We divide 84686331 by 509
We want to divide 84686331 by 509.

Advancing to step 1:
8 divided by 509 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 509

Going ahead to step 2:
When dividing 84 by 509, we get 0 with a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Grab the next digit (6) from the dividend, add it to 84, then carry on: 846 / 509

Step 3:
The number 509 fits into 846 1 times, leaving a remainder of 337.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 509 away from 846, we end up with 337.
Include the next digit (8) from the dividend after 337, then repeat: 3378 / 509

Going ahead to step 4:
3378 divided by 509 is 6 with a remainder of 324.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtract 3054 from 3378 to get 324.
Bring next digit (6) of the dividend behind the 324 and repeat the process: 3246 / 509

Moving on to step 5:
509 can be fit into 3246 6 times, resulting in a remainder of 192.
Write down 6 as next digit of the result. 
Result so far: 166.0
Subtracting 3054 from 3246 leaves us with 192.
Fetch the next digit (3) from the dividend, attach it to 192 and continue: 1923 / 509

Moving on to step 6:
1923 divided by 509 is 3 with a remainder of 396.
Write down 3 as next digit of the result. 
Result so far: 1663.0
If we subtract 1527 from 1923, we get 396.
Fetch the next digit (3) from the dividend, attach it to 396 and continue: 3963 / 509

Going ahead to step 7:
If we divide 3963 by 509, we get 7 and a remainder of 400.
Record the quotient 7 as the next digit in the result. 
Result so far: 16637.0
If we subtract 3563 from 3963, we get 400.
Include the next digit (1) from the dividend after 400, then repeat: 4001 / 509

Going ahead to step 8:
The number 509 fits into 4001 7 times, leaving a remainder of 438.
The number 7 becomes the next digit in our result. 
Result so far: 166377.0
If we subtract 3563 from 4001, we get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Going ahead to step 9:
509 goes into 4380 8 times with a remainder of 308.
Record the quotient 8 as the next digit in the result. 
Result so far: 166377.8
Subtract 4072 from 4380 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Advancing to step 10:
The number 509 fits into 3080 6 times, leaving a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 166377.86
Deduct 3054 from 3080 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 11:
If we divide 260 by 509, we get 0 and a remainder of 260.
The number 0 becomes the next digit in our result. 
Result so far: 166377.86
Subtract 0 from 260 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 12:
509 goes into 2600 5 times with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 166377.8605
Subtract 2545 from 2600 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 13:
The number 509 fits into 550 1 times, leaving a remainder of 41.
The next digit of our result is 1. 
Result so far: 166377.86051
If we subtract 509 from 550, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 14:
410 divided by 509 is 0 with a remainder of 410.
Use 0 as the next digit of our solution. 
Result so far: 166377.86051
The remainder is 410 after subtracting 0 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Moving on to step 15:
The number 509 fits into 4100 8 times, leaving a remainder of 28.
The next digit of our result is 8. 
Result so far: 166377.8605108
If we subtract 4072 from 4100, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 16:
509 goes into 280 0 times with a remainder of 280.
The next digit of our result is 0. 
Result so far: 166377.8605108
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.

Our division results in 166377.8605108 with a remaining 2.8e-07.
