77799721 ÷ 316 
We want to divide 77799721 by 316.

Step 1:
The number 316 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 316

Step 2:
77 divided by 316 is 0 with 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.
Bring next digit (7) of the dividend behind the 77 and repeat the process: 777 / 316

Moving on to step 3:
316 can be fit into 777 2 times, resulting in a remainder of 145.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 145 after subtracting 632 from 777.
Fetch the next digit (9) from the dividend, attach it to 145 and continue: 1459 / 316

On to step 4:
1459 divided by 316 is 4 with a remainder of 195.
Write down 4 as next digit of the result. 
Result so far: 24.0
If we subtract 1264 from 1459, we get 195.
Grab the next digit (9) from the dividend, add it to 195, then carry on: 1959 / 316

On to step 5:
316 goes into 1959 6 times with a remainder of 63.
Write down 6 as next digit of the result. 
Result so far: 246.0
The remainder is 63 after subtracting 1896 from 1959.
Include the next digit (7) from the dividend after 63, then repeat: 637 / 316

Advancing to step 6:
When dividing 637 by 316, we get 2 with a remainder of 5.
The next digit of our result is 2. 
Result so far: 2462.0
If we subtract 632 from 637, we get 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 316

Advancing to step 7:
316 can be fit into 52 0 times, resulting in a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 24620.0
Subtracting 0 from 52 leaves us with 52.
Bring next digit (1) of the dividend behind the 52 and repeat the process: 521 / 316

Let's proceed to step 8:
316 goes into 521 1 times with a remainder of 205.
Write down 1 as next digit of the result. 
Result so far: 246201.0
The remainder is 205 after subtracting 316 from 521.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Step 9:
When dividing 2050 by 316, we get 6 with a remainder of 154.
Put 6 as the next digit of the answer. 
Result so far: 246201.6
If we take 1896 away from 2050, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

On to step 10:
1540 divided by 316 is 4 with a remainder of 276.
The number 4 becomes the next digit in our result. 
Result so far: 246201.64
If we take 1264 away from 1540, we end up with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Moving on to step 11:
The number 316 fits into 2760 8 times, leaving a remainder of 232.
Use 8 as the next digit of our solution. 
Result so far: 246201.648
Subtracting 2528 from 2760 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Let's proceed to step 12:
When dividing 2320 by 316, we get 7 with a remainder of 108.
Write down 7 as next digit of the result. 
Result so far: 246201.6487
If we subtract 2212 from 2320, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 13:
1080 divided by 316 is 3 with a remainder of 132.
Write down 3 as next digit of the result. 
Result so far: 246201.64873
If we subtract 948 from 1080, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 14:
When dividing 1320 by 316, we get 4 with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 246201.648734
The remainder is 56 after subtracting 1264 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 15:
If we divide 560 by 316, we get 1 and a remainder of 244.
The number 1 becomes the next digit in our result. 
Result so far: 246201.6487341
Subtracting 316 from 560 leaves us with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Moving on to step 16:
The number 316 fits into 2440 7 times, leaving a remainder of 228.
The next digit of our result is 7. 
Result so far: 246201.64873417
If we take 2212 away from 2440, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Our division results in 246201.64873417 with a remaining 2.28e-07.
