66106725 divided by 978 
We want to figure out the number of times 66106725 can be divided by 978.

Step 1:
If we divide 6 by 978, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 978

Going ahead to step 2:
66 divided by 978 is 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Append the next digit (1) from the dividend to 66 and continue with: 661 / 978

Let's proceed to step 3:
When dividing 661 by 978, we get 0 with a remainder of 661.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 661, we get 661.
Bring next digit (0) of the dividend behind the 661 and repeat the process: 6610 / 978

Advancing to step 4:
6610 divided by 978 is 6 with a remainder of 742.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 742 after subtracting 5868 from 6610.
Take the next digit (6) from the dividend and append it to 742, then repeat: 7426 / 978

Moving on to step 5:
978 goes into 7426 7 times with a remainder of 580.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
Subtract 6846 from 7426 to get 580.
Take the next digit (7) from the dividend and append it to 580, then repeat: 5807 / 978

Step 6:
If we divide 5807 by 978, we get 5 and a remainder of 917.
The next digit of our result is 5. 
Result so far: 675.0
Deduct 4890 from 5807 and we're left with 917.
Take the next digit (2) from the dividend and append it to 917, then repeat: 9172 / 978

Let's proceed to step 7:
If we divide 9172 by 978, we get 9 and a remainder of 370.
The next digit of our result is 9. 
Result so far: 6759.0
The remainder is 370 after subtracting 8802 from 9172.
Include the next digit (5) from the dividend after 370, then repeat: 3705 / 978

Advancing to step 8:
978 goes into 3705 3 times with a remainder of 771.
Use 3 as the next digit of our solution. 
Result so far: 67593.0
Subtract 2934 from 3705 to get 771.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7710, and continue the process.

On to step 9:
The number 978 fits into 7710 7 times, leaving a remainder of 864.
Write down 7 as next digit of the result. 
Result so far: 67593.7
Deduct 6846 from 7710 and we're left with 864.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8640, and continue the process.

On to step 10:
When dividing 8640 by 978, we get 8 with a remainder of 816.
Use 8 as the next digit of our solution. 
Result so far: 67593.78
If we take 7824 away from 8640, we end up with 816.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

Step 11:
978 goes into 8160 8 times with a remainder of 336.
Write down 8 as next digit of the result. 
Result so far: 67593.788
Subtracting 7824 from 8160 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

The final outcome is 67593.788, with a leftover of 0.0336.
