Let's divide 900394 by 42
Our goal is to divide 900394 by 42.

Step 1:
When dividing 9 by 42, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 42

Moving on to step 2:
If we divide 90 by 42, we get 2 and a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 6 after subtracting 84 from 90.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 42

Step 3:
When dividing 60 by 42, we get 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtract 42 from 60 to get 18.
Take the next digit (3) from the dividend and append it to 18, then repeat: 183 / 42

Going ahead to step 4:
183 divided by 42 is 4 with a remainder of 15.
The next digit of our result is 4. 
Result so far: 214.0
Deduct 168 from 183 and we're left with 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 42

Moving on to step 5:
42 can be fit into 159 3 times, resulting in a remainder of 33.
The next digit of our result is 3. 
Result so far: 2143.0
The remainder is 33 after subtracting 126 from 159.
Append the next digit (4) from the dividend to 33 and continue with: 334 / 42

Advancing to step 6:
The number 42 fits into 334 7 times, leaving a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 21437.0
Subtracting 294 from 334 leaves us 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.

On to step 7:
The number 42 fits into 400 9 times, leaving a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 21437.9
Deduct 378 from 400 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 8:
When dividing 220 by 42, we get 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 21437.95
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.

Advancing to step 9:
When dividing 100 by 42, we get 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 21437.952
Subtract 84 from 100 to get 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 10:
42 goes into 160 3 times with a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 21437.9523
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.

Going ahead to step 11:
If we divide 340 by 42, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 21437.95238
If we subtract 336 from 340, we 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 12:
If we divide 40 by 42, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 21437.95238
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.

Let's proceed to step 13:
If we divide 400 by 42, we get 9 and a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 21437.9523809
If we subtract 378 from 400, we 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.

On to step 14:
When dividing 220 by 42, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 21437.95238095
Deduct 210 from 220 and we're left 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.

In conclusion, the division gives 21437.95238095 with a balance of 1e-08.
