We're dividing 14809135 by 870 
We want to figure out the number of times 14809135 can be divided by 870.

On to step 1:
The number 870 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 870

Let's proceed to step 2:
870 can be fit into 14 0 times, resulting in a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 870

Step 3:
If we divide 148 by 870, we get 0 and a remainder of 148.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 148 leaves us with 148.
Bring next digit (0) of the dividend behind the 148 and repeat the process: 1480 / 870

Step 4:
870 goes into 1480 1 times with a remainder of 610.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 870 from 1480, we get 610.
Fetch the next digit (9) from the dividend, attach it to 610 and continue: 6109 / 870

Let's proceed to step 5:
870 goes into 6109 7 times with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Deduct 6090 from 6109 and we're left with 19.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 870

Advancing to step 6:
When dividing 191 by 870, we get 0 with a remainder of 191.
Use 0 as the next digit of our solution. 
Result so far: 170.0
Subtract 0 from 191 to get 191.
Grab the next digit (3) from the dividend, add it to 191, then carry on: 1913 / 870

Step 7:
870 goes into 1913 2 times with a remainder of 173.
Record the quotient 2 as the next digit in the result. 
Result so far: 1702.0
Subtracting 1740 from 1913 leaves us with 173.
Append the next digit (5) from the dividend to 173 and continue with: 1735 / 870

Let's proceed to step 8:
If we divide 1735 by 870, we get 1 and a remainder of 865.
Record the quotient 1 as the next digit in the result. 
Result so far: 17021.0
If we subtract 870 from 1735, we get 865.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8650, and continue the process.

Going ahead to step 9:
8650 divided by 870 is 9 with a remainder of 820.
Write down 9 as next digit of the result. 
Result so far: 17021.9
If we subtract 7830 from 8650, we get 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Let's proceed to step 10:
870 goes into 8200 9 times with a remainder of 370.
The number 9 becomes the next digit in our result. 
Result so far: 17021.99
If we take 7830 away from 8200, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Our division results in 17021.99 with a remaining 0.37.
