We divide 253445 by 30
We're looking to find how many times 30 goes into 253445.

Step 1:
2 divided by 30 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 30

On to step 2:
The number 30 fits into 25 0 times, leaving a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Append the next digit (3) from the dividend to 25 and continue with: 253 / 30

Step 3:
30 can be fit into 253 8 times, resulting in a remainder of 13.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 13 after subtracting 240 from 253.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 30

Going ahead to step 4:
If we divide 134 by 30, we get 4 and a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
If we subtract 120 from 134, we get 14.
Bring next digit (4) of the dividend behind the 14 and repeat the process: 144 / 30

Going ahead to step 5:
30 goes into 144 4 times with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 844.0
If we subtract 120 from 144, we get 24.
Fetch the next digit (5) from the dividend, attach it to 24 and continue: 245 / 30

Step 6:
When dividing 245 by 30, we get 8 with a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 8448.0
If we subtract 240 from 245, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
The number 30 fits into 50 1 times, leaving a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 8448.1
Subtracting 30 from 50 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:
30 goes into 200 6 times with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 8448.16
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.

Going ahead to step 9:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 8448.166
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 quotient of the division is 8448.166, and the remainder is 0.002.
