We look at the division of 420508 by 46 
We're looking to find how many times 46 goes into 420508.

Step 1:
46 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 46

Going ahead to step 2:
The number 46 fits into 42 0 times, leaving a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Fetch the next digit (0) from the dividend, attach it to 42 and continue: 420 / 46

Advancing to step 3:
420 divided by 46 is 9 with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 414 from 420 to get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 46

Going ahead to step 4:
46 goes into 65 1 times with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
The remainder is 19 after subtracting 46 from 65.
Bring next digit (0) of the dividend behind the 19 and repeat the process: 190 / 46

Let's proceed to step 5:
When dividing 190 by 46, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 914.0
Subtract 184 from 190 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 46

On to step 6:
46 can be fit into 68 1 times, resulting in a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 9141.0
Deduct 46 from 68 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 7:
The number 46 fits into 220 4 times, leaving a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 9141.4
Deduct 184 from 220 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.

Step 8:
360 divided by 46 is 7 with a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 9141.47
If we subtract 322 from 360, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
The number 46 fits into 380 8 times, leaving a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 9141.478
Deduct 368 from 380 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.

Step 10:
46 can be fit into 120 2 times, resulting in a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 9141.4782
If we subtract 92 from 120, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
The number 46 fits into 280 6 times, leaving a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 9141.47826
Subtract 276 from 280 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.

On to step 12:
When dividing 40 by 46, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 9141.47826
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.

Going ahead to step 13:
46 goes into 400 8 times with a remainder of 32.
The next digit of our result is 8. 
Result so far: 9141.4782608
The remainder is 32 after subtracting 368 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 14:
46 can be fit into 320 6 times, resulting in a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 9141.47826086
Subtract 276 from 320 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 9141.47826086 with a remainder of 4.4e-08.
