485443 ÷ 86 
We want to divide 485443 by 86.

Let's proceed to step 1:
The number 86 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 86

Moving on to step 2:
The number 86 fits into 48 0 times, leaving a remainder of 48.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Include the next digit (5) from the dividend after 48, then repeat: 485 / 86

Step 3:
The number 86 fits into 485 5 times, leaving a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 430 from 485 and we're left with 55.
Bring next digit (4) of the dividend behind the 55 and repeat the process: 554 / 86

Advancing to step 4:
86 can be fit into 554 6 times, resulting in a remainder of 38.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
If we subtract 516 from 554, we get 38.
Grab the next digit (4) from the dividend, add it to 38, then carry on: 384 / 86

Step 5:
If we divide 384 by 86, we get 4 and a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 564.0
Subtract 344 from 384 to get 40.
Fetch the next digit (3) from the dividend, attach it to 40 and continue: 403 / 86

Let's proceed to step 6:
86 goes into 403 4 times with a remainder of 59.
The next digit of our result is 4. 
Result so far: 5644.0
Subtracting 344 from 403 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 7:
When dividing 590 by 86, we get 6 with a remainder of 74.
The next digit of our result is 6. 
Result so far: 5644.6
Deduct 516 from 590 and we're left with 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 8:
The number 86 fits into 740 8 times, leaving a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 5644.68
If we take 688 away from 740, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 9:
If we divide 520 by 86, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 5644.686
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.

Advancing to step 10:
If we divide 40 by 86, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 5644.686
Subtracting 0 from 40 leaves us 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.

Step 11:
86 can be fit into 400 4 times, resulting in a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 5644.68604
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.

Let's proceed to step 12:
86 can be fit into 560 6 times, resulting in a remainder of 44.
The next digit of our result is 6. 
Result so far: 5644.686046
The remainder is 44 after subtracting 516 from 560.
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 13:
The number 86 fits into 440 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 5644.6860465
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.

On to step 14:
If we divide 100 by 86, we get 1 and a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 5644.68604651
If we subtract 86 from 100, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 5644.68604651 with a remaining 1.4e-08.
