Let's divide 803045 by 87
Let's see how many times 87 fits into 803045.

Moving on to step 1:
87 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 87

Step 2:
If we divide 80 by 87, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Take the next digit (3) from the dividend and append it to 80, then repeat: 803 / 87

Going ahead to step 3:
803 divided by 87 is 9 with a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 783 from 803, we get 20.
Append the next digit (0) from the dividend to 20 and continue with: 200 / 87

Let's proceed to step 4:
If we divide 200 by 87, we get 2 and a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 92.0
Subtracting 174 from 200 leaves us with 26.
Take the next digit (4) from the dividend and append it to 26, then repeat: 264 / 87

Step 5:
87 can be fit into 264 3 times, resulting in a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 923.0
If we subtract 261 from 264, we get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 87

Advancing to step 6:
87 can be fit into 35 0 times, resulting in a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 9230.0
Subtract 0 from 35 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 7:
87 goes into 350 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 9230.4
Deduct 348 from 350 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
87 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 9230.4
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
The number 87 fits into 200 2 times, leaving a remainder of 26.
The next digit of our result is 2. 
Result so far: 9230.402
Subtract 174 from 200 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 10:
87 goes into 260 2 times with a remainder of 86.
Put 2 as the next digit of the answer. 
Result so far: 9230.4022
Subtract 174 from 260 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

After the division, we end up with 9230.4022 and a remainder of 0.00086.
