We divide 108580 by 42
We want to figure out the number of times 108580 can be divided by 42.

Let's proceed to step 1:
When dividing 1 by 42, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 42

Let's proceed to step 2:
10 divided by 42 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 42

Advancing to step 3:
42 can be fit into 108 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 24 after subtracting 84 from 108.
Include the next digit (5) from the dividend after 24, then repeat: 245 / 42

Moving on to step 4:
42 can be fit into 245 5 times, resulting in a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtracting 210 from 245 leaves us with 35.
Grab the next digit (8) from the dividend, add it to 35, then carry on: 358 / 42

Let's proceed to step 5:
42 can be fit into 358 8 times, resulting in a remainder of 22.
The next digit of our result is 8. 
Result so far: 258.0
Deduct 336 from 358 and we're left with 22.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 42

Moving on to step 6:
220 divided by 42 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 2585.0
Subtracting 210 from 220 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
If we divide 100 by 42, we get 2 and a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 2585.2
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
160 divided by 42 is 3 with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 2585.23
Subtract 126 from 160 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 9:
When dividing 340 by 42, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 2585.238
Subtracting 336 from 340 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
The number 42 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 2585.238
If we take 0 away from 40, 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.

On to step 11:
If we divide 400 by 42, we get 9 and a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 2585.23809
Subtracting 378 from 400 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 12:
220 divided by 42 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 2585.238095
Subtract 210 from 220 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.

Going ahead to step 13:
42 goes into 100 2 times with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 2585.2380952
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
When dividing 160 by 42, we get 3 with a remainder of 34.
The next digit of our result is 3. 
Result so far: 2585.23809523
Deduct 126 from 160 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 2585.23809523, with a leftover of 3.4e-08.
