We divide 451586 by 42
We want to divide 451586 by 42.

Moving on to step 1:
If we divide 4 by 42, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 42

Moving on to step 2:
42 goes into 45 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 3 after subtracting 42 from 45.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 42

Step 3:
The number 42 fits into 31 0 times, leaving a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 31 after subtracting 0 from 31.
Include the next digit (5) from the dividend after 31, then repeat: 315 / 42

Step 4:
315 divided by 42 is 7 with a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 107.0
The remainder is 21 after subtracting 294 from 315.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 42

Let's proceed to step 5:
When dividing 218 by 42, we get 5 with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 1075.0
Subtract 210 from 218 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 42

On to step 6:
When dividing 86 by 42, we get 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 10752.0
If we take 84 away from 86, we end up 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.

Advancing to step 7:
42 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 10752.0
Subtract 0 from 20 to 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.

On to step 8:
42 can be fit into 200 4 times, resulting in a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 10752.04
Deduct 168 from 200 and we're left 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.

On to step 9:
42 goes into 320 7 times with a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 10752.047
If we subtract 294 from 320, we 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.

Moving on to step 10:
42 can be fit into 260 6 times, resulting in a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 10752.0476
The remainder is 8 after subtracting 252 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
42 goes into 80 1 times with a remainder of 38.
Put 1 as the next digit of the answer. 
Result so far: 10752.04761
Deduct 42 from 80 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 12:
The number 42 fits into 380 9 times, leaving a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 10752.047619
Subtracting 378 from 380 leaves us 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.

Moving on to step 13:
42 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 10752.047619
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 14:
If we divide 200 by 42, we get 4 and a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 10752.04761904
Deduct 168 from 200 and we're left 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.

After the division, we end up with 10752.04761904 and a remainder of 3.2e-08.
