Let's divide 77796176 by 821
Our goal is to divide 77796176 by 821.

Let's proceed to step 1:
When dividing 7 by 821, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 821

Moving on to step 2:
The number 821 fits into 77 0 times, leaving a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Include the next digit (7) from the dividend after 77, then repeat: 777 / 821

On to step 3:
If we divide 777 by 821, we get 0 and a remainder of 777.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 777, we get 777.
Append the next digit (9) from the dividend to 777 and continue with: 7779 / 821

Moving on to step 4:
When dividing 7779 by 821, we get 9 with a remainder of 390.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 7389 from 7779, we get 390.
Include the next digit (6) from the dividend after 390, then repeat: 3906 / 821

Let's proceed to step 5:
If we divide 3906 by 821, we get 4 and a remainder of 622.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
The remainder is 622 after subtracting 3284 from 3906.
Fetch the next digit (1) from the dividend, attach it to 622 and continue: 6221 / 821

Moving on to step 6:
6221 divided by 821 is 7 with a remainder of 474.
Record the quotient 7 as the next digit in the result. 
Result so far: 947.0
If we subtract 5747 from 6221, we get 474.
Fetch the next digit (7) from the dividend, attach it to 474 and continue: 4747 / 821

Step 7:
821 can be fit into 4747 5 times, resulting in a remainder of 642.
The number 5 becomes the next digit in our result. 
Result so far: 9475.0
If we subtract 4105 from 4747, we get 642.
Include the next digit (6) from the dividend after 642, then repeat: 6426 / 821

On to step 8:
If we divide 6426 by 821, we get 7 and a remainder of 679.
The number 7 becomes the next digit in our result. 
Result so far: 94757.0
The remainder is 679 after subtracting 5747 from 6426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

Step 9:
When dividing 6790 by 821, we get 8 with a remainder of 222.
Write down 8 as next digit of the result. 
Result so far: 94757.8
If we take 6568 away from 6790, we end up with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Let's proceed to step 10:
821 can be fit into 2220 2 times, resulting in a remainder of 578.
The next digit of our result is 2. 
Result so far: 94757.82
If we take 1642 away from 2220, we end up with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Step 11:
The number 821 fits into 5780 7 times, leaving a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 94757.827
Deduct 5747 from 5780 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 12:
821 goes into 330 0 times with a remainder of 330.
Put 0 as the next digit of the answer. 
Result so far: 94757.827
Subtracting 0 from 330 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Step 13:
The number 821 fits into 3300 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 94757.82704
Deduct 3284 from 3300 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
821 can be fit into 160 0 times, resulting in a remainder of 160.
Put 0 as the next digit of the answer. 
Result so far: 94757.82704
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 15:
If we divide 1600 by 821, we get 1 and a remainder of 779.
The next digit of our result is 1. 
Result so far: 94757.8270401
If we take 821 away from 1600, we end up with 779.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7790, and continue the process.

On to step 16:
When dividing 7790 by 821, we get 9 with a remainder of 401.
Write down 9 as next digit of the result. 
Result so far: 94757.82704019
If we subtract 7389 from 7790, we get 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

After the division, we end up with 94757.82704019 and a remainder of 4.01e-07.
