We divide 386438 by 23
We want to figure out the number of times 386438 can be divided by 23.

Going ahead to step 1:
23 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 23

Step 2:
If we divide 38 by 23, we get 1 and a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 23 away from 38, we end up with 15.
Bring next digit (6) of the dividend behind the 15 and repeat the process: 156 / 23

On to step 3:
156 divided by 23 is 6 with a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 138 from 156 leaves us with 18.
Append the next digit (4) from the dividend to 18 and continue with: 184 / 23

Advancing to step 4:
When dividing 184 by 23, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 168.0
If we subtract 184 from 184, we get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 23

On to step 5:
23 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 1680.0
Subtract 0 from 3 to get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 23

Going ahead to step 6:
23 can be fit into 38 1 times, resulting in a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 16801.0
Subtracting 23 from 38 leaves us 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.

Moving on to step 7:
23 can be fit into 150 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 16801.6
Deduct 138 from 150 and we're left 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.

Let's proceed to step 8:
23 can be fit into 120 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 16801.65
If we subtract 115 from 120, we 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.

Going ahead to step 9:
If we divide 50 by 23, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 16801.652
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 10:
When dividing 40 by 23, we get 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 16801.6521
If we take 23 away from 40, we end up 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.

Moving on to step 11:
The number 23 fits into 170 7 times, leaving a remainder of 9.
The next digit of our result is 7. 
Result so far: 16801.65217
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.

Going ahead to step 12:
90 divided by 23 is 3 with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 16801.652173
Deduct 69 from 90 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 13:
23 can be fit into 210 9 times, resulting in a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 16801.6521739
Subtracting 207 from 210 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 14:
If we divide 30 by 23, we get 1 and a remainder of 7.
The next digit of our result is 1. 
Result so far: 16801.65217391
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.

The quotient of the division is 16801.65217391, and the remainder is 7e-09.
