15305106 ÷ 678 
We want to divide 15305106 by 678.

Going ahead to step 1:
If we divide 1 by 678, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 678

Let's proceed to step 2:
If we divide 15 by 678, we get 0 and a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 678

Step 3:
153 divided by 678 is 0 with a remainder of 153.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 153 after subtracting 0 from 153.
Fetch the next digit (0) from the dividend, attach it to 153 and continue: 1530 / 678

Advancing to step 4:
678 can be fit into 1530 2 times, resulting in a remainder of 174.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1356 from 1530, we get 174.
Fetch the next digit (5) from the dividend, attach it to 174 and continue: 1745 / 678

Moving on to step 5:
1745 divided by 678 is 2 with a remainder of 389.
The next digit of our result is 2. 
Result so far: 22.0
The remainder is 389 after subtracting 1356 from 1745.
Append the next digit (1) from the dividend to 389 and continue with: 3891 / 678

Let's proceed to step 6:
If we divide 3891 by 678, we get 5 and a remainder of 501.
The number 5 becomes the next digit in our result. 
Result so far: 225.0
If we subtract 3390 from 3891, we get 501.
Take the next digit (0) from the dividend and append it to 501, then repeat: 5010 / 678

On to step 7:
678 can be fit into 5010 7 times, resulting in a remainder of 264.
Write down 7 as next digit of the result. 
Result so far: 2257.0
Deduct 4746 from 5010 and we're left with 264.
Take the next digit (6) from the dividend and append it to 264, then repeat: 2646 / 678

Going ahead to step 8:
678 can be fit into 2646 3 times, resulting in a remainder of 612.
Write down 3 as next digit of the result. 
Result so far: 22573.0
Subtracting 2034 from 2646 leaves us with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Moving on to step 9:
6120 divided by 678 is 9 with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 22573.9
If we take 6102 away from 6120, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
If we divide 180 by 678, we get 0 and a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 22573.9
If we subtract 0 from 180, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 11:
1800 divided by 678 is 2 with a remainder of 444.
The number 2 becomes the next digit in our result. 
Result so far: 22573.902
If we take 1356 away from 1800, we end up with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Step 12:
The number 678 fits into 4440 6 times, leaving a remainder of 372.
Use 6 as the next digit of our solution. 
Result so far: 22573.9026
If we subtract 4068 from 4440, we get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Moving on to step 13:
678 can be fit into 3720 5 times, resulting in a remainder of 330.
Record the quotient 5 as the next digit in the result. 
Result so far: 22573.90265
If we take 3390 away from 3720, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 14:
If we divide 3300 by 678, we get 4 and a remainder of 588.
The number 4 becomes the next digit in our result. 
Result so far: 22573.902654
Deduct 2712 from 3300 and we're left with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Step 15:
5880 divided by 678 is 8 with a remainder of 456.
The number 8 becomes the next digit in our result. 
Result so far: 22573.9026548
Subtracting 5424 from 5880 leaves us with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Step 16:
If we divide 4560 by 678, we get 6 and a remainder of 492.
The number 6 becomes the next digit in our result. 
Result so far: 22573.90265486
If we take 4068 away from 4560, we end up with 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

In conclusion, the division gives 22573.90265486 with a balance of 4.92e-07.
