We're dividing 66360259 by 261 
Let's see how many times 261 fits into 66360259.

Going ahead to step 1:
If we divide 6 by 261, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 261

Moving on to step 2:
When dividing 66 by 261, we get 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Include the next digit (3) from the dividend after 66, then repeat: 663 / 261

Moving on to step 3:
When dividing 663 by 261, we get 2 with a remainder of 141.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 522 from 663 leaves us with 141.
Take the next digit (6) from the dividend and append it to 141, then repeat: 1416 / 261

Step 4:
1416 divided by 261 is 5 with a remainder of 111.
Write down 5 as next digit of the result. 
Result so far: 25.0
If we subtract 1305 from 1416, we get 111.
Take the next digit (0) from the dividend and append it to 111, then repeat: 1110 / 261

On to step 5:
If we divide 1110 by 261, we get 4 and a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 254.0
The remainder is 66 after subtracting 1044 from 1110.
Include the next digit (2) from the dividend after 66, then repeat: 662 / 261

Let's proceed to step 6:
The number 261 fits into 662 2 times, leaving a remainder of 140.
Write down 2 as next digit of the result. 
Result so far: 2542.0
Subtracting 522 from 662 leaves us with 140.
Include the next digit (5) from the dividend after 140, then repeat: 1405 / 261

Advancing to step 7:
When dividing 1405 by 261, we get 5 with a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 25425.0
Subtract 1305 from 1405 to get 100.
Take the next digit (9) from the dividend and append it to 100, then repeat: 1009 / 261

On to step 8:
The number 261 fits into 1009 3 times, leaving a remainder of 226.
The next digit of our result is 3. 
Result so far: 254253.0
If we take 783 away from 1009, 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.

Advancing to step 9:
When dividing 2260 by 261, we get 8 with a remainder of 172.
Put 8 as the next digit of the answer. 
Result so far: 254253.8
The remainder is 172 after subtracting 2088 from 2260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 10:
261 can be fit into 1720 6 times, resulting in a remainder of 154.
Write down 6 as next digit of the result. 
Result so far: 254253.86
Subtract 1566 from 1720 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Going ahead to step 11:
When dividing 1540 by 261, we get 5 with a remainder of 235.
Record the quotient 5 as the next digit in the result. 
Result so far: 254253.865
If we subtract 1305 from 1540, we get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

On to step 12:
261 goes into 2350 9 times with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 254253.8659
If we take 2349 away from 2350, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 13:
10 divided by 261 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 254253.8659
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
261 can be fit into 100 0 times, resulting in a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 254253.8659
Deduct 0 from 100 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.

Our division results in 254253.8659 with a remaining 1e-05.
