We're dividing 80359623 by 42 
Our goal is to divide 80359623 by 42.

Going ahead to step 1:
When dividing 8 by 42, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 42

Step 2:
The number 42 fits into 80 1 times, leaving a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 42 from 80 leaves us with 38.
Bring next digit (3) of the dividend behind the 38 and repeat the process: 383 / 42

Going ahead to step 3:
383 divided by 42 is 9 with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 5 after subtracting 378 from 383.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 42

Step 4:
The number 42 fits into 55 1 times, leaving a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 191.0
Deduct 42 from 55 and we're left with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 42

Let's proceed to step 5:
42 can be fit into 139 3 times, resulting in a remainder of 13.
The next digit of our result is 3. 
Result so far: 1913.0
Subtracting 126 from 139 leaves us with 13.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 42

Going ahead to step 6:
If we divide 136 by 42, we get 3 and a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 19133.0
If we subtract 126 from 136, we get 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 42

Going ahead to step 7:
42 goes into 102 2 times with a remainder of 18.
The next digit of our result is 2. 
Result so far: 191332.0
If we take 84 away from 102, we end up with 18.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 42

On to step 8:
If we divide 183 by 42, we get 4 and a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 1913324.0
Deduct 168 from 183 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
150 divided by 42 is 3 with a remainder of 24.
The next digit of our result is 3. 
Result so far: 1913324.3
Deduct 126 from 150 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.

Going ahead to step 10:
When dividing 240 by 42, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 1913324.35
The remainder is 30 after subtracting 210 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
42 can be fit into 300 7 times, resulting in a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 1913324.357
Subtract 294 from 300 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 12:
If we divide 60 by 42, we get 1 and a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1913324.3571
Subtract 42 from 60 to 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.

On to step 13:
42 can be fit into 180 4 times, resulting in a remainder of 12.
The next digit of our result is 4. 
Result so far: 1913324.35714
If we take 168 away from 180, we end up 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.

Let's proceed to step 14:
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: 1913324.357142
Subtracting 84 from 120 leaves us 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.

Step 15:
If we divide 360 by 42, we get 8 and a remainder of 24.
The next digit of our result is 8. 
Result so far: 1913324.3571428
The remainder is 24 after subtracting 336 from 360.
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 16:
The number 42 fits into 240 5 times, leaving a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 1913324.35714285
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.

In conclusion, the division gives 1913324.35714285 with a balance of 3e-08.
