We're dividing 43146 by 30 
Our goal is to divide 43146 by 30.

On to step 1:
30 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 30

On to step 2:
The number 30 fits into 43 1 times, leaving a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 13 after subtracting 30 from 43.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 30

Going ahead to step 3:
30 goes into 131 4 times with a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we take 120 away from 131, we end up with 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 30

Going ahead to step 4:
When dividing 114 by 30, we get 3 with a remainder of 24.
The next digit of our result is 3. 
Result so far: 143.0
Subtracting 90 from 114 leaves us with 24.
Bring next digit (6) of the dividend behind the 24 and repeat the process: 246 / 30

Let's proceed to step 5:
30 can be fit into 246 8 times, resulting in a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 1438.0
Deduct 240 from 246 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 6:
30 can be fit into 60 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 1438.2
If we take 60 away from 60, 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.

On to step 7:
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: 1438.2
Subtract 0 from 0 to 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:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1438.2
The remainder is 0 after subtracting 0 from 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 quotient of the division is 1438.2, and the remainder is 0.0.
