366859 ÷ 86 
We want to figure out the number of times 366859 can be divided by 86.

Advancing to step 1:
86 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 86

On to step 2:
36 divided by 86 is 0 with a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 36, we end up with 36.
Include the next digit (6) from the dividend after 36, then repeat: 366 / 86

Going ahead to step 3:
366 divided by 86 is 4 with a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 344 from 366 to get 22.
Fetch the next digit (8) from the dividend, attach it to 22 and continue: 228 / 86

On to step 4:
86 can be fit into 228 2 times, resulting in a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 42.0
If we take 172 away from 228, we end up with 56.
Take the next digit (5) from the dividend and append it to 56, then repeat: 565 / 86

Moving on to step 5:
The number 86 fits into 565 6 times, leaving a remainder of 49.
Use 6 as the next digit of our solution. 
Result so far: 426.0
The remainder is 49 after subtracting 516 from 565.
Include the next digit (9) from the dividend after 49, then repeat: 499 / 86

Let's proceed to step 6:
When dividing 499 by 86, we get 5 with a remainder of 69.
Write down 5 as next digit of the result. 
Result so far: 4265.0
If we take 430 away from 499, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 7:
When dividing 690 by 86, we get 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 4265.8
Subtracting 688 from 690 leaves us 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.

Moving on to step 8:
When dividing 20 by 86, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 4265.8
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
The number 86 fits into 200 2 times, leaving a remainder of 28.
The next digit of our result is 2. 
Result so far: 4265.802
Subtract 172 from 200 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
86 goes into 280 3 times with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 4265.8023
Subtracting 258 from 280 leaves us 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.

Moving on to step 11:
The number 86 fits into 220 2 times, leaving a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 4265.80232
Subtracting 172 from 220 leaves us 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.

Going ahead to step 12:
480 divided by 86 is 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 4265.802325
If we subtract 430 from 480, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 13:
500 divided by 86 is 5 with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 4265.8023255
Subtracting 430 from 500 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 4265.8023255 and a remainder of 7e-07.
