49817656 divided by 644 
Let's see how many times 644 fits into 49817656.

Advancing to step 1:
644 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 644

Step 2:
When dividing 49 by 644, we get 0 with a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 49 to get 49.
Grab the next digit (8) from the dividend, add it to 49, then carry on: 498 / 644

Let's proceed to step 3:
644 goes into 498 0 times with a remainder of 498.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 498 and we're left with 498.
Include the next digit (1) from the dividend after 498, then repeat: 4981 / 644

On to step 4:
When dividing 4981 by 644, we get 7 with a remainder of 473.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 4508 from 4981 leaves us with 473.
Take the next digit (7) from the dividend and append it to 473, then repeat: 4737 / 644

Let's proceed to step 5:
If we divide 4737 by 644, we get 7 and a remainder of 229.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
If we take 4508 away from 4737, we end up with 229.
Take the next digit (6) from the dividend and append it to 229, then repeat: 2296 / 644

On to step 6:
2296 divided by 644 is 3 with a remainder of 364.
The number 3 becomes the next digit in our result. 
Result so far: 773.0
Subtracting 1932 from 2296 leaves us with 364.
Take the next digit (5) from the dividend and append it to 364, then repeat: 3645 / 644

Advancing to step 7:
If we divide 3645 by 644, we get 5 and a remainder of 425.
Record the quotient 5 as the next digit in the result. 
Result so far: 7735.0
If we subtract 3220 from 3645, we get 425.
Grab the next digit (6) from the dividend, add it to 425, then carry on: 4256 / 644

On to step 8:
644 goes into 4256 6 times with a remainder of 392.
Use 6 as the next digit of our solution. 
Result so far: 77356.0
The remainder is 392 after subtracting 3864 from 4256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Let's proceed to step 9:
644 can be fit into 3920 6 times, resulting in a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 77356.6
The remainder is 56 after subtracting 3864 from 3920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 10:
644 can be fit into 560 0 times, resulting in a remainder of 560.
The number 0 becomes the next digit in our result. 
Result so far: 77356.6
Subtract 0 from 560 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 11:
When dividing 5600 by 644, we get 8 with a remainder of 448.
Write down 8 as next digit of the result. 
Result so far: 77356.608
Deduct 5152 from 5600 and we're left with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Step 12:
When dividing 4480 by 644, we get 6 with a remainder of 616.
The next digit of our result is 6. 
Result so far: 77356.6086
The remainder is 616 after subtracting 3864 from 4480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Let's proceed to step 13:
644 goes into 6160 9 times with a remainder of 364.
Record the quotient 9 as the next digit in the result. 
Result so far: 77356.60869
The remainder is 364 after subtracting 5796 from 6160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Going ahead to step 14:
The number 644 fits into 3640 5 times, leaving a remainder of 420.
Use 5 as the next digit of our solution. 
Result so far: 77356.608695
Subtracting 3220 from 3640 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Step 15:
If we divide 4200 by 644, we get 6 and a remainder of 336.
Record the quotient 6 as the next digit in the result. 
Result so far: 77356.6086956
Deduct 3864 from 4200 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 16:
When dividing 3360 by 644, we get 5 with a remainder of 140.
Record the quotient 5 as the next digit in the result. 
Result so far: 77356.60869565
Deduct 3220 from 3360 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Our division results in 77356.60869565 with a remaining 1.4e-07.
