66658725 divided by 140 
We want to figure out the number of times 66658725 can be divided by 140.

Let's proceed to step 1:
6 divided by 140 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 140

Moving on to step 2:
140 goes into 66 0 times with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Take the next digit (6) from the dividend and append it to 66, then repeat: 666 / 140

Going ahead to step 3:
666 divided by 140 is 4 with a remainder of 106.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 560 from 666 to get 106.
Include the next digit (5) from the dividend after 106, then repeat: 1065 / 140

Advancing to step 4:
When dividing 1065 by 140, we get 7 with a remainder of 85.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
If we take 980 away from 1065, we end up with 85.
Append the next digit (8) from the dividend to 85 and continue with: 858 / 140

Step 5:
858 divided by 140 is 6 with a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 476.0
If we take 840 away from 858, we end up with 18.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 140

Advancing to step 6:
140 goes into 187 1 times with a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 4761.0
If we subtract 140 from 187, we get 47.
Bring next digit (2) of the dividend behind the 47 and repeat the process: 472 / 140

Moving on to step 7:
The number 140 fits into 472 3 times, leaving a remainder of 52.
Write down 3 as next digit of the result. 
Result so far: 47613.0
Deduct 420 from 472 and we're left with 52.
Grab the next digit (5) from the dividend, add it to 52, then carry on: 525 / 140

Moving on to step 8:
If we divide 525 by 140, we get 3 and a remainder of 105.
Write down 3 as next digit of the result. 
Result so far: 476133.0
The remainder is 105 after subtracting 420 from 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 9:
If we divide 1050 by 140, we get 7 and a remainder of 70.
The next digit of our result is 7. 
Result so far: 476133.7
If we take 980 away from 1050, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
140 can be fit into 700 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 476133.75
Deduct 700 from 700 and we're left 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.

Step 11:
When dividing 0 by 140, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 476133.75
Deduct 0 from 0 and we're left 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.

Going ahead to step 12:
If we divide 0 by 140, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 476133.75
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.

In conclusion, the division gives 476133.75 with a balance of 0.0.
