Let's divide 51791328 by 3
We want to figure out the number of times 51791328 can be divided by 3.

Going ahead to step 1:
5 divided by 3 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 3 from 5 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 3

Moving on to step 2:
21 divided by 3 is 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 17.0
Subtract 21 from 21 to get 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 3

On to step 3:
3 can be fit into 7 2 times, resulting in a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 172.0
Subtracting 6 from 7 leaves us with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 3

Moving on to step 4:
If we divide 19 by 3, we get 6 and a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 1726.0
The remainder is 1 after subtracting 18 from 19.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 3

Moving on to step 5:
3 can be fit into 11 3 times, resulting in a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 17263.0
If we take 9 away from 11, we end up with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 3

Step 6:
23 divided by 3 is 7 with a remainder of 2.
The next digit of our result is 7. 
Result so far: 172637.0
The remainder is 2 after subtracting 21 from 23.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 3

Moving on to step 7:
3 goes into 22 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 1726377.0
The remainder is 1 after subtracting 21 from 22.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 3

Moving on to step 8:
3 goes into 18 6 times with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 17263776.0
Subtracting 18 from 18 leaves us 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.

Step 9:
If we divide 0 by 3, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17263776.0
If we take 0 away from 0, we end up 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.

Let's proceed to step 10:
If we divide 0 by 3, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 17263776.0
The remainder is 0 after subtracting 0 from 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 17263776.0 with a remainder of 0.0.
