We look at the division of 49532774 by 644 
We're looking to find how many times 644 goes into 49532774.

Advancing to step 1:
644 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 644

Step 2:
644 can be fit into 49 0 times, resulting in a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Bring next digit (5) of the dividend behind the 49 and repeat the process: 495 / 644

Step 3:
495 divided by 644 is 0 with a remainder of 495.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 495, we end up with 495.
Grab the next digit (3) from the dividend, add it to 495, then carry on: 4953 / 644

Going ahead to step 4:
If we divide 4953 by 644, we get 7 and a remainder of 445.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 4508 from 4953, we get 445.
Include the next digit (2) from the dividend after 445, then repeat: 4452 / 644

Let's proceed to step 5:
4452 divided by 644 is 6 with a remainder of 588.
Use 6 as the next digit of our solution. 
Result so far: 76.0
Subtracting 3864 from 4452 leaves us with 588.
Include the next digit (7) from the dividend after 588, then repeat: 5887 / 644

Let's proceed to step 6:
644 goes into 5887 9 times with a remainder of 91.
The number 9 becomes the next digit in our result. 
Result so far: 769.0
Deduct 5796 from 5887 and we're left with 91.
Bring next digit (7) of the dividend behind the 91 and repeat the process: 917 / 644

On to step 7:
The number 644 fits into 917 1 times, leaving a remainder of 273.
Record the quotient 1 as the next digit in the result. 
Result so far: 7691.0
Subtracting 644 from 917 leaves us with 273.
Append the next digit (4) from the dividend to 273 and continue with: 2734 / 644

On to step 8:
If we divide 2734 by 644, we get 4 and a remainder of 158.
Use 4 as the next digit of our solution. 
Result so far: 76914.0
The remainder is 158 after subtracting 2576 from 2734.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Let's proceed to step 9:
1580 divided by 644 is 2 with a remainder of 292.
Write down 2 as next digit of the result. 
Result so far: 76914.2
Deduct 1288 from 1580 and we're left with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Advancing to step 10:
644 can be fit into 2920 4 times, resulting in a remainder of 344.
Put 4 as the next digit of the answer. 
Result so far: 76914.24
If we take 2576 away from 2920, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Moving on to step 11:
The number 644 fits into 3440 5 times, leaving a remainder of 220.
The number 5 becomes the next digit in our result. 
Result so far: 76914.245
If we subtract 3220 from 3440, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 12:
644 goes into 2200 3 times with a remainder of 268.
Put 3 as the next digit of the answer. 
Result so far: 76914.2453
Subtract 1932 from 2200 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Moving on to step 13:
644 can be fit into 2680 4 times, resulting in a remainder of 104.
Record the quotient 4 as the next digit in the result. 
Result so far: 76914.24534
Subtracting 2576 from 2680 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 14:
If we divide 1040 by 644, we get 1 and a remainder of 396.
Write down 1 as next digit of the result. 
Result so far: 76914.245341
If we subtract 644 from 1040, we get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

On to step 15:
3960 divided by 644 is 6 with a remainder of 96.
The next digit of our result is 6. 
Result so far: 76914.2453416
Deduct 3864 from 3960 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 16:
When dividing 960 by 644, we get 1 with a remainder of 316.
The number 1 becomes the next digit in our result. 
Result so far: 76914.24534161
Subtracting 644 from 960 leaves us with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

After the division, we end up with 76914.24534161 and a remainder of 3.16e-07.
