Let's divide 1272989 by 815
We want to divide 1272989 by 815.

Going ahead to step 1:
1 divided by 815 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 815

Going ahead to step 2:
If we divide 12 by 815, we get 0 and a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 815

On to step 3:
815 can be fit into 127 0 times, resulting in a remainder of 127.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 127, we end up with 127.
Take the next digit (2) from the dividend and append it to 127, then repeat: 1272 / 815

Moving on to step 4:
1272 divided by 815 is 1 with a remainder of 457.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 457 after subtracting 815 from 1272.
Fetch the next digit (9) from the dividend, attach it to 457 and continue: 4579 / 815

Let's proceed to step 5:
When dividing 4579 by 815, we get 5 with a remainder of 504.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 4075 away from 4579, we end up with 504.
Fetch the next digit (8) from the dividend, attach it to 504 and continue: 5048 / 815

Advancing to step 6:
815 goes into 5048 6 times with a remainder of 158.
The next digit of our result is 6. 
Result so far: 156.0
Subtracting 4890 from 5048 leaves us with 158.
Grab the next digit (9) from the dividend, add it to 158, then carry on: 1589 / 815

Moving on to step 7:
If we divide 1589 by 815, we get 1 and a remainder of 774.
The number 1 becomes the next digit in our result. 
Result so far: 1561.0
If we subtract 815 from 1589, we get 774.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7740, and continue the process.

On to step 8:
815 goes into 7740 9 times with a remainder of 405.
Record the quotient 9 as the next digit in the result. 
Result so far: 1561.9
Subtracting 7335 from 7740 leaves us with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Step 9:
4050 divided by 815 is 4 with a remainder of 790.
Use 4 as the next digit of our solution. 
Result so far: 1561.94
Subtracting 3260 from 4050 leaves us with 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Going ahead to step 10:
815 can be fit into 7900 9 times, resulting in a remainder of 565.
The next digit of our result is 9. 
Result so far: 1561.949
If we take 7335 away from 7900, we end up with 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Going ahead to step 11:
5650 divided by 815 is 6 with a remainder of 760.
Write down 6 as next digit of the result. 
Result so far: 1561.9496
If we subtract 4890 from 5650, we get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Moving on to step 12:
When dividing 7600 by 815, we get 9 with a remainder of 265.
Record the quotient 9 as the next digit in the result. 
Result so far: 1561.94969
Subtracting 7335 from 7600 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Advancing to step 13:
When dividing 2650 by 815, we get 3 with a remainder of 205.
Write down 3 as next digit of the result. 
Result so far: 1561.949693
If we take 2445 away from 2650, we end up with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Step 14:
The number 815 fits into 2050 2 times, leaving a remainder of 420.
Use 2 as the next digit of our solution. 
Result so far: 1561.9496932
Subtract 1630 from 2050 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 15:
When dividing 4200 by 815, we get 5 with a remainder of 125.
The next digit of our result is 5. 
Result so far: 1561.94969325
Subtracting 4075 from 4200 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

In conclusion, the division gives 1561.94969325 with a balance of 1.25e-07.
