Let's divide 542958 by 86
We're looking to find how many times 86 goes into 542958.

Moving on to step 1:
5 divided by 86 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 86

Step 2:
When dividing 54 by 86, we get 0 with a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Fetch the next digit (2) from the dividend, attach it to 54 and continue: 542 / 86

Let's proceed to step 3:
The number 86 fits into 542 6 times, leaving a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 516 from 542, we get 26.
Append the next digit (9) from the dividend to 26 and continue with: 269 / 86

On to step 4:
86 goes into 269 3 times with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
If we take 258 away from 269, we end up with 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 86

Going ahead to step 5:
86 goes into 115 1 times with a remainder of 29.
The next digit of our result is 1. 
Result so far: 631.0
Subtract 86 from 115 to get 29.
Append the next digit (8) from the dividend to 29 and continue with: 298 / 86

Advancing to step 6:
If we divide 298 by 86, we get 3 and a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 6313.0
If we take 258 away from 298, we end up 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.

Step 7:
When dividing 400 by 86, we get 4 with a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 6313.4
Deduct 344 from 400 and we're left with 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 8:
The number 86 fits into 560 6 times, leaving a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 6313.46
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 9:
The number 86 fits into 440 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 6313.465
Subtract 430 from 440 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
100 divided by 86 is 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 6313.4651
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.

Moving on to step 11:
If we divide 140 by 86, we get 1 and a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 6313.46511
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.

After the division, we end up with 6313.46511 and a remainder of 5.4e-05.
