We look at the division of 13588040 by 85 
Let's see how many times 85 fits into 13588040.

Advancing to step 1:
85 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 85

Step 2:
13 divided by 85 is 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 85

Let's proceed to step 3:
If we divide 135 by 85, we get 1 and a remainder of 50.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 85 from 135 leaves us with 50.
Include the next digit (8) from the dividend after 50, then repeat: 508 / 85

Moving on to step 4:
85 goes into 508 5 times with a remainder of 83.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 425 from 508 leaves us with 83.
Append the next digit (8) from the dividend to 83 and continue with: 838 / 85

Step 5:
85 goes into 838 9 times with a remainder of 73.
The next digit of our result is 9. 
Result so far: 159.0
If we take 765 away from 838, we end up with 73.
Grab the next digit (0) from the dividend, add it to 73, then carry on: 730 / 85

Let's proceed to step 6:
The number 85 fits into 730 8 times, leaving a remainder of 50.
Write down 8 as next digit of the result. 
Result so far: 1598.0
Subtracting 680 from 730 leaves us with 50.
Grab the next digit (4) from the dividend, add it to 50, then carry on: 504 / 85

Step 7:
The number 85 fits into 504 5 times, leaving a remainder of 79.
Record the quotient 5 as the next digit in the result. 
Result so far: 15985.0
Subtracting 425 from 504 leaves us with 79.
Grab the next digit (0) from the dividend, add it to 79, then carry on: 790 / 85

Going ahead to step 8:
85 goes into 790 9 times with a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 159859.0
If we take 765 away from 790, we end up 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.

On to step 9:
85 can be fit into 250 2 times, resulting in a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 159859.2
If we subtract 170 from 250, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
85 goes into 800 9 times with a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 159859.29
If we subtract 765 from 800, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 11:
350 divided by 85 is 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 159859.294
Subtract 340 from 350 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
When dividing 100 by 85, we get 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 159859.2941
If we subtract 85 from 100, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 13:
150 divided by 85 is 1 with a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 159859.29411
The remainder is 65 after subtracting 85 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Our division results in 159859.29411 with a remaining 6.5e-05.
