4086066 ÷ 678 
Let's see how many times 678 fits into 4086066.

Moving on to step 1:
4 divided by 678 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 678

Let's proceed to step 2:
678 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 678

Going ahead to step 3:
If we divide 408 by 678, we get 0 and a remainder of 408.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 408 to get 408.
Bring next digit (6) of the dividend behind the 408 and repeat the process: 4086 / 678

Going ahead to step 4:
4086 divided by 678 is 6 with a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 4068 from 4086 and we're left with 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 678

Going ahead to step 5:
When dividing 180 by 678, we get 0 with a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 60.0
If we take 0 away from 180, we end up with 180.
Bring next digit (6) of the dividend behind the 180 and repeat the process: 1806 / 678

Advancing to step 6:
The number 678 fits into 1806 2 times, leaving a remainder of 450.
The next digit of our result is 2. 
Result so far: 602.0
Subtracting 1356 from 1806 leaves us with 450.
Include the next digit (6) from the dividend after 450, then repeat: 4506 / 678

Let's proceed to step 7:
4506 divided by 678 is 6 with a remainder of 438.
Write down 6 as next digit of the result. 
Result so far: 6026.0
Subtract 4068 from 4506 to get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Step 8:
4380 divided by 678 is 6 with a remainder of 312.
The next digit of our result is 6. 
Result so far: 6026.6
Subtract 4068 from 4380 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Let's proceed to step 9:
678 goes into 3120 4 times with a remainder of 408.
Use 4 as the next digit of our solution. 
Result so far: 6026.64
Subtracting 2712 from 3120 leaves us with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Let's proceed to step 10:
If we divide 4080 by 678, we get 6 and a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 6026.646
If we take 4068 away from 4080, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
The number 678 fits into 120 0 times, leaving a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 6026.646
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 12:
The number 678 fits into 1200 1 times, leaving a remainder of 522.
Put 1 as the next digit of the answer. 
Result so far: 6026.64601
The remainder is 522 after subtracting 678 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Going ahead to step 13:
678 can be fit into 5220 7 times, resulting in a remainder of 474.
The next digit of our result is 7. 
Result so far: 6026.646017
If we take 4746 away from 5220, we end up with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Advancing to step 14:
If we divide 4740 by 678, we get 6 and a remainder of 672.
Record the quotient 6 as the next digit in the result. 
Result so far: 6026.6460176
Deduct 4068 from 4740 and we're left with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

On to step 15:
678 can be fit into 6720 9 times, resulting in a remainder of 618.
Use 9 as the next digit of our solution. 
Result so far: 6026.64601769
Subtract 6102 from 6720 to get 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

The quotient of the division is 6026.64601769, and the remainder is 6.18e-07.
