We divide 843623 by 40
We want to figure out the number of times 843623 can be divided by 40.

Advancing to step 1:
40 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 40

Step 2:
If we divide 84 by 40, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 80 from 84 to get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 40

Going ahead to step 3:
If we divide 43 by 40, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtracting 40 from 43 leaves us with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 40

On to step 4:
36 divided by 40 is 0 with a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 210.0
Subtracting 0 from 36 leaves us with 36.
Include the next digit (2) from the dividend after 36, then repeat: 362 / 40

Going ahead to step 5:
40 goes into 362 9 times with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 2109.0
The remainder is 2 after subtracting 360 from 362.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 40

Step 6:
The number 40 fits into 23 0 times, leaving a remainder of 23.
The next digit of our result is 0. 
Result so far: 21090.0
If we take 0 away from 23, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 7:
40 goes into 230 5 times with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 21090.5
If we subtract 200 from 230, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
300 divided by 40 is 7 with a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 21090.57
If we take 280 away from 300, 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.

Step 9:
If we divide 200 by 40, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 21090.575
Deduct 200 from 200 and we're left 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.

Step 10:
The number 40 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 21090.575
If we take 0 away from 0, 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 11:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 21090.575
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 21090.575, and the remainder is 0.0.
