We look at the division of 852139 by 9 
Let's see how many times 9 fits into 852139.

Advancing to step 1:
The number 9 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 9

Advancing to step 2:
If we divide 85 by 9, we get 9 and a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 81 from 85, we get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 9

On to step 3:
If we divide 42 by 9, we get 4 and a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 94.0
If we subtract 36 from 42, we get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 9

Let's proceed to step 4:
9 goes into 61 6 times with a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 946.0
Subtracting 54 from 61 leaves us with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 9

Let's proceed to step 5:
When dividing 73 by 9, we get 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 9468.0
Subtract 72 from 73 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 9

Going ahead to step 6:
9 goes into 19 2 times with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 94682.0
The remainder is 1 after subtracting 18 from 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
10 divided by 9 is 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 94682.1
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 8:
The number 9 fits into 10 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 94682.11
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 94682.11, and the remainder is 0.001.
