58603 ÷ 5 
We want to figure out the number of times 58603 can be divided by 5.

On to step 1:
5 can be fit into 5 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 5 from 5 to get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 5

Step 2:
5 can be fit into 8 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 5 from 8, we get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 5

Going ahead to step 3:
If we divide 36 by 5, we get 7 and a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 117.0
Subtracting 35 from 36 leaves us with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 5

Moving on to step 4:
10 divided by 5 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 1172.0
Subtracting 10 from 10 leaves us with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 5

On to step 5:
If we divide 3 by 5, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 11720.0
If we take 0 away from 3, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 6:
5 can be fit into 30 6 times, resulting in a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 11720.6
Subtracting 30 from 30 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
If we divide 0 by 5, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11720.6
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
If we divide 0 by 5, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11720.6
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 11720.6, with a leftover of 0.0.
