42810258 ÷ 979 
Our goal is to divide 42810258 by 979.

On to step 1:
4 divided by 979 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 979

Step 2:
The number 979 fits into 42 0 times, leaving a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Take the next digit (8) from the dividend and append it to 42, then repeat: 428 / 979

Going ahead to step 3:
428 divided by 979 is 0 with a remainder of 428.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 428 and we're left with 428.
Fetch the next digit (1) from the dividend, attach it to 428 and continue: 4281 / 979

On to step 4:
When dividing 4281 by 979, we get 4 with a remainder of 365.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 3916 from 4281 leaves us with 365.
Take the next digit (0) from the dividend and append it to 365, then repeat: 3650 / 979

Let's proceed to step 5:
3650 divided by 979 is 3 with a remainder of 713.
The next digit of our result is 3. 
Result so far: 43.0
The remainder is 713 after subtracting 2937 from 3650.
Take the next digit (2) from the dividend and append it to 713, then repeat: 7132 / 979

Step 6:
The number 979 fits into 7132 7 times, leaving a remainder of 279.
Put 7 as the next digit of the answer. 
Result so far: 437.0
Deduct 6853 from 7132 and we're left with 279.
Bring next digit (5) of the dividend behind the 279 and repeat the process: 2795 / 979

Step 7:
The number 979 fits into 2795 2 times, leaving a remainder of 837.
Put 2 as the next digit of the answer. 
Result so far: 4372.0
Subtracting 1958 from 2795 leaves us with 837.
Take the next digit (8) from the dividend and append it to 837, then repeat: 8378 / 979

On to step 8:
979 can be fit into 8378 8 times, resulting in a remainder of 546.
Use 8 as the next digit of our solution. 
Result so far: 43728.0
Subtract 7832 from 8378 to get 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Advancing to step 9:
The number 979 fits into 5460 5 times, leaving a remainder of 565.
The number 5 becomes the next digit in our result. 
Result so far: 43728.5
Deduct 4895 from 5460 and we're left with 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Going ahead to step 10:
979 goes into 5650 5 times with a remainder of 755.
Use 5 as the next digit of our solution. 
Result so far: 43728.55
If we subtract 4895 from 5650, we get 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

Our division results in 43728.55 with a remaining 0.755.
