70808536 divided by 689 
We want to figure out the number of times 70808536 can be divided by 689.

Step 1:
689 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 689

On to step 2:
If we divide 70 by 689, we get 0 and a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Bring next digit (8) of the dividend behind the 70 and repeat the process: 708 / 689

Moving on to step 3:
The number 689 fits into 708 1 times, leaving a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 689 away from 708, we end up with 19.
Fetch the next digit (0) from the dividend, attach it to 19 and continue: 190 / 689

Let's proceed to step 4:
When dividing 190 by 689, we get 0 with a remainder of 190.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 190 leaves us with 190.
Append the next digit (8) from the dividend to 190 and continue with: 1908 / 689

Advancing to step 5:
689 goes into 1908 2 times with a remainder of 530.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
Subtracting 1378 from 1908 leaves us with 530.
Bring next digit (5) of the dividend behind the 530 and repeat the process: 5305 / 689

Going ahead to step 6:
689 goes into 5305 7 times with a remainder of 482.
Write down 7 as next digit of the result. 
Result so far: 1027.0
Subtracting 4823 from 5305 leaves us with 482.
Include the next digit (3) from the dividend after 482, then repeat: 4823 / 689

Advancing to step 7:
The number 689 fits into 4823 7 times, leaving a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 10277.0
Deduct 4823 from 4823 and we're left with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 689

Moving on to step 8:
689 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 102770.0
If we subtract 0 from 6, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
If we divide 60 by 689, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 102770.0
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
If we divide 600 by 689, we get 0 and a remainder of 600.
Write down 0 as next digit of the result. 
Result so far: 102770.0
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final result is 102770.0 with a remainder of 0.6.
