279213 ÷ 23 
We want to divide 279213 by 23.

Going ahead to step 1:
When dividing 2 by 23, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 23

Let's proceed to step 2:
27 divided by 23 is 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 23 away from 27, we end up with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 23

Going ahead to step 3:
49 divided by 23 is 2 with a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 46 from 49 leaves us with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 23

Step 4:
23 can be fit into 32 1 times, resulting in a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 121.0
Subtracting 23 from 32 leaves us with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 23

Going ahead to step 5:
The number 23 fits into 91 3 times, leaving a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 1213.0
If we take 69 away from 91, we end up with 22.
Include the next digit (3) from the dividend after 22, then repeat: 223 / 23

Advancing to step 6:
The number 23 fits into 223 9 times, leaving a remainder of 16.
Record the quotient 9 as the next digit in the result. 
Result so far: 12139.0
Subtracting 207 from 223 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.

Advancing to step 7:
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: 12139.6
The remainder is 22 after subtracting 138 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 8:
23 goes into 220 9 times with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 12139.69
If we subtract 207 from 220, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 9:
23 goes into 130 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 12139.695
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.

Moving on to step 10:
If we divide 150 by 23, we get 6 and a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 12139.6956
Subtracting 138 from 150 leaves us 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.

Going ahead to step 11:
120 divided by 23 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 12139.69565
Subtracting 115 from 120 leaves us 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.

On to step 12:
When dividing 50 by 23, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 12139.695652
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.

Let's proceed to step 13:
40 divided by 23 is 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 12139.6956521
If we subtract 23 from 40, we 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.

Advancing to step 14:
170 divided by 23 is 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 12139.69565217
Subtracting 161 from 170 leaves us 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.

The final outcome is 12139.69565217, with a leftover of 9e-09.
