430548 ÷ 42 
We're looking to find how many times 42 goes into 430548.

Going ahead to step 1:
4 divided by 42 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 42

On to step 2:
If we divide 43 by 42, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 42 from 43 to get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 42

Advancing to step 3:
42 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 10 after subtracting 0 from 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 42

Advancing to step 4:
When dividing 105 by 42, we get 2 with a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 102.0
If we subtract 84 from 105, we get 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 42

Step 5:
When dividing 214 by 42, we get 5 with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 1025.0
If we subtract 210 from 214, we get 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 42

Step 6:
42 goes into 48 1 times with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 10251.0
If we subtract 42 from 48, we 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.

Let's proceed to step 7:
42 can be fit into 60 1 times, resulting in a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 10251.1
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.

On 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: 10251.14
Subtracting 168 from 180 leaves us 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 9:
120 divided by 42 is 2 with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 10251.142
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.

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: 10251.1428
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.

On to step 11:
42 goes into 240 5 times with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 10251.14285
If we subtract 210 from 240, we 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.

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: 10251.142857
If we subtract 294 from 300, we 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.

Advancing to step 13:
42 can be fit into 60 1 times, resulting in a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 10251.1428571
If we take 42 away from 60, we end up 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.

Moving on to step 14:
180 divided by 42 is 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 10251.14285714
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.

The quotient of the division is 10251.14285714, and the remainder is 1.2e-08.
