315542 divided by 3 
We want to figure out the number of times 315542 can be divided by 3.

Advancing to step 1:
When dividing 3 by 3, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 0 after subtracting 3 from 3.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 3

Let's proceed to step 2:
3 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 1, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 3

Let's proceed to step 3:
The number 3 fits into 15 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 105.0
If we subtract 15 from 15, we get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 3

On to step 4:
If we divide 5 by 3, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1051.0
If we take 3 away from 5, we end up with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 3

Moving on to step 5:
The number 3 fits into 24 8 times, leaving a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 10518.0
If we subtract 24 from 24, we get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 3

Let's proceed to step 6:
3 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 105180.0
Deduct 0 from 2 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.

On to step 7:
3 can be fit into 20 6 times, resulting in a remainder of 2.
The next digit of our result is 6. 
Result so far: 105180.6
Deduct 18 from 20 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.

On to step 8:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 105180.66
Deduct 18 from 20 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.

The quotient of the division is 105180.66, and the remainder is 0.002.
