Let's divide 420064 by 42
Let's see how many times 42 fits into 420064.

Step 1:
When dividing 4 by 42, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 42

Advancing to step 2:
42 goes into 42 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 42 from 42 and we're left with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 42

On to step 3:
When dividing 0 by 42, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 0, we get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 42

Step 4:
0 divided by 42 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
Subtract 0 from 0 to get 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 42

Step 5:
42 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 1000.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 42

Let's proceed to step 6:
42 can be fit into 64 1 times, resulting in a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 10001.0
If we subtract 42 from 64, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
When dividing 220 by 42, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 10001.5
Subtracting 210 from 220 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
42 can be fit into 100 2 times, resulting in a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 10001.52
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
When dividing 160 by 42, we get 3 with a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 10001.523
Subtract 126 from 160 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
When dividing 340 by 42, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 10001.5238
The remainder is 4 after subtracting 336 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
The number 42 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 10001.5238
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
If we divide 400 by 42, we get 9 and a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 10001.523809
Subtract 378 from 400 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 13:
When dividing 220 by 42, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 10001.5238095
If we take 210 away from 220, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 14:
If we divide 100 by 42, we get 2 and a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 10001.52380952
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 10001.52380952 with a remaining 1.6e-08.
