13512274 ÷ 395 
We want to figure out the number of times 13512274 can be divided by 395.

Step 1:
If we divide 1 by 395, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 395

On to step 2:
If we divide 13 by 395, we get 0 and a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 395

Advancing to step 3:
The number 395 fits into 135 0 times, leaving a remainder of 135.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 135 leaves us with 135.
Append the next digit (1) from the dividend to 135 and continue with: 1351 / 395

Let's proceed to step 4:
When dividing 1351 by 395, we get 3 with a remainder of 166.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 166 after subtracting 1185 from 1351.
Append the next digit (2) from the dividend to 166 and continue with: 1662 / 395

Moving on to step 5:
The number 395 fits into 1662 4 times, leaving a remainder of 82.
Use 4 as the next digit of our solution. 
Result so far: 34.0
The remainder is 82 after subtracting 1580 from 1662.
Bring next digit (2) of the dividend behind the 82 and repeat the process: 822 / 395

Moving on to step 6:
395 goes into 822 2 times with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 342.0
Subtracting 790 from 822 leaves us with 32.
Append the next digit (7) from the dividend to 32 and continue with: 327 / 395

On to step 7:
If we divide 327 by 395, we get 0 and a remainder of 327.
The number 0 becomes the next digit in our result. 
Result so far: 3420.0
Deduct 0 from 327 and we're left with 327.
Bring next digit (4) of the dividend behind the 327 and repeat the process: 3274 / 395

Let's proceed to step 8:
395 can be fit into 3274 8 times, resulting in a remainder of 114.
Record the quotient 8 as the next digit in the result. 
Result so far: 34208.0
Deduct 3160 from 3274 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 9:
When dividing 1140 by 395, we get 2 with a remainder of 350.
Record the quotient 2 as the next digit in the result. 
Result so far: 34208.2
Subtract 790 from 1140 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 10:
395 goes into 3500 8 times with a remainder of 340.
Write down 8 as next digit of the result. 
Result so far: 34208.28
If we subtract 3160 from 3500, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 11:
If we divide 3400 by 395, we get 8 and a remainder of 240.
Write down 8 as next digit of the result. 
Result so far: 34208.288
If we subtract 3160 from 3400, we 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.

The final outcome is 34208.288, with a leftover of 0.024.
