21884013 divided by 426 
We want to figure out the number of times 21884013 can be divided by 426.

Advancing to step 1:
When dividing 2 by 426, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 426

Let's proceed to step 2:
The number 426 fits into 21 0 times, leaving a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 426

On to step 3:
The number 426 fits into 218 0 times, leaving a remainder of 218.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 218 and we're left with 218.
Bring next digit (8) of the dividend behind the 218 and repeat the process: 2188 / 426

Let's proceed to step 4:
426 can be fit into 2188 5 times, resulting in a remainder of 58.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 2130 from 2188 to get 58.
Take the next digit (4) from the dividend and append it to 58, then repeat: 584 / 426

Moving on to step 5:
426 goes into 584 1 times with a remainder of 158.
Use 1 as the next digit of our solution. 
Result so far: 51.0
Subtracting 426 from 584 leaves us with 158.
Grab the next digit (0) from the dividend, add it to 158, then carry on: 1580 / 426

Going ahead to step 6:
If we divide 1580 by 426, we get 3 and a remainder of 302.
Write down 3 as next digit of the result. 
Result so far: 513.0
If we subtract 1278 from 1580, we get 302.
Take the next digit (1) from the dividend and append it to 302, then repeat: 3021 / 426

Let's proceed to step 7:
The number 426 fits into 3021 7 times, leaving a remainder of 39.
The next digit of our result is 7. 
Result so far: 5137.0
If we take 2982 away from 3021, we end up with 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 426

Let's proceed to step 8:
393 divided by 426 is 0 with a remainder of 393.
Put 0 as the next digit of the answer. 
Result so far: 51370.0
If we take 0 away from 393, we end up with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Going ahead to step 9:
3930 divided by 426 is 9 with a remainder of 96.
The number 9 becomes the next digit in our result. 
Result so far: 51370.9
Deduct 3834 from 3930 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 10:
426 can be fit into 960 2 times, resulting in a remainder of 108.
The next digit of our result is 2. 
Result so far: 51370.92
Deduct 852 from 960 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 11:
The number 426 fits into 1080 2 times, leaving a remainder of 228.
The number 2 becomes the next digit in our result. 
Result so far: 51370.922
The remainder is 228 after subtracting 852 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

After the division, we end up with 51370.922 and a remainder of 0.0228.
