76992764 ÷ 645 
Let's see how many times 645 fits into 76992764.

On to step 1:
645 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 645

Step 2:
645 goes into 76 0 times with a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 76 leaves us with 76.
Append the next digit (9) from the dividend to 76 and continue with: 769 / 645

Step 3:
When dividing 769 by 645, we get 1 with a remainder of 124.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 645 from 769 to get 124.
Append the next digit (9) from the dividend to 124 and continue with: 1249 / 645

Going ahead to step 4:
645 can be fit into 1249 1 times, resulting in a remainder of 604.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 645 from 1249 to get 604.
Fetch the next digit (2) from the dividend, attach it to 604 and continue: 6042 / 645

On to step 5:
645 goes into 6042 9 times with a remainder of 237.
The next digit of our result is 9. 
Result so far: 119.0
Subtracting 5805 from 6042 leaves us with 237.
Take the next digit (7) from the dividend and append it to 237, then repeat: 2377 / 645

On to step 6:
2377 divided by 645 is 3 with a remainder of 442.
Record the quotient 3 as the next digit in the result. 
Result so far: 1193.0
Subtracting 1935 from 2377 leaves us with 442.
Take the next digit (6) from the dividend and append it to 442, then repeat: 4426 / 645

Moving on to step 7:
645 goes into 4426 6 times with a remainder of 556.
The number 6 becomes the next digit in our result. 
Result so far: 11936.0
Subtract 3870 from 4426 to get 556.
Append the next digit (4) from the dividend to 556 and continue with: 5564 / 645

On to step 8:
The number 645 fits into 5564 8 times, leaving a remainder of 404.
The next digit of our result is 8. 
Result so far: 119368.0
If we take 5160 away from 5564, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Moving on to step 9:
If we divide 4040 by 645, we get 6 and a remainder of 170.
Record the quotient 6 as the next digit in the result. 
Result so far: 119368.6
The remainder is 170 after subtracting 3870 from 4040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 10:
1700 divided by 645 is 2 with a remainder of 410.
Record the quotient 2 as the next digit in the result. 
Result so far: 119368.62
The remainder is 410 after subtracting 1290 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

On to step 11:
645 can be fit into 4100 6 times, resulting in a remainder of 230.
The next digit of our result is 6. 
Result so far: 119368.626
If we take 3870 away from 4100, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 12:
If we divide 2300 by 645, we get 3 and a remainder of 365.
Write down 3 as next digit of the result. 
Result so far: 119368.6263
Deduct 1935 from 2300 and we're left with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Advancing to step 13:
The number 645 fits into 3650 5 times, leaving a remainder of 425.
Record the quotient 5 as the next digit in the result. 
Result so far: 119368.62635
The remainder is 425 after subtracting 3225 from 3650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Step 14:
4250 divided by 645 is 6 with a remainder of 380.
The number 6 becomes the next digit in our result. 
Result so far: 119368.626356
Subtracting 3870 from 4250 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 15:
645 can be fit into 3800 5 times, resulting in a remainder of 575.
Put 5 as the next digit of the answer. 
Result so far: 119368.6263565
The remainder is 575 after subtracting 3225 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Step 16:
645 goes into 5750 8 times with a remainder of 590.
The next digit of our result is 8. 
Result so far: 119368.62635658
The remainder is 590 after subtracting 5160 from 5750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

The final outcome is 119368.62635658, with a leftover of 5.9e-07.
