We look at the division of 16206254 by 678 
Let's see how many times 678 fits into 16206254.

Step 1:
When dividing 1 by 678, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 678

Moving on to step 2:
678 goes into 16 0 times with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Take the next digit (2) from the dividend and append it to 16, then repeat: 162 / 678

Moving on to step 3:
When dividing 162 by 678, we get 0 with a remainder of 162.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 162 leaves us with 162.
Fetch the next digit (0) from the dividend, attach it to 162 and continue: 1620 / 678

Step 4:
678 goes into 1620 2 times with a remainder of 264.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1356 from 1620 to get 264.
Take the next digit (6) from the dividend and append it to 264, then repeat: 2646 / 678

Step 5:
2646 divided by 678 is 3 with a remainder of 612.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtracting 2034 from 2646 leaves us with 612.
Grab the next digit (2) from the dividend, add it to 612, then carry on: 6122 / 678

Let's proceed to step 6:
When dividing 6122 by 678, we get 9 with a remainder of 20.
The next digit of our result is 9. 
Result so far: 239.0
If we subtract 6102 from 6122, we get 20.
Take the next digit (5) from the dividend and append it to 20, then repeat: 205 / 678

Moving on to step 7:
678 can be fit into 205 0 times, resulting in a remainder of 205.
Record the quotient 0 as the next digit in the result. 
Result so far: 2390.0
Deduct 0 from 205 and we're left with 205.
Take the next digit (4) from the dividend and append it to 205, then repeat: 2054 / 678

Advancing to step 8:
678 can be fit into 2054 3 times, resulting in a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 23903.0
If we take 2034 away from 2054, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
678 can be fit into 200 0 times, resulting in a remainder of 200.
The next digit of our result is 0. 
Result so far: 23903.0
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 10:
678 goes into 2000 2 times with a remainder of 644.
Record the quotient 2 as the next digit in the result. 
Result so far: 23903.02
Deduct 1356 from 2000 and we're left with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

On to step 11:
6440 divided by 678 is 9 with a remainder of 338.
The number 9 becomes the next digit in our result. 
Result so far: 23903.029
If we take 6102 away from 6440, we end up with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Let's proceed to step 12:
678 can be fit into 3380 4 times, resulting in a remainder of 668.
Put 4 as the next digit of the answer. 
Result so far: 23903.0294
Deduct 2712 from 3380 and we're left with 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

Going ahead to step 13:
The number 678 fits into 6680 9 times, leaving a remainder of 578.
The next digit of our result is 9. 
Result so far: 23903.02949
Subtracting 6102 from 6680 leaves us with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

On to step 14:
The number 678 fits into 5780 8 times, leaving a remainder of 356.
The number 8 becomes the next digit in our result. 
Result so far: 23903.029498
Deduct 5424 from 5780 and we're left with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Going ahead to step 15:
If we divide 3560 by 678, we get 5 and a remainder of 170.
The next digit of our result is 5. 
Result so far: 23903.0294985
The remainder is 170 after subtracting 3390 from 3560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 16:
The number 678 fits into 1700 2 times, leaving a remainder of 344.
Record the quotient 2 as the next digit in the result. 
Result so far: 23903.02949852
If we subtract 1356 from 1700, we get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

In conclusion, the division gives 23903.02949852 with a balance of 3.44e-07.
