383664 ÷ 86 
Let's see how many times 86 fits into 383664.

Step 1:
The number 86 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 86

Step 2:
86 can be fit into 38 0 times, resulting in a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Include the next digit (3) from the dividend after 38, then repeat: 383 / 86

On to step 3:
383 divided by 86 is 4 with a remainder of 39.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 344 from 383 leaves us with 39.
Append the next digit (6) from the dividend to 39 and continue with: 396 / 86

Let's proceed to step 4:
The number 86 fits into 396 4 times, leaving a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 44.0
If we take 344 away from 396, we end up with 52.
Include the next digit (6) from the dividend after 52, then repeat: 526 / 86

Let's proceed to step 5:
86 goes into 526 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 446.0
If we subtract 516 from 526, we get 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 86

Going ahead to step 6:
The number 86 fits into 104 1 times, leaving a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 4461.0
Subtracting 86 from 104 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
When dividing 180 by 86, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 4461.2
Deduct 172 from 180 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
80 divided by 86 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 4461.2
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 9:
86 goes into 800 9 times with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 4461.209
If we subtract 774 from 800, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 10:
260 divided by 86 is 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 4461.2093
If we take 258 away from 260, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
When dividing 20 by 86, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 4461.2093
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
86 can be fit into 200 2 times, resulting in a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 4461.209302
Deduct 172 from 200 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 13:
86 can be fit into 280 3 times, resulting in a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 4461.2093023
Deduct 258 from 280 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 14:
86 goes into 220 2 times with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 4461.20930232
Deduct 172 from 220 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The quotient of the division is 4461.20930232, and the remainder is 4.8e-08.
