Let's divide 86669309 by 209
We want to figure out the number of times 86669309 can be divided by 209.

Step 1:
When dividing 8 by 209, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 209

Let's proceed to step 2:
When dividing 86 by 209, we get 0 with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Bring next digit (6) of the dividend behind the 86 and repeat the process: 866 / 209

Advancing to step 3:
209 can be fit into 866 4 times, resulting in a remainder of 30.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 836 from 866 to get 30.
Append the next digit (6) from the dividend to 30 and continue with: 306 / 209

Let's proceed to step 4:
If we divide 306 by 209, we get 1 and a remainder of 97.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
If we take 209 away from 306, we end up with 97.
Bring next digit (9) of the dividend behind the 97 and repeat the process: 979 / 209

Let's proceed to step 5:
209 can be fit into 979 4 times, resulting in a remainder of 143.
The number 4 becomes the next digit in our result. 
Result so far: 414.0
If we subtract 836 from 979, we get 143.
Bring next digit (3) of the dividend behind the 143 and repeat the process: 1433 / 209

Let's proceed to step 6:
If we divide 1433 by 209, we get 6 and a remainder of 179.
Put 6 as the next digit of the answer. 
Result so far: 4146.0
Deduct 1254 from 1433 and we're left with 179.
Include the next digit (0) from the dividend after 179, then repeat: 1790 / 209

Step 7:
The number 209 fits into 1790 8 times, leaving a remainder of 118.
The number 8 becomes the next digit in our result. 
Result so far: 41468.0
Subtracting 1672 from 1790 leaves us with 118.
Fetch the next digit (9) from the dividend, attach it to 118 and continue: 1189 / 209

Step 8:
209 can be fit into 1189 5 times, resulting in a remainder of 144.
Record the quotient 5 as the next digit in the result. 
Result so far: 414685.0
Subtracting 1045 from 1189 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 9:
1440 divided by 209 is 6 with a remainder of 186.
Record the quotient 6 as the next digit in the result. 
Result so far: 414685.6
The remainder is 186 after subtracting 1254 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Advancing to step 10:
209 can be fit into 1860 8 times, resulting in a remainder of 188.
The number 8 becomes the next digit in our result. 
Result so far: 414685.68
If we subtract 1672 from 1860, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

On to step 11:
When dividing 1880 by 209, we get 8 with a remainder of 208.
Write down 8 as next digit of the result. 
Result so far: 414685.688
Subtracting 1672 from 1880 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Our division results in 414685.688 with a remaining 0.0208.
