We divide 161670 by 45
We want to figure out the number of times 161670 can be divided by 45.

Advancing to step 1:
If we divide 1 by 45, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 45

Moving on to step 2:
45 goes into 16 0 times with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 45

Moving on to step 3:
45 goes into 161 3 times with a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 135 from 161, we get 26.
Append the next digit (6) from the dividend to 26 and continue with: 266 / 45

Let's proceed to step 4:
When dividing 266 by 45, we get 5 with a remainder of 41.
Put 5 as the next digit of the answer. 
Result so far: 35.0
The remainder is 41 after subtracting 225 from 266.
Include the next digit (7) from the dividend after 41, then repeat: 417 / 45

Going ahead to step 5:
The number 45 fits into 417 9 times, leaving a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 359.0
Deduct 405 from 417 and we're left with 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 45

Let's proceed to step 6:
45 goes into 120 2 times with a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 3592.0
The remainder is 30 after subtracting 90 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 7:
45 goes into 300 6 times with a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 3592.6
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:
45 can be fit into 300 6 times, resulting in a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 3592.66
If we subtract 270 from 300, we 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.

The quotient of the division is 3592.66, and the remainder is 0.03.
