66839905 divided by 195 
We want to divide 66839905 by 195.

Advancing to step 1:
When dividing 6 by 195, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 195

Step 2:
If we divide 66 by 195, we get 0 and 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.
Take the next digit (8) from the dividend and append it to 66, then repeat: 668 / 195

Step 3:
If we divide 668 by 195, we get 3 and a remainder of 83.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 83 after subtracting 585 from 668.
Fetch the next digit (3) from the dividend, attach it to 83 and continue: 833 / 195

Going ahead to step 4:
195 can be fit into 833 4 times, resulting in a remainder of 53.
Put 4 as the next digit of the answer. 
Result so far: 34.0
Subtracting 780 from 833 leaves us with 53.
Include the next digit (9) from the dividend after 53, then repeat: 539 / 195

On to step 5:
When dividing 539 by 195, we get 2 with a remainder of 149.
The next digit of our result is 2. 
Result so far: 342.0
Subtracting 390 from 539 leaves us with 149.
Include the next digit (9) from the dividend after 149, then repeat: 1499 / 195

Going ahead to step 6:
When dividing 1499 by 195, we get 7 with a remainder of 134.
Write down 7 as next digit of the result. 
Result so far: 3427.0
Subtracting 1365 from 1499 leaves us with 134.
Append the next digit (0) from the dividend to 134 and continue with: 1340 / 195

Advancing to step 7:
1340 divided by 195 is 6 with a remainder of 170.
Put 6 as the next digit of the answer. 
Result so far: 34276.0
If we subtract 1170 from 1340, we get 170.
Bring next digit (5) of the dividend behind the 170 and repeat the process: 1705 / 195

Step 8:
When dividing 1705 by 195, we get 8 with a remainder of 145.
Put 8 as the next digit of the answer. 
Result so far: 342768.0
The remainder is 145 after subtracting 1560 from 1705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 9:
1450 divided by 195 is 7 with a remainder of 85.
The number 7 becomes the next digit in our result. 
Result so far: 342768.7
Subtract 1365 from 1450 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 10:
195 can be fit into 850 4 times, resulting in a remainder of 70.
Use 4 as the next digit of our solution. 
Result so far: 342768.74
Subtract 780 from 850 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 11:
195 can be fit into 700 3 times, resulting in a remainder of 115.
Put 3 as the next digit of the answer. 
Result so far: 342768.743
Deduct 585 from 700 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 12:
195 can be fit into 1150 5 times, resulting in a remainder of 175.
The next digit of our result is 5. 
Result so far: 342768.7435
The remainder is 175 after subtracting 975 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 13:
1750 divided by 195 is 8 with a remainder of 190.
Write down 8 as next digit of the result. 
Result so far: 342768.74358
Subtract 1560 from 1750 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 14:
195 can be fit into 1900 9 times, resulting in a remainder of 145.
Put 9 as the next digit of the answer. 
Result so far: 342768.743589
If we take 1755 away from 1900, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 15:
195 goes into 1450 7 times with a remainder of 85.
Record the quotient 7 as the next digit in the result. 
Result so far: 342768.7435897
Deduct 1365 from 1450 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 16:
850 divided by 195 is 4 with a remainder of 70.
Record the quotient 4 as the next digit in the result. 
Result so far: 342768.74358974
Subtract 780 from 850 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

In conclusion, the division gives 342768.74358974 with a balance of 7e-08.
