Let's divide 539393 by 23
We want to divide 539393 by 23.

Step 1:
23 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 23

On to step 2:
23 can be fit into 53 2 times, resulting in a remainder of 7.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 46 from 53 and we're left with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 23

On to step 3:
23 can be fit into 79 3 times, resulting in a remainder of 10.
The next digit of our result is 3. 
Result so far: 23.0
Subtract 69 from 79 to get 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 23

Let's proceed to step 4:
If we divide 103 by 23, we get 4 and a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 234.0
Subtracting 92 from 103 leaves us with 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 23

Let's proceed to step 5:
If we divide 119 by 23, we get 5 and a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 2345.0
If we subtract 115 from 119, we get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 23

Going ahead to step 6:
23 can be fit into 43 1 times, resulting in a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 23451.0
The remainder is 20 after subtracting 23 from 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
When dividing 200 by 23, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 23451.8
The remainder is 16 after subtracting 184 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
The number 23 fits into 160 6 times, leaving a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 23451.86
If we subtract 138 from 160, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
If we divide 220 by 23, we get 9 and a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 23451.869
Deduct 207 from 220 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 10:
23 goes into 130 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 23451.8695
Deduct 115 from 130 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
23 goes into 150 6 times with a remainder of 12.
The next digit of our result is 6. 
Result so far: 23451.86956
Deduct 138 from 150 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
23 can be fit into 120 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 23451.869565
If we subtract 115 from 120, we 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.

Moving on to step 13:
The number 23 fits into 50 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 23451.8695652
If we take 46 away from 50, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
If we divide 40 by 23, we get 1 and a remainder of 17.
The next digit of our result is 1. 
Result so far: 23451.86956521
The remainder is 17 after subtracting 23 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final result is 23451.86956521 with a remainder of 1.7e-08.
