Let's divide 30771584 by 721
We want to figure out the number of times 30771584 can be divided by 721.

On to step 1:
If we divide 3 by 721, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 721

Going ahead to step 2:
30 divided by 721 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Bring next digit (7) of the dividend behind the 30 and repeat the process: 307 / 721

Going ahead to step 3:
If we divide 307 by 721, we get 0 and a remainder of 307.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 307 after subtracting 0 from 307.
Append the next digit (7) from the dividend to 307 and continue with: 3077 / 721

Step 4:
3077 divided by 721 is 4 with a remainder of 193.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 2884 away from 3077, we end up with 193.
Include the next digit (1) from the dividend after 193, then repeat: 1931 / 721

Advancing to step 5:
721 goes into 1931 2 times with a remainder of 489.
Use 2 as the next digit of our solution. 
Result so far: 42.0
Deduct 1442 from 1931 and we're left with 489.
Grab the next digit (5) from the dividend, add it to 489, then carry on: 4895 / 721

Step 6:
4895 divided by 721 is 6 with a remainder of 569.
Record the quotient 6 as the next digit in the result. 
Result so far: 426.0
Subtract 4326 from 4895 to get 569.
Append the next digit (8) from the dividend to 569 and continue with: 5698 / 721

Moving on to step 7:
721 can be fit into 5698 7 times, resulting in a remainder of 651.
The number 7 becomes the next digit in our result. 
Result so far: 4267.0
If we subtract 5047 from 5698, we get 651.
Append the next digit (4) from the dividend to 651 and continue with: 6514 / 721

Step 8:
When dividing 6514 by 721, we get 9 with a remainder of 25.
Put 9 as the next digit of the answer. 
Result so far: 42679.0
If we subtract 6489 from 6514, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 9:
250 divided by 721 is 0 with a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 42679.0
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 10:
The number 721 fits into 2500 3 times, leaving a remainder of 337.
Use 3 as the next digit of our solution. 
Result so far: 42679.03
If we take 2163 away from 2500, we end up with 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Moving on to step 11:
If we divide 3370 by 721, we get 4 and a remainder of 486.
The number 4 becomes the next digit in our result. 
Result so far: 42679.034
Deduct 2884 from 3370 and we're left with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Let's proceed to step 12:
If we divide 4860 by 721, we get 6 and a remainder of 534.
Use 6 as the next digit of our solution. 
Result so far: 42679.0346
Deduct 4326 from 4860 and we're left with 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Step 13:
When dividing 5340 by 721, we get 7 with a remainder of 293.
Write down 7 as next digit of the result. 
Result so far: 42679.03467
Subtract 5047 from 5340 to get 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Advancing to step 14:
721 can be fit into 2930 4 times, resulting in a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 42679.034674
If we take 2884 away from 2930, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 15:
If we divide 460 by 721, we get 0 and a remainder of 460.
The number 0 becomes the next digit in our result. 
Result so far: 42679.034674
The remainder is 460 after subtracting 0 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 16:
When dividing 4600 by 721, we get 6 with a remainder of 274.
Use 6 as the next digit of our solution. 
Result so far: 42679.03467406
Subtract 4326 from 4600 to get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

The quotient of the division is 42679.03467406, and the remainder is 2.74e-07.
