We look at the division of 66454247 by 978 
Let's see how many times 978 fits into 66454247.

Step 1:
978 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 978

Step 2:
66 divided by 978 is 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Bring next digit (4) of the dividend behind the 66 and repeat the process: 664 / 978

Let's proceed to step 3:
978 goes into 664 0 times with a remainder of 664.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 664, we end up with 664.
Take the next digit (5) from the dividend and append it to 664, then repeat: 6645 / 978

Moving on to step 4:
If we divide 6645 by 978, we get 6 and a remainder of 777.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 5868 from 6645 to get 777.
Fetch the next digit (4) from the dividend, attach it to 777 and continue: 7774 / 978

Step 5:
The number 978 fits into 7774 7 times, leaving a remainder of 928.
Use 7 as the next digit of our solution. 
Result so far: 67.0
Subtract 6846 from 7774 to get 928.
Bring next digit (2) of the dividend behind the 928 and repeat the process: 9282 / 978

Let's proceed to step 6:
978 goes into 9282 9 times with a remainder of 480.
Write down 9 as next digit of the result. 
Result so far: 679.0
If we subtract 8802 from 9282, we get 480.
Fetch the next digit (4) from the dividend, attach it to 480 and continue: 4804 / 978

Advancing to step 7:
If we divide 4804 by 978, we get 4 and a remainder of 892.
Use 4 as the next digit of our solution. 
Result so far: 6794.0
Subtracting 3912 from 4804 leaves us with 892.
Include the next digit (7) from the dividend after 892, then repeat: 8927 / 978

Going ahead to step 8:
The number 978 fits into 8927 9 times, leaving a remainder of 125.
Use 9 as the next digit of our solution. 
Result so far: 67949.0
Subtracting 8802 from 8927 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 9:
When dividing 1250 by 978, we get 1 with a remainder of 272.
Record the quotient 1 as the next digit in the result. 
Result so far: 67949.1
If we subtract 978 from 1250, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 10:
If we divide 2720 by 978, we get 2 and a remainder of 764.
The next digit of our result is 2. 
Result so far: 67949.12
Subtracting 1956 from 2720 leaves us with 764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

Going ahead to step 11:
When dividing 7640 by 978, we get 7 with a remainder of 794.
Put 7 as the next digit of the answer. 
Result so far: 67949.127
Deduct 6846 from 7640 and we're left with 794.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

Step 12:
7940 divided by 978 is 8 with a remainder of 116.
Use 8 as the next digit of our solution. 
Result so far: 67949.1278
If we take 7824 away from 7940, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 13:
978 can be fit into 1160 1 times, resulting in a remainder of 182.
Use 1 as the next digit of our solution. 
Result so far: 67949.12781
Subtract 978 from 1160 to get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Advancing to step 14:
1820 divided by 978 is 1 with a remainder of 842.
The number 1 becomes the next digit in our result. 
Result so far: 67949.127811
If we take 978 away from 1820, we end up with 842.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8420, and continue the process.

In conclusion, the division gives 67949.127811 with a balance of 8.42e-05.
