168936 ÷ 45 
We want to figure out the number of times 168936 can be divided by 45.

Going ahead to step 1:
1 divided by 45 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 45

Advancing to step 2:
45 can be fit into 16 0 times, resulting in a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 45

Moving on to step 3:
45 goes into 168 3 times with a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 135 from 168 and we're left with 33.
Include the next digit (9) from the dividend after 33, then repeat: 339 / 45

Moving on to step 4:
45 goes into 339 7 times with a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 37.0
If we subtract 315 from 339, we get 24.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 45

Let's proceed to step 5:
When dividing 243 by 45, we get 5 with a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 375.0
Subtracting 225 from 243 leaves us with 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 45

On to step 6:
If we divide 186 by 45, we get 4 and a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 3754.0
If we subtract 180 from 186, we get 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:
45 goes into 60 1 times with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 3754.1
If we subtract 45 from 60, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 8:
When dividing 150 by 45, we get 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 3754.13
Subtract 135 from 150 to get 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 9:
150 divided by 45 is 3 with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 3754.133
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.

In conclusion, the division gives 3754.133 with a balance of 0.0015.
