426213 ÷ 42 
We're looking to find how many times 42 goes into 426213.

Let's proceed to step 1:
If we divide 4 by 42, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 42

Let's proceed to step 2:
42 divided by 42 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 42 from 42 and we're left with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 42

Step 3:
When dividing 6 by 42, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 42

Let's proceed to step 4:
If we divide 62 by 42, we get 1 and a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 101.0
The remainder is 20 after subtracting 42 from 62.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 42

Let's proceed to step 5:
42 goes into 201 4 times with a remainder of 33.
The next digit of our result is 4. 
Result so far: 1014.0
The remainder is 33 after subtracting 168 from 201.
Append the next digit (3) from the dividend to 33 and continue with: 333 / 42

Step 6:
42 can be fit into 333 7 times, resulting in a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 10147.0
Subtracting 294 from 333 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 7:
42 goes into 390 9 times with a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 10147.9
If we take 378 away from 390, we end up 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.

Let's proceed to step 8:
If we divide 120 by 42, we get 2 and a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 10147.92
The remainder is 36 after subtracting 84 from 120.
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 9:
If we divide 360 by 42, we get 8 and a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 10147.928
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.

Advancing to step 10:
42 goes into 240 5 times with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 10147.9285
Subtract 210 from 240 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.

Advancing to step 11:
300 divided by 42 is 7 with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 10147.92857
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.

On to step 12:
The number 42 fits into 60 1 times, leaving a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 10147.928571
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.

Moving on to step 13:
When dividing 180 by 42, we get 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 10147.9285714
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 14:
The number 42 fits into 120 2 times, leaving a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 10147.92857142
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.

In conclusion, the division gives 10147.92857142 with a balance of 3.6e-08.
