We're looking to find how many times 586 goes into 86158478.

Advancing to step 1:
The number 586 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 586

Step 2:
The number 586 fits into 86 0 times, leaving a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Append the next digit (1) from the dividend to 86 and continue with: 861 / 586

Moving on to step 3:
If we divide 861 by 586, we get 1 and a remainder of 275.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 586 from 861 to get 275.
Grab the next digit (5) from the dividend, add it to 275, then carry on: 2755 / 586

Let's proceed to step 4:
When dividing 2755 by 586, we get 4 with a remainder of 411.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 411 after subtracting 2344 from 2755.
Grab the next digit (8) from the dividend, add it to 411, then carry on: 4118 / 586

Going ahead to step 5:
4118 divided by 586 is 7 with a remainder of 16.
The next digit of our result is 7. 
Result so far: 147.0
If we take 4102 away from 4118, we end up with 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 586

Going ahead to step 6:
586 can be fit into 164 0 times, resulting in a remainder of 164.
The next digit of our result is 0. 
Result so far: 1470.0
The remainder is 164 after subtracting 0 from 164.
Append the next digit (7) from the dividend to 164 and continue with: 1647 / 586

Going ahead to step 7:
1647 divided by 586 is 2 with a remainder of 475.
Use 2 as the next digit of our solution. 
Result so far: 14702.0
If we take 1172 away from 1647, we end up with 475.
Bring next digit (8) of the dividend behind the 475 and repeat the process: 4758 / 586

On to step 8:
The number 586 fits into 4758 8 times, leaving a remainder of 70.
Record the quotient 8 as the next digit in the result. 
Result so far: 147028.0
The remainder is 70 after subtracting 4688 from 4758.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 9:
586 can be fit into 700 1 times, resulting in a remainder of 114.
The number 1 becomes the next digit in our result. 
Result so far: 147028.1
If we take 586 away from 700, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 10:
The number 586 fits into 1140 1 times, leaving a remainder of 554.
Write down 1 as next digit of the result. 
Result so far: 147028.11
The remainder is 554 after subtracting 586 from 1140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Our division results in 147028.11 with a remaining 0.554.
