21359102 ÷ 131 
Let's see how many times 131 fits into 21359102.

Step 1:
2 divided by 131 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 131

On to step 2:
The number 131 fits into 21 0 times, leaving a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 131

Step 3:
131 goes into 213 1 times with a remainder of 82.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 131 from 213 leaves us with 82.
Take the next digit (5) from the dividend and append it to 82, then repeat: 825 / 131

Let's proceed to step 4:
131 goes into 825 6 times with a remainder of 39.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 786 away from 825, we end up with 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 131

On to step 5:
If we divide 399 by 131, we get 3 and a remainder of 6.
The next digit of our result is 3. 
Result so far: 163.0
Subtract 393 from 399 to get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 131

On to step 6:
The number 131 fits into 61 0 times, leaving a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 1630.0
Deduct 0 from 61 and we're left with 61.
Grab the next digit (0) from the dividend, add it to 61, then carry on: 610 / 131

Step 7:
When dividing 610 by 131, we get 4 with a remainder of 86.
The next digit of our result is 4. 
Result so far: 16304.0
Subtracting 524 from 610 leaves us with 86.
Bring next digit (2) of the dividend behind the 86 and repeat the process: 862 / 131

Going ahead to step 8:
131 goes into 862 6 times with a remainder of 76.
Write down 6 as next digit of the result. 
Result so far: 163046.0
If we subtract 786 from 862, we get 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 9:
When dividing 760 by 131, we get 5 with a remainder of 105.
Use 5 as the next digit of our solution. 
Result so far: 163046.5
The remainder is 105 after subtracting 655 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 10:
131 can be fit into 1050 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 163046.58
The remainder is 2 after subtracting 1048 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
20 divided by 131 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 163046.58
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
The number 131 fits into 200 1 times, leaving a remainder of 69.
Put 1 as the next digit of the answer. 
Result so far: 163046.5801
The remainder is 69 after subtracting 131 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 13:
690 divided by 131 is 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 163046.58015
Deduct 655 from 690 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 14:
131 goes into 350 2 times with a remainder of 88.
Record the quotient 2 as the next digit in the result. 
Result so far: 163046.580152
Subtracting 262 from 350 leaves us with 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 15:
880 divided by 131 is 6 with a remainder of 94.
The number 6 becomes the next digit in our result. 
Result so far: 163046.5801526
If we subtract 786 from 880, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 16:
940 divided by 131 is 7 with a remainder of 23.
The next digit of our result is 7. 
Result so far: 163046.58015267
Subtract 917 from 940 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final outcome is 163046.58015267, with a leftover of 2.3e-08.
