We look at the division of 78406873 by 767 
Our goal is to divide 78406873 by 767.

Step 1:
When dividing 7 by 767, 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.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 767

Going ahead to step 2:
If we divide 78 by 767, we get 0 and a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Include the next digit (4) from the dividend after 78, then repeat: 784 / 767

Moving on to step 3:
767 goes into 784 1 times with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 767 from 784 leaves us with 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 767

Moving on to step 4:
When dividing 170 by 767, we get 0 with a remainder of 170.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 170 to get 170.
Include the next digit (6) from the dividend after 170, then repeat: 1706 / 767

On to step 5:
1706 divided by 767 is 2 with a remainder of 172.
Write down 2 as next digit of the result. 
Result so far: 102.0
Subtract 1534 from 1706 to get 172.
Bring next digit (8) of the dividend behind the 172 and repeat the process: 1728 / 767

Advancing to step 6:
If we divide 1728 by 767, we get 2 and a remainder of 194.
The number 2 becomes the next digit in our result. 
Result so far: 1022.0
Subtracting 1534 from 1728 leaves us with 194.
Include the next digit (7) from the dividend after 194, then repeat: 1947 / 767

Let's proceed to step 7:
767 goes into 1947 2 times with a remainder of 413.
Record the quotient 2 as the next digit in the result. 
Result so far: 10222.0
If we take 1534 away from 1947, we end up with 413.
Include the next digit (3) from the dividend after 413, then repeat: 4133 / 767

Let's proceed to step 8:
767 goes into 4133 5 times with a remainder of 298.
Write down 5 as next digit of the result. 
Result so far: 102225.0
Subtract 3835 from 4133 to get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Advancing to step 9:
767 goes into 2980 3 times with a remainder of 679.
Use 3 as the next digit of our solution. 
Result so far: 102225.3
Subtract 2301 from 2980 to get 679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

Going ahead to step 10:
767 goes into 6790 8 times with a remainder of 654.
Write down 8 as next digit of the result. 
Result so far: 102225.38
Subtracting 6136 from 6790 leaves us with 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Advancing to step 11:
767 goes into 6540 8 times with a remainder of 404.
The number 8 becomes the next digit in our result. 
Result so far: 102225.388
Subtract 6136 from 6540 to get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

The quotient of the division is 102225.388, and the remainder is 0.0404.
