80197937 ÷ 260 
We want to figure out the number of times 80197937 can be divided by 260.

Let's proceed to step 1:
When dividing 8 by 260, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 260

Moving on to step 2:
The number 260 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Take the next digit (1) from the dividend and append it to 80, then repeat: 801 / 260

Advancing to step 3:
260 can be fit into 801 3 times, resulting in a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 780 from 801 to get 21.
Bring next digit (9) of the dividend behind the 21 and repeat the process: 219 / 260

On to step 4:
219 divided by 260 is 0 with a remainder of 219.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
If we take 0 away from 219, we end up with 219.
Bring next digit (7) of the dividend behind the 219 and repeat the process: 2197 / 260

Moving on to step 5:
260 can be fit into 2197 8 times, resulting in a remainder of 117.
The number 8 becomes the next digit in our result. 
Result so far: 308.0
The remainder is 117 after subtracting 2080 from 2197.
Bring next digit (9) of the dividend behind the 117 and repeat the process: 1179 / 260

Advancing to step 6:
If we divide 1179 by 260, we get 4 and a remainder of 139.
Put 4 as the next digit of the answer. 
Result so far: 3084.0
Subtracting 1040 from 1179 leaves us with 139.
Bring next digit (3) of the dividend behind the 139 and repeat the process: 1393 / 260

Step 7:
1393 divided by 260 is 5 with a remainder of 93.
Write down 5 as next digit of the result. 
Result so far: 30845.0
Deduct 1300 from 1393 and we're left with 93.
Grab the next digit (7) from the dividend, add it to 93, then carry on: 937 / 260

Moving on to step 8:
260 can be fit into 937 3 times, resulting in a remainder of 157.
Use 3 as the next digit of our solution. 
Result so far: 308453.0
If we take 780 away from 937, we end up with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Moving on to step 9:
260 goes into 1570 6 times with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 308453.6
Subtract 1560 from 1570 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
260 goes into 100 0 times with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 308453.6
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 11:
If we divide 1000 by 260, we get 3 and a remainder of 220.
The next digit of our result is 3. 
Result so far: 308453.603
Subtracting 780 from 1000 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 12:
When dividing 2200 by 260, we get 8 with a remainder of 120.
The next digit of our result is 8. 
Result so far: 308453.6038
The remainder is 120 after subtracting 2080 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 13:
260 goes into 1200 4 times with a remainder of 160.
The next digit of our result is 4. 
Result so far: 308453.60384
If we subtract 1040 from 1200, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 14:
If we divide 1600 by 260, we get 6 and a remainder of 40.
The next digit of our result is 6. 
Result so far: 308453.603846
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.

Let's proceed to step 15:
400 divided by 260 is 1 with a remainder of 140.
Put 1 as the next digit of the answer. 
Result so far: 308453.6038461
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.

Advancing to step 16:
When dividing 1400 by 260, we get 5 with a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 308453.60384615
If we subtract 1300 from 1400, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 308453.60384615 with a remainder of 1e-07.
