We look at the division of 51680441 by 978 
We're looking to find how many times 978 goes into 51680441.

Step 1:
978 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 978

Let's proceed to step 2:
978 goes into 51 0 times with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Bring next digit (6) of the dividend behind the 51 and repeat the process: 516 / 978

Step 3:
978 can be fit into 516 0 times, resulting in a remainder of 516.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 516, we get 516.
Fetch the next digit (8) from the dividend, attach it to 516 and continue: 5168 / 978

Moving on to step 4:
978 can be fit into 5168 5 times, resulting in a remainder of 278.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 278 after subtracting 4890 from 5168.
Take the next digit (0) from the dividend and append it to 278, then repeat: 2780 / 978

Advancing to step 5:
978 can be fit into 2780 2 times, resulting in a remainder of 824.
Put 2 as the next digit of the answer. 
Result so far: 52.0
If we subtract 1956 from 2780, we get 824.
Fetch the next digit (4) from the dividend, attach it to 824 and continue: 8244 / 978

Going ahead to step 6:
If we divide 8244 by 978, we get 8 and a remainder of 420.
The next digit of our result is 8. 
Result so far: 528.0
Deduct 7824 from 8244 and we're left with 420.
Append the next digit (4) from the dividend to 420 and continue with: 4204 / 978

Let's proceed to step 7:
When dividing 4204 by 978, we get 4 with a remainder of 292.
Use 4 as the next digit of our solution. 
Result so far: 5284.0
If we take 3912 away from 4204, we end up with 292.
Take the next digit (1) from the dividend and append it to 292, then repeat: 2921 / 978

Moving on to step 8:
978 goes into 2921 2 times with a remainder of 965.
Put 2 as the next digit of the answer. 
Result so far: 52842.0
The remainder is 965 after subtracting 1956 from 2921.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9650, and continue the process.

Step 9:
The number 978 fits into 9650 9 times, leaving a remainder of 848.
The number 9 becomes the next digit in our result. 
Result so far: 52842.9
Subtract 8802 from 9650 to get 848.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8480, and continue the process.

Going ahead to step 10:
978 can be fit into 8480 8 times, resulting in a remainder of 656.
The next digit of our result is 8. 
Result so far: 52842.98
If we subtract 7824 from 8480, we get 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Moving on to step 11:
If we divide 6560 by 978, we get 6 and a remainder of 692.
The number 6 becomes the next digit in our result. 
Result so far: 52842.986
If we take 5868 away from 6560, we end up with 692.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

Step 12:
978 can be fit into 6920 7 times, resulting in a remainder of 74.
The number 7 becomes the next digit in our result. 
Result so far: 52842.9867
Subtracting 6846 from 6920 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 13:
978 goes into 740 0 times with a remainder of 740.
Record the quotient 0 as the next digit in the result. 
Result so far: 52842.9867
If we take 0 away from 740, we end up with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Let's proceed to step 14:
If we divide 7400 by 978, we get 7 and a remainder of 554.
The next digit of our result is 7. 
Result so far: 52842.986707
Subtract 6846 from 7400 to get 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Step 15:
5540 divided by 978 is 5 with a remainder of 650.
The next digit of our result is 5. 
Result so far: 52842.9867075
If we take 4890 away from 5540, we end up with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Let's proceed to step 16:
If we divide 6500 by 978, we get 6 and a remainder of 632.
Put 6 as the next digit of the answer. 
Result so far: 52842.98670756
If we take 5868 away from 6500, we end up with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

In conclusion, the division gives 52842.98670756 with a balance of 6.32e-07.
