We're dividing 18131498 by 689 
Let's see how many times 689 fits into 18131498.

Let's proceed to step 1:
When dividing 1 by 689, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 689

Step 2:
The number 689 fits into 18 0 times, leaving a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 689

Advancing to step 3:
If we divide 181 by 689, we get 0 and a remainder of 181.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 181, we end up with 181.
Take the next digit (3) from the dividend and append it to 181, then repeat: 1813 / 689

Going ahead to step 4:
The number 689 fits into 1813 2 times, leaving a remainder of 435.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 435 after subtracting 1378 from 1813.
Fetch the next digit (1) from the dividend, attach it to 435 and continue: 4351 / 689

On to step 5:
If we divide 4351 by 689, we get 6 and a remainder of 217.
Use 6 as the next digit of our solution. 
Result so far: 26.0
Deduct 4134 from 4351 and we're left with 217.
Grab the next digit (4) from the dividend, add it to 217, then carry on: 2174 / 689

Going ahead to step 6:
If we divide 2174 by 689, we get 3 and a remainder of 107.
Use 3 as the next digit of our solution. 
Result so far: 263.0
Subtract 2067 from 2174 to get 107.
Append the next digit (9) from the dividend to 107 and continue with: 1079 / 689

On to step 7:
When dividing 1079 by 689, we get 1 with a remainder of 390.
Use 1 as the next digit of our solution. 
Result so far: 2631.0
Deduct 689 from 1079 and we're left with 390.
Bring next digit (8) of the dividend behind the 390 and repeat the process: 3908 / 689

Moving on to step 8:
The number 689 fits into 3908 5 times, leaving a remainder of 463.
Put 5 as the next digit of the answer. 
Result so far: 26315.0
If we subtract 3445 from 3908, we get 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

On to step 9:
If we divide 4630 by 689, we get 6 and a remainder of 496.
Use 6 as the next digit of our solution. 
Result so far: 26315.6
Deduct 4134 from 4630 and we're left with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Advancing to step 10:
4960 divided by 689 is 7 with a remainder of 137.
Use 7 as the next digit of our solution. 
Result so far: 26315.67
Deduct 4823 from 4960 and we're left with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Advancing to step 11:
The number 689 fits into 1370 1 times, leaving a remainder of 681.
Write down 1 as next digit of the result. 
Result so far: 26315.671
The remainder is 681 after subtracting 689 from 1370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6810, and continue the process.

On to step 12:
If we divide 6810 by 689, we get 9 and a remainder of 609.
The next digit of our result is 9. 
Result so far: 26315.6719
Subtract 6201 from 6810 to get 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

Going ahead to step 13:
6090 divided by 689 is 8 with a remainder of 578.
Write down 8 as next digit of the result. 
Result so far: 26315.67198
Subtract 5512 from 6090 to get 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Advancing to step 14:
When dividing 5780 by 689, we get 8 with a remainder of 268.
The next digit of our result is 8. 
Result so far: 26315.671988
Subtracting 5512 from 5780 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

The final outcome is 26315.671988, with a leftover of 2.68e-05.
