We look at the division of 402426 by 4 
We want to figure out the number of times 402426 can be divided by 4.

Step 1:
The number 4 fits into 4 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 4 from 4 and we're left with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 4

Moving on to step 2:
0 divided by 4 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 0, we end up with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 4

Going ahead to step 3:
4 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 4

On to step 4:
When dividing 24 by 4, we get 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 1006.0
Subtracting 24 from 24 leaves us with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 4

Step 5:
If we divide 2 by 4, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 10060.0
If we subtract 0 from 2, we get 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 4

Advancing to step 6:
4 goes into 26 6 times with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 100606.0
If we subtract 24 from 26, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
When dividing 20 by 4, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 100606.5
If we take 20 away from 20, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 100606.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
0 divided by 4 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 100606.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 100606.5, with a leftover of 0.0.
