We're dividing 42420487 by 799 
Our goal is to divide 42420487 by 799.

Moving on to step 1:
799 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 take 0 away from 4, we end up with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 799

Step 2:
If we divide 42 by 799, we get 0 and a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Fetch the next digit (4) from the dividend, attach it to 42 and continue: 424 / 799

Going ahead to step 3:
The number 799 fits into 424 0 times, leaving a remainder of 424.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 424 and we're left with 424.
Grab the next digit (2) from the dividend, add it to 424, then carry on: 4242 / 799

Going ahead to step 4:
If we divide 4242 by 799, we get 5 and a remainder of 247.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 247 after subtracting 3995 from 4242.
Include the next digit (0) from the dividend after 247, then repeat: 2470 / 799

Moving on to step 5:
The number 799 fits into 2470 3 times, leaving a remainder of 73.
The next digit of our result is 3. 
Result so far: 53.0
The remainder is 73 after subtracting 2397 from 2470.
Grab the next digit (4) from the dividend, add it to 73, then carry on: 734 / 799

On to step 6:
799 goes into 734 0 times with a remainder of 734.
The next digit of our result is 0. 
Result so far: 530.0
Subtract 0 from 734 to get 734.
Include the next digit (8) from the dividend after 734, then repeat: 7348 / 799

Let's proceed to step 7:
799 goes into 7348 9 times with a remainder of 157.
Write down 9 as next digit of the result. 
Result so far: 5309.0
Deduct 7191 from 7348 and we're left with 157.
Take the next digit (7) from the dividend and append it to 157, then repeat: 1577 / 799

Moving on to step 8:
When dividing 1577 by 799, we get 1 with a remainder of 778.
The number 1 becomes the next digit in our result. 
Result so far: 53091.0
Subtracting 799 from 1577 leaves us with 778.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7780, and continue the process.

Step 9:
7780 divided by 799 is 9 with a remainder of 589.
Write down 9 as next digit of the result. 
Result so far: 53091.9
Subtracting 7191 from 7780 leaves us with 589.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5890, and continue the process.

Step 10:
799 goes into 5890 7 times with a remainder of 297.
Put 7 as the next digit of the answer. 
Result so far: 53091.97
The remainder is 297 after subtracting 5593 from 5890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Advancing to step 11:
799 goes into 2970 3 times with a remainder of 573.
Use 3 as the next digit of our solution. 
Result so far: 53091.973
Deduct 2397 from 2970 and we're left with 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Step 12:
799 goes into 5730 7 times with a remainder of 137.
The next digit of our result is 7. 
Result so far: 53091.9737
If we take 5593 away from 5730, we end up with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

On to step 13:
The number 799 fits into 1370 1 times, leaving a remainder of 571.
Write down 1 as next digit of the result. 
Result so far: 53091.97371
Subtract 799 from 1370 to get 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Going ahead to step 14:
If we divide 5710 by 799, we get 7 and a remainder of 117.
Write down 7 as next digit of the result. 
Result so far: 53091.973717
Subtract 5593 from 5710 to get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Moving on to step 15:
The number 799 fits into 1170 1 times, leaving a remainder of 371.
The next digit of our result is 1. 
Result so far: 53091.9737171
The remainder is 371 after subtracting 799 from 1170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

On to step 16:
3710 divided by 799 is 4 with a remainder of 514.
The number 4 becomes the next digit in our result. 
Result so far: 53091.97371714
The remainder is 514 after subtracting 3196 from 3710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Our division results in 53091.97371714 with a remaining 5.14e-07.
