We divide 2643 by 4
We want to divide 2643 by 4.

Let's proceed to step 1:
4 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 4

Moving on to step 2:
The number 4 fits into 26 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 24 from 26, we get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 4

Moving on to step 3:
When dividing 24 by 4, we get 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
If we take 24 away from 24, we end up with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 4

Going ahead to step 4:
When dividing 3 by 4, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 660.0
Subtract 0 from 3 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 5:
4 can be fit into 30 7 times, resulting in a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 660.7
If we take 28 away from 30, 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.

On to step 6:
4 goes into 20 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 660.75
If we take 20 away from 20, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
When dividing 0 by 4, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 660.75
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
When dividing 0 by 4, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 660.75
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 660.75 with a remaining 0.0.
