Let's divide 396458 by 48
We're looking to find how many times 48 goes into 396458.

On to step 1:
If we divide 3 by 48, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 48

Going ahead to step 2:
The number 48 fits into 39 0 times, leaving a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Fetch the next digit (6) from the dividend, attach it to 39 and continue: 396 / 48

Let's proceed to step 3:
The number 48 fits into 396 8 times, leaving a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 384 away from 396, we end up with 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 48

On to step 4:
If we divide 124 by 48, we get 2 and a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 82.0
If we subtract 96 from 124, we get 28.
Bring next digit (5) of the dividend behind the 28 and repeat the process: 285 / 48

Moving on to step 5:
If we divide 285 by 48, we get 5 and a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 825.0
Deduct 240 from 285 and we're left with 45.
Take the next digit (8) from the dividend and append it to 45, then repeat: 458 / 48

Going ahead to step 6:
If we divide 458 by 48, we get 9 and a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 8259.0
Deduct 432 from 458 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 7:
The number 48 fits into 260 5 times, leaving a remainder of 20.
The next digit of our result is 5. 
Result so far: 8259.5
If we take 240 away from 260, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
48 goes into 200 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 8259.54
Deduct 192 from 200 and we're left 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.

Advancing to step 9:
The number 48 fits into 80 1 times, leaving a remainder of 32.
The next digit of our result is 1. 
Result so far: 8259.541
The remainder is 32 after subtracting 48 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
320 divided by 48 is 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 8259.5416
Subtracting 288 from 320 leaves us 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.

Going ahead to step 11:
When dividing 320 by 48, we get 6 with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 8259.54166
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.

Our division results in 8259.54166 with a remaining 3.2e-05.
