Going ahead to step 3:
30 goes into 263 8 times with a remainder of 23.
Use 8 as the next digit of our solution. 
Result so far: 28.0
The remainder is 23 after subtracting 240 from 263.
Take the next digit (4) from the dividend and append it to 23, then repeat: 234 / 30

Advancing to step 4:
When dividing 234 by 30, we get 7 with a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 287.0
Deduct 210 from 234 and we're left with 24.
Append the next digit (5) from the dividend to 24 and continue with: 245 / 30

Let's proceed to step 5:
When dividing 245 by 30, we get 8 with a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 2878.0
If we subtract 240 from 245, we get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 30

Step 6:
57 divided by 30 is 1 with a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 28781.0
The remainder is 27 after subtracting 30 from 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 7:
The number 30 fits into 270 9 times, leaving a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 28781.9
Deduct 270 from 270 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
30 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 28781.9
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
0 divided by 30 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 28781.9
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 28781.9 with a remaining 0.0.
