450180 divided by 42 
The aim is to understand the frequency of 42 in 450180.

Let's proceed to step 1:
If we divide 4 by 42, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 42

On to step 2:
If we divide 45 by 42, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 42 from 45, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 42

Moving on to step 3:
If we divide 30 by 42, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 30 and we're left with 30.
Grab the next digit (1) from the dividend, add it to 30, then carry on: 301 / 42

On to step 4:
If we divide 301 by 42, we get 7 and a remainder of 7.
The next digit of our result is 7. 
Result so far: 107.0
If we subtract 294 from 301, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 42

Let's proceed to step 5:
42 goes into 78 1 times with a remainder of 36.
The next digit of our result is 1. 
Result so far: 1071.0
If we take 42 away from 78, we end up with 36.
Take the next digit (0) from the dividend and append it to 36, then repeat: 360 / 42

Advancing to step 6:
360 divided by 42 is 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 10718.0
If we subtract 336 from 360, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
If we divide 240 by 42, we get 5 and a remainder of 30.
The next digit of our result is 5. 
Result so far: 10718.5
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.

Advancing to step 8:
42 can be fit into 300 7 times, resulting in a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 10718.57
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.

On to step 9:
42 can be fit into 60 1 times, resulting in a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 10718.571
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 10:
When dividing 180 by 42, we get 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 10718.5714
Deduct 168 from 180 and we're left 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.

On to step 11:
When dividing 120 by 42, we get 2 with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 10718.57142
If we subtract 84 from 120, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 12:
42 can be fit into 360 8 times, resulting in a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 10718.571428
If we take 336 away from 360, we end up 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.

Step 13:
42 can be fit into 240 5 times, resulting in a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 10718.5714285
Subtracting 210 from 240 leaves us with 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 14:
If we divide 300 by 42, we get 7 and a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 10718.57142857
Subtracting 294 from 300 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.

The quotient of the division is 10718.57142857, and the remainder is 6e-09.
