21538 divided by 60 
Let's see how many times 60 fits into 21538.

Let's proceed to step 1:
60 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 60

Advancing to step 2:
If we divide 21 by 60, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 60

Advancing to step 3:
215 divided by 60 is 3 with a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 180 away from 215, we end up with 35.
Append the next digit (3) from the dividend to 35 and continue with: 353 / 60

Moving on to step 4:
353 divided by 60 is 5 with a remainder of 53.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Deduct 300 from 353 and we're left with 53.
Append the next digit (8) from the dividend to 53 and continue with: 538 / 60

Moving on to step 5:
60 can be fit into 538 8 times, resulting in a remainder of 58.
The next digit of our result is 8. 
Result so far: 358.0
If we subtract 480 from 538, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 6:
When dividing 580 by 60, we get 9 with a remainder of 40.
Use 9 as the next digit of our solution. 
Result so far: 358.9
If we subtract 540 from 580, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 7:
When dividing 400 by 60, we get 6 with a remainder of 40.
The next digit of our result is 6. 
Result so far: 358.96
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
60 goes into 400 6 times with a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 358.966
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 358.966, and the remainder is 0.004.
