We look at the division of 12902169 by 318 
We want to divide 12902169 by 318.

Let's proceed to step 1:
When dividing 1 by 318, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 318

Let's proceed to step 2:
12 divided by 318 is 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 318

Moving on to step 3:
When dividing 129 by 318, we get 0 with a remainder of 129.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 129 and we're left with 129.
Include the next digit (0) from the dividend after 129, then repeat: 1290 / 318

Moving on to step 4:
The number 318 fits into 1290 4 times, leaving a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 1272 from 1290 and we're left with 18.
Bring next digit (2) of the dividend behind the 18 and repeat the process: 182 / 318

Advancing to step 5:
The number 318 fits into 182 0 times, leaving a remainder of 182.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Subtract 0 from 182 to get 182.
Bring next digit (1) of the dividend behind the 182 and repeat the process: 1821 / 318

Advancing to step 6:
318 goes into 1821 5 times with a remainder of 231.
Write down 5 as next digit of the result. 
Result so far: 405.0
Subtract 1590 from 1821 to get 231.
Bring next digit (6) of the dividend behind the 231 and repeat the process: 2316 / 318

Moving on to step 7:
The number 318 fits into 2316 7 times, leaving a remainder of 90.
The next digit of our result is 7. 
Result so far: 4057.0
Deduct 2226 from 2316 and we're left with 90.
Include the next digit (9) from the dividend after 90, then repeat: 909 / 318

On to step 8:
The number 318 fits into 909 2 times, leaving a remainder of 273.
Use 2 as the next digit of our solution. 
Result so far: 40572.0
The remainder is 273 after subtracting 636 from 909.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

On to step 9:
318 goes into 2730 8 times with a remainder of 186.
The next digit of our result is 8. 
Result so far: 40572.8
The remainder is 186 after subtracting 2544 from 2730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Moving on to step 10:
The number 318 fits into 1860 5 times, leaving a remainder of 270.
Write down 5 as next digit of the result. 
Result so far: 40572.85
If we subtract 1590 from 1860, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 11:
If we divide 2700 by 318, we get 8 and a remainder of 156.
Put 8 as the next digit of the answer. 
Result so far: 40572.858
Subtracting 2544 from 2700 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 12:
318 can be fit into 1560 4 times, resulting in a remainder of 288.
Record the quotient 4 as the next digit in the result. 
Result so far: 40572.8584
The remainder is 288 after subtracting 1272 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 13:
318 goes into 2880 9 times with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 40572.85849
Subtracting 2862 from 2880 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 14:
If we divide 180 by 318, we get 0 and a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 40572.85849
Deduct 0 from 180 and we're left 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.

Step 15:
318 goes into 1800 5 times with a remainder of 210.
Write down 5 as next digit of the result. 
Result so far: 40572.8584905
Deduct 1590 from 1800 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 16:
If we divide 2100 by 318, we get 6 and a remainder of 192.
Put 6 as the next digit of the answer. 
Result so far: 40572.85849056
Subtracting 1908 from 2100 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

The quotient of the division is 40572.85849056, and the remainder is 1.92e-07.
