We look at the division of 990001 by 42 
Let's see how many times 42 fits into 990001.

Moving on to step 1:
If we divide 9 by 42, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 42

On to step 2:
42 goes into 99 2 times with a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 84 from 99 to get 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 42

Going ahead to step 3:
150 divided by 42 is 3 with a remainder of 24.
The next digit of our result is 3. 
Result so far: 23.0
If we subtract 126 from 150, we get 24.
Bring next digit (0) of the dividend behind the 24 and repeat the process: 240 / 42

On to step 4:
The number 42 fits into 240 5 times, leaving a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 235.0
If we subtract 210 from 240, we get 30.
Include the next digit (0) from the dividend after 30, then repeat: 300 / 42

Going ahead to step 5:
If we divide 300 by 42, we get 7 and a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 2357.0
Deduct 294 from 300 and we're left with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 42

Let's proceed to step 6:
The number 42 fits into 61 1 times, leaving a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 23571.0
If we subtract 42 from 61, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
42 can be fit into 190 4 times, resulting in a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 23571.4
Subtract 168 from 190 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.

Moving on to step 8:
42 can be fit into 220 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 23571.45
If we subtract 210 from 220, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
When dividing 100 by 42, we get 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 23571.452
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
When dividing 160 by 42, we get 3 with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 23571.4523
If we take 126 away from 160, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 11:
42 can be fit into 340 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 23571.45238
If we subtract 336 from 340, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
When dividing 40 by 42, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 23571.45238
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
400 divided by 42 is 9 with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 23571.4523809
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 14:
If we divide 220 by 42, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 23571.45238095
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.

The final outcome is 23571.45238095, with a leftover of 1e-08.
