66358 ÷ 45 
Let's see how many times 45 fits into 66358.

On to step 1:
If we divide 6 by 45, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 45

Step 2:
When dividing 66 by 45, we get 1 with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 45 from 66 and we're left with 21.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 45

Going ahead to step 3:
If we divide 213 by 45, we get 4 and a remainder of 33.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 180 from 213 and we're left with 33.
Grab the next digit (5) from the dividend, add it to 33, then carry on: 335 / 45

Let's proceed to step 4:
When dividing 335 by 45, we get 7 with a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 147.0
Deduct 315 from 335 and we're left with 20.
Take the next digit (8) from the dividend and append it to 20, then repeat: 208 / 45

Going ahead to step 5:
45 can be fit into 208 4 times, resulting in a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 1474.0
If we subtract 180 from 208, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 6:
280 divided by 45 is 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 1474.6
Subtracting 270 from 280 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.

On to step 7:
When dividing 100 by 45, we get 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 1474.62
Subtracting 90 from 100 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.

Step 8:
100 divided by 45 is 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 1474.622
Deduct 90 from 100 and we're left 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.

The final outcome is 1474.622, with a leftover of 0.001.
