367365 divided by 21 
We want to figure out the number of times 367365 can be divided by 21.

Step 1:
3 divided by 21 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 21

Advancing to step 2:
21 goes into 36 1 times with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 21 from 36 leaves us with 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 21

Advancing to step 3:
The number 21 fits into 157 7 times, leaving a remainder of 10.
The next digit of our result is 7. 
Result so far: 17.0
If we subtract 147 from 157, we get 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 21

Step 4:
21 goes into 103 4 times with a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 174.0
The remainder is 19 after subtracting 84 from 103.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 21

Moving on to step 5:
21 can be fit into 196 9 times, resulting in a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 1749.0
Deduct 189 from 196 and we're left with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 21

On to step 6:
When dividing 75 by 21, we get 3 with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 17493.0
If we take 63 away from 75, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
When dividing 120 by 21, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 17493.5
Subtract 105 from 120 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
21 can be fit into 150 7 times, resulting in a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 17493.57
Subtracting 147 from 150 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
21 can be fit into 30 1 times, resulting in a remainder of 9.
The next digit of our result is 1. 
Result so far: 17493.571
Deduct 21 from 30 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 10:
The number 21 fits into 90 4 times, leaving a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 17493.5714
Subtracting 84 from 90 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 11:
21 goes into 60 2 times with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 17493.57142
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 12:
180 divided by 21 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 17493.571428
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
21 goes into 120 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 17493.5714285
If we take 105 away from 120, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 14:
When dividing 150 by 21, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 17493.57142857
If we take 147 away from 150, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Our division results in 17493.57142857 with a remaining 3e-09.
