87164664 ÷ 809 
Our goal is to divide 87164664 by 809.

Going ahead to step 1:
809 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 809

Going ahead to step 2:
When dividing 87 by 809, we get 0 with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Bring next digit (1) of the dividend behind the 87 and repeat the process: 871 / 809

Let's proceed to step 3:
871 divided by 809 is 1 with a remainder of 62.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 62 after subtracting 809 from 871.
Append the next digit (6) from the dividend to 62 and continue with: 626 / 809

On to step 4:
When dividing 626 by 809, we get 0 with a remainder of 626.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 626 leaves us with 626.
Take the next digit (4) from the dividend and append it to 626, then repeat: 6264 / 809

Let's proceed to step 5:
809 goes into 6264 7 times with a remainder of 601.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
If we take 5663 away from 6264, we end up with 601.
Append the next digit (6) from the dividend to 601 and continue with: 6016 / 809

Step 6:
809 can be fit into 6016 7 times, resulting in a remainder of 353.
The number 7 becomes the next digit in our result. 
Result so far: 1077.0
The remainder is 353 after subtracting 5663 from 6016.
Append the next digit (6) from the dividend to 353 and continue with: 3536 / 809

Advancing to step 7:
The number 809 fits into 3536 4 times, leaving a remainder of 300.
Record the quotient 4 as the next digit in the result. 
Result so far: 10774.0
The remainder is 300 after subtracting 3236 from 3536.
Append the next digit (4) from the dividend to 300 and continue with: 3004 / 809

Advancing to step 8:
When dividing 3004 by 809, we get 3 with a remainder of 577.
Use 3 as the next digit of our solution. 
Result so far: 107743.0
The remainder is 577 after subtracting 2427 from 3004.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Step 9:
When dividing 5770 by 809, we get 7 with a remainder of 107.
Use 7 as the next digit of our solution. 
Result so far: 107743.7
Subtracting 5663 from 5770 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

On to step 10:
If we divide 1070 by 809, we get 1 and a remainder of 261.
The number 1 becomes the next digit in our result. 
Result so far: 107743.71
Subtracting 809 from 1070 leaves us with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Going ahead to step 11:
2610 divided by 809 is 3 with a remainder of 183.
The number 3 becomes the next digit in our result. 
Result so far: 107743.713
If we take 2427 away from 2610, we end up with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Advancing to step 12:
1830 divided by 809 is 2 with a remainder of 212.
Use 2 as the next digit of our solution. 
Result so far: 107743.7132
Subtract 1618 from 1830 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 13:
2120 divided by 809 is 2 with a remainder of 502.
Record the quotient 2 as the next digit in the result. 
Result so far: 107743.71322
If we take 1618 away from 2120, we end up with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

The quotient of the division is 107743.71322, and the remainder is 0.000502.
