645218 divided by 23 
We want to divide 645218 by 23.

Step 1:
If we divide 6 by 23, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 23

Going ahead to step 2:
23 goes into 64 2 times with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 46 from 64 and we're left with 18.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 23

Moving on to step 3:
23 can be fit into 185 8 times, resulting in a remainder of 1.
The next digit of our result is 8. 
Result so far: 28.0
Deduct 184 from 185 and we're left with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 23

Going ahead to step 4:
The number 23 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 280.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 23

Moving on to step 5:
The number 23 fits into 121 5 times, leaving a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 2805.0
If we take 115 away from 121, we end up with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 23

Step 6:
68 divided by 23 is 2 with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 28052.0
Subtracting 46 from 68 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.

Let's proceed to step 7:
220 divided by 23 is 9 with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 28052.9
If we take 207 away from 220, we end up 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 8:
23 goes into 130 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 28052.95
If we subtract 115 from 130, we get 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 9:
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: 28052.956
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.

Let's proceed to step 10:
When dividing 120 by 23, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 28052.9565
Subtracting 115 from 120 leaves us 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.

On to step 11:
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: 28052.95652
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.

Advancing to step 12:
The number 23 fits into 40 1 times, leaving a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 28052.956521
Subtract 23 from 40 to get 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 13:
23 can be fit into 170 7 times, resulting in a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 28052.9565217
Deduct 161 from 170 and we're left 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.

Advancing to step 14:
90 divided by 23 is 3 with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 28052.95652173
If we take 69 away from 90, we end up with 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 28052.95652173, and the remainder is 2.1e-08.
