We're dividing 42278543 by 71 
We want to figure out the number of times 42278543 can be divided by 71.

Let's proceed to step 1:
71 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 71

Advancing to step 2:
42 divided by 71 is 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Take the next digit (2) from the dividend and append it to 42, then repeat: 422 / 71

Going ahead to step 3:
If we divide 422 by 71, we get 5 and a remainder of 67.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 355 from 422 leaves us with 67.
Fetch the next digit (7) from the dividend, attach it to 67 and continue: 677 / 71

Advancing to step 4:
71 can be fit into 677 9 times, resulting in a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 59.0
If we subtract 639 from 677, we get 38.
Fetch the next digit (8) from the dividend, attach it to 38 and continue: 388 / 71

Let's proceed to step 5:
The number 71 fits into 388 5 times, leaving a remainder of 33.
Record the quotient 5 as the next digit in the result. 
Result so far: 595.0
Subtract 355 from 388 to get 33.
Bring next digit (5) of the dividend behind the 33 and repeat the process: 335 / 71

Let's proceed to step 6:
The number 71 fits into 335 4 times, leaving a remainder of 51.
The number 4 becomes the next digit in our result. 
Result so far: 5954.0
The remainder is 51 after subtracting 284 from 335.
Append the next digit (4) from the dividend to 51 and continue with: 514 / 71

Let's proceed to step 7:
71 goes into 514 7 times with a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 59547.0
If we subtract 497 from 514, we get 17.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 71

Going ahead to step 8:
71 goes into 173 2 times with a remainder of 31.
The next digit of our result is 2. 
Result so far: 595472.0
Subtracting 142 from 173 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 9:
310 divided by 71 is 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 595472.4
If we subtract 284 from 310, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 10:
71 can be fit into 260 3 times, resulting in a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 595472.43
Subtract 213 from 260 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 11:
71 goes into 470 6 times with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 595472.436
Subtracting 426 from 470 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 12:
71 can be fit into 440 6 times, resulting in a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 595472.4366
If we subtract 426 from 440, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 595472.4366, with a leftover of 0.00014.
