We divide 360632 by 21
Let's see how many times 21 fits into 360632.

On to step 1:
21 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 21

Step 2:
The number 21 fits into 36 1 times, leaving a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 21 from 36, we get 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 21

On to step 3:
150 divided by 21 is 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Deduct 147 from 150 and we're left with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 21

Advancing to step 4:
36 divided by 21 is 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 171.0
Subtract 21 from 36 to get 15.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 21

Advancing to step 5:
21 goes into 153 7 times with a remainder of 6.
The next digit of our result is 7. 
Result so far: 1717.0
If we subtract 147 from 153, we get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 21

Going ahead to step 6:
When dividing 62 by 21, we get 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 17172.0
Subtract 42 from 62 to 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.

Advancing to step 7:
21 can be fit into 200 9 times, resulting in a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 17172.9
If we take 189 away from 200, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 8:
21 can be fit into 110 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 17172.95
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.

On to step 9:
21 can be fit into 50 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 17172.952
Subtract 42 from 50 to 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.

Let's proceed to step 10:
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: 17172.9523
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 11:
21 goes into 170 8 times with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 17172.95238
Deduct 168 from 170 and we're left 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.

Advancing to step 12:
When dividing 20 by 21, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 17172.95238
Subtracting 0 from 20 leaves us 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.

Advancing to step 13:
If we divide 200 by 21, we get 9 and a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 17172.9523809
Subtract 189 from 200 to 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.

Step 14:
110 divided by 21 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 17172.95238095
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.

The quotient of the division is 17172.95238095, and the remainder is 5e-09.
