We divide 803487 by 8
We want to divide 803487 by 8.

Let's proceed to step 1:
When dividing 8 by 8, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 8 from 8 to get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 8

Let's proceed to step 2:
The number 8 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 0, we get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 8

Moving on to step 3:
The number 8 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 100.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 8

Moving on to step 4:
When dividing 34 by 8, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 1004.0
The remainder is 2 after subtracting 32 from 34.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 8

Moving on to step 5:
8 goes into 28 3 times with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 10043.0
Deduct 24 from 28 and we're left with 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 8

Going ahead to step 6:
8 goes into 47 5 times with a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 100435.0
If we subtract 40 from 47, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
8 goes into 70 8 times with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 100435.8
Subtracting 64 from 70 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
8 goes into 60 7 times with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 100435.87
If we take 56 away from 60, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
If we divide 40 by 8, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 100435.875
Subtracting 40 from 40 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.

Step 10:
When dividing 0 by 8, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 100435.875
If we take 0 away from 0, 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.

Let's proceed to step 11:
When dividing 0 by 8, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 100435.875
Deduct 0 from 0 and we're left 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.

The final result is 100435.875 with a remainder of 0.0.
