We look at the division of 16459509 by 393 
We're looking to find how many times 393 goes into 16459509.

Moving on to step 1:
1 divided by 393 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 393

Advancing to step 2:
If we divide 16 by 393, we get 0 and a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 393

Let's proceed to step 3:
When dividing 164 by 393, we get 0 with a remainder of 164.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 164 leaves us with 164.
Take the next digit (5) from the dividend and append it to 164, then repeat: 1645 / 393

Advancing to step 4:
393 goes into 1645 4 times with a remainder of 73.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 1572 from 1645 leaves us with 73.
Grab the next digit (9) from the dividend, add it to 73, then carry on: 739 / 393

Step 5:
393 can be fit into 739 1 times, resulting in a remainder of 346.
The next digit of our result is 1. 
Result so far: 41.0
If we subtract 393 from 739, we get 346.
Include the next digit (5) from the dividend after 346, then repeat: 3465 / 393

Going ahead to step 6:
When dividing 3465 by 393, we get 8 with a remainder of 321.
Use 8 as the next digit of our solution. 
Result so far: 418.0
If we take 3144 away from 3465, we end up with 321.
Include the next digit (0) from the dividend after 321, then repeat: 3210 / 393

Moving on to step 7:
The number 393 fits into 3210 8 times, leaving a remainder of 66.
Record the quotient 8 as the next digit in the result. 
Result so far: 4188.0
Deduct 3144 from 3210 and we're left with 66.
Bring next digit (9) of the dividend behind the 66 and repeat the process: 669 / 393

Let's proceed to step 8:
669 divided by 393 is 1 with a remainder of 276.
The number 1 becomes the next digit in our result. 
Result so far: 41881.0
Subtracting 393 from 669 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Advancing to step 9:
When dividing 2760 by 393, we get 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 41881.7
Subtracting 2751 from 2760 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 10:
The number 393 fits into 90 0 times, leaving a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 41881.7
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 11:
393 goes into 900 2 times with a remainder of 114.
Put 2 as the next digit of the answer. 
Result so far: 41881.702
Subtracting 786 from 900 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 12:
If we divide 1140 by 393, we get 2 and a remainder of 354.
The number 2 becomes the next digit in our result. 
Result so far: 41881.7022
Subtract 786 from 1140 to get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

The quotient of the division is 41881.7022, and the remainder is 0.00354.
