Let's divide 642722 by 42
Our goal is to divide 642722 by 42.

On to step 1:
42 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 42

Going ahead to step 2:
64 divided by 42 is 1 with 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.
Append the next digit (2) from the dividend to 22 and continue with: 222 / 42

Going ahead to step 3:
When dividing 222 by 42, we get 5 with a remainder of 12.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtract 210 from 222 to get 12.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 42

On to step 4:
The number 42 fits into 127 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 153.0
Deduct 126 from 127 and we're left with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 42

Step 5:
The number 42 fits into 12 0 times, leaving a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 1530.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 42

Let's proceed to step 6:
42 goes into 122 2 times with a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 15302.0
Subtract 84 from 122 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 7:
42 can be fit into 380 9 times, resulting in a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 15302.9
If we take 378 away from 380, 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.

Going ahead to step 8:
20 divided by 42 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 15302.9
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.

Advancing to step 9:
42 goes into 200 4 times with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 15302.904
Subtract 168 from 200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
When dividing 320 by 42, we get 7 with a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 15302.9047
If we take 294 away from 320, we end up with 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 11:
If we divide 260 by 42, we get 6 and a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 15302.90476
If we take 252 away from 260, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
If we divide 80 by 42, we get 1 and a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 15302.904761
Subtracting 42 from 80 leaves us 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.

Let's proceed to step 13:
42 goes into 380 9 times with a remainder of 2.
The next digit of our result is 9. 
Result so far: 15302.9047619
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 14:
42 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 15302.9047619
If we subtract 0 from 20, we 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.

In conclusion, the division gives 15302.9047619 with a balance of 2e-08.
