42079088 ÷ 77 
Our goal is to divide 42079088 by 77.

Moving on to step 1:
4 divided by 77 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 77

On to step 2:
77 can be fit into 42 0 times, resulting in a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 77

Let's proceed to step 3:
77 goes into 420 5 times with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 35 after subtracting 385 from 420.
Fetch the next digit (7) from the dividend, attach it to 35 and continue: 357 / 77

Going ahead to step 4:
77 can be fit into 357 4 times, resulting in a remainder of 49.
Use 4 as the next digit of our solution. 
Result so far: 54.0
Deduct 308 from 357 and we're left with 49.
Bring next digit (9) of the dividend behind the 49 and repeat the process: 499 / 77

On to step 5:
499 divided by 77 is 6 with a remainder of 37.
The number 6 becomes the next digit in our result. 
Result so far: 546.0
If we take 462 away from 499, we end up with 37.
Append the next digit (0) from the dividend to 37 and continue with: 370 / 77

Going ahead to step 6:
77 goes into 370 4 times with a remainder of 62.
The next digit of our result is 4. 
Result so far: 5464.0
The remainder is 62 after subtracting 308 from 370.
Take the next digit (8) from the dividend and append it to 62, then repeat: 628 / 77

Advancing to step 7:
77 goes into 628 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 54648.0
Subtract 616 from 628 to get 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 77

On to step 8:
If we divide 128 by 77, we get 1 and a remainder of 51.
The next digit of our result is 1. 
Result so far: 546481.0
If we take 77 away from 128, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 9:
If we divide 510 by 77, we get 6 and a remainder of 48.
The next digit of our result is 6. 
Result so far: 546481.6
If we take 462 away from 510, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
77 goes into 480 6 times with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 546481.66
Subtract 462 from 480 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 546481.66, with a leftover of 0.018.
