We look at the division of 344572 by 42 
Our goal is to divide 344572 by 42.

Let's proceed to step 1:
When dividing 3 by 42, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 42

Going ahead to step 2:
34 divided by 42 is 0 with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Include the next digit (4) from the dividend after 34, then repeat: 344 / 42

On to step 3:
42 goes into 344 8 times with a remainder of 8.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 336 from 344 and we're left with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 42

Moving on to step 4:
42 can be fit into 85 2 times, resulting in a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
If we take 84 away from 85, we end up with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 42

Let's proceed to step 5:
42 goes into 17 0 times with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 820.0
If we take 0 away from 17, we end up with 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 42

Advancing to step 6:
If we divide 172 by 42, we get 4 and a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 8204.0
Subtract 168 from 172 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.

Advancing to step 7:
The number 42 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 8204.0
If we take 0 away from 40, we end up 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.

Advancing to step 8:
When dividing 400 by 42, we get 9 with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 8204.09
Subtract 378 from 400 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
42 can be fit into 220 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 8204.095
Subtracting 210 from 220 leaves us 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.

On to step 10:
When dividing 100 by 42, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 8204.0952
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.

On to step 11:
160 divided by 42 is 3 with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 8204.09523
Subtract 126 from 160 to 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.

Let's proceed to step 12:
42 can be fit into 340 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 8204.095238
Subtracting 336 from 340 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.

On to step 13:
The number 42 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 8204.095238
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 14:
42 goes into 400 9 times with a remainder of 22.
The next digit of our result is 9. 
Result so far: 8204.09523809
Subtract 378 from 400 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 8204.09523809, with a leftover of 2.2e-08.
