We divide 458600 by 42
We're looking to find how many times 42 goes into 458600.

Advancing to step 1:
4 divided by 42 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 42

Advancing to step 2:
42 can be fit into 45 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 42 from 45 leaves us with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 42

Going ahead to step 3:
If we divide 38 by 42, we get 0 and a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 38, we get 38.
Grab the next digit (6) from the dividend, add it to 38, then carry on: 386 / 42

Let's proceed to step 4:
If we divide 386 by 42, we get 9 and a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 109.0
Subtract 378 from 386 to get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 42

Step 5:
When dividing 80 by 42, we get 1 with a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 1091.0
Subtracting 42 from 80 leaves us with 38.
Bring next digit (0) of the dividend behind the 38 and repeat the process: 380 / 42

Moving on to step 6:
42 goes into 380 9 times with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 10919.0
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
20 divided by 42 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 10919.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
If we divide 200 by 42, we get 4 and a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 10919.04
If we take 168 away from 200, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
320 divided by 42 is 7 with a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 10919.047
Subtract 294 from 320 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 10:
The number 42 fits into 260 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 10919.0476
Subtracting 252 from 260 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
80 divided by 42 is 1 with a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 10919.04761
Subtract 42 from 80 to get 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 12:
When dividing 380 by 42, we get 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 10919.047619
Deduct 378 from 380 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
If we divide 20 by 42, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 10919.047619
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 14:
When dividing 200 by 42, we get 4 with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 10919.04761904
Subtract 168 from 200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 10919.04761904, with a leftover of 3.2e-08.
