We look at the division of 593409 by 66 
Let's see how many times 66 fits into 593409.

Going ahead to step 1:
When dividing 5 by 66, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 66

Moving on to step 2:
When dividing 59 by 66, we get 0 with a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 59, we get 59.
Grab the next digit (3) from the dividend, add it to 59, then carry on: 593 / 66

Going ahead to step 3:
When dividing 593 by 66, we get 8 with a remainder of 65.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 528 from 593 leaves us with 65.
Grab the next digit (4) from the dividend, add it to 65, then carry on: 654 / 66

Step 4:
66 goes into 654 9 times with a remainder of 60.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
Deduct 594 from 654 and we're left with 60.
Include the next digit (0) from the dividend after 60, then repeat: 600 / 66

On to step 5:
66 goes into 600 9 times with a remainder of 6.
The next digit of our result is 9. 
Result so far: 899.0
Deduct 594 from 600 and we're left with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 66

Going ahead to step 6:
If we divide 69 by 66, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 8991.0
Subtract 66 from 69 to 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:
66 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 8991.0
Subtracting 0 from 30 leaves us 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.

Going ahead to step 8:
66 can be fit into 300 4 times, resulting in a remainder of 36.
The next digit of our result is 4. 
Result so far: 8991.04
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.

Advancing to step 9:
The number 66 fits into 360 5 times, leaving a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 8991.045
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.

Let's proceed to step 10:
When dividing 300 by 66, we get 4 with a remainder of 36.
The next digit of our result is 4. 
Result so far: 8991.0454
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.

Let's proceed to step 11:
The number 66 fits into 360 5 times, leaving a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 8991.04545
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.

Advancing to step 12:
The number 66 fits into 300 4 times, leaving a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 8991.045454
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.

Let's proceed to step 13:
When dividing 360 by 66, we get 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 8991.0454545
If we take 330 away from 360, we end up 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.

Step 14:
When dividing 300 by 66, we get 4 with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 8991.04545454
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.

The final result is 8991.04545454 with a remainder of 3.6e-08.
