We look at the division of 432729 by 42 
We want to divide 432729 by 42.

Advancing to step 1:
When dividing 4 by 42, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 42

Going ahead to step 2:
The number 42 fits into 43 1 times, leaving a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 42 away from 43, we end up with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 42

Advancing to step 3:
If we divide 12 by 42, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 12 after subtracting 0 from 12.
Append the next digit (7) from the dividend to 12 and continue with: 127 / 42

Let's proceed to step 4:
When dividing 127 by 42, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
Subtract 126 from 127 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 42

Going ahead to step 5:
When dividing 12 by 42, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 1030.0
If we take 0 away from 12, we end up with 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 42

Advancing to step 6:
129 divided by 42 is 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 10303.0
Subtracting 126 from 129 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
When dividing 30 by 42, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 10303.0
Subtract 0 from 30 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.

Advancing to step 8:
42 goes into 300 7 times with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 10303.07
Subtracting 294 from 300 leaves us 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.

Going ahead to step 9:
The number 42 fits into 60 1 times, leaving a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 10303.071
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.

Going ahead to step 10:
If we divide 180 by 42, we get 4 and a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 10303.0714
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.

On to step 11:
42 goes into 120 2 times with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 10303.07142
If we take 84 away from 120, we end up 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.

Moving on to step 12:
42 can be fit into 360 8 times, resulting in a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 10303.071428
If we take 336 away from 360, we end up 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 13:
42 can be fit into 240 5 times, resulting in a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 10303.0714285
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.

Going ahead to step 14:
42 goes into 300 7 times with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 10303.07142857
Subtracting 294 from 300 leaves us 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.

The quotient of the division is 10303.07142857, and the remainder is 6e-09.
