We divide 215948 by 3
We want to figure out the number of times 215948 can be divided by 3.

Let's proceed to step 1:
When dividing 2 by 3, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 3

Advancing to step 2:
21 divided by 3 is 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 21 from 21, we get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 3

Going ahead to step 3:
5 divided by 3 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 71.0
Deduct 3 from 5 and we're left with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 3

On to step 4:
3 can be fit into 29 9 times, resulting in a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 719.0
Deduct 27 from 29 and we're left with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 3

Moving on to step 5:
If we divide 24 by 3, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 7198.0
If we subtract 24 from 24, we get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 3

Let's proceed to step 6:
3 can be fit into 8 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 71982.0
Deduct 6 from 8 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
20 divided by 3 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 71982.6
Subtract 18 from 20 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 8:
If we divide 20 by 3, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 71982.66
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 71982.66, with a leftover of 0.002.
