We look at the division of 58365 by 21 
We're looking to find how many times 21 goes into 58365.

Let's proceed to step 1:
If we divide 5 by 21, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 21

Advancing to step 2:
21 can be fit into 58 2 times, resulting in a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 42 away from 58, we end up with 16.
Bring next digit (3) of the dividend behind the 16 and repeat the process: 163 / 21

Step 3:
If we divide 163 by 21, we get 7 and a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 27.0
Subtracting 147 from 163 leaves us with 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 21

Going ahead to step 4:
The number 21 fits into 166 7 times, leaving a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 277.0
The remainder is 19 after subtracting 147 from 166.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 21

Moving on to step 5:
The number 21 fits into 195 9 times, leaving a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 2779.0
The remainder is 6 after subtracting 189 from 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 6:
21 goes into 60 2 times with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 2779.2
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
When dividing 180 by 21, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 2779.28
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 8:
21 can be fit into 120 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 2779.285
If we subtract 105 from 120, we 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.

On to step 9:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 2779.2857
Subtract 147 from 150 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 10:
21 can be fit into 30 1 times, resulting in a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 2779.28571
If we take 21 away from 30, we end up 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.

Advancing to step 11:
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: 2779.285714
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 12:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 2779.2857142
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 13:
When dividing 180 by 21, we get 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 2779.28571428
If we take 168 away from 180, 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.

The final outcome is 2779.28571428, with a leftover of 1.2e-08.
