18215470 divided by 23 
Let's see how many times 23 fits into 18215470.

Going ahead to step 1:
If we divide 1 by 23, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 23

Moving on to step 2:
If we divide 18 by 23, we get 0 and a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Include the next digit (2) from the dividend after 18, then repeat: 182 / 23

Step 3:
When dividing 182 by 23, we get 7 with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 161 from 182, we get 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 23

Going ahead to step 4:
If we divide 211 by 23, we get 9 and a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 79.0
Deduct 207 from 211 and we're left with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 23

On to step 5:
If we divide 45 by 23, we get 1 and a remainder of 22.
The next digit of our result is 1. 
Result so far: 791.0
Subtract 23 from 45 to get 22.
Include the next digit (4) from the dividend after 22, then repeat: 224 / 23

Step 6:
When dividing 224 by 23, we get 9 with a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 7919.0
Deduct 207 from 224 and we're left with 17.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 23

Step 7:
When dividing 177 by 23, we get 7 with a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 79197.0
Subtracting 161 from 177 leaves us with 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 23

On to step 8:
23 can be fit into 160 6 times, resulting in a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 791976.0
If we take 138 away from 160, we end up 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.

Moving on to step 9:
When dividing 220 by 23, we get 9 with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 791976.9
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 10:
When dividing 130 by 23, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 791976.95
Subtracting 115 from 130 leaves us 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.

Going ahead to step 11:
23 can be fit into 150 6 times, resulting in a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 791976.956
Deduct 138 from 150 and we're left 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 12:
If we divide 120 by 23, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 791976.9565
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.

Let's proceed to step 13:
The number 23 fits into 50 2 times, leaving a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 791976.95652
If we subtract 46 from 50, we 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 14:
40 divided by 23 is 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 791976.956521
The remainder is 17 after subtracting 23 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 15:
The number 23 fits into 170 7 times, leaving a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 791976.9565217
If we subtract 161 from 170, we 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.

Going ahead to step 16:
If we divide 90 by 23, we get 3 and a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 791976.95652173
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 quotient of the division is 791976.95652173, and the remainder is 2.1e-08.
