77719686 ÷ 721 
Let's see how many times 721 fits into 77719686.

Moving on to step 1:
When dividing 7 by 721, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 721

Step 2:
721 can be fit into 77 0 times, resulting in a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Grab the next digit (7) from the dividend, add it to 77, then carry on: 777 / 721

Going ahead to step 3:
721 goes into 777 1 times with a remainder of 56.
The next digit of our result is 1. 
Result so far: 1.0
If we take 721 away from 777, we end up with 56.
Grab the next digit (1) from the dividend, add it to 56, then carry on: 561 / 721

On to step 4:
561 divided by 721 is 0 with a remainder of 561.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 561 leaves us with 561.
Bring next digit (9) of the dividend behind the 561 and repeat the process: 5619 / 721

Step 5:
When dividing 5619 by 721, we get 7 with a remainder of 572.
Put 7 as the next digit of the answer. 
Result so far: 107.0
If we take 5047 away from 5619, we end up with 572.
Take the next digit (6) from the dividend and append it to 572, then repeat: 5726 / 721

On to step 6:
721 can be fit into 5726 7 times, resulting in a remainder of 679.
Put 7 as the next digit of the answer. 
Result so far: 1077.0
The remainder is 679 after subtracting 5047 from 5726.
Take the next digit (8) from the dividend and append it to 679, then repeat: 6798 / 721

On to step 7:
If we divide 6798 by 721, we get 9 and a remainder of 309.
The number 9 becomes the next digit in our result. 
Result so far: 10779.0
Deduct 6489 from 6798 and we're left with 309.
Include the next digit (6) from the dividend after 309, then repeat: 3096 / 721

Step 8:
If we divide 3096 by 721, we get 4 and a remainder of 212.
Record the quotient 4 as the next digit in the result. 
Result so far: 107794.0
If we subtract 2884 from 3096, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 9:
The number 721 fits into 2120 2 times, leaving a remainder of 678.
Record the quotient 2 as the next digit in the result. 
Result so far: 107794.2
Subtract 1442 from 2120 to get 678.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

On to step 10:
The number 721 fits into 6780 9 times, leaving a remainder of 291.
The number 9 becomes the next digit in our result. 
Result so far: 107794.29
Subtracting 6489 from 6780 leaves us with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Let's proceed to step 11:
721 goes into 2910 4 times with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 107794.294
If we take 2884 away from 2910, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 12:
When dividing 260 by 721, we get 0 with a remainder of 260.
Use 0 as the next digit of our solution. 
Result so far: 107794.294
If we subtract 0 from 260, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 13:
The number 721 fits into 2600 3 times, leaving a remainder of 437.
Write down 3 as next digit of the result. 
Result so far: 107794.29403
If we take 2163 away from 2600, we end up with 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Moving on to step 14:
The number 721 fits into 4370 6 times, leaving a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 107794.294036
If we subtract 4326 from 4370, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 15:
721 can be fit into 440 0 times, resulting in a remainder of 440.
Write down 0 as next digit of the result. 
Result so far: 107794.294036
Subtracting 0 from 440 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 16:
If we divide 4400 by 721, we get 6 and a remainder of 74.
Use 6 as the next digit of our solution. 
Result so far: 107794.29403606
Subtracting 4326 from 4400 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

After the division, we end up with 107794.29403606 and a remainder of 7.4e-08.
