Let's divide 355338 by 42
We want to divide 355338 by 42.

Let's proceed to step 1:
3 divided by 42 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 42

On to step 2:
When dividing 35 by 42, we get 0 with a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Take the next digit (5) from the dividend and append it to 35, then repeat: 355 / 42

Moving on to step 3:
The number 42 fits into 355 8 times, leaving a remainder of 19.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 336 from 355 to get 19.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 42

On to step 4:
42 can be fit into 193 4 times, resulting in a remainder of 25.
Use 4 as the next digit of our solution. 
Result so far: 84.0
Subtract 168 from 193 to get 25.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 42

Advancing to step 5:
253 divided by 42 is 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 846.0
If we take 252 away from 253, we end up with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 42

Step 6:
The number 42 fits into 18 0 times, leaving a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 8460.0
If we subtract 0 from 18, 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 7:
If we divide 180 by 42, we get 4 and a remainder of 12.
The next digit of our result is 4. 
Result so far: 8460.4
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
120 divided by 42 is 2 with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 8460.42
Deduct 84 from 120 and we're left 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 9:
If we divide 360 by 42, we get 8 and a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 8460.428
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.

Moving on to step 10:
240 divided by 42 is 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 8460.4285
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.

Step 11:
When dividing 300 by 42, we get 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 8460.42857
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.

Going ahead to step 12:
60 divided by 42 is 1 with a remainder of 18.
The next digit of our result is 1. 
Result so far: 8460.428571
Deduct 42 from 60 and we're left 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.

Going ahead to step 13:
42 can be fit into 180 4 times, resulting in a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 8460.4285714
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 14:
42 goes into 120 2 times with a remainder of 36.
The next digit of our result is 2. 
Result so far: 8460.42857142
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.

The final result is 8460.42857142 with a remainder of 3.6e-08.
