We divide 451580 by 48
We want to divide 451580 by 48.

Going ahead to step 1:
If we divide 4 by 48, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 48

Advancing to step 2:
When dividing 45 by 48, we get 0 with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Include the next digit (1) from the dividend after 45, then repeat: 451 / 48

Let's proceed to step 3:
If we divide 451 by 48, we get 9 and a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 432 away from 451, we end up with 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 48

Step 4:
48 can be fit into 195 4 times, resulting in a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
The remainder is 3 after subtracting 192 from 195.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 48

Let's proceed to step 5:
The number 48 fits into 38 0 times, leaving a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 940.0
If we subtract 0 from 38, we get 38.
Bring next digit (0) of the dividend behind the 38 and repeat the process: 380 / 48

On to step 6:
If we divide 380 by 48, we get 7 and a remainder of 44.
Write down 7 as next digit of the result. 
Result so far: 9407.0
Subtract 336 from 380 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 7:
If we divide 440 by 48, we get 9 and a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 9407.9
If we take 432 away from 440, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
When dividing 80 by 48, we get 1 with a remainder of 32.
The next digit of our result is 1. 
Result so far: 9407.91
If we take 48 away from 80, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
320 divided by 48 is 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 9407.916
Subtract 288 from 320 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
The number 48 fits into 320 6 times, leaving a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 9407.9166
Deduct 288 from 320 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 9407.9166 with a remainder of 0.00032.
