80531505 ÷ 673 
We want to divide 80531505 by 673.

Step 1:
673 can be fit into 8 0 times, resulting in 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.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 673

Going ahead to step 2:
When dividing 80 by 673, we get 0 with 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.
Append the next digit (5) from the dividend to 80 and continue with: 805 / 673

Step 3:
805 divided by 673 is 1 with a remainder of 132.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 673 from 805 to get 132.
Include the next digit (3) from the dividend after 132, then repeat: 1323 / 673

On to step 4:
The number 673 fits into 1323 1 times, leaving a remainder of 650.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 673 from 1323, we get 650.
Grab the next digit (1) from the dividend, add it to 650, then carry on: 6501 / 673

On to step 5:
673 can be fit into 6501 9 times, resulting in a remainder of 444.
Write down 9 as next digit of the result. 
Result so far: 119.0
Subtract 6057 from 6501 to get 444.
Take the next digit (5) from the dividend and append it to 444, then repeat: 4445 / 673

Step 6:
673 goes into 4445 6 times with a remainder of 407.
The next digit of our result is 6. 
Result so far: 1196.0
If we subtract 4038 from 4445, we get 407.
Take the next digit (0) from the dividend and append it to 407, then repeat: 4070 / 673

Step 7:
4070 divided by 673 is 6 with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 11966.0
If we take 4038 away from 4070, we end up with 32.
Bring next digit (5) of the dividend behind the 32 and repeat the process: 325 / 673

Step 8:
673 can be fit into 325 0 times, resulting in a remainder of 325.
Put 0 as the next digit of the answer. 
Result so far: 119660.0
Subtract 0 from 325 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Advancing to step 9:
3250 divided by 673 is 4 with a remainder of 558.
Use 4 as the next digit of our solution. 
Result so far: 119660.4
If we subtract 2692 from 3250, we get 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Moving on to step 10:
If we divide 5580 by 673, we get 8 and a remainder of 196.
Use 8 as the next digit of our solution. 
Result so far: 119660.48
The remainder is 196 after subtracting 5384 from 5580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Let's proceed to step 11:
1960 divided by 673 is 2 with a remainder of 614.
Write down 2 as next digit of the result. 
Result so far: 119660.482
If we take 1346 away from 1960, we end up with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Step 12:
The number 673 fits into 6140 9 times, leaving a remainder of 83.
Record the quotient 9 as the next digit in the result. 
Result so far: 119660.4829
Subtracting 6057 from 6140 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 13:
830 divided by 673 is 1 with a remainder of 157.
Write down 1 as next digit of the result. 
Result so far: 119660.48291
If we subtract 673 from 830, we get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Step 14:
1570 divided by 673 is 2 with a remainder of 224.
Use 2 as the next digit of our solution. 
Result so far: 119660.482912
The remainder is 224 after subtracting 1346 from 1570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 15:
673 goes into 2240 3 times with a remainder of 221.
The next digit of our result is 3. 
Result so far: 119660.4829123
Deduct 2019 from 2240 and we're left with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Moving on to step 16:
The number 673 fits into 2210 3 times, leaving a remainder of 191.
Put 3 as the next digit of the answer. 
Result so far: 119660.48291233
Deduct 2019 from 2210 and we're left with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

The final result is 119660.48291233 with a remainder of 1.91e-07.
