We look at the division of 6600658 by 140 
We're looking to find how many times 140 goes into 6600658.

Going ahead to step 1:
6 divided by 140 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 140

Advancing to step 2:
140 goes into 66 0 times with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Append the next digit (0) from the dividend to 66 and continue with: 660 / 140

Going ahead to step 3:
660 divided by 140 is 4 with a remainder of 100.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 560 from 660 and we're left with 100.
Grab the next digit (0) from the dividend, add it to 100, then carry on: 1000 / 140

Going ahead to step 4:
When dividing 1000 by 140, we get 7 with a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
Subtracting 980 from 1000 leaves us with 20.
Take the next digit (6) from the dividend and append it to 20, then repeat: 206 / 140

On to step 5:
The number 140 fits into 206 1 times, leaving a remainder of 66.
The number 1 becomes the next digit in our result. 
Result so far: 471.0
Subtract 140 from 206 to get 66.
Include the next digit (5) from the dividend after 66, then repeat: 665 / 140

Let's proceed to step 6:
If we divide 665 by 140, we get 4 and a remainder of 105.
Write down 4 as next digit of the result. 
Result so far: 4714.0
If we subtract 560 from 665, we get 105.
Grab the next digit (8) from the dividend, add it to 105, then carry on: 1058 / 140

Step 7:
If we divide 1058 by 140, we get 7 and a remainder of 78.
Write down 7 as next digit of the result. 
Result so far: 47147.0
Subtracting 980 from 1058 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 8:
140 goes into 780 5 times with a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 47147.5
If we subtract 700 from 780, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 9:
800 divided by 140 is 5 with a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 47147.55
Deduct 700 from 800 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 47147.55, with a leftover of 0.1.
