307112 divided by 30 
We want to divide 307112 by 30.

Advancing to step 1:
The number 30 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 30

Going ahead to step 2:
The number 30 fits into 30 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 30 from 30, we get 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 30

Going ahead to step 3:
30 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 30

On to step 4:
71 divided by 30 is 2 with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
Subtracting 60 from 71 leaves us with 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 30

Going ahead to step 5:
When dividing 111 by 30, we get 3 with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 1023.0
Subtracting 90 from 111 leaves us with 21.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 30

On to step 6:
The number 30 fits into 212 7 times, leaving a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 10237.0
Subtract 210 from 212 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
30 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 10237.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
The number 30 fits into 200 6 times, leaving a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 10237.06
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
The number 30 fits into 200 6 times, leaving a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 10237.066
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 10237.066 with a remaining 0.002.
