23954391 divided by 800 
We want to figure out the number of times 23954391 can be divided by 800.

Going ahead to step 1:
If we divide 2 by 800, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 800

Moving on to step 2:
23 divided by 800 is 0 with a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 800

Going ahead to step 3:
800 goes into 239 0 times with a remainder of 239.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 239 after subtracting 0 from 239.
Include the next digit (5) from the dividend after 239, then repeat: 2395 / 800

On to step 4:
When dividing 2395 by 800, we get 2 with a remainder of 795.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1600 from 2395 to get 795.
Grab the next digit (4) from the dividend, add it to 795, then carry on: 7954 / 800

Step 5:
When dividing 7954 by 800, we get 9 with a remainder of 754.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Subtracting 7200 from 7954 leaves us with 754.
Bring next digit (3) of the dividend behind the 754 and repeat the process: 7543 / 800

On to step 6:
When dividing 7543 by 800, we get 9 with a remainder of 343.
Write down 9 as next digit of the result. 
Result so far: 299.0
Deduct 7200 from 7543 and we're left with 343.
Fetch the next digit (9) from the dividend, attach it to 343 and continue: 3439 / 800

Advancing to step 7:
3439 divided by 800 is 4 with a remainder of 239.
The number 4 becomes the next digit in our result. 
Result so far: 2994.0
If we subtract 3200 from 3439, we get 239.
Include the next digit (1) from the dividend after 239, then repeat: 2391 / 800

Step 8:
2391 divided by 800 is 2 with a remainder of 791.
Use 2 as the next digit of our solution. 
Result so far: 29942.0
The remainder is 791 after subtracting 1600 from 2391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7910, and continue the process.

On to step 9:
If we divide 7910 by 800, we get 9 and a remainder of 710.
Use 9 as the next digit of our solution. 
Result so far: 29942.9
Deduct 7200 from 7910 and we're left with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Step 10:
800 goes into 7100 8 times with a remainder of 700.
Use 8 as the next digit of our solution. 
Result so far: 29942.98
Subtract 6400 from 7100 to get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Step 11:
When dividing 7000 by 800, we get 8 with a remainder of 600.
The next digit of our result is 8. 
Result so far: 29942.988
If we subtract 6400 from 7000, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final result is 29942.988 with a remainder of 0.06.
