16980385 divided by 678 
We want to figure out the number of times 16980385 can be divided by 678.

Let's proceed to step 1:
678 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 678

Let's proceed to step 2:
678 can be fit into 16 0 times, resulting in a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 678

Let's proceed to step 3:
When dividing 169 by 678, we get 0 with a remainder of 169.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 169 and we're left with 169.
Bring next digit (8) of the dividend behind the 169 and repeat the process: 1698 / 678

Moving on to step 4:
678 can be fit into 1698 2 times, resulting in a remainder of 342.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 342 after subtracting 1356 from 1698.
Fetch the next digit (0) from the dividend, attach it to 342 and continue: 3420 / 678

Moving on to step 5:
If we divide 3420 by 678, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we subtract 3390 from 3420, we get 30.
Include the next digit (3) from the dividend after 30, then repeat: 303 / 678

Going ahead to step 6:
When dividing 303 by 678, we get 0 with a remainder of 303.
Write down 0 as next digit of the result. 
Result so far: 250.0
The remainder is 303 after subtracting 0 from 303.
Fetch the next digit (8) from the dividend, attach it to 303 and continue: 3038 / 678

Going ahead to step 7:
678 goes into 3038 4 times with a remainder of 326.
Write down 4 as next digit of the result. 
Result so far: 2504.0
Deduct 2712 from 3038 and we're left with 326.
Append the next digit (5) from the dividend to 326 and continue with: 3265 / 678

Going ahead to step 8:
678 goes into 3265 4 times with a remainder of 553.
Write down 4 as next digit of the result. 
Result so far: 25044.0
If we take 2712 away from 3265, we end up with 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Moving on to step 9:
678 can be fit into 5530 8 times, resulting in a remainder of 106.
Use 8 as the next digit of our solution. 
Result so far: 25044.8
Subtracting 5424 from 5530 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 10:
If we divide 1060 by 678, we get 1 and a remainder of 382.
The number 1 becomes the next digit in our result. 
Result so far: 25044.81
The remainder is 382 after subtracting 678 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

On to step 11:
The number 678 fits into 3820 5 times, leaving a remainder of 430.
Use 5 as the next digit of our solution. 
Result so far: 25044.815
The remainder is 430 after subtracting 3390 from 3820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Moving on to step 12:
When dividing 4300 by 678, we get 6 with a remainder of 232.
Write down 6 as next digit of the result. 
Result so far: 25044.8156
If we subtract 4068 from 4300, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

On to step 13:
678 goes into 2320 3 times with a remainder of 286.
The number 3 becomes the next digit in our result. 
Result so far: 25044.81563
Subtract 2034 from 2320 to get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

On to step 14:
678 can be fit into 2860 4 times, resulting in a remainder of 148.
Record the quotient 4 as the next digit in the result. 
Result so far: 25044.815634
If we subtract 2712 from 2860, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Going ahead to step 15:
If we divide 1480 by 678, we get 2 and a remainder of 124.
The next digit of our result is 2. 
Result so far: 25044.8156342
Subtract 1356 from 1480 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 16:
1240 divided by 678 is 1 with a remainder of 562.
The next digit of our result is 1. 
Result so far: 25044.81563421
Subtract 678 from 1240 to get 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

In conclusion, the division gives 25044.81563421 with a balance of 5.62e-07.
