We divide 448386 by 51
We want to divide 448386 by 51.

Step 1:
51 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 51

Advancing to step 2:
51 can be fit into 44 0 times, resulting in a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 44, we get 44.
Grab the next digit (8) from the dividend, add it to 44, then carry on: 448 / 51

On to step 3:
51 can be fit into 448 8 times, resulting in a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 408 from 448 to get 40.
Grab the next digit (3) from the dividend, add it to 40, then carry on: 403 / 51

Step 4:
51 goes into 403 7 times with a remainder of 46.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
Subtracting 357 from 403 leaves us with 46.
Fetch the next digit (8) from the dividend, attach it to 46 and continue: 468 / 51

Moving on to step 5:
When dividing 468 by 51, we get 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 879.0
The remainder is 9 after subtracting 459 from 468.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 51

Moving on to step 6:
If we divide 96 by 51, we get 1 and a remainder of 45.
The next digit of our result is 1. 
Result so far: 8791.0
If we subtract 51 from 96, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 7:
The number 51 fits into 450 8 times, leaving a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 8791.8
Deduct 408 from 450 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 8:
51 goes into 420 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 8791.88
If we subtract 408 from 420, we 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.

After the division, we end up with 8791.88 and a remainder of 0.012.
