We look at the division of 393659 by 73 
We want to divide 393659 by 73.

On to step 1:
When dividing 3 by 73, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 73

On to step 2:
The number 73 fits into 39 0 times, leaving a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 73

Going ahead to step 3:
The number 73 fits into 393 5 times, leaving a remainder of 28.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 365 away from 393, we end up with 28.
Bring next digit (6) of the dividend behind the 28 and repeat the process: 286 / 73

Let's proceed to step 4:
73 goes into 286 3 times with a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 53.0
If we subtract 219 from 286, we get 67.
Take the next digit (5) from the dividend and append it to 67, then repeat: 675 / 73

Moving on to step 5:
675 divided by 73 is 9 with a remainder of 18.
The next digit of our result is 9. 
Result so far: 539.0
Subtracting 657 from 675 leaves us with 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 73

Let's proceed to step 6:
If we divide 189 by 73, we get 2 and a remainder of 43.
Write down 2 as next digit of the result. 
Result so far: 5392.0
If we subtract 146 from 189, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 7:
The number 73 fits into 430 5 times, leaving a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 5392.5
If we take 365 away from 430, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 8:
73 can be fit into 650 8 times, resulting in a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 5392.58
If we take 584 away from 650, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 9:
73 goes into 660 9 times with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 5392.589
Subtract 657 from 660 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.

Let's proceed to step 10:
If we divide 30 by 73, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 5392.589
Deduct 0 from 30 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 11:
When dividing 300 by 73, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 5392.58904
If we subtract 292 from 300, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
73 can be fit into 80 1 times, resulting in a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 5392.589041
Subtract 73 from 80 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 13:
73 can be fit into 70 0 times, resulting in a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 5392.589041
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 14:
If we divide 700 by 73, we get 9 and a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 5392.58904109
If we subtract 657 from 700, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

The final outcome is 5392.58904109, with a leftover of 4.3e-08.
