We're dividing 64280109 by 844 
We want to divide 64280109 by 844.

Advancing to step 1:
6 divided by 844 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 844

Advancing to step 2:
844 goes into 64 0 times with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Fetch the next digit (2) from the dividend, attach it to 64 and continue: 642 / 844

Going ahead to step 3:
The number 844 fits into 642 0 times, leaving a remainder of 642.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 642 after subtracting 0 from 642.
Append the next digit (8) from the dividend to 642 and continue with: 6428 / 844

On to step 4:
When dividing 6428 by 844, we get 7 with a remainder of 520.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 5908 from 6428 and we're left with 520.
Include the next digit (0) from the dividend after 520, then repeat: 5200 / 844

Let's proceed to step 5:
When dividing 5200 by 844, we get 6 with a remainder of 136.
Record the quotient 6 as the next digit in the result. 
Result so far: 76.0
Deduct 5064 from 5200 and we're left with 136.
Append the next digit (1) from the dividend to 136 and continue with: 1361 / 844

Let's proceed to step 6:
If we divide 1361 by 844, we get 1 and a remainder of 517.
Use 1 as the next digit of our solution. 
Result so far: 761.0
If we subtract 844 from 1361, we get 517.
Append the next digit (0) from the dividend to 517 and continue with: 5170 / 844

Step 7:
If we divide 5170 by 844, we get 6 and a remainder of 106.
Write down 6 as next digit of the result. 
Result so far: 7616.0
If we subtract 5064 from 5170, we get 106.
Include the next digit (9) from the dividend after 106, then repeat: 1069 / 844

Going ahead to step 8:
When dividing 1069 by 844, we get 1 with a remainder of 225.
Write down 1 as next digit of the result. 
Result so far: 76161.0
If we take 844 away from 1069, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Advancing to step 9:
When dividing 2250 by 844, we get 2 with a remainder of 562.
Write down 2 as next digit of the result. 
Result so far: 76161.2
Subtract 1688 from 2250 to get 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Going ahead to step 10:
844 goes into 5620 6 times with a remainder of 556.
Write down 6 as next digit of the result. 
Result so far: 76161.26
The remainder is 556 after subtracting 5064 from 5620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Step 11:
The number 844 fits into 5560 6 times, leaving a remainder of 496.
Write down 6 as next digit of the result. 
Result so far: 76161.266
Subtracting 5064 from 5560 leaves us with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

In conclusion, the division gives 76161.266 with a balance of 0.0496.
