We look at the division of 311931 by 30 
Our goal is to divide 311931 by 30.

Step 1:
30 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 30

On to step 2:
If we divide 31 by 30, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 30 away from 31, we end up with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 30

Step 3:
30 can be fit into 11 0 times, resulting in a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 11 and we're left with 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 30

Moving on to step 4:
If we divide 119 by 30, we get 3 and a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 103.0
Deduct 90 from 119 and we're left with 29.
Grab the next digit (3) from the dividend, add it to 29, then carry on: 293 / 30

On to step 5:
If we divide 293 by 30, we get 9 and a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 1039.0
Deduct 270 from 293 and we're left with 23.
Take the next digit (1) from the dividend and append it to 23, then repeat: 231 / 30

Advancing to step 6:
When dividing 231 by 30, we get 7 with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 10397.0
The remainder is 21 after subtracting 210 from 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
The number 30 fits into 210 7 times, leaving a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 10397.7
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.

On to step 8:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10397.7
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.

On to step 9:
0 divided by 30 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10397.7
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.

Our division results in 10397.7 with a remaining 0.0.
