30168539 divided by 42 
We want to divide 30168539 by 42.

Advancing to step 1:
When dividing 3 by 42, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 42

Moving on to step 2:
42 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 42

On to step 3:
301 divided by 42 is 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 294 from 301, we get 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 42

Step 4:
76 divided by 42 is 1 with a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
Subtract 42 from 76 to get 34.
Take the next digit (8) from the dividend and append it to 34, then repeat: 348 / 42

Step 5:
42 goes into 348 8 times with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 718.0
The remainder is 12 after subtracting 336 from 348.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 42

Let's proceed to step 6:
42 can be fit into 125 2 times, resulting in a remainder of 41.
Write down 2 as next digit of the result. 
Result so far: 7182.0
Subtracting 84 from 125 leaves us with 41.
Include the next digit (3) from the dividend after 41, then repeat: 413 / 42

On to step 7:
The number 42 fits into 413 9 times, leaving a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 71829.0
Subtracting 378 from 413 leaves us with 35.
Take the next digit (9) from the dividend and append it to 35, then repeat: 359 / 42

On to step 8:
359 divided by 42 is 8 with a remainder of 23.
Record the quotient 8 as the next digit in the result. 
Result so far: 718298.0
If we subtract 336 from 359, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 9:
42 can be fit into 230 5 times, resulting in a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 718298.5
If we take 210 away from 230, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
42 goes into 200 4 times with a remainder of 32.
The next digit of our result is 4. 
Result so far: 718298.54
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 11:
The number 42 fits into 320 7 times, leaving a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 718298.547
If we subtract 294 from 320, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 12:
42 can be fit into 260 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 718298.5476
If we take 252 away from 260, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
When dividing 80 by 42, we get 1 with a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 718298.54761
Subtracting 42 from 80 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 14:
The number 42 fits into 380 9 times, leaving a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 718298.547619
If we subtract 378 from 380, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 15:
20 divided by 42 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 718298.547619
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 16:
42 goes into 200 4 times with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 718298.54761904
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 718298.54761904, and the remainder is 3.2e-08.
