543141 divided by 42 
Let's see how many times 42 fits into 543141.

Moving on to step 1:
42 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 42

Going ahead to step 2:
54 divided by 42 is 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 12 after subtracting 42 from 54.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 42

On to step 3:
42 goes into 123 2 times with a remainder of 39.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 84 from 123 to get 39.
Fetch the next digit (1) from the dividend, attach it to 39 and continue: 391 / 42

Advancing to step 4:
When dividing 391 by 42, we get 9 with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 129.0
Subtract 378 from 391 to get 13.
Grab the next digit (4) from the dividend, add it to 13, then carry on: 134 / 42

Going ahead to step 5:
If we divide 134 by 42, we get 3 and a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 1293.0
The remainder is 8 after subtracting 126 from 134.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 42

Going ahead to step 6:
42 goes into 81 1 times with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 12931.0
Subtracting 42 from 81 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 7:
If we divide 390 by 42, we get 9 and a remainder of 12.
The next digit of our result is 9. 
Result so far: 12931.9
Deduct 378 from 390 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
When dividing 120 by 42, we get 2 with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 12931.92
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 9:
360 divided by 42 is 8 with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 12931.928
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
If we divide 240 by 42, we get 5 and a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 12931.9285
Subtracting 210 from 240 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
42 goes into 300 7 times with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 12931.92857
The remainder is 6 after subtracting 294 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 12:
When dividing 60 by 42, we get 1 with a remainder of 18.
The next digit of our result is 1. 
Result so far: 12931.928571
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 13:
When dividing 180 by 42, we get 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 12931.9285714
Deduct 168 from 180 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
When dividing 120 by 42, we get 2 with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 12931.92857142
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 12931.92857142 and a remainder of 3.6e-08.
