77971045 ÷ 487 
We want to divide 77971045 by 487.

Advancing to step 1:
487 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 487

Step 2:
If we divide 77 by 487, we get 0 and a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Append the next digit (9) from the dividend to 77 and continue with: 779 / 487

Step 3:
When dividing 779 by 487, we get 1 with a remainder of 292.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 487 from 779 leaves us with 292.
Bring next digit (7) of the dividend behind the 292 and repeat the process: 2927 / 487

Step 4:
If we divide 2927 by 487, we get 6 and a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 2922 from 2927 and we're left with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 487

On to step 5:
487 goes into 51 0 times with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 160.0
Subtracting 0 from 51 leaves us with 51.
Fetch the next digit (0) from the dividend, attach it to 51 and continue: 510 / 487

Moving on to step 6:
When dividing 510 by 487, we get 1 with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 1601.0
The remainder is 23 after subtracting 487 from 510.
Grab the next digit (4) from the dividend, add it to 23, then carry on: 234 / 487

Let's proceed to step 7:
When dividing 234 by 487, we get 0 with a remainder of 234.
Use 0 as the next digit of our solution. 
Result so far: 16010.0
The remainder is 234 after subtracting 0 from 234.
Append the next digit (5) from the dividend to 234 and continue with: 2345 / 487

On to step 8:
2345 divided by 487 is 4 with a remainder of 397.
Put 4 as the next digit of the answer. 
Result so far: 160104.0
If we subtract 1948 from 2345, we get 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

On to step 9:
487 goes into 3970 8 times with a remainder of 74.
Put 8 as the next digit of the answer. 
Result so far: 160104.8
Deduct 3896 from 3970 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 10:
740 divided by 487 is 1 with a remainder of 253.
The next digit of our result is 1. 
Result so far: 160104.81
Deduct 487 from 740 and we're left with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

On to step 11:
The number 487 fits into 2530 5 times, leaving a remainder of 95.
The number 5 becomes the next digit in our result. 
Result so far: 160104.815
If we take 2435 away from 2530, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 12:
487 goes into 950 1 times with a remainder of 463.
Use 1 as the next digit of our solution. 
Result so far: 160104.8151
The remainder is 463 after subtracting 487 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

On to step 13:
If we divide 4630 by 487, we get 9 and a remainder of 247.
Record the quotient 9 as the next digit in the result. 
Result so far: 160104.81519
Subtract 4383 from 4630 to get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

On to step 14:
When dividing 2470 by 487, we get 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 160104.815195
The remainder is 35 after subtracting 2435 from 2470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 15:
The number 487 fits into 350 0 times, leaving a remainder of 350.
The number 0 becomes the next digit in our result. 
Result so far: 160104.815195
If we subtract 0 from 350, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 16:
If we divide 3500 by 487, we get 7 and a remainder of 91.
The next digit of our result is 7. 
Result so far: 160104.81519507
Subtract 3409 from 3500 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

After the division, we end up with 160104.81519507 and a remainder of 9.1e-08.
