We look at the division of 783821 by 77 
Our goal is to divide 783821 by 77.

Step 1:
77 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 77

Step 2:
77 can be fit into 78 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 77 from 78, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 77

On to step 3:
13 divided by 77 is 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 13 and we're left with 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 77

Advancing to step 4:
77 goes into 138 1 times with a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
Deduct 77 from 138 and we're left with 61.
Fetch the next digit (2) from the dividend, attach it to 61 and continue: 612 / 77

Advancing to step 5:
When dividing 612 by 77, we get 7 with a remainder of 73.
The next digit of our result is 7. 
Result so far: 1017.0
If we subtract 539 from 612, we get 73.
Grab the next digit (1) from the dividend, add it to 73, then carry on: 731 / 77

Let's proceed to step 6:
77 can be fit into 731 9 times, resulting in a remainder of 38.
The next digit of our result is 9. 
Result so far: 10179.0
If we subtract 693 from 731, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 7:
If we divide 380 by 77, we get 4 and a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 10179.4
Subtracting 308 from 380 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 8:
720 divided by 77 is 9 with a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 10179.49
Deduct 693 from 720 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 9:
270 divided by 77 is 3 with a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 10179.493
Subtract 231 from 270 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 10:
If we divide 390 by 77, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 10179.4935
Subtracting 385 from 390 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 11:
50 divided by 77 is 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 10179.4935
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 12:
77 can be fit into 500 6 times, resulting in a remainder of 38.
Put 6 as the next digit of the answer. 
Result so far: 10179.493506
The remainder is 38 after subtracting 462 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 13:
When dividing 380 by 77, we get 4 with a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 10179.4935064
The remainder is 72 after subtracting 308 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 14:
77 can be fit into 720 9 times, resulting in a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 10179.49350649
If we subtract 693 from 720, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

In conclusion, the division gives 10179.49350649 with a balance of 2.7e-08.
