We look at the division of 80206669 by 577 
We're looking to find how many times 577 goes into 80206669.

Step 1:
The number 577 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 577

Moving on to step 2:
The number 577 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Bring next digit (2) of the dividend behind the 80 and repeat the process: 802 / 577

Let's proceed to step 3:
802 divided by 577 is 1 with a remainder of 225.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 577 from 802 and we're left with 225.
Append the next digit (0) from the dividend to 225 and continue with: 2250 / 577

Advancing to step 4:
When dividing 2250 by 577, we get 3 with a remainder of 519.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 1731 from 2250 to get 519.
Bring next digit (6) of the dividend behind the 519 and repeat the process: 5196 / 577

Going ahead to step 5:
577 can be fit into 5196 9 times, resulting in a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 139.0
If we subtract 5193 from 5196, we get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 577

Let's proceed to step 6:
36 divided by 577 is 0 with a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 1390.0
If we subtract 0 from 36, we get 36.
Take the next digit (6) from the dividend and append it to 36, then repeat: 366 / 577

Step 7:
The number 577 fits into 366 0 times, leaving a remainder of 366.
Put 0 as the next digit of the answer. 
Result so far: 13900.0
The remainder is 366 after subtracting 0 from 366.
Fetch the next digit (9) from the dividend, attach it to 366 and continue: 3669 / 577

Let's proceed to step 8:
The number 577 fits into 3669 6 times, leaving a remainder of 207.
Record the quotient 6 as the next digit in the result. 
Result so far: 139006.0
Subtracting 3462 from 3669 leaves us with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Let's proceed to step 9:
If we divide 2070 by 577, we get 3 and a remainder of 339.
The next digit of our result is 3. 
Result so far: 139006.3
If we subtract 1731 from 2070, we get 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Moving on to step 10:
577 goes into 3390 5 times with a remainder of 505.
The number 5 becomes the next digit in our result. 
Result so far: 139006.35
Subtracting 2885 from 3390 leaves us with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Step 11:
577 goes into 5050 8 times with a remainder of 434.
The number 8 becomes the next digit in our result. 
Result so far: 139006.358
If we take 4616 away from 5050, we end up with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Step 12:
The number 577 fits into 4340 7 times, leaving a remainder of 301.
Record the quotient 7 as the next digit in the result. 
Result so far: 139006.3587
If we subtract 4039 from 4340, we get 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Going ahead to step 13:
When dividing 3010 by 577, we get 5 with a remainder of 125.
The next digit of our result is 5. 
Result so far: 139006.35875
Deduct 2885 from 3010 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 14:
577 goes into 1250 2 times with a remainder of 96.
Put 2 as the next digit of the answer. 
Result so far: 139006.358752
If we take 1154 away from 1250, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 15:
If we divide 960 by 577, we get 1 and a remainder of 383.
Put 1 as the next digit of the answer. 
Result so far: 139006.3587521
Deduct 577 from 960 and we're left with 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Going ahead to step 16:
The number 577 fits into 3830 6 times, leaving a remainder of 368.
The next digit of our result is 6. 
Result so far: 139006.35875216
The remainder is 368 after subtracting 3462 from 3830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

The final result is 139006.35875216 with a remainder of 3.68e-07.
