We look at the division of 421393 by 22 
We want to figure out the number of times 421393 can be divided by 22.

Moving on to step 1:
The number 22 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 22

Let's proceed to step 2:
When dividing 42 by 22, we get 1 with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 22 from 42 and we're left with 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 22

Step 3:
If we divide 201 by 22, we get 9 and a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtract 198 from 201 to get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 22

Let's proceed to step 4:
If we divide 33 by 22, we get 1 and a remainder of 11.
The next digit of our result is 1. 
Result so far: 191.0
Deduct 22 from 33 and we're left with 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 22

Let's proceed to step 5:
22 can be fit into 119 5 times, resulting in a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 1915.0
The remainder is 9 after subtracting 110 from 119.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 22

Let's proceed to step 6:
The number 22 fits into 93 4 times, leaving a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 19154.0
The remainder is 5 after subtracting 88 from 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
50 divided by 22 is 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 19154.2
The remainder is 6 after subtracting 44 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
If we divide 60 by 22, we get 2 and a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 19154.22
Subtract 44 from 60 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 19154.22 with a balance of 0.016.
