We look at the division of 65994489 by 458 
Our goal is to divide 65994489 by 458.

Step 1:
The number 458 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 458

Moving on to step 2:
The number 458 fits into 65 0 times, leaving a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Grab the next digit (9) from the dividend, add it to 65, then carry on: 659 / 458

Let's proceed to step 3:
659 divided by 458 is 1 with a remainder of 201.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 458 from 659, we get 201.
Bring next digit (9) of the dividend behind the 201 and repeat the process: 2019 / 458

Going ahead to step 4:
458 can be fit into 2019 4 times, resulting in a remainder of 187.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we take 1832 away from 2019, we end up with 187.
Grab the next digit (4) from the dividend, add it to 187, then carry on: 1874 / 458

Advancing to step 5:
458 goes into 1874 4 times with a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 144.0
If we subtract 1832 from 1874, we get 42.
Append the next digit (4) from the dividend to 42 and continue with: 424 / 458

Moving on to step 6:
When dividing 424 by 458, we get 0 with a remainder of 424.
The next digit of our result is 0. 
Result so far: 1440.0
If we subtract 0 from 424, we get 424.
Fetch the next digit (8) from the dividend, attach it to 424 and continue: 4248 / 458

Moving on to step 7:
If we divide 4248 by 458, we get 9 and a remainder of 126.
Record the quotient 9 as the next digit in the result. 
Result so far: 14409.0
If we subtract 4122 from 4248, we get 126.
Bring next digit (9) of the dividend behind the 126 and repeat the process: 1269 / 458

Step 8:
458 can be fit into 1269 2 times, resulting in a remainder of 353.
The next digit of our result is 2. 
Result so far: 144092.0
Subtracting 916 from 1269 leaves us with 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Moving on to step 9:
If we divide 3530 by 458, we get 7 and a remainder of 324.
Use 7 as the next digit of our solution. 
Result so far: 144092.7
Subtracting 3206 from 3530 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Let's proceed to step 10:
458 can be fit into 3240 7 times, resulting in a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 144092.77
Subtracting 3206 from 3240 leaves us 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 144092.77, with a leftover of 0.034.
