We look at the division of 671578 by 48 
We want to figure out the number of times 671578 can be divided by 48.

Moving on to step 1:
48 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 48

Step 2:
If we divide 67 by 48, we get 1 and a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 48 away from 67, we end up with 19.
Take the next digit (1) from the dividend and append it to 19, then repeat: 191 / 48

On to step 3:
191 divided by 48 is 3 with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 144 from 191, we get 47.
Grab the next digit (5) from the dividend, add it to 47, then carry on: 475 / 48

Let's proceed to step 4:
When dividing 475 by 48, we get 9 with a remainder of 43.
The next digit of our result is 9. 
Result so far: 139.0
Subtract 432 from 475 to get 43.
Fetch the next digit (7) from the dividend, attach it to 43 and continue: 437 / 48

Step 5:
When dividing 437 by 48, we get 9 with a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 1399.0
If we subtract 432 from 437, we get 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 48

Going ahead to step 6:
48 goes into 58 1 times with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 13991.0
If we subtract 48 from 58, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
When dividing 100 by 48, we get 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 13991.2
The remainder is 4 after subtracting 96 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
The number 48 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 13991.2
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
If we divide 400 by 48, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 13991.208
Subtract 384 from 400 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
160 divided by 48 is 3 with a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 13991.2083
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
The number 48 fits into 160 3 times, leaving a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 13991.20833
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 13991.20833 with a remainder of 1.6e-05.
