We divide 429750 by 42
We want to figure out the number of times 429750 can be divided by 42.

Let's proceed to step 1:
If we divide 4 by 42, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 42

Going ahead to step 2:
42 can be fit into 42 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 42 from 42 and we're left with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 42

On to step 3:
42 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 9 to get 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 42

Going ahead to step 4:
If we divide 97 by 42, we get 2 and a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 102.0
Subtract 84 from 97 to get 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 42

Moving on to step 5:
If we divide 135 by 42, we get 3 and a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 1023.0
The remainder is 9 after subtracting 126 from 135.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 42

Let's proceed to step 6:
90 divided by 42 is 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 10232.0
If we take 84 away from 90, we end up 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.

Let's proceed to step 7:
42 can be fit into 60 1 times, resulting in a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 10232.1
Deduct 42 from 60 and we're left 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.

Going ahead to step 8:
When dividing 180 by 42, we get 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 10232.14
Deduct 168 from 180 and we're left 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.

Step 9:
120 divided by 42 is 2 with a remainder of 36.
The next digit of our result is 2. 
Result so far: 10232.142
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.

Advancing to step 10:
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: 10232.1428
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.

Moving on to step 11:
If we divide 240 by 42, we get 5 and a remainder of 30.
The next digit of our result is 5. 
Result so far: 10232.14285
Subtract 210 from 240 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
If we divide 300 by 42, we get 7 and a remainder of 6.
The next digit of our result is 7. 
Result so far: 10232.142857
If we take 294 away from 300, we end up 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 13:
When dividing 60 by 42, we get 1 with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 10232.1428571
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 14:
The number 42 fits into 180 4 times, leaving a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 10232.14285714
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 10232.14285714 with a remainder of 1.2e-08.
