We look at the division of 355590 by 48 
We're looking to find how many times 48 goes into 355590.

Moving on to step 1:
If we divide 3 by 48, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 48

Step 2:
If we divide 35 by 48, we get 0 and a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Bring next digit (5) of the dividend behind the 35 and repeat the process: 355 / 48

Going ahead to step 3:
If we divide 355 by 48, we get 7 and a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 336 from 355 leaves us with 19.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 48

Going ahead to step 4:
48 can be fit into 195 4 times, resulting in a remainder of 3.
The next digit of our result is 4. 
Result so far: 74.0
Subtracting 192 from 195 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 48

Going ahead to step 5:
When dividing 39 by 48, we get 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 740.0
Subtract 0 from 39 to get 39.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 48

Going ahead to step 6:
When dividing 390 by 48, we get 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 7408.0
If we subtract 384 from 390, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
60 divided by 48 is 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 7408.1
Deduct 48 from 60 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
When dividing 120 by 48, we get 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 7408.12
If we subtract 96 from 120, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
When dividing 240 by 48, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 7408.125
The remainder is 0 after subtracting 240 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
0 divided by 48 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7408.125
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
If we divide 0 by 48, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7408.125
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 7408.125 with a remaining 0.0.
