We look at the division of 862126 by 15 
Our goal is to divide 862126 by 15.

Moving on to step 1:
The number 15 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 15

Moving on to step 2:
15 goes into 86 5 times with a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 75 from 86, we get 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 15

Moving on to step 3:
If we divide 112 by 15, we get 7 and a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 57.0
The remainder is 7 after subtracting 105 from 112.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 15

Step 4:
15 goes into 71 4 times with a remainder of 11.
The next digit of our result is 4. 
Result so far: 574.0
If we subtract 60 from 71, we get 11.
Take the next digit (2) from the dividend and append it to 11, then repeat: 112 / 15

Moving on to step 5:
15 goes into 112 7 times with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 5747.0
Subtracting 105 from 112 leaves us with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 15

Step 6:
15 can be fit into 76 5 times, resulting in a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 57475.0
Subtracting 75 from 76 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
15 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 57475.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
15 can be fit into 100 6 times, resulting in a remainder of 10.
The next digit of our result is 6. 
Result so far: 57475.06
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
15 can be fit into 100 6 times, resulting in a remainder of 10.
The next digit of our result is 6. 
Result so far: 57475.066
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 57475.066 with a remainder of 0.001.
