Let's divide 31711872 by 30
We want to figure out the number of times 31711872 can be divided by 30.

On to step 1:
30 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 30

Moving on to step 2:
If we divide 31 by 30, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 1 after subtracting 30 from 31.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 30

Advancing to step 3:
The number 30 fits into 17 0 times, leaving a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 17 after subtracting 0 from 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 30

Let's proceed to step 4:
The number 30 fits into 171 5 times, leaving a remainder of 21.
Record the quotient 5 as the next digit in the result. 
Result so far: 105.0
Subtracting 150 from 171 leaves us with 21.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 30

Moving on to step 5:
30 goes into 211 7 times with a remainder of 1.
The next digit of our result is 7. 
Result so far: 1057.0
If we subtract 210 from 211, we get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 30

Let's proceed to step 6:
30 goes into 18 0 times with a remainder of 18.
The next digit of our result is 0. 
Result so far: 10570.0
If we take 0 away from 18, we end up with 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 30

Moving on to step 7:
When dividing 187 by 30, we get 6 with a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 105706.0
Subtracting 180 from 187 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 30

Step 8:
If we divide 72 by 30, we get 2 and a remainder of 12.
The next digit of our result is 2. 
Result so far: 1057062.0
If we take 60 away from 72, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
30 goes into 120 4 times with a remainder of 0.
The next digit of our result is 4. 
Result so far: 1057062.4
Deduct 120 from 120 and we're left 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.

Going ahead to step 10:
30 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1057062.4
If we subtract 0 from 0, 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 11:
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: 1057062.4
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.

After the division, we end up with 1057062.4 and a remainder of 0.0.
