We divide 642204 by 42
We want to figure out the number of times 642204 can be divided by 42.

Advancing to step 1:
If we divide 6 by 42, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 42

Step 2:
The number 42 fits into 64 1 times, leaving a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 42 from 64 to get 22.
Include the next digit (2) from the dividend after 22, then repeat: 222 / 42

On to step 3:
222 divided by 42 is 5 with a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 210 from 222 leaves us with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 42

Going ahead to step 4:
When dividing 122 by 42, we get 2 with a remainder of 38.
The next digit of our result is 2. 
Result so far: 152.0
If we subtract 84 from 122, we get 38.
Take the next digit (0) from the dividend and append it to 38, then repeat: 380 / 42

Advancing to step 5:
If we divide 380 by 42, we get 9 and a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 1529.0
The remainder is 2 after subtracting 378 from 380.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 42

On to step 6:
42 can be fit into 24 0 times, resulting in a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 15290.0
If we subtract 0 from 24, 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.

Going ahead to step 7:
42 goes into 240 5 times with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 15290.5
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.

Let's proceed to step 8:
The number 42 fits into 300 7 times, leaving a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 15290.57
If we take 294 away from 300, we end up 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 9:
42 can be fit into 60 1 times, resulting in a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 15290.571
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.

On to step 10:
When dividing 180 by 42, we get 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 15290.5714
If we take 168 away from 180, we end up 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:
42 can be fit into 120 2 times, resulting in a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 15290.57142
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 12:
When dividing 360 by 42, we get 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 15290.571428
Subtract 336 from 360 to 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.

Let's proceed to step 13:
The number 42 fits into 240 5 times, leaving a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 15290.5714285
The remainder is 30 after subtracting 210 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
When dividing 300 by 42, we get 7 with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 15290.57142857
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.

The final outcome is 15290.57142857, with a leftover of 6e-09.
