We're dividing 42406259 by 22 
Our goal is to divide 42406259 by 22.

Advancing to step 1:
When dividing 4 by 22, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 22

Moving on to step 2:
22 goes into 42 1 times 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.
Fetch the next digit (4) from the dividend, attach it to 20 and continue: 204 / 22

On to step 3:
When dividing 204 by 22, we get 9 with a remainder of 6.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 198 from 204 and we're left with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 22

Going ahead to step 4:
If we divide 60 by 22, we get 2 and a remainder of 16.
The next digit of our result is 2. 
Result so far: 192.0
Deduct 44 from 60 and we're left with 16.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 22

Moving on to step 5:
When dividing 166 by 22, we get 7 with a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 1927.0
If we take 154 away from 166, we end up with 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 22

Moving on to step 6:
The number 22 fits into 122 5 times, leaving a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 19275.0
The remainder is 12 after subtracting 110 from 122.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 22

Step 7:
125 divided by 22 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 192755.0
Deduct 110 from 125 and we're left with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 22

Going ahead to step 8:
159 divided by 22 is 7 with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 1927557.0
Subtract 154 from 159 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
The number 22 fits into 50 2 times, leaving a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 1927557.2
Subtract 44 from 50 to get 6.
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 10:
If we divide 60 by 22, we get 2 and a remainder of 16.
The next digit of our result is 2. 
Result so far: 1927557.22
If we take 44 away from 60, we end up 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 1927557.22 with a remaining 0.016.
