Let's divide 457351 by 42
Let's see how many times 42 fits into 457351.

Step 1:
42 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 42

Let's proceed 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
Subtract 42 from 45 to get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 42

Going ahead to step 3:
If we divide 37 by 42, we get 0 and a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 37 leaves us with 37.
Fetch the next digit (3) from the dividend, attach it to 37 and continue: 373 / 42

On to step 4:
373 divided by 42 is 8 with a remainder of 37.
Write down 8 as next digit of the result. 
Result so far: 108.0
Deduct 336 from 373 and we're left with 37.
Bring next digit (5) of the dividend behind the 37 and repeat the process: 375 / 42

Step 5:
The number 42 fits into 375 8 times, leaving a remainder of 39.
Use 8 as the next digit of our solution. 
Result so far: 1088.0
Subtract 336 from 375 to get 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 42

Moving on to step 6:
42 goes into 391 9 times with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 10889.0
If we subtract 378 from 391, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
If we divide 130 by 42, we get 3 and a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 10889.3
Subtracting 126 from 130 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
40 divided by 42 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 10889.3
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
When dividing 400 by 42, we get 9 with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 10889.309
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 10:
42 goes into 220 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 10889.3095
If we take 210 away from 220, we end up 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.

Going ahead to step 11:
If we divide 100 by 42, we get 2 and a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 10889.30952
Deduct 84 from 100 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
42 can be fit into 160 3 times, resulting in a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 10889.309523
If we subtract 126 from 160, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 13:
When dividing 340 by 42, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 10889.3095238
Subtract 336 from 340 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
40 divided by 42 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 10889.3095238
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 10889.3095238 with a remainder of 4e-08.
