Let's divide 48255860 by 521
We want to figure out the number of times 48255860 can be divided by 521.

Step 1:
521 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 521

Step 2:
521 can be fit into 48 0 times, resulting in a remainder of 48.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 48 leaves us with 48.
Bring next digit (2) of the dividend behind the 48 and repeat the process: 482 / 521

Going ahead to step 3:
The number 521 fits into 482 0 times, leaving a remainder of 482.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 482, we get 482.
Include the next digit (5) from the dividend after 482, then repeat: 4825 / 521

Moving on to step 4:
4825 divided by 521 is 9 with a remainder of 136.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 136 after subtracting 4689 from 4825.
Grab the next digit (5) from the dividend, add it to 136, then carry on: 1365 / 521

Step 5:
When dividing 1365 by 521, we get 2 with a remainder of 323.
The number 2 becomes the next digit in our result. 
Result so far: 92.0
If we subtract 1042 from 1365, we get 323.
Append the next digit (8) from the dividend to 323 and continue with: 3238 / 521

Advancing to step 6:
3238 divided by 521 is 6 with a remainder of 112.
Use 6 as the next digit of our solution. 
Result so far: 926.0
If we subtract 3126 from 3238, we get 112.
Grab the next digit (6) from the dividend, add it to 112, then carry on: 1126 / 521

Moving on to step 7:
The number 521 fits into 1126 2 times, leaving a remainder of 84.
The number 2 becomes the next digit in our result. 
Result so far: 9262.0
Subtract 1042 from 1126 to get 84.
Fetch the next digit (0) from the dividend, attach it to 84 and continue: 840 / 521

Advancing to step 8:
If we divide 840 by 521, we get 1 and a remainder of 319.
Record the quotient 1 as the next digit in the result. 
Result so far: 92621.0
The remainder is 319 after subtracting 521 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Moving on to step 9:
When dividing 3190 by 521, we get 6 with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 92621.6
If we take 3126 away from 3190, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 10:
When dividing 640 by 521, we get 1 with a remainder of 119.
Record the quotient 1 as the next digit in the result. 
Result so far: 92621.61
The remainder is 119 after subtracting 521 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

On to step 11:
521 goes into 1190 2 times with a remainder of 148.
Use 2 as the next digit of our solution. 
Result so far: 92621.612
Subtract 1042 from 1190 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 12:
1480 divided by 521 is 2 with a remainder of 438.
Record the quotient 2 as the next digit in the result. 
Result so far: 92621.6122
The remainder is 438 after subtracting 1042 from 1480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

The final result is 92621.6122 with a remainder of 0.00438.
