We look at the division of 164459 by 86 
We want to divide 164459 by 86.

On to step 1:
If we divide 1 by 86, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 86

Let's proceed to step 2:
86 goes into 16 0 times with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 86

Step 3:
The number 86 fits into 164 1 times, leaving a remainder of 78.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 86 away from 164, we end up with 78.
Fetch the next digit (4) from the dividend, attach it to 78 and continue: 784 / 86

Moving on to step 4:
If we divide 784 by 86, we get 9 and a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtract 774 from 784 to get 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 86

Going ahead to step 5:
The number 86 fits into 105 1 times, leaving a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 191.0
The remainder is 19 after subtracting 86 from 105.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 86

Let's proceed to step 6:
199 divided by 86 is 2 with a remainder of 27.
The next digit of our result is 2. 
Result so far: 1912.0
The remainder is 27 after subtracting 172 from 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 7:
The number 86 fits into 270 3 times, leaving a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 1912.3
If we take 258 away from 270, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
The number 86 fits into 120 1 times, leaving a remainder of 34.
The next digit of our result is 1. 
Result so far: 1912.31
The remainder is 34 after subtracting 86 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 9:
340 divided by 86 is 3 with a remainder of 82.
Use 3 as the next digit of our solution. 
Result so far: 1912.313
The remainder is 82 after subtracting 258 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 10:
820 divided by 86 is 9 with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 1912.3139
If we subtract 774 from 820, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 11:
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: 1912.31395
Subtracting 430 from 460 leaves us 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 12:
86 goes into 300 3 times with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 1912.313953
Subtract 258 from 300 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 13:
86 can be fit into 420 4 times, resulting in a remainder of 76.
The next digit of our result is 4. 
Result so far: 1912.3139534
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.

On to step 14:
86 goes into 760 8 times with a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 1912.31395348
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.

The final result is 1912.31395348 with a remainder of 7.2e-08.
