We're dividing 355175 by 40 
We want to divide 355175 by 40.

Let's proceed to step 1:
When dividing 3 by 40, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 40

Let's proceed to step 2:
40 can be fit into 35 0 times, resulting in a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Append the next digit (5) from the dividend to 35 and continue with: 355 / 40

Advancing to step 3:
When dividing 355 by 40, we get 8 with a remainder of 35.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 320 from 355 to get 35.
Grab the next digit (1) from the dividend, add it to 35, then carry on: 351 / 40

Going ahead to step 4:
40 goes into 351 8 times with a remainder of 31.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
Subtracting 320 from 351 leaves us with 31.
Grab the next digit (7) from the dividend, add it to 31, then carry on: 317 / 40

Going ahead to step 5:
When dividing 317 by 40, we get 7 with a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 887.0
Subtract 280 from 317 to get 37.
Take the next digit (5) from the dividend and append it to 37, then repeat: 375 / 40

Step 6:
40 can be fit into 375 9 times, resulting in a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 8879.0
Subtracting 360 from 375 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.

Going ahead to step 7:
The number 40 fits into 150 3 times, leaving a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 8879.3
If we subtract 120 from 150, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
When dividing 300 by 40, we get 7 with a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 8879.37
Subtract 280 from 300 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
40 goes into 200 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 8879.375
Deduct 200 from 200 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
If we divide 0 by 40, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8879.375
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8879.375
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 8879.375 and a remainder of 0.0.
