We divide 42621871 by 799
We want to divide 42621871 by 799.

Moving on to step 1:
4 divided by 799 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 799

On to step 2:
799 goes into 42 0 times with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Bring next digit (6) of the dividend behind the 42 and repeat the process: 426 / 799

Advancing to step 3:
The number 799 fits into 426 0 times, leaving a remainder of 426.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 426 after subtracting 0 from 426.
Include the next digit (2) from the dividend after 426, then repeat: 4262 / 799

Going ahead to step 4:
799 can be fit into 4262 5 times, resulting in a remainder of 267.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 3995 from 4262 and we're left with 267.
Fetch the next digit (1) from the dividend, attach it to 267 and continue: 2671 / 799

Advancing to step 5:
2671 divided by 799 is 3 with a remainder of 274.
The next digit of our result is 3. 
Result so far: 53.0
Deduct 2397 from 2671 and we're left with 274.
Take the next digit (8) from the dividend and append it to 274, then repeat: 2748 / 799

Advancing to step 6:
When dividing 2748 by 799, we get 3 with a remainder of 351.
Use 3 as the next digit of our solution. 
Result so far: 533.0
Deduct 2397 from 2748 and we're left with 351.
Fetch the next digit (7) from the dividend, attach it to 351 and continue: 3517 / 799

Let's proceed to step 7:
799 can be fit into 3517 4 times, resulting in a remainder of 321.
Put 4 as the next digit of the answer. 
Result so far: 5334.0
Subtract 3196 from 3517 to get 321.
Bring next digit (1) of the dividend behind the 321 and repeat the process: 3211 / 799

Going ahead to step 8:
799 can be fit into 3211 4 times, resulting in a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 53344.0
Subtract 3196 from 3211 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
799 can be fit into 150 0 times, resulting in a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 53344.0
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 10:
799 can be fit into 1500 1 times, resulting in a remainder of 701.
Use 1 as the next digit of our solution. 
Result so far: 53344.01
Subtracting 799 from 1500 leaves us with 701.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7010, and continue the process.

Going ahead to step 11:
7010 divided by 799 is 8 with a remainder of 618.
The number 8 becomes the next digit in our result. 
Result so far: 53344.018
The remainder is 618 after subtracting 6392 from 7010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

On to step 12:
If we divide 6180 by 799, we get 7 and a remainder of 587.
Write down 7 as next digit of the result. 
Result so far: 53344.0187
Subtracting 5593 from 6180 leaves us with 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

Going ahead to step 13:
5870 divided by 799 is 7 with a remainder of 277.
Use 7 as the next digit of our solution. 
Result so far: 53344.01877
If we subtract 5593 from 5870, we get 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

After the division, we end up with 53344.01877 and a remainder of 0.000277.
