We're dividing 389889 by 23 
We're looking to find how many times 23 goes into 389889.

On to step 1:
The number 23 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 23

On to step 2:
23 goes into 38 1 times with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 15 after subtracting 23 from 38.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 23

Let's proceed to step 3:
When dividing 159 by 23, we get 6 with a remainder of 21.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we take 138 away from 159, we end up with 21.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 23

Advancing to step 4:
23 can be fit into 218 9 times, resulting in a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 169.0
Subtract 207 from 218 to get 11.
Take the next digit (8) from the dividend and append it to 11, then repeat: 118 / 23

Step 5:
118 divided by 23 is 5 with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 1695.0
Subtracting 115 from 118 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 23

Let's proceed to step 6:
If we divide 39 by 23, we get 1 and a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 16951.0
If we take 23 away from 39, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
If we divide 160 by 23, we get 6 and a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 16951.6
Subtracting 138 from 160 leaves us 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.

On to step 8:
The number 23 fits into 220 9 times, leaving a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 16951.69
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.

On to step 9:
The number 23 fits into 130 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 16951.695
If we subtract 115 from 130, we 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.

Step 10:
23 goes into 150 6 times with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 16951.6956
Subtract 138 from 150 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
23 can be fit into 120 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 16951.69565
If we take 115 away from 120, we end up 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.

On to step 12:
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: 16951.695652
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.

Moving on to step 13:
23 goes into 40 1 times with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 16951.6956521
Deduct 23 from 40 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 14:
The number 23 fits into 170 7 times, leaving a remainder of 9.
The next digit of our result is 7. 
Result so far: 16951.69565217
If we take 161 away from 170, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final outcome is 16951.69565217, with a leftover of 9e-09.
