66805694 ÷ 259 
Let's see how many times 259 fits into 66805694.

Going ahead to step 1:
When dividing 6 by 259, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 259

Step 2:
66 divided by 259 is 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Grab the next digit (8) from the dividend, add it to 66, then carry on: 668 / 259

On to step 3:
668 divided by 259 is 2 with a remainder of 150.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 518 from 668 and we're left with 150.
Take the next digit (0) from the dividend and append it to 150, then repeat: 1500 / 259

Step 4:
If we divide 1500 by 259, we get 5 and a remainder of 205.
Write down 5 as next digit of the result. 
Result so far: 25.0
If we take 1295 away from 1500, we end up with 205.
Grab the next digit (5) from the dividend, add it to 205, then carry on: 2055 / 259

Going ahead to step 5:
When dividing 2055 by 259, we get 7 with a remainder of 242.
Write down 7 as next digit of the result. 
Result so far: 257.0
Deduct 1813 from 2055 and we're left with 242.
Fetch the next digit (6) from the dividend, attach it to 242 and continue: 2426 / 259

Step 6:
If we divide 2426 by 259, we get 9 and a remainder of 95.
Write down 9 as next digit of the result. 
Result so far: 2579.0
If we take 2331 away from 2426, we end up with 95.
Include the next digit (9) from the dividend after 95, then repeat: 959 / 259

Advancing to step 7:
If we divide 959 by 259, we get 3 and a remainder of 182.
The number 3 becomes the next digit in our result. 
Result so far: 25793.0
Subtracting 777 from 959 leaves us with 182.
Fetch the next digit (4) from the dividend, attach it to 182 and continue: 1824 / 259

Step 8:
1824 divided by 259 is 7 with a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 257937.0
If we take 1813 away from 1824, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 9:
110 divided by 259 is 0 with a remainder of 110.
Put 0 as the next digit of the answer. 
Result so far: 257937.0
The remainder is 110 after subtracting 0 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 10:
259 goes into 1100 4 times with a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 257937.04
If we subtract 1036 from 1100, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 11:
When dividing 640 by 259, we get 2 with a remainder of 122.
Put 2 as the next digit of the answer. 
Result so far: 257937.042
Subtracting 518 from 640 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Going ahead to step 12:
When dividing 1220 by 259, we get 4 with a remainder of 184.
The next digit of our result is 4. 
Result so far: 257937.0424
Subtract 1036 from 1220 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 13:
If we divide 1840 by 259, we get 7 and a remainder of 27.
The next digit of our result is 7. 
Result so far: 257937.04247
Deduct 1813 from 1840 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 14:
259 goes into 270 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 257937.042471
The remainder is 11 after subtracting 259 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 15:
110 divided by 259 is 0 with a remainder of 110.
Record the quotient 0 as the next digit in the result. 
Result so far: 257937.042471
Deduct 0 from 110 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 16:
The number 259 fits into 1100 4 times, leaving a remainder of 64.
The next digit of our result is 4. 
Result so far: 257937.04247104
Deduct 1036 from 1100 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

In conclusion, the division gives 257937.04247104 with a balance of 6.4e-08.
