Let's divide 384642 by 86
We want to figure out the number of times 384642 can be divided by 86.

On to step 1:
If we divide 3 by 86, we get 0 and 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.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 86

On to step 2:
When dividing 38 by 86, we get 0 with a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Take the next digit (4) from the dividend and append it to 38, then repeat: 384 / 86

Advancing to step 3:
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: 4.0
The remainder is 40 after subtracting 344 from 384.
Fetch the next digit (6) from the dividend, attach it to 40 and continue: 406 / 86

On to step 4:
406 divided by 86 is 4 with a remainder of 62.
Use 4 as the next digit of our solution. 
Result so far: 44.0
The remainder is 62 after subtracting 344 from 406.
Bring next digit (4) of the dividend behind the 62 and repeat the process: 624 / 86

Moving on to step 5:
86 goes into 624 7 times with a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 447.0
If we subtract 602 from 624, we get 22.
Fetch the next digit (2) from the dividend, attach it to 22 and continue: 222 / 86

Moving on to step 6:
222 divided by 86 is 2 with a remainder of 50.
Use 2 as the next digit of our solution. 
Result so far: 4472.0
If we take 172 away from 222, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 7:
500 divided by 86 is 5 with a remainder of 70.
The next digit of our result is 5. 
Result so far: 4472.5
The remainder is 70 after subtracting 430 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 8:
86 can be fit into 700 8 times, resulting in a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 4472.58
Subtracting 688 from 700 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
When dividing 120 by 86, we get 1 with a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 4472.581
If we subtract 86 from 120, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 10:
86 goes into 340 3 times with a remainder of 82.
Record the quotient 3 as the next digit in the result. 
Result so far: 4472.5813
Deduct 258 from 340 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 11:
86 goes into 820 9 times with a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 4472.58139
Deduct 774 from 820 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 12:
When dividing 460 by 86, we get 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 4472.581395
If we take 430 away from 460, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 13:
If we divide 300 by 86, we get 3 and a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 4472.5813953
Deduct 258 from 300 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 14:
420 divided by 86 is 4 with a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 4472.58139534
If we subtract 344 from 420, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Our division results in 4472.58139534 with a remaining 7.6e-08.
