We divide 286215 by 66
We're looking to find how many times 66 goes into 286215.

Going ahead to step 1:
The number 66 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 66

Going ahead to step 2:
The number 66 fits into 28 0 times, leaving a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Append the next digit (6) from the dividend to 28 and continue with: 286 / 66

Step 3:
The number 66 fits into 286 4 times, leaving a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 264 from 286 leaves us with 22.
Grab the next digit (2) from the dividend, add it to 22, then carry on: 222 / 66

On to step 4:
When dividing 222 by 66, we get 3 with a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Subtracting 198 from 222 leaves us with 24.
Fetch the next digit (1) from the dividend, attach it to 24 and continue: 241 / 66

Step 5:
66 can be fit into 241 3 times, resulting in a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 433.0
If we subtract 198 from 241, we get 43.
Take the next digit (5) from the dividend and append it to 43, then repeat: 435 / 66

On to step 6:
When dividing 435 by 66, we get 6 with a remainder of 39.
Use 6 as the next digit of our solution. 
Result so far: 4336.0
The remainder is 39 after subtracting 396 from 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 7:
390 divided by 66 is 5 with a remainder of 60.
The next digit of our result is 5. 
Result so far: 4336.5
If we subtract 330 from 390, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
66 goes into 600 9 times with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 4336.59
If we take 594 away from 600, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
66 goes into 60 0 times with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 4336.59
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
When dividing 600 by 66, we get 9 with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 4336.5909
Subtract 594 from 600 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 11:
60 divided by 66 is 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 4336.5909
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 12:
The number 66 fits into 600 9 times, leaving a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 4336.590909
Subtract 594 from 600 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
60 divided by 66 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 4336.590909
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 14:
When dividing 600 by 66, we get 9 with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 4336.59090909
The remainder is 6 after subtracting 594 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 4336.59090909 with a remainder of 6e-09.
