28901795 ÷ 688 
We want to figure out the number of times 28901795 can be divided by 688.

Let's proceed to step 1:
If we divide 2 by 688, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 688

Let's proceed to step 2:
When dividing 28 by 688, we get 0 with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Include the next digit (9) from the dividend after 28, then repeat: 289 / 688

Going ahead to step 3:
When dividing 289 by 688, we get 0 with a remainder of 289.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 289 to get 289.
Take the next digit (0) from the dividend and append it to 289, then repeat: 2890 / 688

Going ahead to step 4:
The number 688 fits into 2890 4 times, leaving a remainder of 138.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 2752 from 2890, we get 138.
Append the next digit (1) from the dividend to 138 and continue with: 1381 / 688

On to step 5:
When dividing 1381 by 688, we get 2 with a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Deduct 1376 from 1381 and we're left with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 688

Moving on to step 6:
When dividing 57 by 688, we get 0 with a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 420.0
If we take 0 away from 57, we end up with 57.
Bring next digit (9) of the dividend behind the 57 and repeat the process: 579 / 688

Going ahead to step 7:
579 divided by 688 is 0 with a remainder of 579.
The number 0 becomes the next digit in our result. 
Result so far: 4200.0
If we subtract 0 from 579, we get 579.
Fetch the next digit (5) from the dividend, attach it to 579 and continue: 5795 / 688

Going ahead to step 8:
If we divide 5795 by 688, we get 8 and a remainder of 291.
Write down 8 as next digit of the result. 
Result so far: 42008.0
The remainder is 291 after subtracting 5504 from 5795.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Let's proceed to step 9:
The number 688 fits into 2910 4 times, leaving a remainder of 158.
Write down 4 as next digit of the result. 
Result so far: 42008.4
The remainder is 158 after subtracting 2752 from 2910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 10:
688 goes into 1580 2 times with a remainder of 204.
The number 2 becomes the next digit in our result. 
Result so far: 42008.42
If we subtract 1376 from 1580, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Going ahead to step 11:
When dividing 2040 by 688, we get 2 with a remainder of 664.
The number 2 becomes the next digit in our result. 
Result so far: 42008.422
Deduct 1376 from 2040 and we're left with 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

After the division, we end up with 42008.422 and a remainder of 0.0664.
