We look at the division of 43860162 by 678 
We're looking to find how many times 678 goes into 43860162.

Advancing to step 1:
The number 678 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 678

Step 2:
43 divided by 678 is 0 with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Grab the next digit (8) from the dividend, add it to 43, then carry on: 438 / 678

Moving on to step 3:
The number 678 fits into 438 0 times, leaving a remainder of 438.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 438 and we're left with 438.
Bring next digit (6) of the dividend behind the 438 and repeat the process: 4386 / 678

Advancing to step 4:
678 can be fit into 4386 6 times, resulting in a remainder of 318.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 318 after subtracting 4068 from 4386.
Fetch the next digit (0) from the dividend, attach it to 318 and continue: 3180 / 678

Advancing to step 5:
678 can be fit into 3180 4 times, resulting in a remainder of 468.
Write down 4 as next digit of the result. 
Result so far: 64.0
Subtract 2712 from 3180 to get 468.
Include the next digit (1) from the dividend after 468, then repeat: 4681 / 678

Advancing to step 6:
The number 678 fits into 4681 6 times, leaving a remainder of 613.
Record the quotient 6 as the next digit in the result. 
Result so far: 646.0
Subtract 4068 from 4681 to get 613.
Include the next digit (6) from the dividend after 613, then repeat: 6136 / 678

On to step 7:
When dividing 6136 by 678, we get 9 with a remainder of 34.
Write down 9 as next digit of the result. 
Result so far: 6469.0
If we subtract 6102 from 6136, we get 34.
Take the next digit (2) from the dividend and append it to 34, then repeat: 342 / 678

Advancing to step 8:
If we divide 342 by 678, we get 0 and a remainder of 342.
Use 0 as the next digit of our solution. 
Result so far: 64690.0
If we subtract 0 from 342, we get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Let's proceed to step 9:
3420 divided by 678 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 64690.5
Subtracting 3390 from 3420 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
678 goes into 300 0 times with a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 64690.5
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 11:
678 can be fit into 3000 4 times, resulting in a remainder of 288.
Put 4 as the next digit of the answer. 
Result so far: 64690.504
Deduct 2712 from 3000 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 12:
If we divide 2880 by 678, we get 4 and a remainder of 168.
The number 4 becomes the next digit in our result. 
Result so far: 64690.5044
Subtracting 2712 from 2880 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The quotient of the division is 64690.5044, and the remainder is 0.00168.
