Let's divide 12972691 by 587
We want to divide 12972691 by 587.

On to step 1:
If we divide 1 by 587, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 587

Going ahead to step 2:
When dividing 12 by 587, we get 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 587

Step 3:
129 divided by 587 is 0 with a remainder of 129.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 129, we get 129.
Take the next digit (7) from the dividend and append it to 129, then repeat: 1297 / 587

Let's proceed to step 4:
When dividing 1297 by 587, we get 2 with a remainder of 123.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 123 after subtracting 1174 from 1297.
Include the next digit (2) from the dividend after 123, then repeat: 1232 / 587

Advancing to step 5:
1232 divided by 587 is 2 with a remainder of 58.
The next digit of our result is 2. 
Result so far: 22.0
Subtracting 1174 from 1232 leaves us with 58.
Take the next digit (6) from the dividend and append it to 58, then repeat: 586 / 587

Going ahead to step 6:
587 goes into 586 0 times with a remainder of 586.
Record the quotient 0 as the next digit in the result. 
Result so far: 220.0
Subtracting 0 from 586 leaves us with 586.
Grab the next digit (9) from the dividend, add it to 586, then carry on: 5869 / 587

Moving on to step 7:
587 can be fit into 5869 9 times, resulting in a remainder of 586.
The next digit of our result is 9. 
Result so far: 2209.0
Subtracting 5283 from 5869 leaves us with 586.
Bring next digit (1) of the dividend behind the 586 and repeat the process: 5861 / 587

Step 8:
5861 divided by 587 is 9 with a remainder of 578.
Put 9 as the next digit of the answer. 
Result so far: 22099.0
If we subtract 5283 from 5861, we 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.

Step 9:
5780 divided by 587 is 9 with a remainder of 497.
Use 9 as the next digit of our solution. 
Result so far: 22099.9
If we take 5283 away from 5780, we end up with 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

Going ahead to step 10:
4970 divided by 587 is 8 with a remainder of 274.
The next digit of our result is 8. 
Result so far: 22099.98
Subtracting 4696 from 4970 leaves us with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 11:
587 can be fit into 2740 4 times, resulting in a remainder of 392.
The next digit of our result is 4. 
Result so far: 22099.984
The remainder is 392 after subtracting 2348 from 2740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Let's proceed to step 12:
The number 587 fits into 3920 6 times, leaving a remainder of 398.
Record the quotient 6 as the next digit in the result. 
Result so far: 22099.9846
Deduct 3522 from 3920 and we're left with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Going ahead to step 13:
3980 divided by 587 is 6 with a remainder of 458.
Record the quotient 6 as the next digit in the result. 
Result so far: 22099.98466
Subtract 3522 from 3980 to get 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

The final outcome is 22099.98466, with a leftover of 0.000458.
