We're dividing 12571640 by 299 
Let's see how many times 299 fits into 12571640.

Step 1:
If we divide 1 by 299, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 299

Advancing to step 2:
When dividing 12 by 299, we get 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 299

Going ahead to step 3:
125 divided by 299 is 0 with a remainder of 125.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 125, we get 125.
Bring next digit (7) of the dividend behind the 125 and repeat the process: 1257 / 299

Going ahead to step 4:
If we divide 1257 by 299, we get 4 and a remainder of 61.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 61 after subtracting 1196 from 1257.
Append the next digit (1) from the dividend to 61 and continue with: 611 / 299

Moving on to step 5:
299 goes into 611 2 times with a remainder of 13.
The next digit of our result is 2. 
Result so far: 42.0
The remainder is 13 after subtracting 598 from 611.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 299

Let's proceed to step 6:
136 divided by 299 is 0 with a remainder of 136.
Use 0 as the next digit of our solution. 
Result so far: 420.0
Deduct 0 from 136 and we're left with 136.
Take the next digit (4) from the dividend and append it to 136, then repeat: 1364 / 299

Advancing to step 7:
299 goes into 1364 4 times with a remainder of 168.
The number 4 becomes the next digit in our result. 
Result so far: 4204.0
If we subtract 1196 from 1364, we get 168.
Bring next digit (0) of the dividend behind the 168 and repeat the process: 1680 / 299

Moving on to step 8:
299 goes into 1680 5 times with a remainder of 185.
The number 5 becomes the next digit in our result. 
Result so far: 42045.0
If we take 1495 away from 1680, we end up with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Going ahead to step 9:
299 goes into 1850 6 times with a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 42045.6
If we subtract 1794 from 1850, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 10:
299 can be fit into 560 1 times, resulting in a remainder of 261.
The number 1 becomes the next digit in our result. 
Result so far: 42045.61
Deduct 299 from 560 and we're left with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

On to step 11:
When dividing 2610 by 299, we get 8 with a remainder of 218.
The next digit of our result is 8. 
Result so far: 42045.618
Subtracting 2392 from 2610 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

On to step 12:
299 goes into 2180 7 times with a remainder of 87.
The next digit of our result is 7. 
Result so far: 42045.6187
If we subtract 2093 from 2180, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 13:
299 goes into 870 2 times with a remainder of 272.
Write down 2 as next digit of the result. 
Result so far: 42045.61872
Deduct 598 from 870 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 14:
299 can be fit into 2720 9 times, resulting in a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 42045.618729
If we take 2691 away from 2720, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 15:
If we divide 290 by 299, we get 0 and a remainder of 290.
The next digit of our result is 0. 
Result so far: 42045.618729
If we take 0 away from 290, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 16:
299 can be fit into 2900 9 times, resulting in a remainder of 209.
The number 9 becomes the next digit in our result. 
Result so far: 42045.61872909
Deduct 2691 from 2900 and we're left with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

In conclusion, the division gives 42045.61872909 with a balance of 2.09e-07.
