87997 ÷ 23 
Our goal is to divide 87997 by 23.

Moving on to step 1:
23 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 23

Advancing to step 2:
23 goes into 87 3 times with a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 69 away from 87, we end up with 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 23

Step 3:
If we divide 189 by 23, we get 8 and a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Subtracting 184 from 189 leaves us with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 23

Step 4:
If we divide 59 by 23, we get 2 and a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 382.0
Subtracting 46 from 59 leaves us with 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 23

Advancing to step 5:
When dividing 137 by 23, we get 5 with a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 3825.0
If we subtract 115 from 137, we 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.

Going ahead to step 6:
If we divide 220 by 23, we get 9 and a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 3825.9
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.

On to step 7:
If we divide 130 by 23, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 3825.95
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 8:
The number 23 fits into 150 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 3825.956
The remainder is 12 after subtracting 138 from 150.
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 9:
120 divided by 23 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 3825.9565
If we subtract 115 from 120, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
When dividing 50 by 23, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 3825.95652
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 11:
The number 23 fits into 40 1 times, leaving a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 3825.956521
If we take 23 away from 40, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 12:
When dividing 170 by 23, we get 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 3825.9565217
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.

Moving on to step 13:
23 can be fit into 90 3 times, resulting in a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 3825.95652173
Subtract 69 from 90 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final result is 3825.95652173 with a remainder of 2.1e-08.
