1518372 ÷ 668 
We want to figure out the number of times 1518372 can be divided by 668.

Step 1:
668 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 668

Let's proceed to step 2:
If we divide 15 by 668, we get 0 and a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 668

Advancing to step 3:
The number 668 fits into 151 0 times, leaving a remainder of 151.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 151 to get 151.
Include the next digit (8) from the dividend after 151, then repeat: 1518 / 668

On to step 4:
If we divide 1518 by 668, we get 2 and a remainder of 182.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 182 after subtracting 1336 from 1518.
Grab the next digit (3) from the dividend, add it to 182, then carry on: 1823 / 668

Let's proceed to step 5:
668 can be fit into 1823 2 times, resulting in a remainder of 487.
Write down 2 as next digit of the result. 
Result so far: 22.0
Deduct 1336 from 1823 and we're left with 487.
Take the next digit (7) from the dividend and append it to 487, then repeat: 4877 / 668

Moving on to step 6:
When dividing 4877 by 668, we get 7 with a remainder of 201.
Write down 7 as next digit of the result. 
Result so far: 227.0
Subtracting 4676 from 4877 leaves us with 201.
Append the next digit (2) from the dividend to 201 and continue with: 2012 / 668

Going ahead to step 7:
When dividing 2012 by 668, we get 3 with a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 2273.0
Subtract 2004 from 2012 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
If we divide 80 by 668, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 2273.0
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 9:
When dividing 800 by 668, we get 1 with a remainder of 132.
Use 1 as the next digit of our solution. 
Result so far: 2273.01
The remainder is 132 after subtracting 668 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 10:
The number 668 fits into 1320 1 times, leaving a remainder of 652.
Use 1 as the next digit of our solution. 
Result so far: 2273.011
The remainder is 652 after subtracting 668 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

The final outcome is 2273.011, with a leftover of 0.0652.
