Let's divide 841893 by 40
Let's see how many times 40 fits into 841893.

Advancing to step 1:
If we divide 8 by 40, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 40

Going ahead to 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.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 40

Step 3:
The number 40 fits into 41 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtract 40 from 41 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 40

Advancing to step 4:
18 divided by 40 is 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 210.0
Deduct 0 from 18 and we're left with 18.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 40

On to step 5:
40 can be fit into 189 4 times, resulting in a remainder of 29.
The next digit of our result is 4. 
Result so far: 2104.0
Deduct 160 from 189 and we're left with 29.
Take the next digit (3) from the dividend and append it to 29, then repeat: 293 / 40

Moving on to step 6:
When dividing 293 by 40, we get 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 21047.0
Subtracting 280 from 293 leaves us 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.

Step 7:
130 divided by 40 is 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 21047.3
If we subtract 120 from 130, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
If we divide 100 by 40, we get 2 and a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 21047.32
Subtracting 80 from 100 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.

Advancing to step 9:
40 can be fit into 200 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 21047.325
If we subtract 200 from 200, 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.

On to step 10:
If we divide 0 by 40, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 21047.325
Subtracting 0 from 0 leaves us 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.

Moving on to step 11:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 21047.325
Deduct 0 from 0 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.

After the division, we end up with 21047.325 and a remainder of 0.0.
