360775 divided by 21 
We want to figure out the number of times 360775 can be divided by 21.

On to step 1:
21 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 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
If we subtract 21 from 36, we get 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 21

Let's proceed to step 3:
When dividing 150 by 21, we get 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
The remainder is 3 after subtracting 147 from 150.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 21

Going ahead to step 4:
37 divided by 21 is 1 with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 171.0
Deduct 21 from 37 and we're left with 16.
Include the next digit (7) from the dividend after 16, then repeat: 167 / 21

Let's proceed to step 5:
21 can be fit into 167 7 times, resulting in a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 1717.0
Subtracting 147 from 167 leaves us with 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 21

Going ahead to step 6:
When dividing 205 by 21, we get 9 with a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 17179.0
Subtract 189 from 205 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
21 can be fit into 160 7 times, resulting in a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 17179.7
If we subtract 147 from 160, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 8:
21 goes into 130 6 times with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 17179.76
Subtract 126 from 130 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
40 divided by 21 is 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 17179.761
If we take 21 away from 40, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 10:
21 goes into 190 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 17179.7619
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 11:
10 divided by 21 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 17179.7619
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
When dividing 100 by 21, we get 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 17179.761904
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
21 can be fit into 160 7 times, resulting in a remainder of 13.
The next digit of our result is 7. 
Result so far: 17179.7619047
If we take 147 away from 160, we end up 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.

On to step 14:
If we divide 130 by 21, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 17179.76190476
Subtracting 126 from 130 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 17179.76190476 with a balance of 4e-09.
