We look at the division of 78766779 by 487 
We want to figure out the number of times 78766779 can be divided by 487.

Going ahead to step 1:
If we divide 7 by 487, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 487

Moving on to step 2:
487 goes into 78 0 times with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Bring next digit (7) of the dividend behind the 78 and repeat the process: 787 / 487

Going ahead to step 3:
487 can be fit into 787 1 times, resulting in a remainder of 300.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 487 from 787 leaves us with 300.
Fetch the next digit (6) from the dividend, attach it to 300 and continue: 3006 / 487

On to step 4:
3006 divided by 487 is 6 with a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we subtract 2922 from 3006, we get 84.
Append the next digit (6) from the dividend to 84 and continue with: 846 / 487

Advancing to step 5:
487 can be fit into 846 1 times, resulting in a remainder of 359.
Write down 1 as next digit of the result. 
Result so far: 161.0
Subtract 487 from 846 to get 359.
Include the next digit (7) from the dividend after 359, then repeat: 3597 / 487

Advancing to step 6:
3597 divided by 487 is 7 with a remainder of 188.
The number 7 becomes the next digit in our result. 
Result so far: 1617.0
If we subtract 3409 from 3597, we get 188.
Append the next digit (7) from the dividend to 188 and continue with: 1887 / 487

Moving on to step 7:
The number 487 fits into 1887 3 times, leaving a remainder of 426.
Record the quotient 3 as the next digit in the result. 
Result so far: 16173.0
Subtracting 1461 from 1887 leaves us with 426.
Fetch the next digit (9) from the dividend, attach it to 426 and continue: 4269 / 487

Advancing to step 8:
4269 divided by 487 is 8 with a remainder of 373.
The number 8 becomes the next digit in our result. 
Result so far: 161738.0
If we take 3896 away from 4269, we end up with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

On to step 9:
When dividing 3730 by 487, we get 7 with a remainder of 321.
Put 7 as the next digit of the answer. 
Result so far: 161738.7
Subtract 3409 from 3730 to get 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

On to step 10:
The number 487 fits into 3210 6 times, leaving a remainder of 288.
The number 6 becomes the next digit in our result. 
Result so far: 161738.76
Deduct 2922 from 3210 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 11:
487 can be fit into 2880 5 times, resulting in a remainder of 445.
Use 5 as the next digit of our solution. 
Result so far: 161738.765
Subtract 2435 from 2880 to get 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

On to step 12:
487 goes into 4450 9 times with a remainder of 67.
Write down 9 as next digit of the result. 
Result so far: 161738.7659
Subtracting 4383 from 4450 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 13:
If we divide 670 by 487, we get 1 and a remainder of 183.
Write down 1 as next digit of the result. 
Result so far: 161738.76591
The remainder is 183 after subtracting 487 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Step 14:
487 goes into 1830 3 times with a remainder of 369.
Use 3 as the next digit of our solution. 
Result so far: 161738.765913
Subtracting 1461 from 1830 leaves us with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Moving on to step 15:
The number 487 fits into 3690 7 times, leaving a remainder of 281.
Put 7 as the next digit of the answer. 
Result so far: 161738.7659137
If we take 3409 away from 3690, we end up with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

On to step 16:
2810 divided by 487 is 5 with a remainder of 375.
Write down 5 as next digit of the result. 
Result so far: 161738.76591375
If we take 2435 away from 2810, we end up with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

The final outcome is 161738.76591375, with a leftover of 3.75e-07.
