2155 ÷ 23 
We want to figure out the number of times 2155 can be divided by 23.

Step 1:
If we divide 2 by 23, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 23

Step 2:
23 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 23

Let's proceed to step 3:
215 divided by 23 is 9 with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 207 from 215, we get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 23

Going ahead to step 4:
85 divided by 23 is 3 with a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 93.0
Subtract 69 from 85 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 5:
23 goes into 160 6 times with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 93.6
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.

Step 6:
23 can be fit into 220 9 times, resulting in a remainder of 13.
The next digit of our result is 9. 
Result so far: 93.69
Subtracting 207 from 220 leaves us 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.

Advancing to step 7:
23 goes into 130 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 93.695
If we take 115 away from 130, we end up 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.

Moving on to step 8:
150 divided by 23 is 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 93.6956
If we take 138 away from 150, we end up 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 9:
23 goes into 120 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 93.69565
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.

Let's proceed to step 10:
If we divide 50 by 23, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 93.695652
Subtract 46 from 50 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
The number 23 fits into 40 1 times, leaving a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 93.6956521
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.

On to step 12:
If we divide 170 by 23, we get 7 and a remainder of 9.
The next digit of our result is 7. 
Result so far: 93.69565217
If we take 161 away from 170, we end up 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 93.69565217, with a leftover of 9e-09.
