We're dividing 543898 by 42 
Our goal is to divide 543898 by 42.

Moving on to step 1:
If we divide 5 by 42, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 42

Step 2:
54 divided by 42 is 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 42 from 54 leaves us with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 42

On to step 3:
The number 42 fits into 123 2 times, leaving a remainder of 39.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 39 after subtracting 84 from 123.
Append the next digit (8) from the dividend to 39 and continue with: 398 / 42

Let's proceed to step 4:
398 divided by 42 is 9 with a remainder of 20.
The next digit of our result is 9. 
Result so far: 129.0
Subtract 378 from 398 to get 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 42

Going ahead to step 5:
If we divide 209 by 42, we get 4 and a remainder of 41.
Use 4 as the next digit of our solution. 
Result so far: 1294.0
Subtracting 168 from 209 leaves us with 41.
Grab the next digit (8) from the dividend, add it to 41, then carry on: 418 / 42

On to step 6:
If we divide 418 by 42, we get 9 and a remainder of 40.
The number 9 becomes the next digit in our result. 
Result so far: 12949.0
Subtracting 378 from 418 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 7:
42 goes into 400 9 times with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 12949.9
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
If we divide 220 by 42, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 12949.95
Subtracting 210 from 220 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
42 can be fit into 100 2 times, resulting in a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 12949.952
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
The number 42 fits into 160 3 times, leaving a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 12949.9523
Subtract 126 from 160 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 11:
If we divide 340 by 42, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 12949.95238
If we take 336 away from 340, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
42 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 12949.95238
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
42 can be fit into 400 9 times, resulting in a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 12949.9523809
Subtract 378 from 400 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
42 goes into 220 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 12949.95238095
Deduct 210 from 220 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 12949.95238095, and the remainder is 1e-08.
