580388 ÷ 22 
Let's see how many times 22 fits into 580388.

Advancing to step 1:
If we divide 5 by 22, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 22

Moving on to step 2:
If we divide 58 by 22, we get 2 and a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 44 from 58 and we're left with 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 22

Let's proceed to step 3:
22 can be fit into 140 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
The remainder is 8 after subtracting 132 from 140.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 22

Let's proceed to step 4:
22 goes into 83 3 times with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 263.0
Subtracting 66 from 83 leaves us with 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 22

Going ahead to step 5:
If we divide 178 by 22, we get 8 and a remainder of 2.
The next digit of our result is 8. 
Result so far: 2638.0
Deduct 176 from 178 and we're left with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 22

Going ahead to step 6:
When dividing 28 by 22, we get 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 26381.0
If we take 22 away from 28, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
The number 22 fits into 60 2 times, leaving a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 26381.2
Subtracting 44 from 60 leaves us 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.

On to step 8:
If we divide 160 by 22, we get 7 and a remainder of 6.
The next digit of our result is 7. 
Result so far: 26381.27
If we take 154 away from 160, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
60 divided by 22 is 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 26381.272
Deduct 44 from 60 and we're left 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.

Let's proceed to step 10:
22 goes into 160 7 times with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 26381.2727
If we take 154 away from 160, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
The number 22 fits into 60 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 26381.27272
Deduct 44 from 60 and we're left 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.

Going ahead to step 12:
If we divide 160 by 22, we get 7 and a remainder of 6.
The next digit of our result is 7. 
Result so far: 26381.272727
If we subtract 154 from 160, we 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.

On to step 13:
60 divided by 22 is 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 26381.2727272
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.

Advancing to step 14:
22 goes into 160 7 times with a remainder of 6.
The next digit of our result is 7. 
Result so far: 26381.27272727
Subtracting 154 from 160 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 26381.27272727, with a leftover of 6e-09.
