We look at the division of 85527293 by 644 
Let's see how many times 644 fits into 85527293.

Going ahead to step 1:
644 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 644

Going ahead to step 2:
644 goes into 85 0 times with a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Take the next digit (5) from the dividend and append it to 85, then repeat: 855 / 644

Let's proceed to step 3:
If we divide 855 by 644, we get 1 and a remainder of 211.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 644 from 855, we get 211.
Take the next digit (2) from the dividend and append it to 211, then repeat: 2112 / 644

Step 4:
644 can be fit into 2112 3 times, resulting in a remainder of 180.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 1932 from 2112 leaves us with 180.
Take the next digit (7) from the dividend and append it to 180, then repeat: 1807 / 644

Step 5:
If we divide 1807 by 644, we get 2 and a remainder of 519.
Write down 2 as next digit of the result. 
Result so far: 132.0
If we take 1288 away from 1807, we end up with 519.
Fetch the next digit (2) from the dividend, attach it to 519 and continue: 5192 / 644

Let's proceed to step 6:
644 can be fit into 5192 8 times, resulting in a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 1328.0
Subtract 5152 from 5192 to get 40.
Fetch the next digit (9) from the dividend, attach it to 40 and continue: 409 / 644

Going ahead to step 7:
When dividing 409 by 644, we get 0 with a remainder of 409.
Put 0 as the next digit of the answer. 
Result so far: 13280.0
Subtract 0 from 409 to get 409.
Grab the next digit (3) from the dividend, add it to 409, then carry on: 4093 / 644

On to step 8:
644 can be fit into 4093 6 times, resulting in a remainder of 229.
Use 6 as the next digit of our solution. 
Result so far: 132806.0
If we subtract 3864 from 4093, we get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Moving on to step 9:
644 can be fit into 2290 3 times, resulting in a remainder of 358.
Write down 3 as next digit of the result. 
Result so far: 132806.3
The remainder is 358 after subtracting 1932 from 2290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Advancing to step 10:
644 can be fit into 3580 5 times, resulting in a remainder of 360.
Put 5 as the next digit of the answer. 
Result so far: 132806.35
If we subtract 3220 from 3580, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 11:
644 can be fit into 3600 5 times, resulting in a remainder of 380.
Put 5 as the next digit of the answer. 
Result so far: 132806.355
The remainder is 380 after subtracting 3220 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

After the division, we end up with 132806.355 and a remainder of 0.038.
