315951 ÷ 30 
We want to figure out the number of times 315951 can be divided by 30.

Going ahead to step 1:
3 divided by 30 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 30

Moving on to step 2:
30 can be fit into 31 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 30 from 31 to get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 30

On to step 3:
30 can be fit into 15 0 times, resulting in a remainder of 15.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 15 after subtracting 0 from 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 30

Moving on to step 4:
When dividing 159 by 30, we get 5 with a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 105.0
If we subtract 150 from 159, we get 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 30

Let's proceed to step 5:
30 can be fit into 95 3 times, resulting in a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 1053.0
Deduct 90 from 95 and we're left with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 30

Advancing to step 6:
The number 30 fits into 51 1 times, leaving a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 10531.0
If we subtract 30 from 51, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
210 divided by 30 is 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 10531.7
If we subtract 210 from 210, 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.

Going ahead to step 8:
The number 30 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 10531.7
Subtracting 0 from 0 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.

Let's proceed to step 9:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10531.7
Subtracting 0 from 0 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.

The final result is 10531.7 with a remainder of 0.0.
