We look at the division of 12710229 by 800 
Our goal is to divide 12710229 by 800.

Moving on to step 1:
If we divide 1 by 800, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 800

Moving on to step 2:
If we divide 12 by 800, we get 0 and a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Append the next digit (7) from the dividend to 12 and continue with: 127 / 800

Let's proceed to step 3:
800 goes into 127 0 times with a remainder of 127.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 127 to get 127.
Bring next digit (1) of the dividend behind the 127 and repeat the process: 1271 / 800

Advancing to step 4:
The number 800 fits into 1271 1 times, leaving a remainder of 471.
The next digit of our result is 1. 
Result so far: 1.0
If we take 800 away from 1271, we end up with 471.
Fetch the next digit (0) from the dividend, attach it to 471 and continue: 4710 / 800

Going ahead to step 5:
4710 divided by 800 is 5 with a remainder of 710.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 710 after subtracting 4000 from 4710.
Bring next digit (2) of the dividend behind the 710 and repeat the process: 7102 / 800

Advancing to step 6:
If we divide 7102 by 800, we get 8 and a remainder of 702.
Record the quotient 8 as the next digit in the result. 
Result so far: 158.0
If we take 6400 away from 7102, we end up with 702.
Take the next digit (2) from the dividend and append it to 702, then repeat: 7022 / 800

Moving on to step 7:
800 goes into 7022 8 times with a remainder of 622.
Write down 8 as next digit of the result. 
Result so far: 1588.0
Subtract 6400 from 7022 to get 622.
Fetch the next digit (9) from the dividend, attach it to 622 and continue: 6229 / 800

Moving on to step 8:
If we divide 6229 by 800, we get 7 and a remainder of 629.
Put 7 as the next digit of the answer. 
Result so far: 15887.0
The remainder is 629 after subtracting 5600 from 6229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6290, and continue the process.

Moving on to step 9:
800 can be fit into 6290 7 times, resulting in a remainder of 690.
The number 7 becomes the next digit in our result. 
Result so far: 15887.7
The remainder is 690 after subtracting 5600 from 6290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Advancing to step 10:
800 goes into 6900 8 times with a remainder of 500.
Record the quotient 8 as the next digit in the result. 
Result so far: 15887.78
The remainder is 500 after subtracting 6400 from 6900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 11:
800 can be fit into 5000 6 times, resulting in a remainder of 200.
Use 6 as the next digit of our solution. 
Result so far: 15887.786
If we subtract 4800 from 5000, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 12:
800 goes into 2000 2 times with a remainder of 400.
Write down 2 as next digit of the result. 
Result so far: 15887.7862
If we subtract 1600 from 2000, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 13:
4000 divided by 800 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 15887.78625
If we take 4000 away from 4000, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 14:
800 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15887.78625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 15:
800 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15887.78625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 15887.78625, with a leftover of 0.0.
