We look at the division of 42595570 by 143 
We're looking to find how many times 143 goes into 42595570.

Step 1:
4 divided by 143 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
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 / 143

Step 2:
143 can be fit into 42 0 times, resulting in a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Fetch the next digit (5) from the dividend, attach it to 42 and continue: 425 / 143

Going ahead to step 3:
When dividing 425 by 143, we get 2 with a remainder of 139.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 139 after subtracting 286 from 425.
Grab the next digit (9) from the dividend, add it to 139, then carry on: 1399 / 143

Step 4:
143 goes into 1399 9 times with a remainder of 112.
Put 9 as the next digit of the answer. 
Result so far: 29.0
If we subtract 1287 from 1399, we get 112.
Bring next digit (5) of the dividend behind the 112 and repeat the process: 1125 / 143

Going ahead to step 5:
143 goes into 1125 7 times with a remainder of 124.
The number 7 becomes the next digit in our result. 
Result so far: 297.0
If we subtract 1001 from 1125, we get 124.
Append the next digit (5) from the dividend to 124 and continue with: 1245 / 143

Step 6:
143 goes into 1245 8 times with a remainder of 101.
The next digit of our result is 8. 
Result so far: 2978.0
Subtracting 1144 from 1245 leaves us with 101.
Append the next digit (7) from the dividend to 101 and continue with: 1017 / 143

Step 7:
The number 143 fits into 1017 7 times, leaving a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 29787.0
Deduct 1001 from 1017 and we're left with 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 143

Advancing to step 8:
If we divide 160 by 143, we get 1 and a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 297871.0
Deduct 143 from 160 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 9:
The number 143 fits into 170 1 times, leaving a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 297871.1
Subtracting 143 from 170 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 10:
143 goes into 270 1 times with a remainder of 127.
Write down 1 as next digit of the result. 
Result so far: 297871.11
Deduct 143 from 270 and we're left with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

After the division, we end up with 297871.11 and a remainder of 0.127.
