We're dividing 485448 by 42 
We're looking to find how many times 42 goes into 485448.

Let's proceed to step 1:
42 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 42

Going ahead to step 2:
42 goes into 48 1 times with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 42 from 48 and we're left with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 42

Going ahead to step 3:
The number 42 fits into 65 1 times, leaving a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 23 after subtracting 42 from 65.
Take the next digit (4) from the dividend and append it to 23, then repeat: 234 / 42

On to step 4:
234 divided by 42 is 5 with a remainder of 24.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
The remainder is 24 after subtracting 210 from 234.
Grab the next digit (4) from the dividend, add it to 24, then carry on: 244 / 42

On to step 5:
If we divide 244 by 42, we get 5 and a remainder of 34.
The next digit of our result is 5. 
Result so far: 1155.0
If we take 210 away from 244, we end up with 34.
Append the next digit (8) from the dividend to 34 and continue with: 348 / 42

Let's proceed to step 6:
When dividing 348 by 42, we get 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 11558.0
Subtract 336 from 348 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
If we divide 120 by 42, we get 2 and a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 11558.2
Subtract 84 from 120 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 8:
360 divided by 42 is 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 11558.28
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
240 divided by 42 is 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 11558.285
Subtracting 210 from 240 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.

Step 10:
The number 42 fits into 300 7 times, leaving a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 11558.2857
Subtract 294 from 300 to 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.

Advancing to step 11:
42 goes into 60 1 times with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 11558.28571
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 12:
180 divided by 42 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 11558.285714
If we take 168 away from 180, we end up 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.

Going ahead to step 13:
The number 42 fits into 120 2 times, leaving a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 11558.2857142
If we subtract 84 from 120, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 14:
360 divided by 42 is 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 11558.28571428
Subtract 336 from 360 to 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.

In conclusion, the division gives 11558.28571428 with a balance of 2.4e-08.
