We look at the division of 42039298 by 798 
Our goal is to divide 42039298 by 798.

Going ahead to step 1:
798 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
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 / 798

Going ahead to step 2:
The number 798 fits into 42 0 times, leaving a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Append the next digit (0) from the dividend to 42 and continue with: 420 / 798

Advancing to step 3:
798 goes into 420 0 times with a remainder of 420.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 420, we end up with 420.
Fetch the next digit (3) from the dividend, attach it to 420 and continue: 4203 / 798

On to step 4:
4203 divided by 798 is 5 with a remainder of 213.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 3990 from 4203 to get 213.
Include the next digit (9) from the dividend after 213, then repeat: 2139 / 798

Advancing to step 5:
798 can be fit into 2139 2 times, resulting in a remainder of 543.
Put 2 as the next digit of the answer. 
Result so far: 52.0
If we take 1596 away from 2139, we end up with 543.
Append the next digit (2) from the dividend to 543 and continue with: 5432 / 798

Let's proceed to step 6:
798 can be fit into 5432 6 times, resulting in a remainder of 644.
The number 6 becomes the next digit in our result. 
Result so far: 526.0
Deduct 4788 from 5432 and we're left with 644.
Take the next digit (9) from the dividend and append it to 644, then repeat: 6449 / 798

On to step 7:
6449 divided by 798 is 8 with a remainder of 65.
Record the quotient 8 as the next digit in the result. 
Result so far: 5268.0
Deduct 6384 from 6449 and we're left with 65.
Fetch the next digit (8) from the dividend, attach it to 65 and continue: 658 / 798

On to step 8:
658 divided by 798 is 0 with a remainder of 658.
The number 0 becomes the next digit in our result. 
Result so far: 52680.0
If we subtract 0 from 658, we get 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

Advancing to step 9:
If we divide 6580 by 798, we get 8 and a remainder of 196.
Put 8 as the next digit of the answer. 
Result so far: 52680.8
Subtract 6384 from 6580 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Advancing to step 10:
798 goes into 1960 2 times with a remainder of 364.
Use 2 as the next digit of our solution. 
Result so far: 52680.82
The remainder is 364 after subtracting 1596 from 1960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Step 11:
798 goes into 3640 4 times with a remainder of 448.
The number 4 becomes the next digit in our result. 
Result so far: 52680.824
If we take 3192 away from 3640, we end up with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

On to step 12:
When dividing 4480 by 798, we get 5 with a remainder of 490.
Put 5 as the next digit of the answer. 
Result so far: 52680.8245
If we subtract 3990 from 4480, we get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 13:
798 goes into 4900 6 times with a remainder of 112.
Use 6 as the next digit of our solution. 
Result so far: 52680.82456
If we subtract 4788 from 4900, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 14:
798 can be fit into 1120 1 times, resulting in a remainder of 322.
Use 1 as the next digit of our solution. 
Result so far: 52680.824561
Deduct 798 from 1120 and we're left with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Advancing to step 15:
The number 798 fits into 3220 4 times, leaving a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 52680.8245614
If we take 3192 away from 3220, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 16:
798 goes into 280 0 times with a remainder of 280.
The number 0 becomes the next digit in our result. 
Result so far: 52680.8245614
Subtracting 0 from 280 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

After the division, we end up with 52680.8245614 and a remainder of 2.8e-07.
