Let's divide 642473 by 23
We want to divide 642473 by 23.

Let's proceed to step 1:
The number 23 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 23

Going ahead to step 2:
64 divided by 23 is 2 with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 46 from 64, we get 18.
Include the next digit (2) from the dividend after 18, then repeat: 182 / 23

On to step 3:
23 goes into 182 7 times with a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 27.0
The remainder is 21 after subtracting 161 from 182.
Grab the next digit (4) from the dividend, add it to 21, then carry on: 214 / 23

Advancing to step 4:
If we divide 214 by 23, we get 9 and a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 279.0
Subtract 207 from 214 to get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 23

Moving on to step 5:
If we divide 77 by 23, we get 3 and a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 2793.0
The remainder is 8 after subtracting 69 from 77.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 23

Advancing to step 6:
If we divide 83 by 23, we get 3 and a remainder of 14.
The next digit of our result is 3. 
Result so far: 27933.0
Subtract 69 from 83 to 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.

On to step 7:
When dividing 140 by 23, we get 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 27933.6
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.

Going ahead to step 8:
The number 23 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 27933.6
Subtracting 0 from 20 leaves us 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.

On to step 9:
200 divided by 23 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 27933.608
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.

On to step 10:
160 divided by 23 is 6 with a remainder of 22.
The next digit of our result is 6. 
Result so far: 27933.6086
Subtracting 138 from 160 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.

On to step 11:
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: 27933.60869
If we subtract 207 from 220, we get 13.
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 12:
23 can be fit into 130 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 27933.608695
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.

Moving on to step 13:
When dividing 150 by 23, we get 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 27933.6086956
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 14:
120 divided by 23 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 27933.60869565
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.

After the division, we end up with 27933.60869565 and a remainder of 5e-09.
