We look at the division of 13134396 by 86 
We want to divide 13134396 by 86.

Step 1:
86 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 86

Let's proceed to step 2:
13 divided by 86 is 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 86

Step 3:
86 can be fit into 131 1 times, resulting in a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 86 from 131 and we're left with 45.
Append the next digit (3) from the dividend to 45 and continue with: 453 / 86

Moving on to step 4:
When dividing 453 by 86, we get 5 with a remainder of 23.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 430 from 453, we get 23.
Append the next digit (4) from the dividend to 23 and continue with: 234 / 86

Going ahead to step 5:
When dividing 234 by 86, we get 2 with a remainder of 62.
The next digit of our result is 2. 
Result so far: 152.0
Deduct 172 from 234 and we're left with 62.
Append the next digit (3) from the dividend to 62 and continue with: 623 / 86

Let's proceed to step 6:
623 divided by 86 is 7 with a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 1527.0
Deduct 602 from 623 and we're left with 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 86

Advancing to step 7:
The number 86 fits into 219 2 times, leaving a remainder of 47.
The next digit of our result is 2. 
Result so far: 15272.0
If we subtract 172 from 219, we get 47.
Take the next digit (6) from the dividend and append it to 47, then repeat: 476 / 86

Step 8:
When dividing 476 by 86, we get 5 with a remainder of 46.
Put 5 as the next digit of the answer. 
Result so far: 152725.0
If we take 430 away from 476, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 9:
When dividing 460 by 86, we get 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 152725.5
Deduct 430 from 460 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
86 can be fit into 300 3 times, resulting in a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 152725.53
The remainder is 42 after subtracting 258 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 11:
When dividing 420 by 86, we get 4 with a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 152725.534
Subtract 344 from 420 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 12:
The number 86 fits into 760 8 times, leaving a remainder of 72.
The next digit of our result is 8. 
Result so far: 152725.5348
Subtract 688 from 760 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 13:
86 goes into 720 8 times with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 152725.53488
Subtracting 688 from 720 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 152725.53488 with a balance of 3.2e-05.
