291987 ÷ 23 
We're looking to find how many times 23 goes into 291987.

Moving on to step 1:
The number 23 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 23

Going ahead to step 2:
When dividing 29 by 23, we get 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 6 after subtracting 23 from 29.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 23

Advancing to step 3:
If we divide 61 by 23, we get 2 and a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 46 from 61 and we're left with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 23

Going ahead to step 4:
If we divide 159 by 23, we get 6 and a remainder of 21.
Use 6 as the next digit of our solution. 
Result so far: 126.0
Deduct 138 from 159 and we're left with 21.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 23

Moving on to step 5:
The number 23 fits into 218 9 times, leaving a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 1269.0
Subtracting 207 from 218 leaves us with 11.
Include the next digit (7) from the dividend after 11, then repeat: 117 / 23

Step 6:
23 goes into 117 5 times with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 12695.0
If we subtract 115 from 117, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to 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: 12695.0
Deduct 0 from 20 and we're left 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 8:
When dividing 200 by 23, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 12695.08
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.

Moving on to step 9:
The number 23 fits into 160 6 times, leaving a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 12695.086
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.

On to step 10:
23 goes into 220 9 times with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 12695.0869
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.

Going ahead to step 11:
23 goes into 130 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 12695.08695
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.

On to step 12:
When dividing 150 by 23, we get 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 12695.086956
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.

Let's proceed to step 13:
If we divide 120 by 23, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 12695.0869565
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.

Going ahead to step 14:
23 can be fit into 50 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 12695.08695652
Deduct 46 from 50 and we're left 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 quotient of the division is 12695.08695652, and the remainder is 4e-09.
