We're dividing 456185 by 86 
Our goal is to divide 456185 by 86.

Step 1:
86 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 86

Advancing to step 2:
If we divide 45 by 86, we get 0 and a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Fetch the next digit (6) from the dividend, attach it to 45 and continue: 456 / 86

Going ahead to step 3:
When dividing 456 by 86, we get 5 with a remainder of 26.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 430 from 456 to get 26.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 86

Moving on to step 4:
86 goes into 261 3 times with a remainder of 3.
The next digit of our result is 3. 
Result so far: 53.0
Subtracting 258 from 261 leaves us with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 86

On to step 5:
86 can be fit into 38 0 times, resulting in a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 530.0
Deduct 0 from 38 and we're left with 38.
Fetch the next digit (5) from the dividend, attach it to 38 and continue: 385 / 86

Advancing to step 6:
The number 86 fits into 385 4 times, leaving a remainder of 41.
Record the quotient 4 as the next digit in the result. 
Result so far: 5304.0
Deduct 344 from 385 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 7:
86 goes into 410 4 times with a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 5304.4
The remainder is 66 after subtracting 344 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 8:
The number 86 fits into 660 7 times, leaving a remainder of 58.
The next digit of our result is 7. 
Result so far: 5304.47
If we take 602 away from 660, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 9:
86 can be fit into 580 6 times, resulting in a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 5304.476
Subtracting 516 from 580 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 10:
The number 86 fits into 640 7 times, leaving a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 5304.4767
Deduct 602 from 640 and we're left 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.

On to step 11:
86 goes into 380 4 times with a remainder of 36.
The next digit of our result is 4. 
Result so far: 5304.47674
If we subtract 344 from 380, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 12:
86 goes into 360 4 times with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 5304.476744
The remainder is 16 after subtracting 344 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 5304.476744, with a leftover of 1.6e-06.
