We're dividing 159438 by 85 
We're looking to find how many times 85 goes into 159438.

Moving on to step 1:
If we divide 1 by 85, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 85

Going ahead to step 2:
If we divide 15 by 85, we get 0 and a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 85

Step 3:
85 goes into 159 1 times with a remainder of 74.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 85 from 159 leaves us with 74.
Bring next digit (4) of the dividend behind the 74 and repeat the process: 744 / 85

Going ahead to step 4:
744 divided by 85 is 8 with a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 18.0
Deduct 680 from 744 and we're left with 64.
Grab the next digit (3) from the dividend, add it to 64, then carry on: 643 / 85

On to step 5:
643 divided by 85 is 7 with a remainder of 48.
Record the quotient 7 as the next digit in the result. 
Result so far: 187.0
Subtracting 595 from 643 leaves us with 48.
Grab the next digit (8) from the dividend, add it to 48, then carry on: 488 / 85

Step 6:
The number 85 fits into 488 5 times, leaving a remainder of 63.
Record the quotient 5 as the next digit in the result. 
Result so far: 1875.0
Subtracting 425 from 488 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 7:
If we divide 630 by 85, we get 7 and a remainder of 35.
The number 7 becomes the next digit in our result. 
Result so far: 1875.7
If we take 595 away from 630, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 8:
350 divided by 85 is 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 1875.74
Subtracting 340 from 350 leaves us 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.

Step 9:
85 can be fit into 100 1 times, resulting in a remainder of 15.
The next digit of our result is 1. 
Result so far: 1875.741
Subtracting 85 from 100 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 10:
The number 85 fits into 150 1 times, leaving a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 1875.7411
Subtracting 85 from 150 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final outcome is 1875.7411, with a leftover of 0.00065.
