We divide 665919 by 45
We want to figure out the number of times 665919 can be divided by 45.

Moving on to step 1:
6 divided by 45 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 45

On to step 2:
45 can be fit into 66 1 times, resulting in a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 45 away from 66, we end up with 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 45

Let's proceed to step 3:
45 can be fit into 215 4 times, resulting in a remainder of 35.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 180 from 215, we get 35.
Append the next digit (9) from the dividend to 35 and continue with: 359 / 45

On to step 4:
When dividing 359 by 45, we get 7 with a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 147.0
If we take 315 away from 359, we end up with 44.
Fetch the next digit (1) from the dividend, attach it to 44 and continue: 441 / 45

Step 5:
441 divided by 45 is 9 with a remainder of 36.
Use 9 as the next digit of our solution. 
Result so far: 1479.0
If we subtract 405 from 441, we get 36.
Fetch the next digit (9) from the dividend, attach it to 36 and continue: 369 / 45

Moving on to step 6:
If we divide 369 by 45, we get 8 and a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 14798.0
Subtracting 360 from 369 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
45 can be fit into 90 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 14798.2
Deduct 90 from 90 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
0 divided by 45 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 14798.2
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
45 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 14798.2
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 14798.2, with a leftover of 0.0.
