13089860 ÷ 689 
Our goal is to divide 13089860 by 689.

Moving on to step 1:
If we divide 1 by 689, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 689

Advancing to step 2:
If we divide 13 by 689, we get 0 and a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 689

On to step 3:
If we divide 130 by 689, we get 0 and a remainder of 130.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 130 and we're left with 130.
Grab the next digit (8) from the dividend, add it to 130, then carry on: 1308 / 689

Going ahead to step 4:
1308 divided by 689 is 1 with a remainder of 619.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 689 from 1308 and we're left with 619.
Bring next digit (9) of the dividend behind the 619 and repeat the process: 6199 / 689

Going ahead to step 5:
When dividing 6199 by 689, we get 8 with a remainder of 687.
Write down 8 as next digit of the result. 
Result so far: 18.0
Deduct 5512 from 6199 and we're left with 687.
Bring next digit (8) of the dividend behind the 687 and repeat the process: 6878 / 689

Step 6:
689 goes into 6878 9 times with a remainder of 677.
Write down 9 as next digit of the result. 
Result so far: 189.0
Subtracting 6201 from 6878 leaves us with 677.
Fetch the next digit (6) from the dividend, attach it to 677 and continue: 6776 / 689

Going ahead to step 7:
When dividing 6776 by 689, we get 9 with a remainder of 575.
Write down 9 as next digit of the result. 
Result so far: 1899.0
The remainder is 575 after subtracting 6201 from 6776.
Append the next digit (0) from the dividend to 575 and continue with: 5750 / 689

On to step 8:
689 can be fit into 5750 8 times, resulting in a remainder of 238.
Put 8 as the next digit of the answer. 
Result so far: 18998.0
Subtracting 5512 from 5750 leaves us with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Let's proceed to step 9:
689 goes into 2380 3 times with a remainder of 313.
The next digit of our result is 3. 
Result so far: 18998.3
Subtract 2067 from 2380 to get 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Step 10:
If we divide 3130 by 689, we get 4 and a remainder of 374.
Record the quotient 4 as the next digit in the result. 
Result so far: 18998.34
Subtracting 2756 from 3130 leaves us with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Let's proceed to step 11:
If we divide 3740 by 689, we get 5 and a remainder of 295.
Use 5 as the next digit of our solution. 
Result so far: 18998.345
Deduct 3445 from 3740 and we're left with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Let's proceed to step 12:
If we divide 2950 by 689, we get 4 and a remainder of 194.
Write down 4 as next digit of the result. 
Result so far: 18998.3454
If we take 2756 away from 2950, we end up with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Step 13:
If we divide 1940 by 689, we get 2 and a remainder of 562.
The next digit of our result is 2. 
Result so far: 18998.34542
Subtract 1378 from 1940 to get 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Let's proceed to step 14:
689 goes into 5620 8 times with a remainder of 108.
Write down 8 as next digit of the result. 
Result so far: 18998.345428
Deduct 5512 from 5620 and we're left 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.

Let's proceed to step 15:
1080 divided by 689 is 1 with a remainder of 391.
The next digit of our result is 1. 
Result so far: 18998.3454281
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.

Advancing to step 16:
689 goes into 3910 5 times with a remainder of 465.
The number 5 becomes the next digit in our result. 
Result so far: 18998.34542815
If we take 3445 away from 3910, we end up 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.

After the division, we end up with 18998.34542815 and a remainder of 4.65e-07.
