We divide 561413 by 3
We're looking to find how many times 3 goes into 561413.

On to step 1:
When dividing 5 by 3, we get 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 3 from 5 leaves us with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 3

Advancing to step 2:
If we divide 26 by 3, we get 8 and a remainder of 2.
The next digit of our result is 8. 
Result so far: 18.0
The remainder is 2 after subtracting 24 from 26.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 3

Step 3:
21 divided by 3 is 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 187.0
Deduct 21 from 21 and we're left with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 3

Step 4:
If we divide 4 by 3, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1871.0
Deduct 3 from 4 and we're left with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 3

Moving on to step 5:
3 goes into 11 3 times with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 18713.0
Subtracting 9 from 11 leaves us with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 3

Step 6:
If we divide 23 by 3, we get 7 and a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 187137.0
Subtracting 21 from 23 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.

Advancing to step 7:
20 divided by 3 is 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 187137.6
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.

Advancing to step 8:
If we divide 20 by 3, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 187137.66
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 187137.66 and a remainder of 0.002.
