We're dividing 78543911 by 820 
Our goal is to divide 78543911 by 820.

Advancing to step 1:
820 goes into 7 0 times 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.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 820

Advancing to step 2:
78 divided by 820 is 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Fetch the next digit (5) from the dividend, attach it to 78 and continue: 785 / 820

Going ahead to step 3:
820 can be fit into 785 0 times, resulting in a remainder of 785.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 785 after subtracting 0 from 785.
Bring next digit (4) of the dividend behind the 785 and repeat the process: 7854 / 820

Let's proceed to step 4:
7854 divided by 820 is 9 with a remainder of 474.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 7380 from 7854 leaves us with 474.
Include the next digit (3) from the dividend after 474, then repeat: 4743 / 820

On to step 5:
820 can be fit into 4743 5 times, resulting in a remainder of 643.
Use 5 as the next digit of our solution. 
Result so far: 95.0
If we take 4100 away from 4743, we end up with 643.
Grab the next digit (9) from the dividend, add it to 643, then carry on: 6439 / 820

On to step 6:
820 goes into 6439 7 times with a remainder of 699.
Record the quotient 7 as the next digit in the result. 
Result so far: 957.0
If we take 5740 away from 6439, we end up with 699.
Include the next digit (1) from the dividend after 699, then repeat: 6991 / 820

Advancing to step 7:
820 goes into 6991 8 times with a remainder of 431.
Put 8 as the next digit of the answer. 
Result so far: 9578.0
Subtract 6560 from 6991 to get 431.
Bring next digit (1) of the dividend behind the 431 and repeat the process: 4311 / 820

Advancing to step 8:
The number 820 fits into 4311 5 times, leaving a remainder of 211.
The number 5 becomes the next digit in our result. 
Result so far: 95785.0
Subtract 4100 from 4311 to get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

On to step 9:
When dividing 2110 by 820, we get 2 with a remainder of 470.
Put 2 as the next digit of the answer. 
Result so far: 95785.2
If we take 1640 away from 2110, we end up with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

On to step 10:
4700 divided by 820 is 5 with a remainder of 600.
Record the quotient 5 as the next digit in the result. 
Result so far: 95785.25
Subtract 4100 from 4700 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 11:
6000 divided by 820 is 7 with a remainder of 260.
Put 7 as the next digit of the answer. 
Result so far: 95785.257
If we subtract 5740 from 6000, 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.

Moving on to step 12:
If we divide 2600 by 820, we get 3 and a remainder of 140.
Record the quotient 3 as the next digit in the result. 
Result so far: 95785.2573
If we subtract 2460 from 2600, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 13:
820 can be fit into 1400 1 times, resulting in a remainder of 580.
Record the quotient 1 as the next digit in the result. 
Result so far: 95785.25731
If we subtract 820 from 1400, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Advancing to step 14:
820 goes into 5800 7 times with a remainder of 60.
Use 7 as the next digit of our solution. 
Result so far: 95785.257317
If we subtract 5740 from 5800, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 15:
600 divided by 820 is 0 with a remainder of 600.
The number 0 becomes the next digit in our result. 
Result so far: 95785.257317
Deduct 0 from 600 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 16:
The number 820 fits into 6000 7 times, leaving a remainder of 260.
The number 7 becomes the next digit in our result. 
Result so far: 95785.25731707
Deduct 5740 from 6000 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Our division results in 95785.25731707 with a remaining 2.6e-07.
