437103 ÷ 30 
Let's see how many times 30 fits into 437103.

Advancing to step 1:
30 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (3) from the dividend after 4, then repeat: 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.
Append the next digit (7) from the dividend to 13 and continue with: 137 / 30

Step 3:
30 goes into 137 4 times with a remainder of 17.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 17 after subtracting 120 from 137.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 30

Moving on 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: 145.0
The remainder is 21 after subtracting 150 from 171.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 30

Advancing to step 5:
When dividing 210 by 30, we get 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 1457.0
Deduct 210 from 210 and we're left with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 30

On to step 6:
When dividing 3 by 30, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 14570.0
If we take 0 away from 3, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
30 goes into 30 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 14570.1
Deduct 30 from 30 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.

Step 8:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 14570.1
Deduct 0 from 0 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.

Step 9:
The number 30 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 14570.1
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.

The quotient of the division is 14570.1, and the remainder is 0.0.
