48310993 ÷ 30 
We want to divide 48310993 by 30.

Advancing to step 1:
When dividing 4 by 30, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 30

On to step 2:
48 divided by 30 is 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 30 from 48, we get 18.
Take the next digit (3) from the dividend and append it to 18, then repeat: 183 / 30

On to step 3:
The number 30 fits into 183 6 times, leaving a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 180 from 183 leaves us with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 30

Advancing to step 4:
When dividing 31 by 30, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 161.0
The remainder is 1 after subtracting 30 from 31.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 30

Let's proceed to step 5:
30 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 1610.0
If we take 0 away from 10, we end up with 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 30

Going ahead to step 6:
30 goes into 109 3 times with a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 16103.0
If we subtract 90 from 109, we get 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 30

On to step 7:
The number 30 fits into 199 6 times, leaving a remainder of 19.
Write down 6 as next digit of the result. 
Result so far: 161036.0
Subtracting 180 from 199 leaves us with 19.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 30

Let's proceed to step 8:
If we divide 193 by 30, we get 6 and a remainder of 13.
Put 6 as the next digit of the answer. 
Result so far: 1610366.0
Deduct 180 from 193 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 9:
30 can be fit into 130 4 times, resulting in a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 1610366.4
If we subtract 120 from 130, we 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.

Moving on to step 10:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 1610366.43
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.

Moving on to step 11:
30 goes into 100 3 times with a remainder of 10.
The next digit of our result is 3. 
Result so far: 1610366.433
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.

The quotient of the division is 1610366.433, and the remainder is 0.001.
