Let's divide 453102 by 42
Let's see how many times 42 fits into 453102.

Going ahead to step 1:
If we divide 4 by 42, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 42

On to step 2:
When dividing 45 by 42, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 42 from 45 and we're left with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 42

On to step 3:
The number 42 fits into 33 0 times, leaving a remainder of 33.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 33 leaves us with 33.
Take the next digit (1) from the dividend and append it to 33, then repeat: 331 / 42

Going ahead to step 4:
331 divided by 42 is 7 with a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
Subtracting 294 from 331 leaves us with 37.
Include the next digit (0) from the dividend after 37, then repeat: 370 / 42

Going ahead to step 5:
370 divided by 42 is 8 with a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 1078.0
The remainder is 34 after subtracting 336 from 370.
Fetch the next digit (2) from the dividend, attach it to 34 and continue: 342 / 42

Advancing to step 6:
If we divide 342 by 42, we get 8 and a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 10788.0
Subtracting 336 from 342 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
42 goes into 60 1 times with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 10788.1
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
The number 42 fits into 180 4 times, leaving a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 10788.14
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
42 goes into 120 2 times with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 10788.142
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 10:
When dividing 360 by 42, we get 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 10788.1428
Subtracting 336 from 360 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
240 divided by 42 is 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 10788.14285
If we subtract 210 from 240, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
42 goes into 300 7 times with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 10788.142857
The remainder is 6 after subtracting 294 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
60 divided by 42 is 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 10788.1428571
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 14:
42 can be fit into 180 4 times, resulting in a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 10788.14285714
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 10788.14285714, and the remainder is 1.2e-08.
