We look at the division of 304057 by 86 
Our goal is to divide 304057 by 86.

Advancing to step 1:
86 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 86

Going ahead to step 2:
When dividing 30 by 86, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Include the next digit (4) from the dividend after 30, then repeat: 304 / 86

Moving on to step 3:
If we divide 304 by 86, we get 3 and a remainder of 46.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 258 from 304, we get 46.
Include the next digit (0) from the dividend after 46, then repeat: 460 / 86

Advancing to step 4:
86 can be fit into 460 5 times, resulting in a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 35.0
If we take 430 away from 460, we end up with 30.
Include the next digit (5) from the dividend after 30, then repeat: 305 / 86

Let's proceed to step 5:
305 divided by 86 is 3 with a remainder of 47.
The next digit of our result is 3. 
Result so far: 353.0
Subtract 258 from 305 to get 47.
Include the next digit (7) from the dividend after 47, then repeat: 477 / 86

Moving on to step 6:
477 divided by 86 is 5 with a remainder of 47.
Put 5 as the next digit of the answer. 
Result so far: 3535.0
If we subtract 430 from 477, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on 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: 3535.5
Subtracting 430 from 470 leaves us 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.

Let's proceed to step 8:
The number 86 fits into 400 4 times, leaving a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 3535.54
If we subtract 344 from 400, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 9:
If we divide 560 by 86, we get 6 and a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 3535.546
Subtracting 516 from 560 leaves us 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.

Step 10:
The number 86 fits into 440 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 3535.5465
If we take 430 away from 440, we end up 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.

Advancing to step 11:
If we divide 100 by 86, we get 1 and a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 3535.54651
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.

Let's proceed to step 12:
86 goes into 140 1 times with a remainder of 54.
The next digit of our result is 1. 
Result so far: 3535.546511
If we take 86 away from 140, we end up 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.

Our division results in 3535.546511 with a remaining 5.4e-06.
