446091 ÷ 45 
We're looking to find how many times 45 goes into 446091.

On to step 1:
4 divided by 45 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 45

Step 2:
If we divide 44 by 45, we get 0 and a remainder of 44.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 44, we get 44.
Append the next digit (6) from the dividend to 44 and continue with: 446 / 45

Advancing to step 3:
45 goes into 446 9 times with a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 405 from 446 to get 41.
Append the next digit (0) from the dividend to 41 and continue with: 410 / 45

Step 4:
When dividing 410 by 45, we get 9 with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
Subtract 405 from 410 to get 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 45

Step 5:
If we divide 59 by 45, we get 1 and a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 991.0
The remainder is 14 after subtracting 45 from 59.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 45

Let's proceed to step 6:
When dividing 141 by 45, we get 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 9913.0
Subtracting 135 from 141 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
60 divided by 45 is 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 9913.1
Deduct 45 from 60 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
45 goes into 150 3 times with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 9913.13
Deduct 135 from 150 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
If we divide 150 by 45, we get 3 and a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 9913.133
Subtracting 135 from 150 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 9913.133 with a remaining 0.0015.
