453217 ÷ 30 
Our goal is to divide 453217 by 30.

Going ahead to step 1:
4 divided by 30 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 30

Step 2:
If we divide 45 by 30, we get 1 and a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 30 away from 45, we end up with 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 30

On to step 3:
30 can be fit into 153 5 times, resulting in a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 150 away from 153, we end up with 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 30

Let's proceed to step 4:
32 divided by 30 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 151.0
If we subtract 30 from 32, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 30

Going ahead to step 5:
When dividing 21 by 30, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 1510.0
Subtracting 0 from 21 leaves us with 21.
Include the next digit (7) from the dividend after 21, then repeat: 217 / 30

Step 6:
The number 30 fits into 217 7 times, leaving a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 15107.0
Subtract 210 from 217 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
30 can be fit into 70 2 times, resulting in a remainder of 10.
The next digit of our result is 2. 
Result so far: 15107.2
The remainder is 10 after subtracting 60 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
When dividing 100 by 30, we get 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 15107.23
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
When dividing 100 by 30, we get 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 15107.233
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 15107.233 and a remainder of 0.001.
