We divide 13970 by 86
Let's see how many times 86 fits into 13970.

Let's proceed to step 1:
When dividing 1 by 86, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 86

On to step 2:
When dividing 13 by 86, we get 0 with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 86

Moving on to step 3:
86 can be fit into 139 1 times, resulting in a remainder of 53.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 86 from 139 leaves us with 53.
Fetch the next digit (7) from the dividend, attach it to 53 and continue: 537 / 86

Let's proceed to step 4:
If we divide 537 by 86, we get 6 and a remainder of 21.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtracting 516 from 537 leaves us with 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 86

Step 5:
When dividing 210 by 86, we get 2 with a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 162.0
Subtracting 172 from 210 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 6:
86 goes into 380 4 times with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 162.4
Subtracting 344 from 380 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 7:
360 divided by 86 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 162.44
Subtract 344 from 360 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 162.44 with a remaining 0.016.
