590579 divided by 15 
Our goal is to divide 590579 by 15.

Step 1:
If we divide 5 by 15, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 15

Let's proceed to step 2:
15 goes into 59 3 times with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 45 from 59 and we're left with 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 15

Let's proceed to step 3:
If we divide 140 by 15, we get 9 and a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we take 135 away from 140, we end up with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 15

Let's proceed to step 4:
If we divide 55 by 15, we get 3 and a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 393.0
Subtract 45 from 55 to get 10.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 15

Going ahead to step 5:
When dividing 107 by 15, we get 7 with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 3937.0
Subtract 105 from 107 to get 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 15

Let's proceed to step 6:
15 can be fit into 29 1 times, resulting in a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 39371.0
Subtract 15 from 29 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
140 divided by 15 is 9 with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 39371.9
The remainder is 5 after subtracting 135 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
When dividing 50 by 15, we get 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 39371.93
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
15 goes into 50 3 times with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 39371.933
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 39371.933 with a remaining 0.0005.
