164145 divided by 45 
Let's see how many times 45 fits into 164145.

Step 1:
If we divide 1 by 45, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 45

Advancing to step 2:
If we divide 16 by 45, we get 0 and a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 45

Moving on to step 3:
If we divide 164 by 45, we get 3 and a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 29 after subtracting 135 from 164.
Fetch the next digit (1) from the dividend, attach it to 29 and continue: 291 / 45

Step 4:
The number 45 fits into 291 6 times, leaving a remainder of 21.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
The remainder is 21 after subtracting 270 from 291.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 45

On to step 5:
When dividing 214 by 45, we get 4 with a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 364.0
Subtracting 180 from 214 leaves us with 34.
Append the next digit (5) from the dividend to 34 and continue with: 345 / 45

On to step 6:
345 divided by 45 is 7 with a remainder of 30.
The next digit of our result is 7. 
Result so far: 3647.0
Subtract 315 from 345 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 7:
300 divided by 45 is 6 with a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 3647.6
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
300 divided by 45 is 6 with a remainder of 30.
The next digit of our result is 6. 
Result so far: 3647.66
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 3647.66 and a remainder of 0.03.
