We divide 389885 by 86
We want to figure out the number of times 389885 can be divided by 86.

Moving on to step 1:
3 divided by 86 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 86

Moving on to step 2:
86 goes into 38 0 times with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Include the next digit (9) from the dividend after 38, then repeat: 389 / 86

Going ahead to step 3:
The number 86 fits into 389 4 times, leaving a remainder of 45.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 344 away from 389, we end up with 45.
Fetch the next digit (8) from the dividend, attach it to 45 and continue: 458 / 86

Going ahead to step 4:
The number 86 fits into 458 5 times, leaving a remainder of 28.
Put 5 as the next digit of the answer. 
Result so far: 45.0
If we subtract 430 from 458, we get 28.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 86

Advancing to step 5:
86 goes into 288 3 times with a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 453.0
Subtracting 258 from 288 leaves us with 30.
Fetch the next digit (5) from the dividend, attach it to 30 and continue: 305 / 86

On to step 6:
When dividing 305 by 86, we get 3 with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 4533.0
Subtracting 258 from 305 leaves us 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.

Advancing to step 7:
86 goes into 470 5 times with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 4533.5
Deduct 430 from 470 and we're left 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.

Going ahead to step 8:
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: 4533.54
The remainder is 56 after subtracting 344 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
The number 86 fits into 560 6 times, leaving a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 4533.546
Subtract 516 from 560 to get 44.
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 10:
The number 86 fits into 440 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 4533.5465
The remainder is 10 after subtracting 430 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
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: 4533.54651
Subtracting 86 from 100 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 12:
140 divided by 86 is 1 with a remainder of 54.
The next digit of our result is 1. 
Result so far: 4533.546511
The remainder is 54 after subtracting 86 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 4533.546511 and a remainder of 5.4e-06.
