68043831 divided by 42 
We want to figure out the number of times 68043831 can be divided by 42.

Advancing to step 1:
When dividing 6 by 42, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 42

Let's proceed to step 2:
42 goes into 68 1 times with a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 42 from 68 to get 26.
Fetch the next digit (0) from the dividend, attach it to 26 and continue: 260 / 42

Step 3:
260 divided by 42 is 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 252 from 260 and we're left with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 42

Moving on to step 4:
42 goes into 84 2 times with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 162.0
The remainder is 0 after subtracting 84 from 84.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 42

Let's proceed to step 5:
The number 42 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 1620.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 42

On to step 6:
42 goes into 38 0 times with a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 16200.0
The remainder is 38 after subtracting 0 from 38.
Append the next digit (3) from the dividend to 38 and continue with: 383 / 42

Let's proceed to step 7:
42 can be fit into 383 9 times, resulting in a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 162009.0
Deduct 378 from 383 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 42

Let's proceed to step 8:
51 divided by 42 is 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1620091.0
If we take 42 away from 51, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
If we divide 90 by 42, we get 2 and a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 1620091.2
Deduct 84 from 90 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 10:
The number 42 fits into 60 1 times, leaving a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1620091.21
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 11:
42 goes into 180 4 times with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 1620091.214
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
42 can be fit into 120 2 times, resulting in a remainder of 36.
The next digit of our result is 2. 
Result so far: 1620091.2142
If we subtract 84 from 120, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 13:
If we divide 360 by 42, we get 8 and a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 1620091.21428
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.

Let's proceed to step 14:
If we divide 240 by 42, we get 5 and a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 1620091.214285
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.

Let's proceed to step 15:
The number 42 fits into 300 7 times, leaving a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 1620091.2142857
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.

Step 16:
42 can be fit into 60 1 times, resulting in a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 1620091.21428571
Subtracting 42 from 60 leaves us 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.

After the division, we end up with 1620091.21428571 and a remainder of 1.8e-08.
