We look at the division of 215453 by 6 
Let's see how many times 6 fits into 215453.

On to step 1:
6 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 6

On to step 2:
The number 6 fits into 21 3 times, leaving a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 18 away from 21, we end up with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 6

On to step 3:
35 divided by 6 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 35.0
If we subtract 30 from 35, we get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 6

Going ahead to step 4:
When dividing 54 by 6, we get 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 359.0
Subtracting 54 from 54 leaves us with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 6

Let's proceed to step 5:
6 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 3590.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 6

Let's proceed to step 6:
The number 6 fits into 53 8 times, leaving a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 35908.0
Subtracting 48 from 53 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
The number 6 fits into 50 8 times, leaving a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 35908.8
Subtracting 48 from 50 leaves us 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.

Let's proceed to step 8:
The number 6 fits into 20 3 times, leaving a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 35908.83
Subtracting 18 from 20 leaves us 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.

Let's proceed to step 9:
The number 6 fits into 20 3 times, leaving a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 35908.833
If we subtract 18 from 20, we 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.

After the division, we end up with 35908.833 and a remainder of 0.0002.
