871943 divided by 23 
Our goal is to divide 871943 by 23.

On to step 1:
If we divide 8 by 23, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 23

On to step 2:
23 can be fit into 87 3 times, resulting in a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 69 from 87 and we're left with 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 23

Let's proceed to step 3:
23 can be fit into 181 7 times, resulting in a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 37.0
If we subtract 161 from 181, we get 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 23

Moving on to step 4:
209 divided by 23 is 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 379.0
Subtract 207 from 209 to get 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 23

Going ahead to step 5:
23 can be fit into 24 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 3791.0
Subtracting 23 from 24 leaves us with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 23

Moving on to step 6:
23 goes into 13 0 times with a remainder of 13.
The next digit of our result is 0. 
Result so far: 37910.0
Deduct 0 from 13 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 7:
23 goes into 130 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 37910.5
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.

On to step 8:
150 divided by 23 is 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 37910.56
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.

Moving on to step 9:
If we divide 120 by 23, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 37910.565
Deduct 115 from 120 and we're left 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.

Moving on to step 10:
23 goes into 50 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 37910.5652
The remainder is 4 after subtracting 46 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
23 can be fit into 40 1 times, resulting in a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 37910.56521
Subtracting 23 from 40 leaves us 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.

Going ahead to step 12:
170 divided by 23 is 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 37910.565217
Subtract 161 from 170 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 13:
When dividing 90 by 23, we get 3 with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 37910.5652173
If we subtract 69 from 90, we 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.

Going ahead to step 14:
210 divided by 23 is 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 37910.56521739
Subtracting 207 from 210 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 37910.56521739 with a remainder of 3e-09.
