362066 divided by 21 
We're looking to find how many times 21 goes into 362066.

On to step 1:
3 divided by 21 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 21

Let's proceed to step 2:
If we divide 36 by 21, we get 1 and a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 21 from 36 leaves us with 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 21

Advancing to step 3:
152 divided by 21 is 7 with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 147 from 152 leaves us with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 21

Let's proceed to step 4:
The number 21 fits into 50 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 172.0
If we subtract 42 from 50, we get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 21

Going ahead to step 5:
When dividing 86 by 21, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 1724.0
If we take 84 away from 86, we end up with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 21

Moving on to step 6:
21 can be fit into 26 1 times, resulting in a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 17241.0
If we take 21 away from 26, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
50 divided by 21 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 17241.2
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 8:
21 can be fit into 80 3 times, resulting in a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 17241.23
Deduct 63 from 80 and we're left 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.

On to step 9:
When dividing 170 by 21, we get 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 17241.238
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.

Let's proceed to step 10:
21 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 17241.238
If we subtract 0 from 20, we get 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 11:
The number 21 fits into 200 9 times, leaving a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 17241.23809
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.

Advancing to step 12:
21 can be fit into 110 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 17241.238095
If we take 105 away from 110, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 13:
21 goes into 50 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 17241.2380952
If we subtract 42 from 50, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 14:
21 goes into 80 3 times with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 17241.23809523
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.

The final result is 17241.23809523 with a remainder of 1.7e-08.
