We divide 521890 by 48
Our goal is to divide 521890 by 48.

Moving on to step 1:
48 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 48

Step 2:
If we divide 52 by 48, we get 1 and a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 48 from 52, we get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 48

Moving on to step 3:
When dividing 41 by 48, we get 0 with a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 41 leaves us with 41.
Take the next digit (8) from the dividend and append it to 41, then repeat: 418 / 48

On to step 4:
If we divide 418 by 48, we get 8 and a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 108.0
Subtract 384 from 418 to get 34.
Include the next digit (9) from the dividend after 34, then repeat: 349 / 48

Advancing to step 5:
If we divide 349 by 48, we get 7 and a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 1087.0
Subtracting 336 from 349 leaves us with 13.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 48

Let's proceed to step 6:
If we divide 130 by 48, we get 2 and a remainder of 34.
The next digit of our result is 2. 
Result so far: 10872.0
If we take 96 away from 130, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
48 goes into 340 7 times with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 10872.7
The remainder is 4 after subtracting 336 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
48 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 10872.7
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
48 goes into 400 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 10872.708
If we subtract 384 from 400, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
The number 48 fits into 160 3 times, leaving a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 10872.7083
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
When dividing 160 by 48, we get 3 with a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 10872.70833
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 10872.70833 and a remainder of 1.6e-05.
