376518 ÷ 86 
We want to divide 376518 by 86.

Step 1:
86 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 86

On to step 2:
37 divided by 86 is 0 with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 37 after subtracting 0 from 37.
Grab the next digit (6) from the dividend, add it to 37, then carry on: 376 / 86

Advancing to step 3:
86 goes into 376 4 times with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 344 from 376 to get 32.
Append the next digit (5) from the dividend to 32 and continue with: 325 / 86

Moving on to step 4:
325 divided by 86 is 3 with a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Subtract 258 from 325 to get 67.
Append the next digit (1) from the dividend to 67 and continue with: 671 / 86

Moving on to step 5:
If we divide 671 by 86, we get 7 and a remainder of 69.
The number 7 becomes the next digit in our result. 
Result so far: 437.0
Subtract 602 from 671 to get 69.
Bring next digit (8) of the dividend behind the 69 and repeat the process: 698 / 86

Going ahead to step 6:
86 goes into 698 8 times with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 4378.0
If we take 688 away from 698, 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.

Going ahead to step 7:
86 can be fit into 100 1 times, resulting in a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 4378.1
Deduct 86 from 100 and we're left with 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 8:
If we divide 140 by 86, we get 1 and a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 4378.11
Subtract 86 from 140 to get 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 4378.11 with a remaining 0.054.
