48624120 ÷ 521 
Our goal is to divide 48624120 by 521.

On to step 1:
521 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 521

On to step 2:
521 goes into 48 0 times with a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 48 leaves us with 48.
Bring next digit (6) of the dividend behind the 48 and repeat the process: 486 / 521

Going ahead to step 3:
521 goes into 486 0 times with a remainder of 486.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 486, we get 486.
Take the next digit (2) from the dividend and append it to 486, then repeat: 4862 / 521

Moving on to step 4:
521 can be fit into 4862 9 times, resulting in a remainder of 173.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 4689 away from 4862, we end up with 173.
Include the next digit (4) from the dividend after 173, then repeat: 1734 / 521

Going ahead to step 5:
If we divide 1734 by 521, we get 3 and a remainder of 171.
Write down 3 as next digit of the result. 
Result so far: 93.0
The remainder is 171 after subtracting 1563 from 1734.
Grab the next digit (1) from the dividend, add it to 171, then carry on: 1711 / 521

Moving on to step 6:
521 can be fit into 1711 3 times, resulting in a remainder of 148.
The next digit of our result is 3. 
Result so far: 933.0
Deduct 1563 from 1711 and we're left with 148.
Append the next digit (2) from the dividend to 148 and continue with: 1482 / 521

Going ahead to step 7:
The number 521 fits into 1482 2 times, leaving a remainder of 440.
The next digit of our result is 2. 
Result so far: 9332.0
The remainder is 440 after subtracting 1042 from 1482.
Grab the next digit (0) from the dividend, add it to 440, then carry on: 4400 / 521

Going ahead to step 8:
4400 divided by 521 is 8 with a remainder of 232.
The next digit of our result is 8. 
Result so far: 93328.0
If we subtract 4168 from 4400, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

On to step 9:
The number 521 fits into 2320 4 times, leaving a remainder of 236.
The number 4 becomes the next digit in our result. 
Result so far: 93328.4
Deduct 2084 from 2320 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Let's proceed to step 10:
521 goes into 2360 4 times with a remainder of 276.
Use 4 as the next digit of our solution. 
Result so far: 93328.44
If we subtract 2084 from 2360, we get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

The quotient of the division is 93328.44, and the remainder is 0.276.
