54404586 divided by 3 
Let's see how many times 3 fits into 54404586.

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
Subtract 3 from 5 to get 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 3

Advancing to step 2:
The number 3 fits into 24 8 times, leaving a remainder of 0.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 24 from 24 and we're left with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 3

Step 3:
4 divided by 3 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 181.0
Deduct 3 from 4 and we're left with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 3

Let's proceed to step 4:
10 divided by 3 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 1813.0
Deduct 9 from 10 and we're left with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 3

Advancing to step 5:
3 goes into 14 4 times with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 18134.0
Deduct 12 from 14 and we're left with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 3

On to step 6:
3 can be fit into 25 8 times, resulting in a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 181348.0
If we subtract 24 from 25, we get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 3

Moving on to step 7:
If we divide 18 by 3, we get 6 and a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 1813486.0
Deduct 18 from 18 and we're left with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 3

On to step 8:
If we divide 6 by 3, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 18134862.0
Deduct 6 from 6 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
The number 3 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 18134862.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
When dividing 0 by 3, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18134862.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 18134862.0 with a remainder of 0.0.
