398776 ÷ 23 
We want to divide 398776 by 23.

Moving on to step 1:
23 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 23

Step 2:
23 can be fit into 39 1 times, resulting in a remainder of 16.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 23 from 39 leaves us with 16.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 23

Step 3:
If we divide 168 by 23, we get 7 and a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtract 161 from 168 to get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 23

Let's proceed to step 4:
23 can be fit into 77 3 times, resulting in a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 173.0
Deduct 69 from 77 and we're left with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 23

On to step 5:
23 can be fit into 87 3 times, resulting in a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 1733.0
If we take 69 away from 87, we end up with 18.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 23

Going ahead to step 6:
If we divide 186 by 23, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 17338.0
If we take 184 away from 186, we end up 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 7:
If we divide 20 by 23, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 17338.0
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.

On to step 8:
If we divide 200 by 23, we get 8 and a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 17338.08
Subtracting 184 from 200 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
If we divide 160 by 23, we get 6 and a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 17338.086
Subtracting 138 from 160 leaves us 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 10:
23 goes into 220 9 times with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 17338.0869
The remainder is 13 after subtracting 207 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 11:
If we divide 130 by 23, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 17338.08695
Deduct 115 from 130 and we're left 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.

On to step 12:
150 divided by 23 is 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 17338.086956
If we subtract 138 from 150, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
If we divide 120 by 23, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 17338.0869565
If we take 115 away from 120, we end up with 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 14:
The number 23 fits into 50 2 times, leaving a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 17338.08695652
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.

The final result is 17338.08695652 with a remainder of 4e-09.
