We look at the division of 389432 by 23 
We're looking to find how many times 23 goes into 389432.

Advancing to step 1:
23 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 23

Let's proceed to step 2:
38 divided by 23 is 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 23 from 38 leaves us with 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 23

Moving on to step 3:
159 divided by 23 is 6 with a remainder of 21.
Put 6 as the next digit of the answer. 
Result so far: 16.0
The remainder is 21 after subtracting 138 from 159.
Bring next digit (4) of the dividend behind the 21 and repeat the process: 214 / 23

Step 4:
214 divided by 23 is 9 with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 169.0
If we take 207 away from 214, we end up with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 23

Let's proceed to step 5:
23 can be fit into 73 3 times, resulting in a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 1693.0
The remainder is 4 after subtracting 69 from 73.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 23

Going ahead to step 6:
23 goes into 42 1 times with a remainder of 19.
The next digit of our result is 1. 
Result so far: 16931.0
Deduct 23 from 42 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
190 divided by 23 is 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 16931.8
Subtract 184 from 190 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
When dividing 60 by 23, we get 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 16931.82
Deduct 46 from 60 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 9:
23 can be fit into 140 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 16931.826
Subtract 138 from 140 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.

Step 10:
23 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 16931.826
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
When dividing 200 by 23, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 16931.82608
Subtract 184 from 200 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 12:
160 divided by 23 is 6 with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 16931.826086
Subtract 138 from 160 to 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.

Step 13:
When dividing 220 by 23, we get 9 with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 16931.8260869
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.

Going ahead to step 14:
If we divide 130 by 23, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 16931.82608695
Subtract 115 from 130 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 16931.82608695, and the remainder is 1.5e-08.
