Let's divide 80999183 by 661
We're looking to find how many times 661 goes into 80999183.

Going ahead to step 1:
When dividing 8 by 661, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 661

Step 2:
661 goes into 80 0 times with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Append the next digit (9) from the dividend to 80 and continue with: 809 / 661

Moving on to step 3:
661 goes into 809 1 times with a remainder of 148.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 148 after subtracting 661 from 809.
Take the next digit (9) from the dividend and append it to 148, then repeat: 1489 / 661

On to step 4:
661 can be fit into 1489 2 times, resulting in a remainder of 167.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 1322 from 1489 and we're left with 167.
Append the next digit (9) from the dividend to 167 and continue with: 1679 / 661

Moving on to step 5:
661 goes into 1679 2 times with a remainder of 357.
The next digit of our result is 2. 
Result so far: 122.0
If we subtract 1322 from 1679, we get 357.
Append the next digit (1) from the dividend to 357 and continue with: 3571 / 661

Advancing to step 6:
661 can be fit into 3571 5 times, resulting in a remainder of 266.
Use 5 as the next digit of our solution. 
Result so far: 1225.0
If we subtract 3305 from 3571, we get 266.
Take the next digit (8) from the dividend and append it to 266, then repeat: 2668 / 661

Advancing to step 7:
2668 divided by 661 is 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 12254.0
If we subtract 2644 from 2668, we get 24.
Take the next digit (3) from the dividend and append it to 24, then repeat: 243 / 661

Step 8:
If we divide 243 by 661, we get 0 and a remainder of 243.
The next digit of our result is 0. 
Result so far: 122540.0
The remainder is 243 after subtracting 0 from 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Let's proceed to step 9:
When dividing 2430 by 661, we get 3 with a remainder of 447.
The next digit of our result is 3. 
Result so far: 122540.3
Deduct 1983 from 2430 and we're left 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.

Advancing to step 10:
661 can be fit into 4470 6 times, resulting in a remainder of 504.
The next digit of our result is 6. 
Result so far: 122540.36
If we subtract 3966 from 4470, we get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Advancing to step 11:
The number 661 fits into 5040 7 times, leaving a remainder of 413.
The number 7 becomes the next digit in our result. 
Result so far: 122540.367
If we subtract 4627 from 5040, we get 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Going ahead to step 12:
661 can be fit into 4130 6 times, resulting in a remainder of 164.
The next digit of our result is 6. 
Result so far: 122540.3676
Subtracting 3966 from 4130 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 13:
661 goes into 1640 2 times with a remainder of 318.
Put 2 as the next digit of the answer. 
Result so far: 122540.36762
Subtract 1322 from 1640 to get 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Moving on to step 14:
The number 661 fits into 3180 4 times, leaving a remainder of 536.
Put 4 as the next digit of the answer. 
Result so far: 122540.367624
Deduct 2644 from 3180 and we're left with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Advancing to step 15:
The number 661 fits into 5360 8 times, leaving a remainder of 72.
The next digit of our result is 8. 
Result so far: 122540.3676248
Subtract 5288 from 5360 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 16:
When dividing 720 by 661, we get 1 with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 122540.36762481
If we take 661 away from 720, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

After the division, we end up with 122540.36762481 and a remainder of 5.9e-08.
