453958 divided by 30 
We want to divide 453958 by 30.

Step 1:
If we divide 4 by 30, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 30

Let's proceed to step 2:
The number 30 fits into 45 1 times, leaving a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 15 after subtracting 30 from 45.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 30

Moving on to step 3:
The number 30 fits into 153 5 times, leaving a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 150 from 153 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 30

Step 4:
If we divide 39 by 30, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 151.0
Subtracting 30 from 39 leaves us with 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 30

On to step 5:
30 goes into 95 3 times with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 1513.0
If we take 90 away from 95, we end up with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 30

Step 6:
30 goes into 58 1 times with a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 15131.0
Subtracting 30 from 58 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 7:
The number 30 fits into 280 9 times, leaving a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 15131.9
Subtract 270 from 280 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 8:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 15131.93
If we take 90 away from 100, we end up 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.

Going ahead to step 9:
If we divide 100 by 30, we get 3 and a remainder of 10.
The next digit of our result is 3. 
Result so far: 15131.933
If we take 90 away from 100, we end up 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.

The final result is 15131.933 with a remainder of 0.001.
