386509 divided by 89 
We want to figure out the number of times 386509 can be divided by 89.

Going ahead to step 1:
3 divided by 89 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 89

On to step 2:
89 can be fit into 38 0 times, resulting in a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Take the next digit (6) from the dividend and append it to 38, then repeat: 386 / 89

Moving on to step 3:
When dividing 386 by 89, we get 4 with a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 356 from 386 to get 30.
Append the next digit (5) from the dividend to 30 and continue with: 305 / 89

Let's proceed to step 4:
When dividing 305 by 89, we get 3 with a remainder of 38.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Deduct 267 from 305 and we're left with 38.
Grab the next digit (0) from the dividend, add it to 38, then carry on: 380 / 89

Going ahead to step 5:
380 divided by 89 is 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 434.0
If we subtract 356 from 380, we get 24.
Include the next digit (9) from the dividend after 24, then repeat: 249 / 89

Moving on to step 6:
89 can be fit into 249 2 times, resulting in a remainder of 71.
Put 2 as the next digit of the answer. 
Result so far: 4342.0
If we subtract 178 from 249, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 7:
89 can be fit into 710 7 times, resulting in a remainder of 87.
Write down 7 as next digit of the result. 
Result so far: 4342.7
The remainder is 87 after subtracting 623 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 8:
89 goes into 870 9 times with a remainder of 69.
The number 9 becomes the next digit in our result. 
Result so far: 4342.79
Subtract 801 from 870 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 9:
When dividing 690 by 89, we get 7 with a remainder of 67.
Write down 7 as next digit of the result. 
Result so far: 4342.797
Subtracting 623 from 690 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 10:
89 can be fit into 670 7 times, resulting in a remainder of 47.
Put 7 as the next digit of the answer. 
Result so far: 4342.7977
If we take 623 away from 670, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The final result is 4342.7977 with a remainder of 0.00047.
