We divide 168151 by 45
We're looking to find how many times 45 goes into 168151.

On to step 1:
1 divided by 45 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 45

Moving on to step 2:
45 goes into 16 0 times with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 45

Let's proceed to step 3:
If we divide 168 by 45, we get 3 and a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 135 away from 168, we end up with 33.
Include the next digit (1) from the dividend after 33, then repeat: 331 / 45

Let's proceed to step 4:
The number 45 fits into 331 7 times, leaving a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
If we take 315 away from 331, we end up with 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 45

Let's proceed to step 5:
165 divided by 45 is 3 with a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 373.0
The remainder is 30 after subtracting 135 from 165.
Grab the next digit (1) from the dividend, add it to 30, then carry on: 301 / 45

Going ahead to step 6:
When dividing 301 by 45, we get 6 with a remainder of 31.
Use 6 as the next digit of our solution. 
Result so far: 3736.0
Deduct 270 from 301 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 7:
45 can be fit into 310 6 times, resulting in a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 3736.6
Subtracting 270 from 310 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.

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: 3736.68
The remainder is 40 after subtracting 360 from 400.
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 can be fit into 400 8 times, resulting in a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 3736.688
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 3736.688 with a remainder of 0.004.
