80466390 divided by 561 
We're looking to find how many times 561 goes into 80466390.

Moving on to step 1:
8 divided by 561 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 561

Going ahead to step 2:
561 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Fetch the next digit (4) from the dividend, attach it to 80 and continue: 804 / 561

Advancing to step 3:
804 divided by 561 is 1 with a remainder of 243.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 243 after subtracting 561 from 804.
Fetch the next digit (6) from the dividend, attach it to 243 and continue: 2436 / 561

Moving on to step 4:
The number 561 fits into 2436 4 times, leaving a remainder of 192.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtract 2244 from 2436 to get 192.
Bring next digit (6) of the dividend behind the 192 and repeat the process: 1926 / 561

Advancing to step 5:
561 goes into 1926 3 times with a remainder of 243.
Write down 3 as next digit of the result. 
Result so far: 143.0
The remainder is 243 after subtracting 1683 from 1926.
Bring next digit (3) of the dividend behind the 243 and repeat the process: 2433 / 561

Going ahead to step 6:
If we divide 2433 by 561, we get 4 and a remainder of 189.
Use 4 as the next digit of our solution. 
Result so far: 1434.0
If we take 2244 away from 2433, we end up with 189.
Take the next digit (9) from the dividend and append it to 189, then repeat: 1899 / 561

Advancing to step 7:
561 can be fit into 1899 3 times, resulting in a remainder of 216.
Use 3 as the next digit of our solution. 
Result so far: 14343.0
If we take 1683 away from 1899, we end up with 216.
Fetch the next digit (0) from the dividend, attach it to 216 and continue: 2160 / 561

Let's proceed to step 8:
When dividing 2160 by 561, we get 3 with a remainder of 477.
The number 3 becomes the next digit in our result. 
Result so far: 143433.0
If we take 1683 away from 2160, we end up with 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

On to step 9:
The number 561 fits into 4770 8 times, leaving a remainder of 282.
Record the quotient 8 as the next digit in the result. 
Result so far: 143433.8
The remainder is 282 after subtracting 4488 from 4770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Step 10:
561 can be fit into 2820 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 143433.85
If we subtract 2805 from 2820, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 11:
561 can be fit into 150 0 times, resulting in a remainder of 150.
The next digit of our result is 0. 
Result so far: 143433.85
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 12:
1500 divided by 561 is 2 with a remainder of 378.
Write down 2 as next digit of the result. 
Result so far: 143433.8502
Subtract 1122 from 1500 to get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Going ahead to step 13:
561 can be fit into 3780 6 times, resulting in a remainder of 414.
Write down 6 as next digit of the result. 
Result so far: 143433.85026
Deduct 3366 from 3780 and we're left with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

On to step 14:
561 goes into 4140 7 times with a remainder of 213.
Use 7 as the next digit of our solution. 
Result so far: 143433.850267
If we take 3927 away from 4140, we end up with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Advancing to step 15:
The number 561 fits into 2130 3 times, leaving a remainder of 447.
Write down 3 as next digit of the result. 
Result so far: 143433.8502673
Subtracting 1683 from 2130 leaves us 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.

On to step 16:
When dividing 4470 by 561, we get 7 with a remainder of 543.
Put 7 as the next digit of the answer. 
Result so far: 143433.85026737
If we subtract 3927 from 4470, we get 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

After the division, we end up with 143433.85026737 and a remainder of 5.43e-07.
