Let's divide 28922783 by 644
We want to figure out the number of times 28922783 can be divided by 644.

Let's proceed 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
Subtracting 0 from 2 leaves us with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 644

Moving on to step 2:
If we divide 28 by 644, we get 0 and a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Fetch the next digit (9) from the dividend, attach it to 28 and continue: 289 / 644

Moving on to step 3:
The number 644 fits into 289 0 times, leaving a remainder of 289.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 289, we end up with 289.
Grab the next digit (2) from the dividend, add it to 289, then carry on: 2892 / 644

Let's proceed to step 4:
When dividing 2892 by 644, we get 4 with a remainder of 316.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 2576 from 2892 and we're left with 316.
Append the next digit (2) from the dividend to 316 and continue with: 3162 / 644

On to step 5:
644 can be fit into 3162 4 times, resulting in a remainder of 586.
Put 4 as the next digit of the answer. 
Result so far: 44.0
If we take 2576 away from 3162, we end up with 586.
Include the next digit (7) from the dividend after 586, then repeat: 5867 / 644

Advancing to step 6:
The number 644 fits into 5867 9 times, leaving a remainder of 71.
The next digit of our result is 9. 
Result so far: 449.0
Subtract 5796 from 5867 to get 71.
Bring next digit (8) of the dividend behind the 71 and repeat the process: 718 / 644

Moving on to step 7:
If we divide 718 by 644, we get 1 and a remainder of 74.
Use 1 as the next digit of our solution. 
Result so far: 4491.0
If we take 644 away from 718, we end up with 74.
Grab the next digit (3) from the dividend, add it to 74, then carry on: 743 / 644

On to step 8:
644 can be fit into 743 1 times, resulting in a remainder of 99.
Record the quotient 1 as the next digit in the result. 
Result so far: 44911.0
If we take 644 away from 743, we end up with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Let's proceed to step 9:
990 divided by 644 is 1 with a remainder of 346.
Record the quotient 1 as the next digit in the result. 
Result so far: 44911.1
The remainder is 346 after subtracting 644 from 990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Step 10:
3460 divided by 644 is 5 with a remainder of 240.
The next digit of our result is 5. 
Result so far: 44911.15
Deduct 3220 from 3460 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 11:
The number 644 fits into 2400 3 times, leaving a remainder of 468.
Write down 3 as next digit of the result. 
Result so far: 44911.153
Deduct 1932 from 2400 and we're left with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

On to step 12:
If we divide 4680 by 644, we get 7 and a remainder of 172.
The number 7 becomes the next digit in our result. 
Result so far: 44911.1537
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.

Going ahead to step 13:
The number 644 fits into 1720 2 times, leaving a remainder of 432.
Put 2 as the next digit of the answer. 
Result so far: 44911.15372
If we take 1288 away from 1720, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Going ahead to step 14:
644 can be fit into 4320 6 times, resulting in a remainder of 456.
Write down 6 as next digit of the result. 
Result so far: 44911.153726
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.

Moving on to step 15:
4560 divided by 644 is 7 with a remainder of 52.
Record the quotient 7 as the next digit in the result. 
Result so far: 44911.1537267
Deduct 4508 from 4560 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 16:
520 divided by 644 is 0 with a remainder of 520.
The next digit of our result is 0. 
Result so far: 44911.1537267
If we subtract 0 from 520, we get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

After the division, we end up with 44911.1537267 and a remainder of 5.2e-07.
