We're dividing 670243 by 75 
We're looking to find how many times 75 goes into 670243.

Advancing to step 1:
If we divide 6 by 75, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 75

Advancing to step 2:
When dividing 67 by 75, we get 0 with a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Take the next digit (0) from the dividend and append it to 67, then repeat: 670 / 75

Advancing to step 3:
670 divided by 75 is 8 with a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 600 from 670 to get 70.
Bring next digit (2) of the dividend behind the 70 and repeat the process: 702 / 75

Step 4:
702 divided by 75 is 9 with a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 89.0
Deduct 675 from 702 and we're left with 27.
Fetch the next digit (4) from the dividend, attach it to 27 and continue: 274 / 75

On to step 5:
75 goes into 274 3 times with a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 893.0
The remainder is 49 after subtracting 225 from 274.
Fetch the next digit (3) from the dividend, attach it to 49 and continue: 493 / 75

Going ahead to step 6:
75 can be fit into 493 6 times, resulting in a remainder of 43.
Record the quotient 6 as the next digit in the result. 
Result so far: 8936.0
Subtracting 450 from 493 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 7:
When dividing 430 by 75, we get 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 8936.5
Subtract 375 from 430 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 8:
75 can be fit into 550 7 times, resulting in a remainder of 25.
Record the quotient 7 as the next digit in the result. 
Result so far: 8936.57
Subtract 525 from 550 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.

Moving on to step 9:
When dividing 250 by 75, we get 3 with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 8936.573
Deduct 225 from 250 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.

Step 10:
250 divided by 75 is 3 with a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 8936.5733
If we subtract 225 from 250, we 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.

After the division, we end up with 8936.5733 and a remainder of 0.00025.
