408931 divided by 22 
Our goal is to divide 408931 by 22.

Let's proceed to step 1:
The number 22 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 22

Going ahead to step 2:
22 goes into 40 1 times with a remainder of 18.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 22 from 40 to get 18.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 22

Step 3:
The number 22 fits into 188 8 times, leaving a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 176 from 188 to get 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 22

Step 4:
The number 22 fits into 129 5 times, leaving a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 185.0
Subtract 110 from 129 to get 19.
Bring next digit (3) of the dividend behind the 19 and repeat the process: 193 / 22

Step 5:
193 divided by 22 is 8 with a remainder of 17.
The number 8 becomes the next digit in our result. 
Result so far: 1858.0
Subtracting 176 from 193 leaves us with 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 22

Step 6:
The number 22 fits into 171 7 times, leaving a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 18587.0
If we take 154 away from 171, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
The number 22 fits into 170 7 times, leaving a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 18587.7
Subtracting 154 from 170 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:
22 goes into 160 7 times with a remainder of 6.
The next digit of our result is 7. 
Result so far: 18587.77
Deduct 154 from 160 and we're left 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 18587.77, with a leftover of 0.006.
