We divide 28658678 by 1
We want to figure out the number of times 28658678 can be divided by 1.

On to step 1:
1 goes into 2 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 2 away from 2, we end up with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 1

Moving on to step 2:
1 can be fit into 8 8 times, resulting in a remainder of 0.
The next digit of our result is 8. 
Result so far: 28.0
If we subtract 8 from 8, we get 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 1

Moving on to step 3:
6 divided by 1 is 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 286.0
The remainder is 0 after subtracting 6 from 6.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

Step 4:
1 goes into 5 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 2865.0
If we take 5 away from 5, we end up with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

Step 5:
8 divided by 1 is 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 28658.0
If we take 8 away from 8, we end up with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 1

Advancing to step 6:
If we divide 6 by 1, we get 6 and a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 286586.0
Deduct 6 from 6 and we're left with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 1

Advancing to step 7:
1 can be fit into 7 7 times, resulting in a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 2865867.0
Subtract 7 from 7 to get 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 1

Moving on to step 8:
If we divide 8 by 1, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 28658678.0
If we take 8 away from 8, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
When dividing 0 by 1, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 28658678.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 28658678.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 28658678.0, and the remainder is 0.0.
