78757781 ÷ 487 
We want to figure out the number of times 78757781 can be divided by 487.

Moving on 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
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 487

Advancing to step 2:
When dividing 78 by 487, we get 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Fetch the next digit (7) from the dividend, attach it to 78 and continue: 787 / 487

Step 3:
The number 487 fits into 787 1 times, leaving a remainder of 300.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 487 from 787, we get 300.
Include the next digit (5) from the dividend after 300, then repeat: 3005 / 487

Going ahead to step 4:
If we divide 3005 by 487, we get 6 and a remainder of 83.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 2922 from 3005 leaves us with 83.
Bring next digit (7) of the dividend behind the 83 and repeat the process: 837 / 487

Step 5:
When dividing 837 by 487, we get 1 with a remainder of 350.
Use 1 as the next digit of our solution. 
Result so far: 161.0
If we take 487 away from 837, we end up with 350.
Bring next digit (7) of the dividend behind the 350 and repeat the process: 3507 / 487

Moving on to step 6:
3507 divided by 487 is 7 with a remainder of 98.
Write down 7 as next digit of the result. 
Result so far: 1617.0
Deduct 3409 from 3507 and we're left with 98.
Append the next digit (8) from the dividend to 98 and continue with: 988 / 487

Advancing to step 7:
When dividing 988 by 487, we get 2 with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 16172.0
Subtract 974 from 988 to get 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 487

Moving on to step 8:
If we divide 141 by 487, we get 0 and a remainder of 141.
Record the quotient 0 as the next digit in the result. 
Result so far: 161720.0
Subtract 0 from 141 to get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Step 9:
1410 divided by 487 is 2 with a remainder of 436.
Use 2 as the next digit of our solution. 
Result so far: 161720.2
Deduct 974 from 1410 and we're left with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Step 10:
The number 487 fits into 4360 8 times, leaving a remainder of 464.
Use 8 as the next digit of our solution. 
Result so far: 161720.28
The remainder is 464 after subtracting 3896 from 4360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Advancing to step 11:
487 can be fit into 4640 9 times, resulting in a remainder of 257.
The number 9 becomes the next digit in our result. 
Result so far: 161720.289
Subtracting 4383 from 4640 leaves us with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

On to step 12:
2570 divided by 487 is 5 with a remainder of 135.
Write down 5 as next digit of the result. 
Result so far: 161720.2895
If we take 2435 away from 2570, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 13:
487 goes into 1350 2 times with a remainder of 376.
Use 2 as the next digit of our solution. 
Result so far: 161720.28952
Subtract 974 from 1350 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Moving on to step 14:
487 goes into 3760 7 times with a remainder of 351.
Use 7 as the next digit of our solution. 
Result so far: 161720.289527
Subtract 3409 from 3760 to get 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

On to step 15:
The number 487 fits into 3510 7 times, leaving a remainder of 101.
The number 7 becomes the next digit in our result. 
Result so far: 161720.2895277
Deduct 3409 from 3510 and we're left with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

The final result is 161720.2895277 with a remainder of 1.01e-06.
