80437915 ÷ 487 
Our goal is to divide 80437915 by 487.

Let's proceed to step 1:
487 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 487

Let's proceed to step 2:
80 divided by 487 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Include the next digit (4) from the dividend after 80, then repeat: 804 / 487

Moving on to step 3:
487 goes into 804 1 times with a remainder of 317.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 487 from 804 leaves us with 317.
Fetch the next digit (3) from the dividend, attach it to 317 and continue: 3173 / 487

Going ahead to step 4:
The number 487 fits into 3173 6 times, leaving a remainder of 251.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we subtract 2922 from 3173, we get 251.
Include the next digit (7) from the dividend after 251, then repeat: 2517 / 487

On to step 5:
2517 divided by 487 is 5 with a remainder of 82.
Record the quotient 5 as the next digit in the result. 
Result so far: 165.0
Subtracting 2435 from 2517 leaves us with 82.
Bring next digit (9) of the dividend behind the 82 and repeat the process: 829 / 487

On to step 6:
When dividing 829 by 487, we get 1 with a remainder of 342.
The number 1 becomes the next digit in our result. 
Result so far: 1651.0
If we subtract 487 from 829, we get 342.
Grab the next digit (1) from the dividend, add it to 342, then carry on: 3421 / 487

Advancing to step 7:
If we divide 3421 by 487, we get 7 and a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 16517.0
Subtracting 3409 from 3421 leaves us with 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 487

On to step 8:
487 can be fit into 125 0 times, resulting in a remainder of 125.
The next digit of our result is 0. 
Result so far: 165170.0
Subtract 0 from 125 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 9:
When dividing 1250 by 487, we get 2 with a remainder of 276.
Put 2 as the next digit of the answer. 
Result so far: 165170.2
Subtracting 974 from 1250 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 10:
487 goes into 2760 5 times with a remainder of 325.
The number 5 becomes the next digit in our result. 
Result so far: 165170.25
Subtract 2435 from 2760 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.

Let's proceed to step 11:
487 goes into 3250 6 times with a remainder of 328.
Put 6 as the next digit of the answer. 
Result so far: 165170.256
If we take 2922 away from 3250, we end up with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Let's proceed to step 12:
487 goes into 3280 6 times with a remainder of 358.
Record the quotient 6 as the next digit in the result. 
Result so far: 165170.2566
Deduct 2922 from 3280 and we're left with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

After the division, we end up with 165170.2566 and a remainder of 0.00358.
