We're dividing 364889 by 21 
Our goal is to divide 364889 by 21.

Let's proceed to step 1:
3 divided by 21 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 21

On to step 2:
If we divide 36 by 21, we get 1 and a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 21 from 36 and we're left with 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 21

Let's proceed to step 3:
154 divided by 21 is 7 with a remainder of 7.
The next digit of our result is 7. 
Result so far: 17.0
Subtract 147 from 154 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 21

Let's proceed to step 4:
78 divided by 21 is 3 with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 173.0
Deduct 63 from 78 and we're left with 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 21

Let's proceed to step 5:
When dividing 158 by 21, we get 7 with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 1737.0
Deduct 147 from 158 and we're left with 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 21

On to step 6:
119 divided by 21 is 5 with a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 17375.0
If we subtract 105 from 119, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
The number 21 fits into 140 6 times, leaving a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 17375.6
Subtract 126 from 140 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
140 divided by 21 is 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 17375.66
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 17375.66 with a remaining 0.014.
