We divide 168178 by 45
We're looking to find how many times 45 goes into 168178.

Moving on to step 1:
If we divide 1 by 45, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 45

Going ahead to step 2:
When dividing 16 by 45, we get 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 45

On to step 3:
45 goes into 168 3 times with a remainder of 33.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 135 from 168, we get 33.
Include the next digit (1) from the dividend after 33, then repeat: 331 / 45

Let's proceed to step 4:
45 can be fit into 331 7 times, resulting in a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Deduct 315 from 331 and we're left with 16.
Include the next digit (7) from the dividend after 16, then repeat: 167 / 45

Let's proceed to step 5:
167 divided by 45 is 3 with a remainder of 32.
Use 3 as the next digit of our solution. 
Result so far: 373.0
Subtract 135 from 167 to get 32.
Bring next digit (8) of the dividend behind the 32 and repeat the process: 328 / 45

Step 6:
328 divided by 45 is 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 3737.0
If we subtract 315 from 328, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
The number 45 fits into 130 2 times, leaving a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 3737.2
The remainder is 40 after subtracting 90 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
When dividing 400 by 45, we get 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 3737.28
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
45 goes into 400 8 times with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 3737.288
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 3737.288 and a remainder of 0.004.
