We look at the division of 584643 by 23 
We want to divide 584643 by 23.

Going ahead to step 1:
23 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 23

On to step 2:
23 can be fit into 58 2 times, resulting in a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 46 from 58 to get 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 23

Moving on to step 3:
If we divide 124 by 23, we get 5 and a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtract 115 from 124 to get 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 23

Advancing to step 4:
When dividing 96 by 23, we get 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 254.0
Subtracting 92 from 96 leaves us with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 23

On to step 5:
23 goes into 44 1 times with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 2541.0
Subtracting 23 from 44 leaves us with 21.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 23

Step 6:
If we divide 213 by 23, we get 9 and a remainder of 6.
The next digit of our result is 9. 
Result so far: 25419.0
Subtracting 207 from 213 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
23 can be fit into 60 2 times, resulting in a remainder of 14.
The next digit of our result is 2. 
Result so far: 25419.2
The remainder is 14 after subtracting 46 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
The number 23 fits into 140 6 times, leaving a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 25419.26
If we take 138 away from 140, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
23 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 25419.26
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
When dividing 200 by 23, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 25419.2608
Deduct 184 from 200 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
23 can be fit into 160 6 times, resulting in a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 25419.26086
The remainder is 22 after subtracting 138 from 160.
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 12:
The number 23 fits into 220 9 times, leaving a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 25419.260869
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.

Moving on to step 13:
If we divide 130 by 23, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 25419.2608695
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.

Advancing to step 14:
If we divide 150 by 23, we get 6 and a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 25419.26086956
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.

The final outcome is 25419.26086956, with a leftover of 1.2e-08.
