We're dividing 39148215 by 260 
We want to figure out the number of times 39148215 can be divided by 260.

Moving on to step 1:
The number 260 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 260

Advancing to step 2:
260 can be fit into 39 0 times, resulting in a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 260

Going ahead to step 3:
When dividing 391 by 260, we get 1 with a remainder of 131.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 260 from 391, we get 131.
Bring next digit (4) of the dividend behind the 131 and repeat the process: 1314 / 260

On to step 4:
1314 divided by 260 is 5 with a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 1300 from 1314 to get 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 260

On to step 5:
When dividing 148 by 260, we get 0 with a remainder of 148.
The number 0 becomes the next digit in our result. 
Result so far: 150.0
Subtracting 0 from 148 leaves us with 148.
Bring next digit (2) of the dividend behind the 148 and repeat the process: 1482 / 260

Advancing to step 6:
If we divide 1482 by 260, we get 5 and a remainder of 182.
Write down 5 as next digit of the result. 
Result so far: 1505.0
The remainder is 182 after subtracting 1300 from 1482.
Take the next digit (1) from the dividend and append it to 182, then repeat: 1821 / 260

On to step 7:
260 goes into 1821 7 times with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 15057.0
Subtracting 1820 from 1821 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 260

Advancing to step 8:
260 can be fit into 15 0 times, resulting in a remainder of 15.
The next digit of our result is 0. 
Result so far: 150570.0
Deduct 0 from 15 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
150 divided by 260 is 0 with a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 150570.0
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 10:
260 goes into 1500 5 times with a remainder of 200.
Use 5 as the next digit of our solution. 
Result so far: 150570.05
Subtract 1300 from 1500 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 11:
260 goes into 2000 7 times with a remainder of 180.
Write down 7 as next digit of the result. 
Result so far: 150570.057
If we take 1820 away from 2000, we end up with 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 12:
When dividing 1800 by 260, we get 6 with a remainder of 240.
Put 6 as the next digit of the answer. 
Result so far: 150570.0576
The remainder is 240 after subtracting 1560 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 13:
2400 divided by 260 is 9 with a remainder of 60.
Use 9 as the next digit of our solution. 
Result so far: 150570.05769
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.

Step 14:
600 divided by 260 is 2 with a remainder of 80.
The next digit of our result is 2. 
Result so far: 150570.057692
Subtract 520 from 600 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 15:
800 divided by 260 is 3 with a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 150570.0576923
If we subtract 780 from 800, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 16:
The number 260 fits into 200 0 times, leaving a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 150570.0576923
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 150570.0576923, with a leftover of 2e-07.
