Let's divide 68399075 by 660
We're looking to find how many times 660 goes into 68399075.

Going ahead to step 1:
660 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 660

Let's proceed to step 2:
The number 660 fits into 68 0 times, leaving a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Fetch the next digit (3) from the dividend, attach it to 68 and continue: 683 / 660

Let's proceed to step 3:
660 goes into 683 1 times with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 660 from 683 leaves us with 23.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 660

Let's proceed to step 4:
660 goes into 239 0 times with a remainder of 239.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 239 after subtracting 0 from 239.
Fetch the next digit (9) from the dividend, attach it to 239 and continue: 2399 / 660

Step 5:
The number 660 fits into 2399 3 times, leaving a remainder of 419.
Put 3 as the next digit of the answer. 
Result so far: 103.0
If we take 1980 away from 2399, we end up with 419.
Take the next digit (0) from the dividend and append it to 419, then repeat: 4190 / 660

Step 6:
If we divide 4190 by 660, we get 6 and a remainder of 230.
Use 6 as the next digit of our solution. 
Result so far: 1036.0
The remainder is 230 after subtracting 3960 from 4190.
Bring next digit (7) of the dividend behind the 230 and repeat the process: 2307 / 660

Moving on to step 7:
The number 660 fits into 2307 3 times, leaving a remainder of 327.
Use 3 as the next digit of our solution. 
Result so far: 10363.0
Subtracting 1980 from 2307 leaves us with 327.
Include the next digit (5) from the dividend after 327, then repeat: 3275 / 660

Let's proceed to step 8:
3275 divided by 660 is 4 with a remainder of 635.
Put 4 as the next digit of the answer. 
Result so far: 103634.0
The remainder is 635 after subtracting 2640 from 3275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Let's proceed to step 9:
6350 divided by 660 is 9 with a remainder of 410.
The number 9 becomes the next digit in our result. 
Result so far: 103634.9
Subtracting 5940 from 6350 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 10:
When dividing 4100 by 660, we get 6 with a remainder of 140.
Record the quotient 6 as the next digit in the result. 
Result so far: 103634.96
Subtract 3960 from 4100 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 11:
660 goes into 1400 2 times with a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 103634.962
Deduct 1320 from 1400 and we're left with 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 12:
If we divide 800 by 660, we get 1 and a remainder of 140.
The next digit of our result is 1. 
Result so far: 103634.9621
If we subtract 660 from 800, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 13:
The number 660 fits into 1400 2 times, leaving a remainder of 80.
Put 2 as the next digit of the answer. 
Result so far: 103634.96212
Subtract 1320 from 1400 to 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.

Going ahead to step 14:
660 can be fit into 800 1 times, resulting in a remainder of 140.
Use 1 as the next digit of our solution. 
Result so far: 103634.962121
Subtracting 660 from 800 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 15:
660 can be fit into 1400 2 times, resulting in a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 103634.9621212
Subtracting 1320 from 1400 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 16:
The number 660 fits into 800 1 times, leaving a remainder of 140.
The next digit of our result is 1. 
Result so far: 103634.96212121
Subtract 660 from 800 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final outcome is 103634.96212121, with a leftover of 1.4e-07.
