We're dividing 66181721 by 263 
Let's see how many times 263 fits into 66181721.

On to step 1:
When dividing 6 by 263, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 263

Let's proceed to step 2:
If we divide 66 by 263, we get 0 and a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Fetch the next digit (1) from the dividend, attach it to 66 and continue: 661 / 263

Let's proceed to step 3:
661 divided by 263 is 2 with a remainder of 135.
The next digit of our result is 2. 
Result so far: 2.0
If we take 526 away from 661, we end up with 135.
Include the next digit (8) from the dividend after 135, then repeat: 1358 / 263

Advancing to step 4:
263 goes into 1358 5 times with a remainder of 43.
The next digit of our result is 5. 
Result so far: 25.0
Deduct 1315 from 1358 and we're left with 43.
Append the next digit (1) from the dividend to 43 and continue with: 431 / 263

Let's proceed to step 5:
263 can be fit into 431 1 times, resulting in a remainder of 168.
The next digit of our result is 1. 
Result so far: 251.0
If we subtract 263 from 431, we get 168.
Take the next digit (7) from the dividend and append it to 168, then repeat: 1687 / 263

Let's proceed to step 6:
263 goes into 1687 6 times with a remainder of 109.
The next digit of our result is 6. 
Result so far: 2516.0
The remainder is 109 after subtracting 1578 from 1687.
Grab the next digit (2) from the dividend, add it to 109, then carry on: 1092 / 263

Moving on to step 7:
263 goes into 1092 4 times with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 25164.0
If we take 1052 away from 1092, we end up with 40.
Take the next digit (1) from the dividend and append it to 40, then repeat: 401 / 263

Moving on to step 8:
The number 263 fits into 401 1 times, leaving a remainder of 138.
Use 1 as the next digit of our solution. 
Result so far: 251641.0
If we take 263 away from 401, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 9:
If we divide 1380 by 263, we get 5 and a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 251641.5
If we subtract 1315 from 1380, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 10:
263 goes into 650 2 times with a remainder of 124.
Put 2 as the next digit of the answer. 
Result so far: 251641.52
Subtract 526 from 650 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 11:
If we divide 1240 by 263, we get 4 and a remainder of 188.
The next digit of our result is 4. 
Result so far: 251641.524
Subtract 1052 from 1240 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 12:
1880 divided by 263 is 7 with a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 251641.5247
Subtracting 1841 from 1880 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 13:
If we divide 390 by 263, we get 1 and a remainder of 127.
Put 1 as the next digit of the answer. 
Result so far: 251641.52471
Subtract 263 from 390 to get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Moving on to step 14:
263 goes into 1270 4 times with a remainder of 218.
Write down 4 as next digit of the result. 
Result so far: 251641.524714
Subtract 1052 from 1270 to get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Moving on to step 15:
If we divide 2180 by 263, we get 8 and a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 251641.5247148
If we take 2104 away from 2180, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 16:
If we divide 760 by 263, we get 2 and a remainder of 234.
The next digit of our result is 2. 
Result so far: 251641.52471482
Deduct 526 from 760 and we're left with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

The quotient of the division is 251641.52471482, and the remainder is 2.34e-07.
