Let's divide 78605816 by 689
We're looking to find how many times 689 goes into 78605816.

Advancing to step 1:
689 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 689

Step 2:
If we divide 78 by 689, we get 0 and a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Bring next digit (6) of the dividend behind the 78 and repeat the process: 786 / 689

Moving on to step 3:
689 can be fit into 786 1 times, resulting in a remainder of 97.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 97 after subtracting 689 from 786.
Take the next digit (0) from the dividend and append it to 97, then repeat: 970 / 689

Let's proceed to step 4:
If we divide 970 by 689, we get 1 and a remainder of 281.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 689 from 970, we get 281.
Grab the next digit (5) from the dividend, add it to 281, then carry on: 2815 / 689

Step 5:
689 can be fit into 2815 4 times, resulting in a remainder of 59.
Record the quotient 4 as the next digit in the result. 
Result so far: 114.0
If we take 2756 away from 2815, we end up with 59.
Bring next digit (8) of the dividend behind the 59 and repeat the process: 598 / 689

Let's proceed to step 6:
If we divide 598 by 689, we get 0 and a remainder of 598.
The next digit of our result is 0. 
Result so far: 1140.0
The remainder is 598 after subtracting 0 from 598.
Fetch the next digit (1) from the dividend, attach it to 598 and continue: 5981 / 689

Advancing to step 7:
If we divide 5981 by 689, we get 8 and a remainder of 469.
Write down 8 as next digit of the result. 
Result so far: 11408.0
Deduct 5512 from 5981 and we're left with 469.
Include the next digit (6) from the dividend after 469, then repeat: 4696 / 689

Step 8:
If we divide 4696 by 689, we get 6 and a remainder of 562.
Put 6 as the next digit of the answer. 
Result so far: 114086.0
Deduct 4134 from 4696 and we're left with 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Going ahead to step 9:
689 can be fit into 5620 8 times, resulting in a remainder of 108.
Write down 8 as next digit of the result. 
Result so far: 114086.8
If we take 5512 away from 5620, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 10:
The number 689 fits into 1080 1 times, leaving a remainder of 391.
Put 1 as the next digit of the answer. 
Result so far: 114086.81
The remainder is 391 after subtracting 689 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Let's proceed to step 11:
The number 689 fits into 3910 5 times, leaving a remainder of 465.
The number 5 becomes the next digit in our result. 
Result so far: 114086.815
Deduct 3445 from 3910 and we're left with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Step 12:
689 goes into 4650 6 times with a remainder of 516.
Put 6 as the next digit of the answer. 
Result so far: 114086.8156
If we subtract 4134 from 4650, we get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Going ahead to step 13:
5160 divided by 689 is 7 with a remainder of 337.
Write down 7 as next digit of the result. 
Result so far: 114086.81567
If we take 4823 away from 5160, we end up with 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Advancing to step 14:
689 can be fit into 3370 4 times, resulting in a remainder of 614.
Use 4 as the next digit of our solution. 
Result so far: 114086.815674
Deduct 2756 from 3370 and we're left with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

On to step 15:
If we divide 6140 by 689, we get 8 and a remainder of 628.
Write down 8 as next digit of the result. 
Result so far: 114086.8156748
If we take 5512 away from 6140, we end up with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

On to step 16:
The number 689 fits into 6280 9 times, leaving a remainder of 79.
Use 9 as the next digit of our solution. 
Result so far: 114086.81567489
If we subtract 6201 from 6280, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Our division results in 114086.81567489 with a remaining 7.9e-08.
