We look at the division of 387126 by 23 
Let's see how many times 23 fits into 387126.

Advancing to step 1:
23 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 23

Going ahead to step 2:
When dividing 38 by 23, we get 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 15 after subtracting 23 from 38.
Append the next digit (7) from the dividend to 15 and continue with: 157 / 23

Going ahead to step 3:
The number 23 fits into 157 6 times, leaving a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtracting 138 from 157 leaves us with 19.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 23

Advancing to step 4:
If we divide 191 by 23, we get 8 and a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 168.0
Subtract 184 from 191 to get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 23

Let's proceed to step 5:
If we divide 72 by 23, we get 3 and a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 1683.0
Subtracting 69 from 72 leaves us with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 23

Step 6:
If we divide 36 by 23, we get 1 and a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 16831.0
If we take 23 away from 36, we end up 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 7:
When dividing 130 by 23, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 16831.5
The remainder is 15 after subtracting 115 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 8:
The number 23 fits into 150 6 times, leaving a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 16831.56
If we take 138 away from 150, we end up 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 9:
120 divided by 23 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 16831.565
Subtract 115 from 120 to 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.

Step 10:
50 divided by 23 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 16831.5652
The remainder is 4 after subtracting 46 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
If we divide 40 by 23, we get 1 and a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 16831.56521
Subtract 23 from 40 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 12:
170 divided by 23 is 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 16831.565217
If we subtract 161 from 170, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 13:
When dividing 90 by 23, we get 3 with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 16831.5652173
If we subtract 69 from 90, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 14:
210 divided by 23 is 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 16831.56521739
If we subtract 207 from 210, 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.

The final result is 16831.56521739 with a remainder of 3e-09.
