We're dividing 12665406 by 358 
We want to figure out the number of times 12665406 can be divided by 358.

Let's proceed to step 1:
358 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 358

Going ahead to step 2:
The number 358 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 358

Let's proceed to step 3:
358 goes into 126 0 times with a remainder of 126.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 126 leaves us with 126.
Include the next digit (6) from the dividend after 126, then repeat: 1266 / 358

Let's proceed to step 4:
When dividing 1266 by 358, we get 3 with a remainder of 192.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 1074 from 1266 and we're left with 192.
Take the next digit (5) from the dividend and append it to 192, then repeat: 1925 / 358

Advancing to step 5:
When dividing 1925 by 358, we get 5 with a remainder of 135.
Write down 5 as next digit of the result. 
Result so far: 35.0
The remainder is 135 after subtracting 1790 from 1925.
Grab the next digit (4) from the dividend, add it to 135, then carry on: 1354 / 358

Going ahead to step 6:
If we divide 1354 by 358, we get 3 and a remainder of 280.
Record the quotient 3 as the next digit in the result. 
Result so far: 353.0
The remainder is 280 after subtracting 1074 from 1354.
Include the next digit (0) from the dividend after 280, then repeat: 2800 / 358

Let's proceed to step 7:
358 goes into 2800 7 times with a remainder of 294.
The next digit of our result is 7. 
Result so far: 3537.0
Subtract 2506 from 2800 to get 294.
Fetch the next digit (6) from the dividend, attach it to 294 and continue: 2946 / 358

Step 8:
If we divide 2946 by 358, we get 8 and a remainder of 82.
Record the quotient 8 as the next digit in the result. 
Result so far: 35378.0
If we take 2864 away from 2946, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 9:
820 divided by 358 is 2 with a remainder of 104.
The next digit of our result is 2. 
Result so far: 35378.2
Deduct 716 from 820 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 10:
If we divide 1040 by 358, we get 2 and a remainder of 324.
Record the quotient 2 as the next digit in the result. 
Result so far: 35378.22
If we subtract 716 from 1040, we get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

The final result is 35378.22 with a remainder of 0.324.
