Let's divide 22126619 by 644
We're looking to find how many times 644 goes into 22126619.

Advancing to step 1:
644 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 644

On to step 2:
22 divided by 644 is 0 with a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 22, we end up with 22.
Grab the next digit (1) from the dividend, add it to 22, then carry on: 221 / 644

Going ahead to step 3:
If we divide 221 by 644, we get 0 and a remainder of 221.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 221, we end up with 221.
Include the next digit (2) from the dividend after 221, then repeat: 2212 / 644

Step 4:
644 goes into 2212 3 times with a remainder of 280.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 1932 from 2212, we get 280.
Fetch the next digit (6) from the dividend, attach it to 280 and continue: 2806 / 644

Moving on to step 5:
644 goes into 2806 4 times with a remainder of 230.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
If we take 2576 away from 2806, we end up with 230.
Include the next digit (6) from the dividend after 230, then repeat: 2306 / 644

On to step 6:
When dividing 2306 by 644, we get 3 with a remainder of 374.
Put 3 as the next digit of the answer. 
Result so far: 343.0
If we take 1932 away from 2306, we end up with 374.
Append the next digit (1) from the dividend to 374 and continue with: 3741 / 644

Advancing to step 7:
644 can be fit into 3741 5 times, resulting in a remainder of 521.
Record the quotient 5 as the next digit in the result. 
Result so far: 3435.0
Subtract 3220 from 3741 to get 521.
Include the next digit (9) from the dividend after 521, then repeat: 5219 / 644

Step 8:
When dividing 5219 by 644, we get 8 with a remainder of 67.
Put 8 as the next digit of the answer. 
Result so far: 34358.0
If we take 5152 away from 5219, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 9:
The number 644 fits into 670 1 times, leaving a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 34358.1
Deduct 644 from 670 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 10:
The number 644 fits into 260 0 times, leaving a remainder of 260.
Write down 0 as next digit of the result. 
Result so far: 34358.1
If we take 0 away from 260, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 11:
When dividing 2600 by 644, we get 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 34358.104
Subtract 2576 from 2600 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 12:
644 goes into 240 0 times with a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 34358.104
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 13:
644 goes into 2400 3 times with a remainder of 468.
Put 3 as the next digit of the answer. 
Result so far: 34358.10403
The remainder is 468 after subtracting 1932 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Advancing to step 14:
644 goes into 4680 7 times with a remainder of 172.
Put 7 as the next digit of the answer. 
Result so far: 34358.104037
Subtract 4508 from 4680 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 15:
If we divide 1720 by 644, we get 2 and a remainder of 432.
Use 2 as the next digit of our solution. 
Result so far: 34358.1040372
If we subtract 1288 from 1720, we get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

On to step 16:
The number 644 fits into 4320 6 times, leaving a remainder of 456.
The next digit of our result is 6. 
Result so far: 34358.10403726
Subtract 3864 from 4320 to get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

The final outcome is 34358.10403726, with a leftover of 4.56e-07.
