12945243 ÷ 862 
Our goal is to divide 12945243 by 862.

On to step 1:
The number 862 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 862

On to step 2:
The number 862 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 862

Let's proceed to step 3:
The number 862 fits into 129 0 times, leaving a remainder of 129.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 129 after subtracting 0 from 129.
Bring next digit (4) of the dividend behind the 129 and repeat the process: 1294 / 862

On to step 4:
862 goes into 1294 1 times with a remainder of 432.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 862 from 1294 leaves us with 432.
Append the next digit (5) from the dividend to 432 and continue with: 4325 / 862

Going ahead to step 5:
862 goes into 4325 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we subtract 4310 from 4325, we get 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 862

Moving on to step 6:
When dividing 152 by 862, we get 0 with a remainder of 152.
The number 0 becomes the next digit in our result. 
Result so far: 150.0
If we take 0 away from 152, we end up with 152.
Grab the next digit (4) from the dividend, add it to 152, then carry on: 1524 / 862

Step 7:
862 can be fit into 1524 1 times, resulting in a remainder of 662.
The number 1 becomes the next digit in our result. 
Result so far: 1501.0
Subtracting 862 from 1524 leaves us with 662.
Append the next digit (3) from the dividend to 662 and continue with: 6623 / 862

On to step 8:
When dividing 6623 by 862, we get 7 with a remainder of 589.
Record the quotient 7 as the next digit in the result. 
Result so far: 15017.0
If we take 6034 away from 6623, we end up with 589.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5890, and continue the process.

Let's proceed to step 9:
The number 862 fits into 5890 6 times, leaving a remainder of 718.
The number 6 becomes the next digit in our result. 
Result so far: 15017.6
If we subtract 5172 from 5890, we get 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

Step 10:
If we divide 7180 by 862, we get 8 and a remainder of 284.
Use 8 as the next digit of our solution. 
Result so far: 15017.68
Subtract 6896 from 7180 to get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Let's proceed to step 11:
If we divide 2840 by 862, we get 3 and a remainder of 254.
Write down 3 as next digit of the result. 
Result so far: 15017.683
If we take 2586 away from 2840, we end up with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Going ahead to step 12:
When dividing 2540 by 862, we get 2 with a remainder of 816.
Record the quotient 2 as the next digit in the result. 
Result so far: 15017.6832
If we take 1724 away from 2540, we end up with 816.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

On to step 13:
The number 862 fits into 8160 9 times, leaving a remainder of 402.
Use 9 as the next digit of our solution. 
Result so far: 15017.68329
The remainder is 402 after subtracting 7758 from 8160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Step 14:
When dividing 4020 by 862, we get 4 with a remainder of 572.
Record the quotient 4 as the next digit in the result. 
Result so far: 15017.683294
Subtracting 3448 from 4020 leaves us with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

On to step 15:
When dividing 5720 by 862, we get 6 with a remainder of 548.
Write down 6 as next digit of the result. 
Result so far: 15017.6832946
If we subtract 5172 from 5720, we get 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Step 16:
When dividing 5480 by 862, we get 6 with a remainder of 308.
Record the quotient 6 as the next digit in the result. 
Result so far: 15017.68329466
Subtract 5172 from 5480 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Our division results in 15017.68329466 with a remaining 3.08e-07.
