43641593 divided by 800 
We want to figure out the number of times 43641593 can be divided by 800.

Going ahead to step 1:
800 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 800

Step 2:
When dividing 43 by 800, we get 0 with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Include the next digit (6) from the dividend after 43, then repeat: 436 / 800

On to step 3:
The number 800 fits into 436 0 times, leaving a remainder of 436.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 436, we get 436.
Include the next digit (4) from the dividend after 436, then repeat: 4364 / 800

Let's proceed to step 4:
If we divide 4364 by 800, we get 5 and a remainder of 364.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 4000 from 4364 leaves us with 364.
Take the next digit (1) from the dividend and append it to 364, then repeat: 3641 / 800

Going ahead to step 5:
When dividing 3641 by 800, we get 4 with a remainder of 441.
The number 4 becomes the next digit in our result. 
Result so far: 54.0
If we take 3200 away from 3641, we end up with 441.
Bring next digit (5) of the dividend behind the 441 and repeat the process: 4415 / 800

Going ahead to step 6:
When dividing 4415 by 800, we get 5 with a remainder of 415.
Record the quotient 5 as the next digit in the result. 
Result so far: 545.0
Subtract 4000 from 4415 to get 415.
Fetch the next digit (9) from the dividend, attach it to 415 and continue: 4159 / 800

Going ahead to step 7:
If we divide 4159 by 800, we get 5 and a remainder of 159.
Record the quotient 5 as the next digit in the result. 
Result so far: 5455.0
Subtract 4000 from 4159 to get 159.
Append the next digit (3) from the dividend to 159 and continue with: 1593 / 800

On to step 8:
800 goes into 1593 1 times with a remainder of 793.
The next digit of our result is 1. 
Result so far: 54551.0
The remainder is 793 after subtracting 800 from 1593.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7930, and continue the process.

Advancing to step 9:
When dividing 7930 by 800, we get 9 with a remainder of 730.
The number 9 becomes the next digit in our result. 
Result so far: 54551.9
Subtracting 7200 from 7930 leaves us with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Going ahead to step 10:
800 can be fit into 7300 9 times, resulting in a remainder of 100.
The next digit of our result is 9. 
Result so far: 54551.99
Subtract 7200 from 7300 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

In conclusion, the division gives 54551.99 with a balance of 0.1.
