We're dividing 868193 by 30 
We want to figure out the number of times 868193 can be divided by 30.

Advancing to step 1:
The number 30 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 30

Step 2:
When dividing 86 by 30, we get 2 with a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 60 from 86, we get 26.
Fetch the next digit (8) from the dividend, attach it to 26 and continue: 268 / 30

On to step 3:
268 divided by 30 is 8 with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we take 240 away from 268, we end up with 28.
Grab the next digit (1) from the dividend, add it to 28, then carry on: 281 / 30

Moving on to step 4:
30 goes into 281 9 times with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 289.0
Subtracting 270 from 281 leaves us with 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 30

Moving on to step 5:
The number 30 fits into 119 3 times, leaving a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 2893.0
If we subtract 90 from 119, we get 29.
Grab the next digit (3) from the dividend, add it to 29, then carry on: 293 / 30

Moving on to step 6:
The number 30 fits into 293 9 times, leaving a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 28939.0
Subtract 270 from 293 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
If we divide 230 by 30, we get 7 and a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 28939.7
If we subtract 210 from 230, we 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.

Advancing to step 8:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 28939.76
Subtracting 180 from 200 leaves us 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.

Moving on to step 9:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 28939.766
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.

After the division, we end up with 28939.766 and a remainder of 0.002.
