We're dividing 422643 by 42 
Our goal is to divide 422643 by 42.

Step 1:
4 divided by 42 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 42

Let's proceed to step 2:
When dividing 42 by 42, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 42 away from 42, we end up with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 42

Moving on to step 3:
The number 42 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 42

On to step 4:
When dividing 26 by 42, we get 0 with a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 100.0
The remainder is 26 after subtracting 0 from 26.
Append the next digit (4) from the dividend to 26 and continue with: 264 / 42

Step 5:
264 divided by 42 is 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 1006.0
If we take 252 away from 264, we end up with 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 42

Going ahead to step 6:
42 can be fit into 123 2 times, resulting in a remainder of 39.
Use 2 as the next digit of our solution. 
Result so far: 10062.0
The remainder is 39 after subtracting 84 from 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
When dividing 390 by 42, we get 9 with a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 10062.9
If we take 378 away from 390, 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.

On to step 8:
42 goes into 120 2 times with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 10062.92
The remainder is 36 after subtracting 84 from 120.
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 9:
If we divide 360 by 42, we get 8 and a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 10062.928
If we subtract 336 from 360, we get 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:
42 can be fit into 240 5 times, resulting in a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 10062.9285
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.

Going ahead to step 11:
If we divide 300 by 42, we get 7 and a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 10062.92857
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.

Step 12:
If we divide 60 by 42, we get 1 and a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 10062.928571
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.

Advancing to step 13:
42 goes into 180 4 times with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 10062.9285714
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.

Let's proceed to step 14:
120 divided by 42 is 2 with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 10062.92857142
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.

The quotient of the division is 10062.92857142, and the remainder is 3.6e-08.
