12039802 ÷ 868 
Let's see how many times 868 fits into 12039802.

Advancing to step 1:
1 divided by 868 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 868

Let's proceed to step 2:
12 divided by 868 is 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 868

Let's proceed to step 3:
When dividing 120 by 868, we get 0 with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 120 to get 120.
Take the next digit (3) from the dividend and append it to 120, then repeat: 1203 / 868

Advancing to step 4:
868 can be fit into 1203 1 times, resulting in a remainder of 335.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 868 from 1203, we get 335.
Fetch the next digit (9) from the dividend, attach it to 335 and continue: 3359 / 868

Going ahead to step 5:
3359 divided by 868 is 3 with a remainder of 755.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 2604 from 3359, we get 755.
Include the next digit (8) from the dividend after 755, then repeat: 7558 / 868

Step 6:
When dividing 7558 by 868, we get 8 with a remainder of 614.
Record the quotient 8 as the next digit in the result. 
Result so far: 138.0
If we take 6944 away from 7558, we end up with 614.
Append the next digit (0) from the dividend to 614 and continue with: 6140 / 868

On to step 7:
The number 868 fits into 6140 7 times, leaving a remainder of 64.
Use 7 as the next digit of our solution. 
Result so far: 1387.0
Subtract 6076 from 6140 to get 64.
Fetch the next digit (2) from the dividend, attach it to 64 and continue: 642 / 868

Moving on to step 8:
868 can be fit into 642 0 times, resulting in a remainder of 642.
Put 0 as the next digit of the answer. 
Result so far: 13870.0
If we take 0 away from 642, we end up with 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

On to step 9:
If we divide 6420 by 868, we get 7 and a remainder of 344.
Write down 7 as next digit of the result. 
Result so far: 13870.7
If we subtract 6076 from 6420, we get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 10:
868 can be fit into 3440 3 times, resulting in a remainder of 836.
The next digit of our result is 3. 
Result so far: 13870.73
The remainder is 836 after subtracting 2604 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8360, and continue the process.

On to step 11:
868 can be fit into 8360 9 times, resulting in a remainder of 548.
The next digit of our result is 9. 
Result so far: 13870.739
The remainder is 548 after subtracting 7812 from 8360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

On to step 12:
868 goes into 5480 6 times with a remainder of 272.
The next digit of our result is 6. 
Result so far: 13870.7396
The remainder is 272 after subtracting 5208 from 5480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Moving on to step 13:
The number 868 fits into 2720 3 times, leaving a remainder of 116.
Use 3 as the next digit of our solution. 
Result so far: 13870.73963
If we subtract 2604 from 2720, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 14:
If we divide 1160 by 868, we get 1 and a remainder of 292.
Record the quotient 1 as the next digit in the result. 
Result so far: 13870.739631
Subtracting 868 from 1160 leaves us with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Going ahead to step 15:
The number 868 fits into 2920 3 times, leaving a remainder of 316.
Write down 3 as next digit of the result. 
Result so far: 13870.7396313
Deduct 2604 from 2920 and we're left with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 16:
The number 868 fits into 3160 3 times, leaving a remainder of 556.
Record the quotient 3 as the next digit in the result. 
Result so far: 13870.73963133
If we subtract 2604 from 3160, we get 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

After the division, we end up with 13870.73963133 and a remainder of 5.56e-07.
