76407912 ÷ 493 
We want to figure out the number of times 76407912 can be divided by 493.

Going ahead to step 1:
If we divide 7 by 493, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 493

Advancing to step 2:
76 divided by 493 is 0 with a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Take the next digit (4) from the dividend and append it to 76, then repeat: 764 / 493

On to step 3:
493 goes into 764 1 times with a remainder of 271.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 493 from 764, we get 271.
Take the next digit (0) from the dividend and append it to 271, then repeat: 2710 / 493

Step 4:
If we divide 2710 by 493, we get 5 and a remainder of 245.
The next digit of our result is 5. 
Result so far: 15.0
If we take 2465 away from 2710, we end up with 245.
Append the next digit (7) from the dividend to 245 and continue with: 2457 / 493

On to step 5:
When dividing 2457 by 493, we get 4 with a remainder of 485.
Put 4 as the next digit of the answer. 
Result so far: 154.0
Subtracting 1972 from 2457 leaves us with 485.
Append the next digit (9) from the dividend to 485 and continue with: 4859 / 493

Going ahead to step 6:
If we divide 4859 by 493, we get 9 and a remainder of 422.
Put 9 as the next digit of the answer. 
Result so far: 1549.0
If we take 4437 away from 4859, we end up with 422.
Bring next digit (1) of the dividend behind the 422 and repeat the process: 4221 / 493

Advancing to step 7:
The number 493 fits into 4221 8 times, leaving a remainder of 277.
Record the quotient 8 as the next digit in the result. 
Result so far: 15498.0
Deduct 3944 from 4221 and we're left with 277.
Grab the next digit (2) from the dividend, add it to 277, then carry on: 2772 / 493

On to step 8:
493 goes into 2772 5 times with a remainder of 307.
The next digit of our result is 5. 
Result so far: 154985.0
Subtract 2465 from 2772 to get 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Let's proceed to step 9:
493 can be fit into 3070 6 times, resulting in a remainder of 112.
Write down 6 as next digit of the result. 
Result so far: 154985.6
If we take 2958 away from 3070, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 10:
493 can be fit into 1120 2 times, resulting in a remainder of 134.
Record the quotient 2 as the next digit in the result. 
Result so far: 154985.62
If we subtract 986 from 1120, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Going ahead to step 11:
1340 divided by 493 is 2 with a remainder of 354.
Record the quotient 2 as the next digit in the result. 
Result so far: 154985.622
If we subtract 986 from 1340, we get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

After the division, we end up with 154985.622 and a remainder of 0.0354.
