85096608 divided by 644 
We want to figure out the number of times 85096608 can be divided by 644.

On to step 1:
8 divided by 644 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 644

Moving on to step 2:
The number 644 fits into 85 0 times, leaving a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Grab the next digit (0) from the dividend, add it to 85, then carry on: 850 / 644

On to step 3:
644 can be fit into 850 1 times, resulting in a remainder of 206.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 644 from 850, we get 206.
Take the next digit (9) from the dividend and append it to 206, then repeat: 2069 / 644

Let's proceed to step 4:
644 can be fit into 2069 3 times, resulting in a remainder of 137.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 1932 from 2069 and we're left with 137.
Append the next digit (6) from the dividend to 137 and continue with: 1376 / 644

Let's proceed to step 5:
When dividing 1376 by 644, we get 2 with a remainder of 88.
The next digit of our result is 2. 
Result so far: 132.0
Deduct 1288 from 1376 and we're left with 88.
Bring next digit (6) of the dividend behind the 88 and repeat the process: 886 / 644

Moving on to step 6:
644 can be fit into 886 1 times, resulting in a remainder of 242.
Put 1 as the next digit of the answer. 
Result so far: 1321.0
If we take 644 away from 886, we end up with 242.
Bring next digit (0) of the dividend behind the 242 and repeat the process: 2420 / 644

Going ahead to step 7:
2420 divided by 644 is 3 with a remainder of 488.
The number 3 becomes the next digit in our result. 
Result so far: 13213.0
Deduct 1932 from 2420 and we're left with 488.
Fetch the next digit (8) from the dividend, attach it to 488 and continue: 4888 / 644

Going ahead to step 8:
4888 divided by 644 is 7 with a remainder of 380.
Write down 7 as next digit of the result. 
Result so far: 132137.0
The remainder is 380 after subtracting 4508 from 4888.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 9:
3800 divided by 644 is 5 with a remainder of 580.
The next digit of our result is 5. 
Result so far: 132137.5
Subtract 3220 from 3800 to get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Advancing to step 10:
5800 divided by 644 is 9 with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 132137.59
If we subtract 5796 from 5800, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
The number 644 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 132137.59
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
644 can be fit into 400 0 times, resulting in a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 132137.59
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

In conclusion, the division gives 132137.59 with a balance of 0.004.
