We're dividing 40509870 by 175 
We're looking to find how many times 175 goes into 40509870.

Step 1:
4 divided by 175 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 175

Going ahead to step 2:
When dividing 40 by 175, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Bring next digit (5) of the dividend behind the 40 and repeat the process: 405 / 175

Advancing to step 3:
The number 175 fits into 405 2 times, leaving a remainder of 55.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 350 from 405 to get 55.
Include the next digit (0) from the dividend after 55, then repeat: 550 / 175

Step 4:
550 divided by 175 is 3 with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Deduct 525 from 550 and we're left with 25.
Append the next digit (9) from the dividend to 25 and continue with: 259 / 175

Step 5:
If we divide 259 by 175, we get 1 and a remainder of 84.
Put 1 as the next digit of the answer. 
Result so far: 231.0
If we subtract 175 from 259, we get 84.
Fetch the next digit (8) from the dividend, attach it to 84 and continue: 848 / 175

On to step 6:
848 divided by 175 is 4 with a remainder of 148.
Put 4 as the next digit of the answer. 
Result so far: 2314.0
Subtracting 700 from 848 leaves us with 148.
Include the next digit (7) from the dividend after 148, then repeat: 1487 / 175

On to step 7:
The number 175 fits into 1487 8 times, leaving a remainder of 87.
The number 8 becomes the next digit in our result. 
Result so far: 23148.0
Subtracting 1400 from 1487 leaves us with 87.
Grab the next digit (0) from the dividend, add it to 87, then carry on: 870 / 175

Moving on to step 8:
175 can be fit into 870 4 times, resulting in a remainder of 170.
The next digit of our result is 4. 
Result so far: 231484.0
The remainder is 170 after subtracting 700 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 9:
The number 175 fits into 1700 9 times, leaving a remainder of 125.
Record the quotient 9 as the next digit in the result. 
Result so far: 231484.9
Subtract 1575 from 1700 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 10:
175 goes into 1250 7 times with a remainder of 25.
Write down 7 as next digit of the result. 
Result so far: 231484.97
Subtract 1225 from 1250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 11:
175 can be fit into 250 1 times, resulting in a remainder of 75.
Record the quotient 1 as the next digit in the result. 
Result so far: 231484.971
Subtract 175 from 250 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 12:
750 divided by 175 is 4 with a remainder of 50.
Record the quotient 4 as the next digit in the result. 
Result so far: 231484.9714
Deduct 700 from 750 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 13:
When dividing 500 by 175, we get 2 with a remainder of 150.
Record the quotient 2 as the next digit in the result. 
Result so far: 231484.97142
If we subtract 350 from 500, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 14:
175 goes into 1500 8 times with a remainder of 100.
Record the quotient 8 as the next digit in the result. 
Result so far: 231484.971428
The remainder is 100 after subtracting 1400 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 15:
If we divide 1000 by 175, we get 5 and a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 231484.9714285
Subtract 875 from 1000 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 16:
The number 175 fits into 1250 7 times, leaving a remainder of 25.
The number 7 becomes the next digit in our result. 
Result so far: 231484.97142857
Deduct 1225 from 1250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 231484.97142857 with a remaining 2.5e-08.
