153897 divided by 85 
We want to divide 153897 by 85.

Let's proceed to step 1:
The number 85 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 85

Moving on to step 2:
If we divide 15 by 85, we get 0 and a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 85

Step 3:
If we divide 153 by 85, we get 1 and a remainder of 68.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 85 from 153 leaves us with 68.
Fetch the next digit (8) from the dividend, attach it to 68 and continue: 688 / 85

Going ahead to step 4:
688 divided by 85 is 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 680 from 688 and we're left with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 85

Moving on to step 5:
If we divide 89 by 85, we get 1 and a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 181.0
The remainder is 4 after subtracting 85 from 89.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 85

Let's proceed to step 6:
When dividing 47 by 85, we get 0 with a remainder of 47.
Write down 0 as next digit of the result. 
Result so far: 1810.0
Deduct 0 from 47 and we're left 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.

Going ahead to step 7:
The number 85 fits into 470 5 times, leaving a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 1810.5
If we take 425 away from 470, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 8:
450 divided by 85 is 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 1810.55
Deduct 425 from 450 and we're left with 25.
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 1810.55, with a leftover of 0.025.
