818140 ÷ 23 
We're looking to find how many times 23 goes into 818140.

Going ahead 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.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 23

On to step 2:
23 goes into 81 3 times with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 69 from 81, we get 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 23

Let's proceed to step 3:
23 goes into 128 5 times with a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 35.0
The remainder is 13 after subtracting 115 from 128.
Fetch the next digit (1) from the dividend, attach it to 13 and continue: 131 / 23

Advancing to step 4:
131 divided by 23 is 5 with a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 355.0
If we take 115 away from 131, we end up with 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 23

Let's proceed to step 5:
23 can be fit into 164 7 times, resulting in a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 3557.0
Subtracting 161 from 164 leaves us with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 23

Let's proceed to step 6:
23 can be fit into 30 1 times, resulting in a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 35571.0
Subtracting 23 from 30 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
23 goes into 70 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 35571.3
The remainder is 1 after subtracting 69 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 8:
When dividing 10 by 23, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 35571.3
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
100 divided by 23 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 35571.304
If we take 92 away from 100, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
23 can be fit into 80 3 times, resulting in a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 35571.3043
If we subtract 69 from 80, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 11:
23 can be fit into 110 4 times, resulting in a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 35571.30434
Deduct 92 from 110 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 12:
When dividing 180 by 23, we get 7 with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 35571.304347
Deduct 161 from 180 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 13:
190 divided by 23 is 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 35571.3043478
If we subtract 184 from 190, 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.

Going ahead to step 14:
60 divided by 23 is 2 with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 35571.30434782
If we subtract 46 from 60, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 35571.30434782, with a leftover of 1.4e-08.
