352784 ÷ 86 
Our goal is to divide 352784 by 86.

Advancing 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
Subtracting 0 from 3 leaves us with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 86

Moving on to step 2:
If we divide 35 by 86, we get 0 and a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Append the next digit (2) from the dividend to 35 and continue with: 352 / 86

Going ahead to step 3:
86 goes into 352 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 344 from 352 and we're left with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 86

Going ahead to step 4:
When dividing 87 by 86, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 41.0
Subtracting 86 from 87 leaves us with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 86

Advancing to step 5:
86 can be fit into 18 0 times, resulting in a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 410.0
Subtracting 0 from 18 leaves us with 18.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 86

Going ahead to step 6:
86 can be fit into 184 2 times, resulting in a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 4102.0
If we subtract 172 from 184, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
86 goes into 120 1 times with a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 4102.1
Deduct 86 from 120 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
When dividing 340 by 86, we get 3 with a remainder of 82.
Write down 3 as next digit of the result. 
Result so far: 4102.13
Subtracting 258 from 340 leaves us 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.

Moving on to step 9:
86 goes into 820 9 times with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 4102.139
Subtracting 774 from 820 leaves us 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.

Going ahead to step 10:
If we divide 460 by 86, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 4102.1395
The remainder is 30 after subtracting 430 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
The number 86 fits into 300 3 times, leaving a remainder of 42.
The next digit of our result is 3. 
Result so far: 4102.13953
Subtract 258 from 300 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 12:
When dividing 420 by 86, we get 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 4102.139534
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.

Moving on to step 13:
The number 86 fits into 760 8 times, leaving a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 4102.1395348
Subtract 688 from 760 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 14:
720 divided by 86 is 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 4102.13953488
Subtract 688 from 720 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 4102.13953488 with a remaining 3.2e-08.
