We look at the division of 134671 by 86 
We want to figure out the number of times 134671 can be divided by 86.

Step 1:
When dividing 1 by 86, we get 0 with 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 / 86

Going ahead to step 2:
When dividing 13 by 86, we get 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 86

Going ahead to step 3:
86 goes into 134 1 times with a remainder of 48.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 86 from 134 leaves us with 48.
Bring next digit (6) of the dividend behind the 48 and repeat the process: 486 / 86

Moving on to step 4:
486 divided by 86 is 5 with a remainder of 56.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 430 from 486, we get 56.
Append the next digit (7) from the dividend to 56 and continue with: 567 / 86

Advancing to step 5:
567 divided by 86 is 6 with a remainder of 51.
Put 6 as the next digit of the answer. 
Result so far: 156.0
Subtracting 516 from 567 leaves us with 51.
Grab the next digit (1) from the dividend, add it to 51, then carry on: 511 / 86

Step 6:
If we divide 511 by 86, we get 5 and a remainder of 81.
The number 5 becomes the next digit in our result. 
Result so far: 1565.0
Subtract 430 from 511 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 7:
86 can be fit into 810 9 times, resulting in a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 1565.9
The remainder is 36 after subtracting 774 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 8:
If we divide 360 by 86, we get 4 and a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 1565.94
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.

On to step 9:
86 can be fit into 160 1 times, resulting in a remainder of 74.
Put 1 as the next digit of the answer. 
Result so far: 1565.941
If we subtract 86 from 160, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 10:
The number 86 fits into 740 8 times, leaving a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 1565.9418
Subtract 688 from 740 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 11:
86 goes into 520 6 times with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 1565.94186
Deduct 516 from 520 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
40 divided by 86 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 1565.94186
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 13:
86 goes into 400 4 times with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 1565.9418604
If we take 344 away from 400, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 14:
560 divided by 86 is 6 with a remainder of 44.
The next digit of our result is 6. 
Result so far: 1565.94186046
If we take 516 away from 560, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 1565.94186046 with a remainder of 4.4e-08.
