We look at the division of 85216268 by 646 
Let's see how many times 646 fits into 85216268.

On to step 1:
8 divided by 646 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 646

Step 2:
The number 646 fits into 85 0 times, leaving a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Fetch the next digit (2) from the dividend, attach it to 85 and continue: 852 / 646

Going ahead to step 3:
646 goes into 852 1 times with a remainder of 206.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 206 after subtracting 646 from 852.
Grab the next digit (1) from the dividend, add it to 206, then carry on: 2061 / 646

On to step 4:
When dividing 2061 by 646, we get 3 with a remainder of 123.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 1938 from 2061 leaves us with 123.
Append the next digit (6) from the dividend to 123 and continue with: 1236 / 646

Going ahead to step 5:
646 can be fit into 1236 1 times, resulting in a remainder of 590.
Put 1 as the next digit of the answer. 
Result so far: 131.0
Subtract 646 from 1236 to get 590.
Include the next digit (2) from the dividend after 590, then repeat: 5902 / 646

Let's proceed to step 6:
5902 divided by 646 is 9 with a remainder of 88.
The next digit of our result is 9. 
Result so far: 1319.0
Subtract 5814 from 5902 to get 88.
Append the next digit (6) from the dividend to 88 and continue with: 886 / 646

Moving on to step 7:
If we divide 886 by 646, we get 1 and a remainder of 240.
Record the quotient 1 as the next digit in the result. 
Result so far: 13191.0
If we take 646 away from 886, we end up with 240.
Include the next digit (8) from the dividend after 240, then repeat: 2408 / 646

Advancing to step 8:
The number 646 fits into 2408 3 times, leaving a remainder of 470.
Use 3 as the next digit of our solution. 
Result so far: 131913.0
If we subtract 1938 from 2408, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 9:
646 can be fit into 4700 7 times, resulting in a remainder of 178.
Use 7 as the next digit of our solution. 
Result so far: 131913.7
The remainder is 178 after subtracting 4522 from 4700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Moving on to step 10:
The number 646 fits into 1780 2 times, leaving a remainder of 488.
Use 2 as the next digit of our solution. 
Result so far: 131913.72
Deduct 1292 from 1780 and we're left with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Step 11:
The number 646 fits into 4880 7 times, leaving a remainder of 358.
Use 7 as the next digit of our solution. 
Result so far: 131913.727
If we take 4522 away from 4880, we end up with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Moving on to step 12:
The number 646 fits into 3580 5 times, leaving a remainder of 350.
The number 5 becomes the next digit in our result. 
Result so far: 131913.7275
If we subtract 3230 from 3580, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 13:
If we divide 3500 by 646, we get 5 and a remainder of 270.
Put 5 as the next digit of the answer. 
Result so far: 131913.72755
Subtract 3230 from 3500 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Our division results in 131913.72755 with a remaining 0.00027.
