558143 ÷ 86 
We want to divide 558143 by 86.

Step 1:
The number 86 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 86

On to step 2:
86 can be fit into 55 0 times, resulting in a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Bring next digit (8) of the dividend behind the 55 and repeat the process: 558 / 86

Step 3:
86 goes into 558 6 times with a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 516 away from 558, we end up with 42.
Bring next digit (1) of the dividend behind the 42 and repeat the process: 421 / 86

Advancing to step 4:
If we divide 421 by 86, we get 4 and a remainder of 77.
Use 4 as the next digit of our solution. 
Result so far: 64.0
Subtracting 344 from 421 leaves us with 77.
Include the next digit (4) from the dividend after 77, then repeat: 774 / 86

Moving on to step 5:
86 goes into 774 9 times with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 649.0
Deduct 774 from 774 and we're left with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 86

Let's proceed to step 6:
If we divide 3 by 86, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 6490.0
The remainder is 3 after subtracting 0 from 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
86 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 6490.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
If we divide 300 by 86, we get 3 and a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 6490.03
If we subtract 258 from 300, we 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.

Going ahead to step 9:
The number 86 fits into 420 4 times, leaving a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 6490.034
Subtracting 344 from 420 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 10:
The number 86 fits into 760 8 times, leaving a remainder of 72.
The next digit of our result is 8. 
Result so far: 6490.0348
If we take 688 away from 760, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 11:
If we divide 720 by 86, we get 8 and a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 6490.03488
Deduct 688 from 720 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 6490.03488, and the remainder is 3.2e-05.
