We divide 551348 by 3
We want to figure out the number of times 551348 can be divided by 3.

Going ahead to step 1:
3 goes into 5 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 3 from 5 leaves us with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 3

Step 2:
3 goes into 25 8 times with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we subtract 24 from 25, we get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 3

Let's proceed to step 3:
When dividing 11 by 3, we get 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 183.0
Deduct 9 from 11 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 3

Going ahead to step 4:
3 can be fit into 23 7 times, resulting in a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 1837.0
Subtract 21 from 23 to get 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 3

On to step 5:
3 can be fit into 24 8 times, resulting in a remainder of 0.
The next digit of our result is 8. 
Result so far: 18378.0
Subtract 24 from 24 to get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 3

Advancing to step 6:
If we divide 8 by 3, we get 2 and a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 183782.0
The remainder is 2 after subtracting 6 from 8.
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 7:
If we divide 20 by 3, we get 6 and a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 183782.6
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.

Advancing to step 8:
20 divided by 3 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 183782.66
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.

The final outcome is 183782.66, with a leftover of 0.002.
