Let's divide 890324 by 21
We want to divide 890324 by 21.

Going ahead to step 1:
21 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 21

Moving on to step 2:
When dividing 89 by 21, we get 4 with a remainder of 5.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 5 after subtracting 84 from 89.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 21

On to step 3:
The number 21 fits into 50 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Subtracting 42 from 50 leaves us with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 21

Going ahead to step 4:
21 goes into 83 3 times with a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 423.0
Deduct 63 from 83 and we're left with 20.
Include the next digit (2) from the dividend after 20, then repeat: 202 / 21

Step 5:
When dividing 202 by 21, we get 9 with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 4239.0
If we take 189 away from 202, we end up with 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 21

Moving on to step 6:
When dividing 134 by 21, we get 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 42396.0
Subtracting 126 from 134 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
21 can be fit into 80 3 times, resulting in a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 42396.3
Subtract 63 from 80 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 8:
170 divided by 21 is 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 42396.38
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
If we divide 20 by 21, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 42396.38
Deduct 0 from 20 and we're left 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.

Let's proceed to step 10:
21 goes into 200 9 times with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 42396.3809
If we subtract 189 from 200, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 11:
110 divided by 21 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 42396.38095
If we subtract 105 from 110, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 12:
The number 21 fits into 50 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 42396.380952
If we take 42 away from 50, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
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: 42396.3809523
If we take 63 away from 80, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 14:
170 divided by 21 is 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 42396.38095238
Subtracting 168 from 170 leaves us 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.

The final result is 42396.38095238 with a remainder of 2e-09.
