We look at the division of 76029279 by 221 
We want to figure out the number of times 76029279 can be divided by 221.

Step 1:
221 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 221

Step 2:
221 can be fit into 76 0 times, resulting in a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Grab the next digit (0) from the dividend, add it to 76, then carry on: 760 / 221

Going ahead to step 3:
760 divided by 221 is 3 with a remainder of 97.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 97 after subtracting 663 from 760.
Take the next digit (2) from the dividend and append it to 97, then repeat: 972 / 221

Advancing to step 4:
972 divided by 221 is 4 with a remainder of 88.
Put 4 as the next digit of the answer. 
Result so far: 34.0
The remainder is 88 after subtracting 884 from 972.
Append the next digit (9) from the dividend to 88 and continue with: 889 / 221

Step 5:
221 can be fit into 889 4 times, resulting in a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 344.0
If we subtract 884 from 889, we get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 221

Step 6:
52 divided by 221 is 0 with a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 3440.0
If we subtract 0 from 52, we get 52.
Include the next digit (7) from the dividend after 52, then repeat: 527 / 221

Step 7:
527 divided by 221 is 2 with a remainder of 85.
Put 2 as the next digit of the answer. 
Result so far: 34402.0
Subtracting 442 from 527 leaves us with 85.
Include the next digit (9) from the dividend after 85, then repeat: 859 / 221

Going ahead to step 8:
221 can be fit into 859 3 times, resulting in a remainder of 196.
Write down 3 as next digit of the result. 
Result so far: 344023.0
Deduct 663 from 859 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 9:
221 can be fit into 1960 8 times, resulting in a remainder of 192.
Put 8 as the next digit of the answer. 
Result so far: 344023.8
Subtracting 1768 from 1960 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 10:
221 can be fit into 1920 8 times, resulting in a remainder of 152.
The next digit of our result is 8. 
Result so far: 344023.88
The remainder is 152 after subtracting 1768 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

The final result is 344023.88 with a remainder of 0.152.
