84580158 ÷ 158 
We want to figure out the number of times 84580158 can be divided by 158.

Step 1:
158 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 158

On to step 2:
84 divided by 158 is 0 with a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Fetch the next digit (5) from the dividend, attach it to 84 and continue: 845 / 158

Moving on to step 3:
845 divided by 158 is 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 790 from 845, we get 55.
Fetch the next digit (8) from the dividend, attach it to 55 and continue: 558 / 158

Step 4:
The number 158 fits into 558 3 times, leaving a remainder of 84.
Put 3 as the next digit of the answer. 
Result so far: 53.0
If we take 474 away from 558, we end up with 84.
Bring next digit (0) of the dividend behind the 84 and repeat the process: 840 / 158

Let's proceed to step 5:
840 divided by 158 is 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 535.0
Deduct 790 from 840 and we're left with 50.
Grab the next digit (1) from the dividend, add it to 50, then carry on: 501 / 158

On to step 6:
501 divided by 158 is 3 with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 5353.0
If we subtract 474 from 501, we get 27.
Append the next digit (5) from the dividend to 27 and continue with: 275 / 158

Moving on to step 7:
The number 158 fits into 275 1 times, leaving a remainder of 117.
Record the quotient 1 as the next digit in the result. 
Result so far: 53531.0
If we take 158 away from 275, we end up with 117.
Append the next digit (8) from the dividend to 117 and continue with: 1178 / 158

Going ahead to step 8:
If we divide 1178 by 158, we get 7 and a remainder of 72.
Record the quotient 7 as the next digit in the result. 
Result so far: 535317.0
Subtracting 1106 from 1178 leaves us 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 9:
If we divide 720 by 158, we get 4 and a remainder of 88.
Use 4 as the next digit of our solution. 
Result so far: 535317.4
The remainder is 88 after subtracting 632 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 10:
The number 158 fits into 880 5 times, leaving a remainder of 90.
The number 5 becomes the next digit in our result. 
Result so far: 535317.45
Subtract 790 from 880 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 11:
158 goes into 900 5 times with a remainder of 110.
The next digit of our result is 5. 
Result so far: 535317.455
Deduct 790 from 900 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

The quotient of the division is 535317.455, and the remainder is 0.011.
