21265496 ÷ 344 
We want to figure out the number of times 21265496 can be divided by 344.

Advancing to step 1:
If we divide 2 by 344, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 344

Moving on to step 2:
When dividing 21 by 344, we get 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 344

Moving on to step 3:
212 divided by 344 is 0 with a remainder of 212.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 212 after subtracting 0 from 212.
Include the next digit (6) from the dividend after 212, then repeat: 2126 / 344

Moving on to step 4:
When dividing 2126 by 344, we get 6 with a remainder of 62.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 62 after subtracting 2064 from 2126.
Bring next digit (5) of the dividend behind the 62 and repeat the process: 625 / 344

Advancing to step 5:
344 goes into 625 1 times with a remainder of 281.
The next digit of our result is 1. 
Result so far: 61.0
The remainder is 281 after subtracting 344 from 625.
Take the next digit (4) from the dividend and append it to 281, then repeat: 2814 / 344

Moving on to step 6:
If we divide 2814 by 344, we get 8 and a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 618.0
If we subtract 2752 from 2814, we get 62.
Append the next digit (9) from the dividend to 62 and continue with: 629 / 344

Advancing to step 7:
344 goes into 629 1 times with a remainder of 285.
Put 1 as the next digit of the answer. 
Result so far: 6181.0
Subtract 344 from 629 to get 285.
Fetch the next digit (6) from the dividend, attach it to 285 and continue: 2856 / 344

On to step 8:
344 goes into 2856 8 times with a remainder of 104.
Record the quotient 8 as the next digit in the result. 
Result so far: 61818.0
Deduct 2752 from 2856 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 9:
1040 divided by 344 is 3 with a remainder of 8.
The next digit of our result is 3. 
Result so far: 61818.3
Subtracting 1032 from 1040 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
If we divide 80 by 344, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 61818.3
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 11:
344 can be fit into 800 2 times, resulting in a remainder of 112.
Use 2 as the next digit of our solution. 
Result so far: 61818.302
Deduct 688 from 800 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 12:
If we divide 1120 by 344, we get 3 and a remainder of 88.
The number 3 becomes the next digit in our result. 
Result so far: 61818.3023
Deduct 1032 from 1120 and we're left 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.

Advancing to step 13:
When dividing 880 by 344, we get 2 with a remainder of 192.
The next digit of our result is 2. 
Result so far: 61818.30232
If we take 688 away from 880, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 14:
1920 divided by 344 is 5 with a remainder of 200.
The next digit of our result is 5. 
Result so far: 61818.302325
Subtracting 1720 from 1920 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 15:
344 goes into 2000 5 times with a remainder of 280.
The number 5 becomes the next digit in our result. 
Result so far: 61818.3023255
Deduct 1720 from 2000 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final outcome is 61818.3023255, with a leftover of 2.8e-06.
