545186 divided by 678 
We want to figure out the number of times 545186 can be divided by 678.

Step 1:
5 divided by 678 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 678

Step 2:
When dividing 54 by 678, we get 0 with a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Append the next digit (5) from the dividend to 54 and continue with: 545 / 678

Going ahead to step 3:
545 divided by 678 is 0 with a remainder of 545.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 545, we get 545.
Fetch the next digit (1) from the dividend, attach it to 545 and continue: 5451 / 678

Let's proceed to step 4:
When dividing 5451 by 678, we get 8 with a remainder of 27.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 5424 from 5451 leaves us with 27.
Bring next digit (8) of the dividend behind the 27 and repeat the process: 278 / 678

Moving on to step 5:
678 can be fit into 278 0 times, resulting in a remainder of 278.
The next digit of our result is 0. 
Result so far: 80.0
Subtract 0 from 278 to get 278.
Fetch the next digit (6) from the dividend, attach it to 278 and continue: 2786 / 678

Advancing to step 6:
678 goes into 2786 4 times with a remainder of 74.
The next digit of our result is 4. 
Result so far: 804.0
Subtract 2712 from 2786 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 7:
The number 678 fits into 740 1 times, leaving a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 804.1
If we take 678 away from 740, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 8:
678 can be fit into 620 0 times, resulting in a remainder of 620.
Write down 0 as next digit of the result. 
Result so far: 804.1
Subtract 0 from 620 to get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Advancing to step 9:
678 can be fit into 6200 9 times, resulting in a remainder of 98.
The number 9 becomes the next digit in our result. 
Result so far: 804.109
Deduct 6102 from 6200 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 10:
When dividing 980 by 678, we get 1 with a remainder of 302.
Record the quotient 1 as the next digit in the result. 
Result so far: 804.1091
The remainder is 302 after subtracting 678 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Step 11:
678 goes into 3020 4 times with a remainder of 308.
Put 4 as the next digit of the answer. 
Result so far: 804.10914
Deduct 2712 from 3020 and we're left with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

On to step 12:
When dividing 3080 by 678, we get 4 with a remainder of 368.
Record the quotient 4 as the next digit in the result. 
Result so far: 804.109144
The remainder is 368 after subtracting 2712 from 3080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

The final result is 804.109144 with a remainder of 3.68e-05.
