66712535 ÷ 809 
Let's see how many times 809 fits into 66712535.

Let's proceed to step 1:
809 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 809

Step 2:
809 goes into 66 0 times with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Take the next digit (7) from the dividend and append it to 66, then repeat: 667 / 809

Going ahead to step 3:
809 can be fit into 667 0 times, resulting in a remainder of 667.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 667 to get 667.
Bring next digit (1) of the dividend behind the 667 and repeat the process: 6671 / 809

On to step 4:
809 can be fit into 6671 8 times, resulting in a remainder of 199.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 6472 from 6671 to get 199.
Take the next digit (2) from the dividend and append it to 199, then repeat: 1992 / 809

Let's proceed to step 5:
The number 809 fits into 1992 2 times, leaving a remainder of 374.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
The remainder is 374 after subtracting 1618 from 1992.
Grab the next digit (5) from the dividend, add it to 374, then carry on: 3745 / 809

Step 6:
809 goes into 3745 4 times with a remainder of 509.
Write down 4 as next digit of the result. 
Result so far: 824.0
The remainder is 509 after subtracting 3236 from 3745.
Fetch the next digit (3) from the dividend, attach it to 509 and continue: 5093 / 809

Let's proceed to step 7:
809 goes into 5093 6 times with a remainder of 239.
Record the quotient 6 as the next digit in the result. 
Result so far: 8246.0
The remainder is 239 after subtracting 4854 from 5093.
Grab the next digit (5) from the dividend, add it to 239, then carry on: 2395 / 809

Let's proceed to step 8:
809 goes into 2395 2 times with a remainder of 777.
Write down 2 as next digit of the result. 
Result so far: 82462.0
The remainder is 777 after subtracting 1618 from 2395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7770, and continue the process.

Step 9:
When dividing 7770 by 809, we get 9 with a remainder of 489.
Write down 9 as next digit of the result. 
Result so far: 82462.9
Deduct 7281 from 7770 and we're left with 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Advancing to step 10:
809 can be fit into 4890 6 times, resulting in a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 82462.96
Deduct 4854 from 4890 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
360 divided by 809 is 0 with a remainder of 360.
Use 0 as the next digit of our solution. 
Result so far: 82462.96
The remainder is 360 after subtracting 0 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 12:
809 goes into 3600 4 times with a remainder of 364.
Put 4 as the next digit of the answer. 
Result so far: 82462.9604
If we take 3236 away from 3600, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Moving on to step 13:
If we divide 3640 by 809, we get 4 and a remainder of 404.
Write down 4 as next digit of the result. 
Result so far: 82462.96044
If we take 3236 away from 3640, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

In conclusion, the division gives 82462.96044 with a balance of 0.000404.
