We divide 22180989 by 644
We're looking to find how many times 644 goes into 22180989.

Advancing to step 1:
644 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 644

Step 2:
If we divide 22 by 644, we get 0 and a remainder of 22.
Use 0 as the next digit of our solution. 
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

Let's proceed to step 3:
The number 644 fits into 221 0 times, leaving a remainder of 221.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 221, we end up with 221.
Grab the next digit (8) from the dividend, add it to 221, then carry on: 2218 / 644

Step 4:
If we divide 2218 by 644, we get 3 and a remainder of 286.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 1932 from 2218 to get 286.
Take the next digit (0) from the dividend and append it to 286, then repeat: 2860 / 644

Moving on to step 5:
644 can be fit into 2860 4 times, resulting in a remainder of 284.
Put 4 as the next digit of the answer. 
Result so far: 34.0
The remainder is 284 after subtracting 2576 from 2860.
Include the next digit (9) from the dividend after 284, then repeat: 2849 / 644

Advancing to step 6:
When dividing 2849 by 644, we get 4 with a remainder of 273.
The next digit of our result is 4. 
Result so far: 344.0
If we subtract 2576 from 2849, we get 273.
Append the next digit (8) from the dividend to 273 and continue with: 2738 / 644

On to step 7:
2738 divided by 644 is 4 with a remainder of 162.
Write down 4 as next digit of the result. 
Result so far: 3444.0
If we take 2576 away from 2738, we end up with 162.
Fetch the next digit (9) from the dividend, attach it to 162 and continue: 1629 / 644

Let's proceed to step 8:
644 goes into 1629 2 times with a remainder of 341.
Write down 2 as next digit of the result. 
Result so far: 34442.0
Subtracting 1288 from 1629 leaves us with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Let's proceed to step 9:
When dividing 3410 by 644, we get 5 with a remainder of 190.
The number 5 becomes the next digit in our result. 
Result so far: 34442.5
If we take 3220 away from 3410, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 10:
1900 divided by 644 is 2 with a remainder of 612.
Put 2 as the next digit of the answer. 
Result so far: 34442.52
Deduct 1288 from 1900 and we're left with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Moving on to step 11:
6120 divided by 644 is 9 with a remainder of 324.
Put 9 as the next digit of the answer. 
Result so far: 34442.529
Deduct 5796 from 6120 and we're left with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

On to step 12:
644 can be fit into 3240 5 times, resulting in a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 34442.5295
If we subtract 3220 from 3240, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
644 goes into 200 0 times with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 34442.5295
If we take 0 away from 200, 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.

Moving on to step 14:
644 goes into 2000 3 times with a remainder of 68.
Record the quotient 3 as the next digit in the result. 
Result so far: 34442.529503
The remainder is 68 after subtracting 1932 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 15:
680 divided by 644 is 1 with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 34442.5295031
Subtract 644 from 680 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 16:
644 goes into 360 0 times with a remainder of 360.
Record the quotient 0 as the next digit in the result. 
Result so far: 34442.5295031
If we take 0 away from 360, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

The quotient of the division is 34442.5295031, and the remainder is 3.6e-07.
