4349694 ÷ 678 
Our goal is to divide 4349694 by 678.

Step 1:
678 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 678

On to step 2:
When dividing 43 by 678, we get 0 with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Take the next digit (4) from the dividend and append it to 43, then repeat: 434 / 678

Going ahead to step 3:
434 divided by 678 is 0 with a remainder of 434.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 434 and we're left with 434.
Append the next digit (9) from the dividend to 434 and continue with: 4349 / 678

Let's proceed to step 4:
The number 678 fits into 4349 6 times, leaving a remainder of 281.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 4068 from 4349 leaves us with 281.
Grab the next digit (6) from the dividend, add it to 281, then carry on: 2816 / 678

Step 5:
The number 678 fits into 2816 4 times, leaving a remainder of 104.
Put 4 as the next digit of the answer. 
Result so far: 64.0
If we take 2712 away from 2816, we end up with 104.
Append the next digit (9) from the dividend to 104 and continue with: 1049 / 678

Let's proceed to step 6:
678 can be fit into 1049 1 times, resulting in a remainder of 371.
Write down 1 as next digit of the result. 
Result so far: 641.0
Subtract 678 from 1049 to get 371.
Fetch the next digit (4) from the dividend, attach it to 371 and continue: 3714 / 678

Step 7:
The number 678 fits into 3714 5 times, leaving a remainder of 324.
Write down 5 as next digit of the result. 
Result so far: 6415.0
Deduct 3390 from 3714 and we're left with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Step 8:
When dividing 3240 by 678, we get 4 with a remainder of 528.
Use 4 as the next digit of our solution. 
Result so far: 6415.4
The remainder is 528 after subtracting 2712 from 3240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Moving on to step 9:
If we divide 5280 by 678, we get 7 and a remainder of 534.
Put 7 as the next digit of the answer. 
Result so far: 6415.47
Subtract 4746 from 5280 to get 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Let's proceed to step 10:
If we divide 5340 by 678, we get 7 and a remainder of 594.
Write down 7 as next digit of the result. 
Result so far: 6415.477
If we take 4746 away from 5340, we end up with 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

The quotient of the division is 6415.477, and the remainder is 0.0594.
