We're dividing 53030537 by 30 
We want to divide 53030537 by 30.

Step 1:
The number 30 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 30

Step 2:
The number 30 fits into 53 1 times, leaving a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 30 from 53, we get 23.
Bring next digit (0) of the dividend behind the 23 and repeat the process: 230 / 30

On to step 3:
30 can be fit into 230 7 times, resulting in a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Deduct 210 from 230 and we're left with 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 30

Step 4:
203 divided by 30 is 6 with a remainder of 23.
Use 6 as the next digit of our solution. 
Result so far: 176.0
If we take 180 away from 203, we end up with 23.
Append the next digit (0) from the dividend to 23 and continue with: 230 / 30

Let's proceed to step 5:
The number 30 fits into 230 7 times, leaving a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 1767.0
If we subtract 210 from 230, we get 20.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 30

Step 6:
If we divide 205 by 30, we get 6 and a remainder of 25.
The number 6 becomes the next digit in our result. 
Result so far: 17676.0
Subtracting 180 from 205 leaves us with 25.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 30

Step 7:
30 goes into 253 8 times with a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 176768.0
Subtracting 240 from 253 leaves us with 13.
Append the next digit (7) from the dividend to 13 and continue with: 137 / 30

Step 8:
If we divide 137 by 30, we get 4 and a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 1767684.0
If we take 120 away from 137, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 9:
The number 30 fits into 170 5 times, leaving a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 1767684.5
If we take 150 away from 170, we end up 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.

Advancing to step 10:
30 goes into 200 6 times with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 1767684.56
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.

Step 11:
30 goes into 200 6 times with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 1767684.566
Deduct 180 from 200 and we're left 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.

The quotient of the division is 1767684.566, and the remainder is 0.002.
