We look at the division of 942543 by 4 
We want to figure out the number of times 942543 can be divided by 4.

Step 1:
4 goes into 9 2 times with a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 1 after subtracting 8 from 9.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 4

Moving on to step 2:
If we divide 14 by 4, we get 3 and a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Subtract 12 from 14 to get 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 4

Going ahead to step 3:
22 divided by 4 is 5 with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 235.0
Subtract 20 from 22 to get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 4

Advancing to step 4:
If we divide 25 by 4, we get 6 and a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 2356.0
If we subtract 24 from 25, we get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 4

Let's proceed to step 5:
If we divide 14 by 4, we get 3 and a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 23563.0
If we take 12 away from 14, we end up with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 4

Advancing to step 6:
4 goes into 23 5 times with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 235635.0
Deduct 20 from 23 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
30 divided by 4 is 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 235635.7
Deduct 28 from 30 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
If we divide 20 by 4, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 235635.75
Subtracting 20 from 20 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
If we divide 0 by 4, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 235635.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 235635.75
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 235635.75 with a remainder of 0.0.
