We're dividing 860129 by 10 
Our goal is to divide 860129 by 10.

Moving on to step 1:
10 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 10

On to step 2:
If we divide 86 by 10, we get 8 and a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 80 from 86 leaves us with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 10

Step 3:
60 divided by 10 is 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 86.0
The remainder is 0 after subtracting 60 from 60.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 10

Step 4:
The number 10 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 860.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 10

Step 5:
If we divide 12 by 10, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 8601.0
Deduct 10 from 12 and we're left with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 10

Moving on to step 6:
10 goes into 29 2 times with a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 86012.0
The remainder is 9 after subtracting 20 from 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
When dividing 90 by 10, we get 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 86012.9
Deduct 90 from 90 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
10 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 86012.9
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
10 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 86012.9
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 86012.9 and a remainder of 0.0.
