668455 ÷ 22 
Our goal is to divide 668455 by 22.

On to step 1:
22 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 22

Going ahead to step 2:
22 goes into 66 3 times with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 66 from 66 to get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 22

Moving on to step 3:
8 divided by 22 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 22

Let's proceed to step 4:
If we divide 84 by 22, we get 3 and a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 303.0
Subtracting 66 from 84 leaves us with 18.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 22

Going ahead to step 5:
When dividing 185 by 22, we get 8 with a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 3038.0
Subtract 176 from 185 to get 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 22

On to step 6:
95 divided by 22 is 4 with a remainder of 7.
The next digit of our result is 4. 
Result so far: 30384.0
If we subtract 88 from 95, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
If we divide 70 by 22, we get 3 and a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 30384.3
Subtracting 66 from 70 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
If we divide 40 by 22, we get 1 and a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 30384.31
Deduct 22 from 40 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
If we divide 180 by 22, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 30384.318
Subtracting 176 from 180 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
If we divide 40 by 22, we get 1 and a remainder of 18.
The next digit of our result is 1. 
Result so far: 30384.3181
If we take 22 away from 40, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
180 divided by 22 is 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 30384.31818
Subtract 176 from 180 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
22 can be fit into 40 1 times, resulting in a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 30384.318181
Subtracting 22 from 40 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 13:
180 divided by 22 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 30384.3181818
If we take 176 away from 180, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
40 divided by 22 is 1 with a remainder of 18.
The next digit of our result is 1. 
Result so far: 30384.31818181
The remainder is 18 after subtracting 22 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 30384.31818181, with a leftover of 1.8e-08.
