21902 divided by 60 
Let's see how many times 60 fits into 21902.

Moving on to step 1:
If we divide 2 by 60, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 60

Let's proceed to step 2:
The number 60 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Bring next digit (9) of the dividend behind the 21 and repeat the process: 219 / 60

Let's proceed to step 3:
60 can be fit into 219 3 times, resulting in a remainder of 39.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 180 from 219 leaves us with 39.
Take the next digit (0) from the dividend and append it to 39, then repeat: 390 / 60

Going ahead to step 4:
The number 60 fits into 390 6 times, leaving a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 36.0
If we take 360 away from 390, we end up with 30.
Fetch the next digit (2) from the dividend, attach it to 30 and continue: 302 / 60

Advancing to step 5:
302 divided by 60 is 5 with a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 365.0
Subtract 300 from 302 to get 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 6:
60 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 365.0
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.

Let's proceed to step 7:
200 divided by 60 is 3 with a remainder of 20.
The next digit of our result is 3. 
Result so far: 365.03
Subtract 180 from 200 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.

Step 8:
60 can be fit into 200 3 times, resulting in a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 365.033
If we subtract 180 from 200, 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.

The final outcome is 365.033, with a leftover of 0.002.
