We divide 86639509 by 442
Let's see how many times 442 fits into 86639509.

Step 1:
8 divided by 442 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 442

Advancing to step 2:
When dividing 86 by 442, we get 0 with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Take the next digit (6) from the dividend and append it to 86, then repeat: 866 / 442

Moving on to step 3:
866 divided by 442 is 1 with a remainder of 424.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 442 away from 866, we end up with 424.
Append the next digit (3) from the dividend to 424 and continue with: 4243 / 442

Let's proceed to step 4:
442 can be fit into 4243 9 times, resulting in a remainder of 265.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we take 3978 away from 4243, we end up with 265.
Bring next digit (9) of the dividend behind the 265 and repeat the process: 2659 / 442

Moving on to step 5:
2659 divided by 442 is 6 with a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 196.0
Subtract 2652 from 2659 to get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 442

Moving on to step 6:
The number 442 fits into 75 0 times, leaving a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 1960.0
The remainder is 75 after subtracting 0 from 75.
Include the next digit (0) from the dividend after 75, then repeat: 750 / 442

Advancing to step 7:
If we divide 750 by 442, we get 1 and a remainder of 308.
Write down 1 as next digit of the result. 
Result so far: 19601.0
Subtracting 442 from 750 leaves us with 308.
Bring next digit (9) of the dividend behind the 308 and repeat the process: 3089 / 442

Let's proceed to step 8:
442 can be fit into 3089 6 times, resulting in a remainder of 437.
Put 6 as the next digit of the answer. 
Result so far: 196016.0
Deduct 2652 from 3089 and we're left with 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Let's proceed to step 9:
442 goes into 4370 9 times with a remainder of 392.
Use 9 as the next digit of our solution. 
Result so far: 196016.9
The remainder is 392 after subtracting 3978 from 4370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

On to step 10:
When dividing 3920 by 442, we get 8 with a remainder of 384.
Record the quotient 8 as the next digit in the result. 
Result so far: 196016.98
Subtracting 3536 from 3920 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Going ahead to step 11:
442 can be fit into 3840 8 times, resulting in a remainder of 304.
The number 8 becomes the next digit in our result. 
Result so far: 196016.988
If we take 3536 away from 3840, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Our division results in 196016.988 with a remaining 0.0304.
