30021087 ÷ 48 
Our goal is to divide 30021087 by 48.

On to step 1:
48 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 48

On to step 2:
48 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Take the next digit (0) from the dividend and append it to 30, then repeat: 300 / 48

Step 3:
300 divided by 48 is 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtracting 288 from 300 leaves us with 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 48

Step 4:
48 goes into 122 2 times with a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 62.0
The remainder is 26 after subtracting 96 from 122.
Grab the next digit (1) from the dividend, add it to 26, then carry on: 261 / 48

Advancing to step 5:
261 divided by 48 is 5 with a remainder of 21.
Put 5 as the next digit of the answer. 
Result so far: 625.0
If we subtract 240 from 261, we get 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 48

Let's proceed to step 6:
When dividing 210 by 48, we get 4 with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 6254.0
Subtract 192 from 210 to get 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 48

On to step 7:
When dividing 188 by 48, we get 3 with a remainder of 44.
Write down 3 as next digit of the result. 
Result so far: 62543.0
Subtracting 144 from 188 leaves us with 44.
Append the next digit (7) from the dividend to 44 and continue with: 447 / 48

Let's proceed to step 8:
48 can be fit into 447 9 times, resulting in a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 625439.0
If we take 432 away from 447, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
When dividing 150 by 48, we get 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 625439.3
Subtract 144 from 150 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
The number 48 fits into 60 1 times, leaving a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 625439.31
If we subtract 48 from 60, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
If we divide 120 by 48, we get 2 and a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 625439.312
If we subtract 96 from 120, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
When dividing 240 by 48, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 625439.3125
If we take 240 away from 240, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 13:
The number 48 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 625439.3125
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 14:
If we divide 0 by 48, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 625439.3125
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 625439.3125 with a balance of 0.0.
