We're dividing 89580158 by 258 
We're looking to find how many times 258 goes into 89580158.

On to step 1:
The number 258 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 258

Advancing to step 2:
89 divided by 258 is 0 with a remainder of 89.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 89, we end up with 89.
Bring next digit (5) of the dividend behind the 89 and repeat the process: 895 / 258

Going ahead to step 3:
258 can be fit into 895 3 times, resulting in a remainder of 121.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 774 from 895 to get 121.
Append the next digit (8) from the dividend to 121 and continue with: 1218 / 258

Moving on to step 4:
When dividing 1218 by 258, we get 4 with a remainder of 186.
Put 4 as the next digit of the answer. 
Result so far: 34.0
Subtract 1032 from 1218 to get 186.
Include the next digit (0) from the dividend after 186, then repeat: 1860 / 258

On to step 5:
If we divide 1860 by 258, we get 7 and a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 347.0
The remainder is 54 after subtracting 1806 from 1860.
Fetch the next digit (1) from the dividend, attach it to 54 and continue: 541 / 258

Going ahead to step 6:
541 divided by 258 is 2 with a remainder of 25.
Record the quotient 2 as the next digit in the result. 
Result so far: 3472.0
Deduct 516 from 541 and we're left with 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 258

Step 7:
The number 258 fits into 255 0 times, leaving a remainder of 255.
Record the quotient 0 as the next digit in the result. 
Result so far: 34720.0
Deduct 0 from 255 and we're left with 255.
Include the next digit (8) from the dividend after 255, then repeat: 2558 / 258

Advancing to step 8:
258 goes into 2558 9 times with a remainder of 236.
The number 9 becomes the next digit in our result. 
Result so far: 347209.0
The remainder is 236 after subtracting 2322 from 2558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Moving on to step 9:
When dividing 2360 by 258, we get 9 with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 347209.9
If we take 2322 away from 2360, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 10:
258 can be fit into 380 1 times, resulting in a remainder of 122.
The next digit of our result is 1. 
Result so far: 347209.91
Subtract 258 from 380 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Step 11:
258 goes into 1220 4 times with a remainder of 188.
Put 4 as the next digit of the answer. 
Result so far: 347209.914
Subtract 1032 from 1220 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 12:
When dividing 1880 by 258, we get 7 with a remainder of 74.
The next digit of our result is 7. 
Result so far: 347209.9147
If we subtract 1806 from 1880, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 13:
The number 258 fits into 740 2 times, leaving a remainder of 224.
Record the quotient 2 as the next digit in the result. 
Result so far: 347209.91472
If we take 516 away from 740, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 14:
The number 258 fits into 2240 8 times, leaving a remainder of 176.
The number 8 becomes the next digit in our result. 
Result so far: 347209.914728
If we subtract 2064 from 2240, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 15:
When dividing 1760 by 258, we get 6 with a remainder of 212.
Use 6 as the next digit of our solution. 
Result so far: 347209.9147286
If we subtract 1548 from 1760, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 16:
258 goes into 2120 8 times with a remainder of 56.
The next digit of our result is 8. 
Result so far: 347209.91472868
Deduct 2064 from 2120 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.

The quotient of the division is 347209.91472868, and the remainder is 5.6e-08.
