We divide 338251 by 86
Our goal is to divide 338251 by 86.

Moving on to step 1:
The number 86 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 86

On to step 2:
If we divide 33 by 86, we get 0 and a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 33, we get 33.
Take the next digit (8) from the dividend and append it to 33, then repeat: 338 / 86

Let's proceed to step 3:
The number 86 fits into 338 3 times, leaving a remainder of 80.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 258 away from 338, we end up with 80.
Include the next digit (2) from the dividend after 80, then repeat: 802 / 86

Let's proceed to step 4:
802 divided by 86 is 9 with a remainder of 28.
The next digit of our result is 9. 
Result so far: 39.0
Subtracting 774 from 802 leaves us with 28.
Bring next digit (5) of the dividend behind the 28 and repeat the process: 285 / 86

Moving on to step 5:
86 goes into 285 3 times with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 393.0
If we subtract 258 from 285, we get 27.
Bring next digit (1) of the dividend behind the 27 and repeat the process: 271 / 86

On to step 6:
271 divided by 86 is 3 with a remainder of 13.
The next digit of our result is 3. 
Result so far: 3933.0
The remainder is 13 after subtracting 258 from 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
86 can be fit into 130 1 times, resulting in a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 3933.1
If we take 86 away from 130, we end up with 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 8:
When dividing 440 by 86, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 3933.15
Deduct 430 from 440 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
100 divided by 86 is 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 3933.151
Subtract 86 from 100 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
140 divided by 86 is 1 with a remainder of 54.
The next digit of our result is 1. 
Result so far: 3933.1511
Subtracting 86 from 140 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 3933.1511 with a remainder of 0.00054.
