We divide 393831 by 23
Our goal is to divide 393831 by 23.

On to step 1:
If we divide 3 by 23, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 23

Let's proceed to step 2:
When dividing 39 by 23, we get 1 with a remainder of 16.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 16 after subtracting 23 from 39.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 23

Step 3:
23 goes into 163 7 times with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Deduct 161 from 163 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 23

Advancing to step 4:
28 divided by 23 is 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 171.0
Subtracting 23 from 28 leaves us with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 23

Let's proceed to step 5:
53 divided by 23 is 2 with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 1712.0
If we take 46 away from 53, we end up with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 23

Let's proceed to step 6:
If we divide 71 by 23, we get 3 and a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 17123.0
Subtract 69 from 71 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
The number 23 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 17123.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
When dividing 200 by 23, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 17123.08
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 9:
The number 23 fits into 160 6 times, leaving a remainder of 22.
The next digit of our result is 6. 
Result so far: 17123.086
If we take 138 away from 160, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 10:
When dividing 220 by 23, we get 9 with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 17123.0869
The remainder is 13 after subtracting 207 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 11:
When dividing 130 by 23, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 17123.08695
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.

Going ahead to step 12:
23 goes into 150 6 times with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 17123.086956
The remainder is 12 after subtracting 138 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 13:
23 can be fit into 120 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 17123.0869565
The remainder is 5 after subtracting 115 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 14:
When dividing 50 by 23, we get 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 17123.08695652
Subtracting 46 from 50 leaves us 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.

The quotient of the division is 17123.08695652, and the remainder is 4e-09.
