51359014 ÷ 30 
Let's see how many times 30 fits into 51359014.

Going ahead to step 1:
30 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 30

Going ahead to step 2:
30 can be fit into 51 1 times, resulting in a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 30 away from 51, we end up with 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 30

Let's proceed to step 3:
The number 30 fits into 213 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 17.0
Subtracting 210 from 213 leaves us with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 30

Let's proceed to step 4:
30 goes into 35 1 times with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 171.0
Deduct 30 from 35 and we're left with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 30

Going ahead to step 5:
30 goes into 59 1 times with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 1711.0
If we subtract 30 from 59, we get 29.
Include the next digit (0) from the dividend after 29, then repeat: 290 / 30

Let's proceed to step 6:
The number 30 fits into 290 9 times, leaving a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 17119.0
If we subtract 270 from 290, we get 20.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 30

Step 7:
201 divided by 30 is 6 with a remainder of 21.
Put 6 as the next digit of the answer. 
Result so far: 171196.0
If we subtract 180 from 201, we get 21.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 30

On to step 8:
The number 30 fits into 214 7 times, leaving a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 1711967.0
The remainder is 4 after subtracting 210 from 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
30 can be fit into 40 1 times, resulting in a remainder of 10.
The next digit of our result is 1. 
Result so far: 1711967.1
Subtracting 30 from 40 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
100 divided by 30 is 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 1711967.13
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
If we divide 100 by 30, we get 3 and a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 1711967.133
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 1711967.133 with a remainder of 0.001.
