400150 ÷ 23 
Our goal is to divide 400150 by 23.

Step 1:
23 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 23

Going ahead to step 2:
When dividing 40 by 23, we get 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 23 from 40 and we're left with 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 23

Step 3:
The number 23 fits into 170 7 times, leaving a remainder of 9.
The next digit of our result is 7. 
Result so far: 17.0
Subtract 161 from 170 to get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 23

Moving on to step 4:
23 can be fit into 91 3 times, resulting in a remainder of 22.
The next digit of our result is 3. 
Result so far: 173.0
Deduct 69 from 91 and we're left with 22.
Bring next digit (5) of the dividend behind the 22 and repeat the process: 225 / 23

Moving on to step 5:
225 divided by 23 is 9 with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 1739.0
If we take 207 away from 225, we end up with 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 23

Let's proceed to step 6:
When dividing 180 by 23, we get 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 17397.0
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.

Going ahead to step 7:
If we divide 190 by 23, we get 8 and a remainder of 6.
The next digit of our result is 8. 
Result so far: 17397.8
If we take 184 away from 190, we end up 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.

Advancing to step 8:
23 goes into 60 2 times with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 17397.82
Subtract 46 from 60 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
23 goes into 140 6 times with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 17397.826
Deduct 138 from 140 and we're left with 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: 17397.826
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
200 divided by 23 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 17397.82608
The remainder is 16 after subtracting 184 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed 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: 17397.826086
If we take 138 away from 160, we end up 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.

Let's proceed to step 13:
The number 23 fits into 220 9 times, leaving a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 17397.8260869
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.

Step 14:
When dividing 130 by 23, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 17397.82608695
Subtracting 115 from 130 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.

After the division, we end up with 17397.82608695 and a remainder of 1.5e-08.
