We're dividing 12818879 by 745 
We want to figure out the number of times 12818879 can be divided by 745.

Let's proceed to step 1:
745 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
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 / 745

Going ahead to step 2:
12 divided by 745 is 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 745

Moving on to step 3:
The number 745 fits into 128 0 times, leaving a remainder of 128.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 128 and we're left with 128.
Append the next digit (1) from the dividend to 128 and continue with: 1281 / 745

Going ahead to step 4:
745 goes into 1281 1 times with a remainder of 536.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 745 from 1281 to get 536.
Append the next digit (8) from the dividend to 536 and continue with: 5368 / 745

Step 5:
745 can be fit into 5368 7 times, resulting in a remainder of 153.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtracting 5215 from 5368 leaves us with 153.
Append the next digit (8) from the dividend to 153 and continue with: 1538 / 745

On to step 6:
The number 745 fits into 1538 2 times, leaving a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 172.0
If we take 1490 away from 1538, we end up with 48.
Append the next digit (7) from the dividend to 48 and continue with: 487 / 745

On to step 7:
745 can be fit into 487 0 times, resulting in a remainder of 487.
Put 0 as the next digit of the answer. 
Result so far: 1720.0
Deduct 0 from 487 and we're left with 487.
Fetch the next digit (9) from the dividend, attach it to 487 and continue: 4879 / 745

Moving on to step 8:
4879 divided by 745 is 6 with a remainder of 409.
Use 6 as the next digit of our solution. 
Result so far: 17206.0
Subtracting 4470 from 4879 leaves us with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Going ahead to step 9:
4090 divided by 745 is 5 with a remainder of 365.
Use 5 as the next digit of our solution. 
Result so far: 17206.5
Deduct 3725 from 4090 and we're left with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Let's proceed to step 10:
745 goes into 3650 4 times with a remainder of 670.
Put 4 as the next digit of the answer. 
Result so far: 17206.54
The remainder is 670 after subtracting 2980 from 3650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Moving on to step 11:
When dividing 6700 by 745, we get 8 with a remainder of 740.
The next digit of our result is 8. 
Result so far: 17206.548
Deduct 5960 from 6700 and we're left with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Advancing to step 12:
7400 divided by 745 is 9 with a remainder of 695.
Write down 9 as next digit of the result. 
Result so far: 17206.5489
The remainder is 695 after subtracting 6705 from 7400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6950, and continue the process.

Going ahead to step 13:
The number 745 fits into 6950 9 times, leaving a remainder of 245.
The number 9 becomes the next digit in our result. 
Result so far: 17206.54899
The remainder is 245 after subtracting 6705 from 6950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

The final outcome is 17206.54899, with a leftover of 0.000245.
