We look at the division of 457379 by 30 
Our goal is to divide 457379 by 30.

Let's proceed to step 1:
30 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 30

Going ahead to step 2:
45 divided by 30 is 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 30 from 45 and we're left with 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 30

Advancing to step 3:
30 can be fit into 157 5 times, resulting in a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 150 from 157 leaves us with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 30

Advancing to step 4:
If we divide 73 by 30, we get 2 and a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 152.0
Deduct 60 from 73 and we're left with 13.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 30

Step 5:
If we divide 137 by 30, we get 4 and a remainder of 17.
Put 4 as the next digit of the answer. 
Result so far: 1524.0
If we take 120 away from 137, we end up with 17.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 30

Going ahead to step 6:
30 can be fit into 179 5 times, resulting in a remainder of 29.
Put 5 as the next digit of the answer. 
Result so far: 15245.0
Subtracting 150 from 179 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 7:
290 divided by 30 is 9 with a remainder of 20.
Put 9 as the next digit of the answer. 
Result so far: 15245.9
Subtracting 270 from 290 leaves us 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.

Step 8:
If we divide 200 by 30, we get 6 and a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 15245.96
Subtract 180 from 200 to 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.

Advancing to step 9:
When dividing 200 by 30, we get 6 with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 15245.966
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 15245.966 with a remainder of 0.002.
