We're dividing 364389 by 66 
We want to figure out the number of times 364389 can be divided by 66.

Going ahead to step 1:
The number 66 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 66

On to step 2:
If we divide 36 by 66, we get 0 and a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 36 after subtracting 0 from 36.
Append the next digit (4) from the dividend to 36 and continue with: 364 / 66

Advancing to step 3:
66 goes into 364 5 times with a remainder of 34.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 330 away from 364, we end up with 34.
Take the next digit (3) from the dividend and append it to 34, then repeat: 343 / 66

Advancing to step 4:
343 divided by 66 is 5 with a remainder of 13.
The next digit of our result is 5. 
Result so far: 55.0
Deduct 330 from 343 and we're left with 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 66

Advancing to step 5:
66 can be fit into 138 2 times, resulting in a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 552.0
The remainder is 6 after subtracting 132 from 138.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 66

Step 6:
69 divided by 66 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 5521.0
If we subtract 66 from 69, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
If we divide 30 by 66, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 5521.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
66 goes into 300 4 times with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 5521.04
The remainder is 36 after subtracting 264 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 9:
The number 66 fits into 360 5 times, leaving a remainder of 30.
The next digit of our result is 5. 
Result so far: 5521.045
Deduct 330 from 360 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
66 goes into 300 4 times with a remainder of 36.
The next digit of our result is 4. 
Result so far: 5521.0454
Subtract 264 from 300 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 11:
When dividing 360 by 66, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 5521.04545
Deduct 330 from 360 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
When dividing 300 by 66, we get 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 5521.045454
If we take 264 away from 300, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 13:
66 goes into 360 5 times with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 5521.0454545
Deduct 330 from 360 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 14:
When dividing 300 by 66, we get 4 with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 5521.04545454
Subtracting 264 from 300 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 5521.04545454 and a remainder of 3.6e-08.
