We divide 5077455 by 644
We want to figure out the number of times 5077455 can be divided by 644.

Going ahead to step 1:
The number 644 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 644

Let's proceed to step 2:
The number 644 fits into 50 0 times, leaving a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 50, we end up with 50.
Bring next digit (7) of the dividend behind the 50 and repeat the process: 507 / 644

Let's proceed to step 3:
644 can be fit into 507 0 times, resulting in a remainder of 507.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 507, we end up with 507.
Bring next digit (7) of the dividend behind the 507 and repeat the process: 5077 / 644

Advancing to step 4:
When dividing 5077 by 644, we get 7 with a remainder of 569.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 4508 from 5077, we get 569.
Bring next digit (4) of the dividend behind the 569 and repeat the process: 5694 / 644

Going ahead to step 5:
5694 divided by 644 is 8 with a remainder of 542.
Use 8 as the next digit of our solution. 
Result so far: 78.0
If we take 5152 away from 5694, we end up with 542.
Include the next digit (5) from the dividend after 542, then repeat: 5425 / 644

On to step 6:
When dividing 5425 by 644, we get 8 with a remainder of 273.
Use 8 as the next digit of our solution. 
Result so far: 788.0
The remainder is 273 after subtracting 5152 from 5425.
Append the next digit (5) from the dividend to 273 and continue with: 2735 / 644

On to step 7:
2735 divided by 644 is 4 with a remainder of 159.
The next digit of our result is 4. 
Result so far: 7884.0
Deduct 2576 from 2735 and we're left with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Advancing to step 8:
644 goes into 1590 2 times with a remainder of 302.
Write down 2 as next digit of the result. 
Result so far: 7884.2
Subtract 1288 from 1590 to get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

On to step 9:
If we divide 3020 by 644, we get 4 and a remainder of 444.
Use 4 as the next digit of our solution. 
Result so far: 7884.24
Subtract 2576 from 3020 to get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Advancing to step 10:
4440 divided by 644 is 6 with a remainder of 576.
The next digit of our result is 6. 
Result so far: 7884.246
The remainder is 576 after subtracting 3864 from 4440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Going ahead to step 11:
5760 divided by 644 is 8 with a remainder of 608.
Use 8 as the next digit of our solution. 
Result so far: 7884.2468
Deduct 5152 from 5760 and we're left with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Advancing to step 12:
If we divide 6080 by 644, we get 9 and a remainder of 284.
Use 9 as the next digit of our solution. 
Result so far: 7884.24689
Deduct 5796 from 6080 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 13:
2840 divided by 644 is 4 with a remainder of 264.
The number 4 becomes the next digit in our result. 
Result so far: 7884.246894
If we take 2576 away from 2840, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

On to step 14:
2640 divided by 644 is 4 with a remainder of 64.
The next digit of our result is 4. 
Result so far: 7884.2468944
The remainder is 64 after subtracting 2576 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 7884.2468944 with a remainder of 6.4e-07.
