78725374 ÷ 689 
We want to figure out the number of times 78725374 can be divided by 689.

Going ahead to step 1:
If we divide 7 by 689, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 689

Going ahead to step 2:
When dividing 78 by 689, we get 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Include the next digit (7) from the dividend after 78, then repeat: 787 / 689

Let's proceed to step 3:
If we divide 787 by 689, we get 1 and a remainder of 98.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 689 from 787 and we're left with 98.
Append the next digit (2) from the dividend to 98 and continue with: 982 / 689

Let's proceed to step 4:
982 divided by 689 is 1 with a remainder of 293.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 689 from 982 leaves us with 293.
Take the next digit (5) from the dividend and append it to 293, then repeat: 2935 / 689

Step 5:
If we divide 2935 by 689, we get 4 and a remainder of 179.
Use 4 as the next digit of our solution. 
Result so far: 114.0
Subtract 2756 from 2935 to get 179.
Append the next digit (3) from the dividend to 179 and continue with: 1793 / 689

Going ahead to step 6:
689 can be fit into 1793 2 times, resulting in a remainder of 415.
Put 2 as the next digit of the answer. 
Result so far: 1142.0
If we take 1378 away from 1793, we end up with 415.
Grab the next digit (7) from the dividend, add it to 415, then carry on: 4157 / 689

Going ahead to step 7:
The number 689 fits into 4157 6 times, leaving a remainder of 23.
The number 6 becomes the next digit in our result. 
Result so far: 11426.0
Deduct 4134 from 4157 and we're left with 23.
Bring next digit (4) of the dividend behind the 23 and repeat the process: 234 / 689

On to step 8:
If we divide 234 by 689, we get 0 and a remainder of 234.
The next digit of our result is 0. 
Result so far: 114260.0
If we take 0 away from 234, we end up with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Moving on to step 9:
The number 689 fits into 2340 3 times, leaving a remainder of 273.
Record the quotient 3 as the next digit in the result. 
Result so far: 114260.3
If we subtract 2067 from 2340, we get 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Let's proceed to step 10:
The number 689 fits into 2730 3 times, leaving a remainder of 663.
The number 3 becomes the next digit in our result. 
Result so far: 114260.33
If we take 2067 away from 2730, we end up with 663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

Our division results in 114260.33 with a remaining 0.663.
