Let's divide 389807 by 23
Our goal is to divide 389807 by 23.

Advancing to step 1:
23 goes into 3 0 times with 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.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 23

On to step 2:
38 divided by 23 is 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 23 from 38, we get 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 23

Let's proceed to step 3:
The number 23 fits into 159 6 times, leaving a remainder of 21.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we subtract 138 from 159, we get 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 23

On to step 4:
If we divide 218 by 23, we get 9 and a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 169.0
The remainder is 11 after subtracting 207 from 218.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 23

Let's proceed to step 5:
23 goes into 110 4 times with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 1694.0
The remainder is 18 after subtracting 92 from 110.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 23

Let's proceed to step 6:
23 goes into 187 8 times with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 16948.0
If we subtract 184 from 187, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
When dividing 30 by 23, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 16948.1
If we subtract 23 from 30, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 8:
The number 23 fits into 70 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 16948.13
If we take 69 away from 70, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
If we divide 10 by 23, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 16948.13
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
If we divide 100 by 23, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 16948.1304
Subtracting 92 from 100 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
When dividing 80 by 23, we get 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 16948.13043
If we subtract 69 from 80, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 12:
23 can be fit into 110 4 times, resulting in a remainder of 18.
The next digit of our result is 4. 
Result so far: 16948.130434
Subtract 92 from 110 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 13:
23 goes into 180 7 times with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 16948.1304347
Deduct 161 from 180 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.

Let's proceed to step 14:
When dividing 190 by 23, we get 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 16948.13043478
Deduct 184 from 190 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 16948.13043478, with a leftover of 6e-09.
