42875958 divided by 142 
We want to divide 42875958 by 142.

Step 1:
When dividing 4 by 142, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 142

Moving on to step 2:
The number 142 fits into 42 0 times, leaving a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Grab the next digit (8) from the dividend, add it to 42, then carry on: 428 / 142

On to step 3:
If we divide 428 by 142, we get 3 and a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 426 from 428 leaves us with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 142

On to step 4:
142 goes into 27 0 times with a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
If we subtract 0 from 27, we get 27.
Grab the next digit (5) from the dividend, add it to 27, then carry on: 275 / 142

Let's proceed to step 5:
275 divided by 142 is 1 with a remainder of 133.
Put 1 as the next digit of the answer. 
Result so far: 301.0
If we take 142 away from 275, we end up with 133.
Take the next digit (9) from the dividend and append it to 133, then repeat: 1339 / 142

Moving on to step 6:
If we divide 1339 by 142, we get 9 and a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 3019.0
Subtracting 1278 from 1339 leaves us with 61.
Bring next digit (5) of the dividend behind the 61 and repeat the process: 615 / 142

Advancing to step 7:
142 goes into 615 4 times with a remainder of 47.
Use 4 as the next digit of our solution. 
Result so far: 30194.0
Deduct 568 from 615 and we're left with 47.
Grab the next digit (8) from the dividend, add it to 47, then carry on: 478 / 142

Going ahead to step 8:
If we divide 478 by 142, we get 3 and a remainder of 52.
The number 3 becomes the next digit in our result. 
Result so far: 301943.0
Subtracting 426 from 478 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 9:
142 goes into 520 3 times with a remainder of 94.
Record the quotient 3 as the next digit in the result. 
Result so far: 301943.3
If we take 426 away from 520, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 10:
940 divided by 142 is 6 with a remainder of 88.
Write down 6 as next digit of the result. 
Result so far: 301943.36
Deduct 852 from 940 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 11:
If we divide 880 by 142, we get 6 and a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 301943.366
If we subtract 852 from 880, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 301943.366 and a remainder of 0.0028.
