401980 divided by 23 
We want to divide 401980 by 23.

Moving on to step 1:
23 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 23

Going ahead to step 2:
23 can be fit into 40 1 times, resulting in a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 23 from 40 leaves us with 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 23

Let's proceed to step 3:
23 can be fit into 171 7 times, resulting in a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 161 from 171, we get 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 23

On to step 4:
109 divided by 23 is 4 with a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 174.0
Subtract 92 from 109 to get 17.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 23

Advancing to step 5:
23 can be fit into 178 7 times, resulting in a remainder of 17.
The next digit of our result is 7. 
Result so far: 1747.0
If we take 161 away from 178, we end up with 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 23

Advancing to step 6:
170 divided by 23 is 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 17477.0
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.

Going ahead to step 7:
23 can be fit into 90 3 times, resulting in a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 17477.3
Subtracting 69 from 90 leaves us 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.

Going ahead to step 8:
When dividing 210 by 23, we get 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 17477.39
Subtract 207 from 210 to 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.

Let's proceed to step 9:
If we divide 30 by 23, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 17477.391
Subtracting 23 from 30 leaves us with 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 10:
The number 23 fits into 70 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 17477.3913
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 11:
10 divided by 23 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 17477.3913
Deduct 0 from 10 and we're left with 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 12:
100 divided by 23 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 17477.391304
If we subtract 92 from 100, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
23 goes into 80 3 times with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 17477.3913043
Subtracting 69 from 80 leaves us with 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 14:
23 goes into 110 4 times with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 17477.39130434
The remainder is 18 after subtracting 92 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 17477.39130434 with a balance of 1.8e-08.
