621422 divided by 4 
We want to divide 621422 by 4.

On to step 1:
When dividing 6 by 4, we get 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 2 after subtracting 4 from 6.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 4

Let's proceed to step 2:
If we divide 22 by 4, we get 5 and a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 20 from 22 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 4

Going ahead to step 3:
21 divided by 4 is 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 155.0
Subtract 20 from 21 to get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 4

Let's proceed to step 4:
14 divided by 4 is 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 1553.0
If we take 12 away from 14, we end up with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 4

Going ahead to step 5:
4 can be fit into 22 5 times, resulting in a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 15535.0
Deduct 20 from 22 and we're left with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 4

Step 6:
If we divide 22 by 4, we get 5 and a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 155355.0
The remainder is 2 after subtracting 20 from 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
When dividing 20 by 4, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 155355.5
The remainder is 0 after subtracting 20 from 20.
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:
0 divided by 4 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 155355.5
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.

Step 9:
When dividing 0 by 4, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 155355.5
Subtracting 0 from 0 leaves us 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.

The final outcome is 155355.5, with a leftover of 0.0.
