We look at the division of 668515 by 22 
We want to figure out the number of times 668515 can be divided by 22.

On to step 1:
22 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 22

On to step 2:
The number 22 fits into 66 3 times, leaving a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 0 after subtracting 66 from 66.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 22

Moving on to step 3:
When dividing 8 by 22, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 22

Moving on to step 4:
When dividing 85 by 22, we get 3 with a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 303.0
Subtract 66 from 85 to get 19.
Fetch the next digit (1) from the dividend, attach it to 19 and continue: 191 / 22

Let's proceed to step 5:
The number 22 fits into 191 8 times, leaving a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 3038.0
If we take 176 away from 191, we end up with 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 22

Step 6:
The number 22 fits into 155 7 times, leaving a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 30387.0
Subtracting 154 from 155 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
If we divide 10 by 22, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 30387.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
If we divide 100 by 22, we get 4 and a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 30387.04
Deduct 88 from 100 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
22 goes into 120 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 30387.045
If we subtract 110 from 120, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
If we divide 100 by 22, we get 4 and a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 30387.0454
The remainder is 12 after subtracting 88 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
The number 22 fits into 120 5 times, leaving a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 30387.04545
Subtract 110 from 120 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
22 can be fit into 100 4 times, resulting in a remainder of 12.
The next digit of our result is 4. 
Result so far: 30387.045454
Subtracting 88 from 100 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
If we divide 120 by 22, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 30387.0454545
Subtracting 110 from 120 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 14:
22 can be fit into 100 4 times, resulting in a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 30387.04545454
If we subtract 88 from 100, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 30387.04545454 with a remainder of 1.2e-08.
