Let's divide 800044 by 21
We're looking to find how many times 21 goes into 800044.

Step 1:
When dividing 8 by 21, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 21

Let's proceed to step 2:
When dividing 80 by 21, we get 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 63 away from 80, we end up with 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 21

On to step 3:
21 can be fit into 170 8 times, resulting in a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Subtract 168 from 170 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 21

Advancing to step 4:
21 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 380.0
Subtract 0 from 20 to get 20.
Fetch the next digit (4) from the dividend, attach it to 20 and continue: 204 / 21

Moving on to step 5:
204 divided by 21 is 9 with a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 3809.0
The remainder is 15 after subtracting 189 from 204.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 21

Advancing to step 6:
The number 21 fits into 154 7 times, leaving a remainder of 7.
The next digit of our result is 7. 
Result so far: 38097.0
Subtract 147 from 154 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
If we divide 70 by 21, we get 3 and a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 38097.3
Deduct 63 from 70 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 8:
70 divided by 21 is 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 38097.33
Subtracting 63 from 70 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final result is 38097.33 with a remainder of 0.007.
