3392173 ÷ 671 
We want to divide 3392173 by 671.

Let's proceed to step 1:
When dividing 3 by 671, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 671

Moving on to step 2:
33 divided by 671 is 0 with a remainder of 33.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 33, we get 33.
Bring next digit (9) of the dividend behind the 33 and repeat the process: 339 / 671

Step 3:
339 divided by 671 is 0 with a remainder of 339.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 339, we get 339.
Append the next digit (2) from the dividend to 339 and continue with: 3392 / 671

Step 4:
671 goes into 3392 5 times with a remainder of 37.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 3355 from 3392 to get 37.
Grab the next digit (1) from the dividend, add it to 37, then carry on: 371 / 671

On to step 5:
When dividing 371 by 671, we get 0 with a remainder of 371.
Put 0 as the next digit of the answer. 
Result so far: 50.0
If we take 0 away from 371, we end up with 371.
Append the next digit (7) from the dividend to 371 and continue with: 3717 / 671

Going ahead to step 6:
If we divide 3717 by 671, we get 5 and a remainder of 362.
Record the quotient 5 as the next digit in the result. 
Result so far: 505.0
Subtract 3355 from 3717 to get 362.
Include the next digit (3) from the dividend after 362, then repeat: 3623 / 671

Step 7:
When dividing 3623 by 671, we get 5 with a remainder of 268.
Write down 5 as next digit of the result. 
Result so far: 5055.0
Deduct 3355 from 3623 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Let's proceed to step 8:
The number 671 fits into 2680 3 times, leaving a remainder of 667.
Record the quotient 3 as the next digit in the result. 
Result so far: 5055.3
If we subtract 2013 from 2680, we get 667.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6670, and continue the process.

Going ahead to step 9:
6670 divided by 671 is 9 with a remainder of 631.
Put 9 as the next digit of the answer. 
Result so far: 5055.39
Subtract 6039 from 6670 to get 631.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

Step 10:
When dividing 6310 by 671, we get 9 with a remainder of 271.
Write down 9 as next digit of the result. 
Result so far: 5055.399
Subtracting 6039 from 6310 leaves us with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Our division results in 5055.399 with a remaining 0.0271.
