1258292 ÷ 260 
We want to figure out the number of times 1258292 can be divided by 260.

Going ahead to step 1:
The number 260 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 260

Going ahead to step 2:
12 divided by 260 is 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 260

Step 3:
125 divided by 260 is 0 with a remainder of 125.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 125, we get 125.
Fetch the next digit (8) from the dividend, attach it to 125 and continue: 1258 / 260

Advancing to step 4:
When dividing 1258 by 260, we get 4 with a remainder of 218.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 1040 from 1258 and we're left with 218.
Include the next digit (2) from the dividend after 218, then repeat: 2182 / 260

Moving on to step 5:
2182 divided by 260 is 8 with a remainder of 102.
Use 8 as the next digit of our solution. 
Result so far: 48.0
Subtracting 2080 from 2182 leaves us with 102.
Fetch the next digit (9) from the dividend, attach it to 102 and continue: 1029 / 260

On to step 6:
When dividing 1029 by 260, we get 3 with a remainder of 249.
Use 3 as the next digit of our solution. 
Result so far: 483.0
If we take 780 away from 1029, we end up with 249.
Fetch the next digit (2) from the dividend, attach it to 249 and continue: 2492 / 260

On to step 7:
260 goes into 2492 9 times with a remainder of 152.
The number 9 becomes the next digit in our result. 
Result so far: 4839.0
The remainder is 152 after subtracting 2340 from 2492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 8:
The number 260 fits into 1520 5 times, leaving a remainder of 220.
The number 5 becomes the next digit in our result. 
Result so far: 4839.5
If we take 1300 away from 1520, we end up 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.

On to step 9:
The number 260 fits into 2200 8 times, leaving a remainder of 120.
Write down 8 as next digit of the result. 
Result so far: 4839.58
If we take 2080 away from 2200, we end up with 120.
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 10:
If we divide 1200 by 260, we get 4 and a remainder of 160.
Put 4 as the next digit of the answer. 
Result so far: 4839.584
Subtract 1040 from 1200 to 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.

Advancing to step 11:
260 can be fit into 1600 6 times, resulting in a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 4839.5846
Subtract 1560 from 1600 to get 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 12:
If we divide 400 by 260, we get 1 and a remainder of 140.
The next digit of our result is 1. 
Result so far: 4839.58461
Deduct 260 from 400 and we're left 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 13:
260 can be fit into 1400 5 times, resulting in a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 4839.584615
The remainder is 100 after subtracting 1300 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 14:
1000 divided by 260 is 3 with a remainder of 220.
The number 3 becomes the next digit in our result. 
Result so far: 4839.5846153
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.

Let's proceed to step 15:
260 can be fit into 2200 8 times, resulting in a remainder of 120.
The number 8 becomes the next digit in our result. 
Result so far: 4839.58461538
Subtract 2080 from 2200 to 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 result is 4839.58461538 with a remainder of 1.2e-07.
