903449 ÷ 86 
Let's see how many times 86 fits into 903449.

Moving on to step 1:
86 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 86

Advancing to step 2:
90 divided by 86 is 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 86 from 90 to get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 86

Going ahead to step 3:
The number 86 fits into 43 0 times, leaving a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 43 and we're left with 43.
Include the next digit (4) from the dividend after 43, then repeat: 434 / 86

Moving on to step 4:
When dividing 434 by 86, we get 5 with a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 105.0
Deduct 430 from 434 and we're left with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 86

Let's proceed to step 5:
If we divide 44 by 86, we get 0 and a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 1050.0
Deduct 0 from 44 and we're left with 44.
Fetch the next digit (9) from the dividend, attach it to 44 and continue: 449 / 86

Going ahead to step 6:
If we divide 449 by 86, we get 5 and a remainder of 19.
Write down 5 as next digit of the result. 
Result so far: 10505.0
The remainder is 19 after subtracting 430 from 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
86 can be fit into 190 2 times, resulting in a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 10505.2
The remainder is 18 after subtracting 172 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
180 divided by 86 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 10505.22
Subtracting 172 from 180 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 10505.22, and the remainder is 0.008.
