We look at the division of 15140 by 86 
We're looking to find how many times 86 goes into 15140.

On to step 1:
1 divided by 86 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
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 / 86

Step 2:
When dividing 15 by 86, we get 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 86

Let's proceed to step 3:
The number 86 fits into 151 1 times, leaving a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 86 from 151 to get 65.
Append the next digit (4) from the dividend to 65 and continue with: 654 / 86

On to step 4:
86 goes into 654 7 times with a remainder of 52.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we subtract 602 from 654, we get 52.
Append the next digit (0) from the dividend to 52 and continue with: 520 / 86

Moving on to step 5:
If we divide 520 by 86, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 176.0
If we subtract 516 from 520, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 6:
86 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 176.0
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 7:
400 divided by 86 is 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 176.04
Subtract 344 from 400 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 8:
If we divide 560 by 86, we get 6 and a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 176.046
If we subtract 516 from 560, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 9:
The number 86 fits into 440 5 times, leaving a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 176.0465
Deduct 430 from 440 and we're left 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.

Moving on to step 10:
100 divided by 86 is 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 176.04651
Subtracting 86 from 100 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
86 can be fit into 140 1 times, resulting in a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 176.046511
If we take 86 away from 140, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 176.046511 with a remainder of 5.4e-06.
