We look at the division of 948390 by 42 
Let's see how many times 42 fits into 948390.

Advancing to step 1:
42 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 42

Going ahead to step 2:
42 can be fit into 94 2 times, resulting in a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 84 from 94 and we're left with 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 42

Going ahead to step 3:
If we divide 108 by 42, we get 2 and a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Subtracting 84 from 108 leaves us with 24.
Include the next digit (3) from the dividend after 24, then repeat: 243 / 42

Let's proceed to step 4:
If we divide 243 by 42, we get 5 and a remainder of 33.
Record the quotient 5 as the next digit in the result. 
Result so far: 225.0
Deduct 210 from 243 and we're left with 33.
Fetch the next digit (9) from the dividend, attach it to 33 and continue: 339 / 42

Advancing to step 5:
339 divided by 42 is 8 with a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 2258.0
If we subtract 336 from 339, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 42

Going ahead to step 6:
42 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 22580.0
Subtract 0 from 30 to 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 7:
When dividing 300 by 42, we get 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 22580.7
Subtract 294 from 300 to get 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 8:
60 divided by 42 is 1 with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 22580.71
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
42 goes into 180 4 times with a remainder of 12.
The next digit of our result is 4. 
Result so far: 22580.714
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.

Going ahead to step 10:
The number 42 fits into 120 2 times, leaving a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 22580.7142
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.

Going ahead to step 11:
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: 22580.71428
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 12:
When dividing 240 by 42, we get 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 22580.714285
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.

On to step 13:
The number 42 fits into 300 7 times, leaving a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 22580.7142857
Deduct 294 from 300 and we're left 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.

Let's proceed to step 14:
If we divide 60 by 42, we get 1 and a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 22580.71428571
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.

In conclusion, the division gives 22580.71428571 with a balance of 1.8e-08.
