250911 ÷ 78 
We want to figure out the number of times 250911 can be divided by 78.

On to step 1:
If we divide 2 by 78, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 78

Advancing to step 2:
25 divided by 78 is 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Include the next digit (0) from the dividend after 25, then repeat: 250 / 78

Step 3:
If we divide 250 by 78, we get 3 and a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 234 from 250 and we're left with 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 78

On to step 4:
78 goes into 169 2 times with a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
Deduct 156 from 169 and we're left with 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 78

Step 5:
The number 78 fits into 131 1 times, leaving a remainder of 53.
Write down 1 as next digit of the result. 
Result so far: 321.0
If we take 78 away from 131, we end up with 53.
Bring next digit (1) of the dividend behind the 53 and repeat the process: 531 / 78

Step 6:
When dividing 531 by 78, we get 6 with a remainder of 63.
The next digit of our result is 6. 
Result so far: 3216.0
Subtract 468 from 531 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 7:
When dividing 630 by 78, we get 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 3216.8
Subtract 624 from 630 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
The number 78 fits into 60 0 times, leaving a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 3216.8
Subtract 0 from 60 to 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 9:
If we divide 600 by 78, we get 7 and a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 3216.807
Subtract 546 from 600 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 10:
When dividing 540 by 78, we get 6 with a remainder of 72.
The next digit of our result is 6. 
Result so far: 3216.8076
If we subtract 468 from 540, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 11:
78 goes into 720 9 times with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 3216.80769
If we subtract 702 from 720, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 12:
78 can be fit into 180 2 times, resulting in a remainder of 24.
The next digit of our result is 2. 
Result so far: 3216.807692
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
The number 78 fits into 240 3 times, leaving a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 3216.8076923
If we take 234 away from 240, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 14:
78 goes into 60 0 times with a remainder of 60.
The next digit of our result is 0. 
Result so far: 3216.8076923
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 3216.8076923 with a remainder of 6e-08.
