We divide 356580 by 45
We want to figure out the number of times 356580 can be divided by 45.

Advancing to step 1:
If we divide 3 by 45, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 45

Going ahead to step 2:
45 goes into 35 0 times with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Bring next digit (6) of the dividend behind the 35 and repeat the process: 356 / 45

Going ahead to step 3:
When dividing 356 by 45, we get 7 with a remainder of 41.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 315 from 356 leaves us with 41.
Include the next digit (5) from the dividend after 41, then repeat: 415 / 45

Going ahead to step 4:
The number 45 fits into 415 9 times, leaving a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
Subtract 405 from 415 to get 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 45

Let's proceed to step 5:
45 can be fit into 108 2 times, resulting in a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 792.0
Subtract 90 from 108 to get 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 45

Step 6:
The number 45 fits into 180 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 7924.0
Subtract 180 from 180 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.

On to step 7:
45 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7924.0
Subtracting 0 from 0 leaves us 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.

Moving on to step 8:
0 divided by 45 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7924.0
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 7924.0, with a leftover of 0.0.
