Let's divide 553820 by 3
We're looking to find how many times 3 goes into 553820.

Step 1:
When dividing 5 by 3, we get 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 3 from 5 to get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 3

Let's proceed to step 2:
25 divided by 3 is 8 with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we subtract 24 from 25, we get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 3

On to step 3:
The number 3 fits into 13 4 times, leaving a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 184.0
The remainder is 1 after subtracting 12 from 13.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 3

Moving on to step 4:
3 can be fit into 18 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 1846.0
Subtract 18 from 18 to get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 3

Advancing to step 5:
3 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 18460.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 3

Advancing to step 6:
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: 184606.0
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.

Let's proceed to step 7:
When dividing 20 by 3, we get 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 184606.6
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.

On to step 8:
20 divided by 3 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 184606.66
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 184606.66, with a leftover of 0.002.
