We're dividing 66185704 by 259 
Our goal is to divide 66185704 by 259.

Advancing to step 1:
If we divide 6 by 259, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 259

On to step 2:
When dividing 66 by 259, we get 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Fetch the next digit (1) from the dividend, attach it to 66 and continue: 661 / 259

Going ahead to step 3:
661 divided by 259 is 2 with a remainder of 143.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 143 after subtracting 518 from 661.
Include the next digit (8) from the dividend after 143, then repeat: 1438 / 259

Step 4:
259 goes into 1438 5 times with a remainder of 143.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtract 1295 from 1438 to get 143.
Append the next digit (5) from the dividend to 143 and continue with: 1435 / 259

Moving on to step 5:
259 can be fit into 1435 5 times, resulting in a remainder of 140.
Use 5 as the next digit of our solution. 
Result so far: 255.0
Subtract 1295 from 1435 to get 140.
Take the next digit (7) from the dividend and append it to 140, then repeat: 1407 / 259

Going ahead to step 6:
When dividing 1407 by 259, we get 5 with a remainder of 112.
Put 5 as the next digit of the answer. 
Result so far: 2555.0
The remainder is 112 after subtracting 1295 from 1407.
Grab the next digit (0) from the dividend, add it to 112, then carry on: 1120 / 259

On to step 7:
When dividing 1120 by 259, we get 4 with a remainder of 84.
The next digit of our result is 4. 
Result so far: 25554.0
If we take 1036 away from 1120, we end up with 84.
Fetch the next digit (4) from the dividend, attach it to 84 and continue: 844 / 259

Step 8:
When dividing 844 by 259, we get 3 with a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 255543.0
If we take 777 away from 844, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 9:
670 divided by 259 is 2 with a remainder of 152.
Record the quotient 2 as the next digit in the result. 
Result so far: 255543.2
If we take 518 away from 670, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 10:
259 goes into 1520 5 times with a remainder of 225.
Put 5 as the next digit of the answer. 
Result so far: 255543.25
Deduct 1295 from 1520 and we're left with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Advancing to step 11:
If we divide 2250 by 259, we get 8 and a remainder of 178.
Record the quotient 8 as the next digit in the result. 
Result so far: 255543.258
Subtract 2072 from 2250 to get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

On to step 12:
259 can be fit into 1780 6 times, resulting in a remainder of 226.
Use 6 as the next digit of our solution. 
Result so far: 255543.2586
If we take 1554 away from 1780, we end up with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Let's proceed to step 13:
The number 259 fits into 2260 8 times, leaving a remainder of 188.
The number 8 becomes the next digit in our result. 
Result so far: 255543.25868
Deduct 2072 from 2260 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Step 14:
259 can be fit into 1880 7 times, resulting in a remainder of 67.
The next digit of our result is 7. 
Result so far: 255543.258687
If we take 1813 away from 1880, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 15:
The number 259 fits into 670 2 times, leaving a remainder of 152.
Write down 2 as next digit of the result. 
Result so far: 255543.2586872
If we subtract 518 from 670, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 16:
1520 divided by 259 is 5 with a remainder of 225.
The next digit of our result is 5. 
Result so far: 255543.25868725
If we subtract 1295 from 1520, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

The final result is 255543.25868725 with a remainder of 2.25e-07.
