We're dividing 21869829 by 263 
We're looking to find how many times 263 goes into 21869829.

Let's proceed to step 1:
The number 263 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 263

Let's proceed to step 2:
The number 263 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 263

Moving on to step 3:
218 divided by 263 is 0 with a remainder of 218.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 218, we get 218.
Include the next digit (6) from the dividend after 218, then repeat: 2186 / 263

Step 4:
263 can be fit into 2186 8 times, resulting in a remainder of 82.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 82 after subtracting 2104 from 2186.
Grab the next digit (9) from the dividend, add it to 82, then carry on: 829 / 263

Advancing to step 5:
263 can be fit into 829 3 times, resulting in a remainder of 40.
The next digit of our result is 3. 
Result so far: 83.0
Deduct 789 from 829 and we're left with 40.
Grab the next digit (8) from the dividend, add it to 40, then carry on: 408 / 263

Going ahead to step 6:
The number 263 fits into 408 1 times, leaving a remainder of 145.
Write down 1 as next digit of the result. 
Result so far: 831.0
Deduct 263 from 408 and we're left with 145.
Grab the next digit (2) from the dividend, add it to 145, then carry on: 1452 / 263

Moving on to step 7:
263 can be fit into 1452 5 times, resulting in a remainder of 137.
Record the quotient 5 as the next digit in the result. 
Result so far: 8315.0
If we subtract 1315 from 1452, we get 137.
Fetch the next digit (9) from the dividend, attach it to 137 and continue: 1379 / 263

Going ahead to step 8:
263 can be fit into 1379 5 times, resulting in a remainder of 64.
Write down 5 as next digit of the result. 
Result so far: 83155.0
If we take 1315 away from 1379, we end up 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.

Advancing to step 9:
263 goes into 640 2 times with a remainder of 114.
The number 2 becomes the next digit in our result. 
Result so far: 83155.2
Deduct 526 from 640 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Going ahead to step 10:
263 goes into 1140 4 times with a remainder of 88.
The next digit of our result is 4. 
Result so far: 83155.24
Subtract 1052 from 1140 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 11:
880 divided by 263 is 3 with a remainder of 91.
Use 3 as the next digit of our solution. 
Result so far: 83155.243
The remainder is 91 after subtracting 789 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Moving on to step 12:
910 divided by 263 is 3 with a remainder of 121.
Use 3 as the next digit of our solution. 
Result so far: 83155.2433
Subtracting 789 from 910 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

After the division, we end up with 83155.2433 and a remainder of 0.00121.
