We divide 164099 by 45
We want to figure out the number of times 164099 can be divided by 45.

Moving on to step 1:
45 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 45

Step 2:
The number 45 fits into 16 0 times, leaving a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 45

Advancing to step 3:
The number 45 fits into 164 3 times, leaving a remainder of 29.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 135 from 164 leaves us with 29.
Append the next digit (0) from the dividend to 29 and continue with: 290 / 45

Moving on to step 4:
If we divide 290 by 45, we get 6 and a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
The remainder is 20 after subtracting 270 from 290.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 45

Advancing to step 5:
45 goes into 209 4 times with a remainder of 29.
Use 4 as the next digit of our solution. 
Result so far: 364.0
Deduct 180 from 209 and we're left with 29.
Include the next digit (9) from the dividend after 29, then repeat: 299 / 45

Let's proceed to step 6:
45 goes into 299 6 times with a remainder of 29.
Use 6 as the next digit of our solution. 
Result so far: 3646.0
Subtracting 270 from 299 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
290 divided by 45 is 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 3646.6
Subtract 270 from 290 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
When dividing 200 by 45, we get 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 3646.64
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
The number 45 fits into 200 4 times, leaving a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 3646.644
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 3646.644 with a remainder of 0.002.
