We look at the division of 215102 by 60 
Let's see how many times 60 fits into 215102.

Step 1:
60 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 60

Going ahead to step 2:
21 divided by 60 is 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 60

Let's proceed to step 3:
When dividing 215 by 60, we get 3 with a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 180 from 215 to get 35.
Take the next digit (1) from the dividend and append it to 35, then repeat: 351 / 60

Let's proceed to step 4:
When dividing 351 by 60, we get 5 with a remainder of 51.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Subtract 300 from 351 to get 51.
Append the next digit (0) from the dividend to 51 and continue with: 510 / 60

Moving on to step 5:
510 divided by 60 is 8 with a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 358.0
Deduct 480 from 510 and we're left with 30.
Grab the next digit (2) from the dividend, add it to 30, then carry on: 302 / 60

Let's proceed to step 6:
302 divided by 60 is 5 with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 3585.0
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.

Moving on to step 7:
60 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 3585.0
Deduct 0 from 20 and we're left 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.

Going ahead to step 8:
60 goes into 200 3 times with a remainder of 20.
The next digit of our result is 3. 
Result so far: 3585.03
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.

On to step 9:
The number 60 fits into 200 3 times, leaving a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 3585.033
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 3585.033, with a leftover of 0.002.
