We're dividing 21115029 by 344 
Our goal is to divide 21115029 by 344.

Let's proceed to step 1:
If we divide 2 by 344, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 344

Let's proceed to step 2:
21 divided by 344 is 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 344

Advancing to step 3:
When dividing 211 by 344, we get 0 with a remainder of 211.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 211 to get 211.
Bring next digit (1) of the dividend behind the 211 and repeat the process: 2111 / 344

Let's proceed to step 4:
344 can be fit into 2111 6 times, resulting in a remainder of 47.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 2064 from 2111 to get 47.
Take the next digit (5) from the dividend and append it to 47, then repeat: 475 / 344

On to step 5:
If we divide 475 by 344, we get 1 and a remainder of 131.
The next digit of our result is 1. 
Result so far: 61.0
Subtracting 344 from 475 leaves us with 131.
Grab the next digit (0) from the dividend, add it to 131, then carry on: 1310 / 344

Step 6:
If we divide 1310 by 344, we get 3 and a remainder of 278.
Write down 3 as next digit of the result. 
Result so far: 613.0
If we subtract 1032 from 1310, we get 278.
Take the next digit (2) from the dividend and append it to 278, then repeat: 2782 / 344

Going ahead to step 7:
When dividing 2782 by 344, we get 8 with a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 6138.0
If we subtract 2752 from 2782, we get 30.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 344

Moving on to step 8:
309 divided by 344 is 0 with a remainder of 309.
Put 0 as the next digit of the answer. 
Result so far: 61380.0
The remainder is 309 after subtracting 0 from 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Step 9:
If we divide 3090 by 344, we get 8 and a remainder of 338.
Use 8 as the next digit of our solution. 
Result so far: 61380.8
Subtract 2752 from 3090 to get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Advancing to step 10:
3380 divided by 344 is 9 with a remainder of 284.
The number 9 becomes the next digit in our result. 
Result so far: 61380.89
If we take 3096 away from 3380, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Step 11:
2840 divided by 344 is 8 with a remainder of 88.
The next digit of our result is 8. 
Result so far: 61380.898
If we subtract 2752 from 2840, we 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.

Going ahead to step 12:
880 divided by 344 is 2 with a remainder of 192.
The next digit of our result is 2. 
Result so far: 61380.8982
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.

Advancing to step 13:
The number 344 fits into 1920 5 times, leaving a remainder of 200.
Write down 5 as next digit of the result. 
Result so far: 61380.89825
If we take 1720 away from 1920, we end up 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.

On to step 14:
If we divide 2000 by 344, we get 5 and a remainder of 280.
Write down 5 as next digit of the result. 
Result so far: 61380.898255
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.

After the division, we end up with 61380.898255 and a remainder of 2.8e-05.
