We're dividing 82659847 by 644 
We want to divide 82659847 by 644.

Advancing to step 1:
If we divide 8 by 644, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 644

Going ahead to step 2:
644 can be fit into 82 0 times, resulting in a remainder of 82.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 82 to get 82.
Append the next digit (6) from the dividend to 82 and continue with: 826 / 644

Let's proceed to step 3:
826 divided by 644 is 1 with a remainder of 182.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 644 away from 826, we end up with 182.
Bring next digit (5) of the dividend behind the 182 and repeat the process: 1825 / 644

Moving on to step 4:
When dividing 1825 by 644, we get 2 with a remainder of 537.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 1288 away from 1825, we end up with 537.
Grab the next digit (9) from the dividend, add it to 537, then carry on: 5379 / 644

Moving on to step 5:
644 can be fit into 5379 8 times, resulting in a remainder of 227.
The number 8 becomes the next digit in our result. 
Result so far: 128.0
Subtracting 5152 from 5379 leaves us with 227.
Include the next digit (8) from the dividend after 227, then repeat: 2278 / 644

Advancing to step 6:
If we divide 2278 by 644, we get 3 and a remainder of 346.
The next digit of our result is 3. 
Result so far: 1283.0
Subtract 1932 from 2278 to get 346.
Grab the next digit (4) from the dividend, add it to 346, then carry on: 3464 / 644

Step 7:
When dividing 3464 by 644, we get 5 with a remainder of 244.
Use 5 as the next digit of our solution. 
Result so far: 12835.0
Deduct 3220 from 3464 and we're left with 244.
Fetch the next digit (7) from the dividend, attach it to 244 and continue: 2447 / 644

Advancing to step 8:
2447 divided by 644 is 3 with a remainder of 515.
The next digit of our result is 3. 
Result so far: 128353.0
Deduct 1932 from 2447 and we're left with 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Moving on to step 9:
If we divide 5150 by 644, we get 7 and a remainder of 642.
Put 7 as the next digit of the answer. 
Result so far: 128353.7
If we subtract 4508 from 5150, we get 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

Moving on to step 10:
644 can be fit into 6420 9 times, resulting in a remainder of 624.
Write down 9 as next digit of the result. 
Result so far: 128353.79
If we take 5796 away from 6420, we end up with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

On to step 11:
644 can be fit into 6240 9 times, resulting in a remainder of 444.
Use 9 as the next digit of our solution. 
Result so far: 128353.799
If we subtract 5796 from 6240, we 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.

The final result is 128353.799 with a remainder of 0.0444.
