13246215 ÷ 800 
Our goal is to divide 13246215 by 800.

Step 1:
If we divide 1 by 800, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 800

Let's proceed to step 2:
800 goes into 13 0 times with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 800

Moving on to step 3:
132 divided by 800 is 0 with a remainder of 132.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 132 and we're left with 132.
Include the next digit (4) from the dividend after 132, then repeat: 1324 / 800

Let's proceed to step 4:
If we divide 1324 by 800, we get 1 and a remainder of 524.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 524 after subtracting 800 from 1324.
Take the next digit (6) from the dividend and append it to 524, then repeat: 5246 / 800

Advancing to step 5:
The number 800 fits into 5246 6 times, leaving a remainder of 446.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtracting 4800 from 5246 leaves us with 446.
Fetch the next digit (2) from the dividend, attach it to 446 and continue: 4462 / 800

On to step 6:
800 can be fit into 4462 5 times, resulting in a remainder of 462.
Put 5 as the next digit of the answer. 
Result so far: 165.0
If we take 4000 away from 4462, we end up with 462.
Append the next digit (1) from the dividend to 462 and continue with: 4621 / 800

Going ahead to step 7:
4621 divided by 800 is 5 with a remainder of 621.
Write down 5 as next digit of the result. 
Result so far: 1655.0
If we subtract 4000 from 4621, we get 621.
Append the next digit (5) from the dividend to 621 and continue with: 6215 / 800

Moving on to step 8:
800 goes into 6215 7 times with a remainder of 615.
The number 7 becomes the next digit in our result. 
Result so far: 16557.0
Subtracting 5600 from 6215 leaves us with 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

On to step 9:
6150 divided by 800 is 7 with a remainder of 550.
The next digit of our result is 7. 
Result so far: 16557.7
If we take 5600 away from 6150, we end up with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Step 10:
The number 800 fits into 5500 6 times, leaving a remainder of 700.
The next digit of our result is 6. 
Result so far: 16557.76
Subtracting 4800 from 5500 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Moving on to step 11:
If we divide 7000 by 800, we get 8 and a remainder of 600.
Write down 8 as next digit of the result. 
Result so far: 16557.768
Deduct 6400 from 7000 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 12:
6000 divided by 800 is 7 with a remainder of 400.
Record the quotient 7 as the next digit in the result. 
Result so far: 16557.7687
Subtract 5600 from 6000 to 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.

Advancing to step 13:
800 can be fit into 4000 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 16557.76875
If we subtract 4000 from 4000, we get 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 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 16557.76875
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

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: 16557.76875
Subtracting 0 from 0 leaves us 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.

Our division results in 16557.76875 with a remaining 0.0.
