Let's divide 12857818 by 699
Let's see how many times 699 fits into 12857818.

Moving on to step 1:
The number 699 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 699

Moving on to step 2:
699 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 699

Advancing to step 3:
If we divide 128 by 699, we get 0 and a remainder of 128.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 128 and we're left with 128.
Grab the next digit (5) from the dividend, add it to 128, then carry on: 1285 / 699

On to step 4:
699 goes into 1285 1 times with a remainder of 586.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 586 after subtracting 699 from 1285.
Grab the next digit (7) from the dividend, add it to 586, then carry on: 5867 / 699

On to step 5:
The number 699 fits into 5867 8 times, leaving a remainder of 275.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we subtract 5592 from 5867, we get 275.
Fetch the next digit (8) from the dividend, attach it to 275 and continue: 2758 / 699

Going ahead to step 6:
When dividing 2758 by 699, we get 3 with a remainder of 661.
The next digit of our result is 3. 
Result so far: 183.0
Subtract 2097 from 2758 to get 661.
Include the next digit (1) from the dividend after 661, then repeat: 6611 / 699

On to step 7:
6611 divided by 699 is 9 with a remainder of 320.
Use 9 as the next digit of our solution. 
Result so far: 1839.0
If we take 6291 away from 6611, we end up with 320.
Include the next digit (8) from the dividend after 320, then repeat: 3208 / 699

Going ahead to step 8:
If we divide 3208 by 699, we get 4 and a remainder of 412.
The next digit of our result is 4. 
Result so far: 18394.0
Deduct 2796 from 3208 and we're left with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Advancing to step 9:
699 can be fit into 4120 5 times, resulting in a remainder of 625.
Write down 5 as next digit of the result. 
Result so far: 18394.5
Deduct 3495 from 4120 and we're left with 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Advancing to step 10:
699 goes into 6250 8 times with a remainder of 658.
Use 8 as the next digit of our solution. 
Result so far: 18394.58
Subtracting 5592 from 6250 leaves us with 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

Moving on to step 11:
699 can be fit into 6580 9 times, resulting in a remainder of 289.
Use 9 as the next digit of our solution. 
Result so far: 18394.589
If we subtract 6291 from 6580, we get 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Let's proceed to step 12:
If we divide 2890 by 699, we get 4 and a remainder of 94.
The next digit of our result is 4. 
Result so far: 18394.5894
If we take 2796 away from 2890, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 13:
940 divided by 699 is 1 with a remainder of 241.
The number 1 becomes the next digit in our result. 
Result so far: 18394.58941
The remainder is 241 after subtracting 699 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Moving on to step 14:
The number 699 fits into 2410 3 times, leaving a remainder of 313.
Use 3 as the next digit of our solution. 
Result so far: 18394.589413
The remainder is 313 after subtracting 2097 from 2410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Moving on to step 15:
When dividing 3130 by 699, we get 4 with a remainder of 334.
Put 4 as the next digit of the answer. 
Result so far: 18394.5894134
Deduct 2796 from 3130 and we're left with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Step 16:
When dividing 3340 by 699, we get 4 with a remainder of 544.
The number 4 becomes the next digit in our result. 
Result so far: 18394.58941344
If we take 2796 away from 3340, we end up with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

The final result is 18394.58941344 with a remainder of 5.44e-07.
