667420 divided by 45 
Our goal is to divide 667420 by 45.

Going ahead to step 1:
The number 45 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 45

Step 2:
45 goes into 66 1 times with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 21 after subtracting 45 from 66.
Include the next digit (7) from the dividend after 21, then repeat: 217 / 45

Going ahead to step 3:
If we divide 217 by 45, we get 4 and a remainder of 37.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 180 from 217 leaves us with 37.
Include the next digit (4) from the dividend after 37, then repeat: 374 / 45

Step 4:
374 divided by 45 is 8 with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 148.0
If we subtract 360 from 374, we get 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 45

Step 5:
142 divided by 45 is 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 1483.0
Subtract 135 from 142 to get 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 45

On to step 6:
When dividing 70 by 45, we get 1 with a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 14831.0
Subtract 45 from 70 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 7:
45 can be fit into 250 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 14831.5
If we subtract 225 from 250, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 8:
45 can be fit into 250 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 14831.55
Subtracting 225 from 250 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 14831.55, with a leftover of 0.025.
