840102 divided by 85 
Our goal is to divide 840102 by 85.

Moving on to step 1:
85 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 85

Let's proceed to step 2:
84 divided by 85 is 0 with a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Append the next digit (0) from the dividend to 84 and continue with: 840 / 85

On to step 3:
When dividing 840 by 85, we get 9 with a remainder of 75.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 765 from 840, we get 75.
Take the next digit (1) from the dividend and append it to 75, then repeat: 751 / 85

Let's proceed to step 4:
751 divided by 85 is 8 with a remainder of 71.
Write down 8 as next digit of the result. 
Result so far: 98.0
The remainder is 71 after subtracting 680 from 751.
Fetch the next digit (0) from the dividend, attach it to 71 and continue: 710 / 85

Moving on to step 5:
When dividing 710 by 85, we get 8 with a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 988.0
If we subtract 680 from 710, we get 30.
Grab the next digit (2) from the dividend, add it to 30, then carry on: 302 / 85

Going ahead to step 6:
When dividing 302 by 85, we get 3 with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 9883.0
If we take 255 away from 302, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 7:
85 can be fit into 470 5 times, resulting in a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 9883.5
The remainder is 45 after subtracting 425 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 8:
When dividing 450 by 85, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 9883.55
The remainder is 25 after subtracting 425 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 9883.55, with a leftover of 0.025.
