168989 divided by 45 
Let's see how many times 45 fits into 168989.

Advancing to step 1:
45 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 45

Advancing to step 2:
When dividing 16 by 45, we get 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 45

Advancing to step 3:
When dividing 168 by 45, we get 3 with a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 135 from 168 to get 33.
Include the next digit (9) from the dividend after 33, then repeat: 339 / 45

Advancing to step 4:
339 divided by 45 is 7 with a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Subtracting 315 from 339 leaves us with 24.
Bring next digit (8) of the dividend behind the 24 and repeat the process: 248 / 45

Advancing to step 5:
The number 45 fits into 248 5 times, leaving a remainder of 23.
Write down 5 as next digit of the result. 
Result so far: 375.0
The remainder is 23 after subtracting 225 from 248.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 45

Moving on to step 6:
45 goes into 239 5 times with a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 3755.0
Subtract 225 from 239 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
When dividing 140 by 45, we get 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 3755.3
If we subtract 135 from 140, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
45 can be fit into 50 1 times, resulting in a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 3755.31
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
45 goes into 50 1 times with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 3755.311
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 3755.311 and a remainder of 0.0005.
