We're dividing 481521 by 51 
We want to divide 481521 by 51.

Moving on to step 1:
51 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 51

Let's proceed to step 2:
51 goes into 48 0 times with a remainder of 48.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Append the next digit (1) from the dividend to 48 and continue with: 481 / 51

Let's proceed to step 3:
481 divided by 51 is 9 with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 459 from 481, we get 22.
Take the next digit (5) from the dividend and append it to 22, then repeat: 225 / 51

Moving on to step 4:
The number 51 fits into 225 4 times, leaving a remainder of 21.
The next digit of our result is 4. 
Result so far: 94.0
If we take 204 away from 225, we end up with 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 51

Let's proceed to step 5:
When dividing 212 by 51, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 944.0
Subtracting 204 from 212 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 51

Let's proceed to step 6:
If we divide 81 by 51, we get 1 and a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 9441.0
Subtracting 51 from 81 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
When dividing 300 by 51, we get 5 with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 9441.5
Subtract 255 from 300 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 8:
450 divided by 51 is 8 with a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 9441.58
If we subtract 408 from 450, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 9:
51 can be fit into 420 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 9441.588
The remainder is 12 after subtracting 408 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 9441.588 with a remainder of 0.0012.
