We're dividing 66898930 by 809 
We want to figure out the number of times 66898930 can be divided by 809.

Advancing to step 1:
6 divided by 809 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 809

Going ahead to step 2:
The number 809 fits into 66 0 times, leaving a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Include the next digit (8) from the dividend after 66, then repeat: 668 / 809

Step 3:
The number 809 fits into 668 0 times, leaving a remainder of 668.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 668 to get 668.
Fetch the next digit (9) from the dividend, attach it to 668 and continue: 6689 / 809

Let's proceed to step 4:
If we divide 6689 by 809, we get 8 and a remainder of 217.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 6472 from 6689, we get 217.
Fetch the next digit (8) from the dividend, attach it to 217 and continue: 2178 / 809

Let's proceed to step 5:
If we divide 2178 by 809, we get 2 and a remainder of 560.
Use 2 as the next digit of our solution. 
Result so far: 82.0
Deduct 1618 from 2178 and we're left with 560.
Grab the next digit (9) from the dividend, add it to 560, then carry on: 5609 / 809

Step 6:
When dividing 5609 by 809, we get 6 with a remainder of 755.
Write down 6 as next digit of the result. 
Result so far: 826.0
Deduct 4854 from 5609 and we're left with 755.
Take the next digit (3) from the dividend and append it to 755, then repeat: 7553 / 809

Going ahead to step 7:
If we divide 7553 by 809, we get 9 and a remainder of 272.
The number 9 becomes the next digit in our result. 
Result so far: 8269.0
Subtract 7281 from 7553 to get 272.
Take the next digit (0) from the dividend and append it to 272, then repeat: 2720 / 809

Advancing to step 8:
When dividing 2720 by 809, we get 3 with a remainder of 293.
The number 3 becomes the next digit in our result. 
Result so far: 82693.0
Subtract 2427 from 2720 to get 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Moving on to step 9:
If we divide 2930 by 809, we get 3 and a remainder of 503.
Put 3 as the next digit of the answer. 
Result so far: 82693.3
If we subtract 2427 from 2930, we get 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Step 10:
809 goes into 5030 6 times with a remainder of 176.
The number 6 becomes the next digit in our result. 
Result so far: 82693.36
The remainder is 176 after subtracting 4854 from 5030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 11:
When dividing 1760 by 809, we get 2 with a remainder of 142.
Put 2 as the next digit of the answer. 
Result so far: 82693.362
If we subtract 1618 from 1760, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 12:
The number 809 fits into 1420 1 times, leaving a remainder of 611.
Use 1 as the next digit of our solution. 
Result so far: 82693.3621
Subtract 809 from 1420 to get 611.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6110, and continue the process.

Going ahead to step 13:
6110 divided by 809 is 7 with a remainder of 447.
Record the quotient 7 as the next digit in the result. 
Result so far: 82693.36217
If we take 5663 away from 6110, we end up with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Going ahead to step 14:
4470 divided by 809 is 5 with a remainder of 425.
Write down 5 as next digit of the result. 
Result so far: 82693.362175
If we take 4045 away from 4470, we end up with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

On to step 15:
If we divide 4250 by 809, we get 5 and a remainder of 205.
Write down 5 as next digit of the result. 
Result so far: 82693.3621755
Deduct 4045 from 4250 and we're left with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

After the division, we end up with 82693.3621755 and a remainder of 2.05e-06.
