Let's divide 78821350 by 50
Let's see how many times 50 fits into 78821350.

On to step 1:
50 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 50

Moving on to step 2:
78 divided by 50 is 1 with a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 50 from 78 leaves us with 28.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 50

Moving on to step 3:
If we divide 288 by 50, we get 5 and a remainder of 38.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 250 from 288 and we're left with 38.
Grab the next digit (2) from the dividend, add it to 38, then carry on: 382 / 50

On to step 4:
If we divide 382 by 50, we get 7 and a remainder of 32.
The next digit of our result is 7. 
Result so far: 157.0
Subtracting 350 from 382 leaves us with 32.
Fetch the next digit (1) from the dividend, attach it to 32 and continue: 321 / 50

Moving on to step 5:
When dividing 321 by 50, we get 6 with a remainder of 21.
The number 6 becomes the next digit in our result. 
Result so far: 1576.0
Deduct 300 from 321 and we're left with 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 50

On to step 6:
50 goes into 213 4 times with a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 15764.0
If we take 200 away from 213, we end up with 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 50

Advancing to step 7:
50 can be fit into 135 2 times, resulting in a remainder of 35.
Put 2 as the next digit of the answer. 
Result so far: 157642.0
Subtract 100 from 135 to get 35.
Include the next digit (0) from the dividend after 35, then repeat: 350 / 50

Step 8:
50 can be fit into 350 7 times, resulting in a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 1576427.0
Subtract 350 from 350 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
50 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 1576427.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
The number 50 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1576427.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 1576427.0 and a remainder of 0.0.
