Let's divide 345857 by 23
Let's see how many times 23 fits into 345857.

On to step 1:
The number 23 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 23

Going ahead to step 2:
When dividing 34 by 23, we get 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 23 from 34 to get 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 23

Going ahead to step 3:
The number 23 fits into 115 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 115 from 115, we get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 23

Going ahead to step 4:
If we divide 8 by 23, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 150.0
Subtract 0 from 8 to get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 23

Advancing to step 5:
When dividing 85 by 23, we get 3 with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 1503.0
Subtracting 69 from 85 leaves us with 16.
Take the next digit (7) from the dividend and append it to 16, then repeat: 167 / 23

Step 6:
23 goes into 167 7 times with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 15037.0
If we subtract 161 from 167, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
23 goes into 60 2 times with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 15037.2
The remainder is 14 after subtracting 46 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
If we divide 140 by 23, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 15037.26
Subtracting 138 from 140 leaves us 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.

Advancing to step 9:
23 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 15037.26
Subtracting 0 from 20 leaves us with 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 10:
When dividing 200 by 23, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 15037.2608
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.

Moving on to step 11:
160 divided by 23 is 6 with a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 15037.26086
Subtract 138 from 160 to get 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 12:
23 goes into 220 9 times with a remainder of 13.
The next digit of our result is 9. 
Result so far: 15037.260869
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 13:
23 goes into 130 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 15037.2608695
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.

Step 14:
23 goes into 150 6 times with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 15037.26086956
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.

After the division, we end up with 15037.26086956 and a remainder of 1.2e-08.
