536866 ÷ 30 
We want to figure out the number of times 536866 can be divided by 30.

Advancing to step 1:
30 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 30

Advancing to step 2:
53 divided by 30 is 1 with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 30 from 53 leaves us with 23.
Fetch the next digit (6) from the dividend, attach it to 23 and continue: 236 / 30

Moving on to step 3:
30 goes into 236 7 times with a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we take 210 away from 236, we end up with 26.
Fetch the next digit (8) from the dividend, attach it to 26 and continue: 268 / 30

Step 4:
The number 30 fits into 268 8 times, leaving a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 178.0
The remainder is 28 after subtracting 240 from 268.
Take the next digit (6) from the dividend and append it to 28, then repeat: 286 / 30

Advancing to step 5:
286 divided by 30 is 9 with a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 1789.0
Subtracting 270 from 286 leaves us with 16.
Take the next digit (6) from the dividend and append it to 16, then repeat: 166 / 30

Going ahead to step 6:
If we divide 166 by 30, we get 5 and a remainder of 16.
The next digit of our result is 5. 
Result so far: 17895.0
Subtracting 150 from 166 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
When dividing 160 by 30, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 17895.5
If we take 150 away from 160, 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.

Advancing to step 8:
100 divided by 30 is 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 17895.53
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
100 divided by 30 is 3 with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 17895.533
Subtract 90 from 100 to get 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 17895.533 and a remainder of 0.001.
