906349 divided by 42 
Let's see how many times 42 fits into 906349.

Advancing to step 1:
The number 42 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 42

Moving on to step 2:
The number 42 fits into 90 2 times, leaving a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 84 from 90 leaves us with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 42

On to step 3:
The number 42 fits into 66 1 times, leaving a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we take 42 away from 66, we end up with 24.
Include the next digit (3) from the dividend after 24, then repeat: 243 / 42

Let's proceed to step 4:
When dividing 243 by 42, we get 5 with a remainder of 33.
Put 5 as the next digit of the answer. 
Result so far: 215.0
If we take 210 away from 243, we end up with 33.
Include the next digit (4) from the dividend after 33, then repeat: 334 / 42

Let's proceed to step 5:
334 divided by 42 is 7 with a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 2157.0
Subtract 294 from 334 to get 40.
Take the next digit (9) from the dividend and append it to 40, then repeat: 409 / 42

Going ahead to step 6:
42 goes into 409 9 times with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 21579.0
Subtracting 378 from 409 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
310 divided by 42 is 7 with a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 21579.7
Subtract 294 from 310 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.

Let's proceed to step 8:
42 goes into 160 3 times with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 21579.73
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
When dividing 340 by 42, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 21579.738
Subtract 336 from 340 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.

Going ahead to step 10:
42 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 21579.738
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.

Advancing to step 11:
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: 21579.73809
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.

Step 12:
If we divide 220 by 42, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 21579.738095
If we take 210 away from 220, we end up 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 13:
42 goes into 100 2 times with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 21579.7380952
If we subtract 84 from 100, we 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.

Step 14:
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: 21579.73809523
Deduct 126 from 160 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 21579.73809523, with a leftover of 3.4e-08.
