We're dividing 50302115 by 978 
We want to figure out the number of times 50302115 can be divided by 978.

On to step 1:
978 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 978

Moving on to step 2:
When dividing 50 by 978, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Bring next digit (3) of the dividend behind the 50 and repeat the process: 503 / 978

On to step 3:
The number 978 fits into 503 0 times, leaving a remainder of 503.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 503, we end up with 503.
Fetch the next digit (0) from the dividend, attach it to 503 and continue: 5030 / 978

Advancing to step 4:
978 goes into 5030 5 times with a remainder of 140.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 4890 from 5030 and we're left with 140.
Grab the next digit (2) from the dividend, add it to 140, then carry on: 1402 / 978

Let's proceed to step 5:
978 goes into 1402 1 times with a remainder of 424.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
The remainder is 424 after subtracting 978 from 1402.
Include the next digit (1) from the dividend after 424, then repeat: 4241 / 978

On to step 6:
The number 978 fits into 4241 4 times, leaving a remainder of 329.
The next digit of our result is 4. 
Result so far: 514.0
Subtract 3912 from 4241 to get 329.
Include the next digit (1) from the dividend after 329, then repeat: 3291 / 978

Let's proceed to step 7:
978 goes into 3291 3 times with a remainder of 357.
Write down 3 as next digit of the result. 
Result so far: 5143.0
If we subtract 2934 from 3291, we get 357.
Include the next digit (5) from the dividend after 357, then repeat: 3575 / 978

Going ahead to step 8:
If we divide 3575 by 978, we get 3 and a remainder of 641.
Record the quotient 3 as the next digit in the result. 
Result so far: 51433.0
Subtract 2934 from 3575 to get 641.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6410, and continue the process.

On to step 9:
6410 divided by 978 is 6 with a remainder of 542.
The number 6 becomes the next digit in our result. 
Result so far: 51433.6
If we subtract 5868 from 6410, we get 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Let's proceed to step 10:
978 can be fit into 5420 5 times, resulting in a remainder of 530.
Write down 5 as next digit of the result. 
Result so far: 51433.65
Deduct 4890 from 5420 and we're left with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Advancing to step 11:
When dividing 5300 by 978, we get 5 with a remainder of 410.
Record the quotient 5 as the next digit in the result. 
Result so far: 51433.655
Deduct 4890 from 5300 and we're left with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

In conclusion, the division gives 51433.655 with a balance of 0.041.
