We look at the division of 86459009 by 553 
We're looking to find how many times 553 goes into 86459009.

Going ahead to step 1:
The number 553 fits into 8 0 times, leaving 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.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 553

Let's proceed to step 2:
86 divided by 553 is 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Bring next digit (4) of the dividend behind the 86 and repeat the process: 864 / 553

Going ahead to step 3:
864 divided by 553 is 1 with a remainder of 311.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 553 away from 864, we end up with 311.
Include the next digit (5) from the dividend after 311, then repeat: 3115 / 553

Going ahead to step 4:
553 goes into 3115 5 times with a remainder of 350.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 2765 from 3115 leaves us with 350.
Take the next digit (9) from the dividend and append it to 350, then repeat: 3509 / 553

Advancing to step 5:
553 can be fit into 3509 6 times, resulting in a remainder of 191.
The next digit of our result is 6. 
Result so far: 156.0
Subtracting 3318 from 3509 leaves us with 191.
Grab the next digit (0) from the dividend, add it to 191, then carry on: 1910 / 553

Moving on to step 6:
The number 553 fits into 1910 3 times, leaving a remainder of 251.
The next digit of our result is 3. 
Result so far: 1563.0
Deduct 1659 from 1910 and we're left with 251.
Fetch the next digit (0) from the dividend, attach it to 251 and continue: 2510 / 553

Advancing to step 7:
The number 553 fits into 2510 4 times, leaving a remainder of 298.
Use 4 as the next digit of our solution. 
Result so far: 15634.0
If we subtract 2212 from 2510, we get 298.
Append the next digit (9) from the dividend to 298 and continue with: 2989 / 553

Let's proceed to step 8:
553 can be fit into 2989 5 times, resulting in a remainder of 224.
The number 5 becomes the next digit in our result. 
Result so far: 156345.0
Deduct 2765 from 2989 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 9:
When dividing 2240 by 553, we get 4 with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 156345.4
Subtracting 2212 from 2240 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
The number 553 fits into 280 0 times, leaving a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 156345.4
The remainder is 280 after subtracting 0 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 11:
If we divide 2800 by 553, we get 5 and a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 156345.405
The remainder is 35 after subtracting 2765 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 12:
When dividing 350 by 553, we get 0 with a remainder of 350.
The number 0 becomes the next digit in our result. 
Result so far: 156345.405
Subtracting 0 from 350 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 13:
553 goes into 3500 6 times with a remainder of 182.
Write down 6 as next digit of the result. 
Result so far: 156345.40506
Subtracting 3318 from 3500 leaves us with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Step 14:
1820 divided by 553 is 3 with a remainder of 161.
The next digit of our result is 3. 
Result so far: 156345.405063
If we subtract 1659 from 1820, we get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Moving on to step 15:
The number 553 fits into 1610 2 times, leaving a remainder of 504.
The number 2 becomes the next digit in our result. 
Result so far: 156345.4050632
If we take 1106 away from 1610, we end up with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Advancing to step 16:
When dividing 5040 by 553, we get 9 with a remainder of 63.
The number 9 becomes the next digit in our result. 
Result so far: 156345.40506329
Subtracting 4977 from 5040 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

The final result is 156345.40506329 with a remainder of 6.3e-08.
