We look at the division of 81219303 by 260 
We're looking to find how many times 260 goes into 81219303.

Going ahead to step 1:
The number 260 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 260

Let's proceed to step 2:
If we divide 81 by 260, we get 0 and a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Bring next digit (2) of the dividend behind the 81 and repeat the process: 812 / 260

Step 3:
812 divided by 260 is 3 with a remainder of 32.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 780 from 812 to get 32.
Take the next digit (1) from the dividend and append it to 32, then repeat: 321 / 260

Step 4:
If we divide 321 by 260, we get 1 and a remainder of 61.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we take 260 away from 321, we end up with 61.
Include the next digit (9) from the dividend after 61, then repeat: 619 / 260

Step 5:
619 divided by 260 is 2 with a remainder of 99.
The next digit of our result is 2. 
Result so far: 312.0
Deduct 520 from 619 and we're left with 99.
Take the next digit (3) from the dividend and append it to 99, then repeat: 993 / 260

Let's proceed to step 6:
993 divided by 260 is 3 with a remainder of 213.
Write down 3 as next digit of the result. 
Result so far: 3123.0
Deduct 780 from 993 and we're left with 213.
Include the next digit (0) from the dividend after 213, then repeat: 2130 / 260

Moving on to step 7:
260 can be fit into 2130 8 times, resulting in a remainder of 50.
Put 8 as the next digit of the answer. 
Result so far: 31238.0
Subtracting 2080 from 2130 leaves us with 50.
Grab the next digit (3) from the dividend, add it to 50, then carry on: 503 / 260

Step 8:
If we divide 503 by 260, we get 1 and a remainder of 243.
Put 1 as the next digit of the answer. 
Result so far: 312381.0
Subtracting 260 from 503 leaves us with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

On to step 9:
2430 divided by 260 is 9 with a remainder of 90.
The number 9 becomes the next digit in our result. 
Result so far: 312381.9
Subtract 2340 from 2430 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 10:
900 divided by 260 is 3 with a remainder of 120.
Record the quotient 3 as the next digit in the result. 
Result so far: 312381.93
If we subtract 780 from 900, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 11:
1200 divided by 260 is 4 with a remainder of 160.
The next digit of our result is 4. 
Result so far: 312381.934
If we take 1040 away from 1200, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 12:
1600 divided by 260 is 6 with a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 312381.9346
Deduct 1560 from 1600 and we're left with 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 13:
260 can be fit into 400 1 times, resulting in a remainder of 140.
Put 1 as the next digit of the answer. 
Result so far: 312381.93461
Subtracting 260 from 400 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 14:
If we divide 1400 by 260, we get 5 and a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 312381.934615
If we take 1300 away from 1400, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 15:
260 can be fit into 1000 3 times, resulting in a remainder of 220.
The number 3 becomes the next digit in our result. 
Result so far: 312381.9346153
Subtract 780 from 1000 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 16:
2200 divided by 260 is 8 with a remainder of 120.
The number 8 becomes the next digit in our result. 
Result so far: 312381.93461538
If we subtract 2080 from 2200, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final outcome is 312381.93461538, with a leftover of 1.2e-07.
