Let's divide 388933 by 86
Let's see how many times 86 fits into 388933.

On to step 1:
When dividing 3 by 86, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 86

On to step 2:
If we divide 38 by 86, we get 0 and a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Grab the next digit (8) from the dividend, add it to 38, then carry on: 388 / 86

Advancing to step 3:
86 goes into 388 4 times with a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 344 away from 388, we end up with 44.
Fetch the next digit (9) from the dividend, attach it to 44 and continue: 449 / 86

Let's proceed to step 4:
The number 86 fits into 449 5 times, leaving a remainder of 19.
The next digit of our result is 5. 
Result so far: 45.0
Subtract 430 from 449 to get 19.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 86

Let's proceed to step 5:
193 divided by 86 is 2 with a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 452.0
If we take 172 away from 193, we end up with 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 86

Step 6:
86 can be fit into 213 2 times, resulting in a remainder of 41.
The next digit of our result is 2. 
Result so far: 4522.0
Subtracting 172 from 213 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 7:
86 can be fit into 410 4 times, resulting in a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 4522.4
Subtract 344 from 410 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 8:
86 can be fit into 660 7 times, resulting in a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 4522.47
Subtract 602 from 660 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 9:
86 goes into 580 6 times with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 4522.476
If we subtract 516 from 580, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 10:
640 divided by 86 is 7 with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 4522.4767
Subtract 602 from 640 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 11:
86 can be fit into 380 4 times, resulting in a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 4522.47674
If we subtract 344 from 380, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 12:
86 goes into 360 4 times with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 4522.476744
Deduct 344 from 360 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 4522.476744 with a remaining 1.6e-06.
