Let's divide 90039736 by 800
Our goal is to divide 90039736 by 800.

Moving on to step 1:
The number 800 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 800

On to step 2:
800 goes into 90 0 times with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Include the next digit (0) from the dividend after 90, then repeat: 900 / 800

Going ahead to step 3:
800 can be fit into 900 1 times, resulting in a remainder of 100.
The next digit of our result is 1. 
Result so far: 1.0
If we take 800 away from 900, we end up with 100.
Append the next digit (3) from the dividend to 100 and continue with: 1003 / 800

Advancing to step 4:
800 goes into 1003 1 times with a remainder of 203.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 800 from 1003 and we're left with 203.
Include the next digit (9) from the dividend after 203, then repeat: 2039 / 800

Step 5:
The number 800 fits into 2039 2 times, leaving a remainder of 439.
The next digit of our result is 2. 
Result so far: 112.0
Deduct 1600 from 2039 and we're left with 439.
Include the next digit (7) from the dividend after 439, then repeat: 4397 / 800

Moving on to step 6:
800 can be fit into 4397 5 times, resulting in a remainder of 397.
The number 5 becomes the next digit in our result. 
Result so far: 1125.0
The remainder is 397 after subtracting 4000 from 4397.
Append the next digit (3) from the dividend to 397 and continue with: 3973 / 800

Moving on to step 7:
800 goes into 3973 4 times with a remainder of 773.
The next digit of our result is 4. 
Result so far: 11254.0
If we take 3200 away from 3973, we end up with 773.
Take the next digit (6) from the dividend and append it to 773, then repeat: 7736 / 800

Let's proceed to step 8:
800 goes into 7736 9 times with a remainder of 536.
Write down 9 as next digit of the result. 
Result so far: 112549.0
Subtract 7200 from 7736 to get 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Let's proceed to step 9:
800 can be fit into 5360 6 times, resulting in a remainder of 560.
Record the quotient 6 as the next digit in the result. 
Result so far: 112549.6
Subtract 4800 from 5360 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 10:
5600 divided by 800 is 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 112549.67
If we take 5600 away from 5600, 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.

On to step 11:
The number 800 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 112549.67
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.

Step 12:
800 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 112549.67
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.

The final result is 112549.67 with a remainder of 0.0.
