Let's divide 8485840 by 671
We're looking to find how many times 671 goes into 8485840.

Let's proceed to step 1:
When dividing 8 by 671, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 671

On to step 2:
When dividing 84 by 671, we get 0 with a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Include the next digit (8) from the dividend after 84, then repeat: 848 / 671

Step 3:
671 can be fit into 848 1 times, resulting in a remainder of 177.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 671 away from 848, we end up with 177.
Grab the next digit (5) from the dividend, add it to 177, then carry on: 1775 / 671

On to step 4:
When dividing 1775 by 671, we get 2 with a remainder of 433.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 1342 away from 1775, we end up with 433.
Append the next digit (8) from the dividend to 433 and continue with: 4338 / 671

On to step 5:
671 goes into 4338 6 times with a remainder of 312.
Record the quotient 6 as the next digit in the result. 
Result so far: 126.0
The remainder is 312 after subtracting 4026 from 4338.
Take the next digit (4) from the dividend and append it to 312, then repeat: 3124 / 671

On to step 6:
If we divide 3124 by 671, we get 4 and a remainder of 440.
The number 4 becomes the next digit in our result. 
Result so far: 1264.0
Subtracting 2684 from 3124 leaves us with 440.
Take the next digit (0) from the dividend and append it to 440, then repeat: 4400 / 671

Let's proceed to step 7:
4400 divided by 671 is 6 with a remainder of 374.
Put 6 as the next digit of the answer. 
Result so far: 12646.0
Subtracting 4026 from 4400 leaves us with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Going ahead to step 8:
671 goes into 3740 5 times with a remainder of 385.
The next digit of our result is 5. 
Result so far: 12646.5
The remainder is 385 after subtracting 3355 from 3740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Step 9:
671 goes into 3850 5 times with a remainder of 495.
The number 5 becomes the next digit in our result. 
Result so far: 12646.55
Subtracting 3355 from 3850 leaves us with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

The quotient of the division is 12646.55, and the remainder is 0.495.
