We look at the division of 85521109 by 260 
We want to divide 85521109 by 260.

Step 1:
When dividing 8 by 260, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 260

Advancing to step 2:
The number 260 fits into 85 0 times, leaving a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Grab the next digit (5) from the dividend, add it to 85, then carry on: 855 / 260

On to step 3:
855 divided by 260 is 3 with a remainder of 75.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 780 from 855 to get 75.
Append the next digit (2) from the dividend to 75 and continue with: 752 / 260

Going ahead to step 4:
752 divided by 260 is 2 with a remainder of 232.
Use 2 as the next digit of our solution. 
Result so far: 32.0
If we subtract 520 from 752, we get 232.
Take the next digit (1) from the dividend and append it to 232, then repeat: 2321 / 260

Let's proceed to step 5:
260 goes into 2321 8 times with a remainder of 241.
The number 8 becomes the next digit in our result. 
Result so far: 328.0
If we subtract 2080 from 2321, we get 241.
Take the next digit (1) from the dividend and append it to 241, then repeat: 2411 / 260

Step 6:
2411 divided by 260 is 9 with a remainder of 71.
Use 9 as the next digit of our solution. 
Result so far: 3289.0
If we take 2340 away from 2411, we end up with 71.
Fetch the next digit (0) from the dividend, attach it to 71 and continue: 710 / 260

On to step 7:
260 can be fit into 710 2 times, resulting in a remainder of 190.
The number 2 becomes the next digit in our result. 
Result so far: 32892.0
If we take 520 away from 710, we end up with 190.
Bring next digit (9) of the dividend behind the 190 and repeat the process: 1909 / 260

Moving on to step 8:
260 goes into 1909 7 times with a remainder of 89.
Write down 7 as next digit of the result. 
Result so far: 328927.0
If we subtract 1820 from 1909, we get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 9:
260 can be fit into 890 3 times, resulting in a remainder of 110.
Record the quotient 3 as the next digit in the result. 
Result so far: 328927.3
Deduct 780 from 890 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 10:
260 goes into 1100 4 times with a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 328927.34
Subtract 1040 from 1100 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
If we divide 600 by 260, we get 2 and a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 328927.342
Subtracting 520 from 600 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 12:
If we divide 800 by 260, we get 3 and a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 328927.3423
Subtracting 780 from 800 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
260 can be fit into 200 0 times, resulting in a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 328927.3423
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 14:
The number 260 fits into 2000 7 times, leaving a remainder of 180.
Use 7 as the next digit of our solution. 
Result so far: 328927.342307
If we subtract 1820 from 2000, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 15:
If we divide 1800 by 260, we get 6 and a remainder of 240.
Use 6 as the next digit of our solution. 
Result so far: 328927.3423076
Subtract 1560 from 1800 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 16:
If we divide 2400 by 260, we get 9 and a remainder of 60.
Put 9 as the next digit of the answer. 
Result so far: 328927.34230769
If we subtract 2340 from 2400, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 328927.34230769, with a leftover of 6e-08.
