We divide 15751 by 30
We want to figure out the number of times 15751 can be divided by 30.

On to step 1:
30 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 30

Going ahead to step 2:
30 goes into 15 0 times with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 30

Advancing to step 3:
If we divide 157 by 30, we get 5 and a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 150 from 157 to get 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 30

Step 4:
75 divided by 30 is 2 with a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
Subtracting 60 from 75 leaves us with 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 30

Let's proceed to step 5:
30 goes into 151 5 times with a remainder of 1.
The next digit of our result is 5. 
Result so far: 525.0
If we take 150 away from 151, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 6:
The number 30 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 525.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
If we divide 100 by 30, we get 3 and a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 525.03
Subtracting 90 from 100 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.

Moving on to step 8:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 525.033
If we subtract 90 from 100, we get 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 outcome is 525.033, with a leftover of 0.001.
