454148 ÷ 46 
Our goal is to divide 454148 by 46.

Let's proceed to step 1:
46 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 46

Going ahead to step 2:
If we divide 45 by 46, we get 0 and a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Bring next digit (4) of the dividend behind the 45 and repeat the process: 454 / 46

Step 3:
The number 46 fits into 454 9 times, leaving a remainder of 40.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 414 from 454 and we're left with 40.
Fetch the next digit (1) from the dividend, attach it to 40 and continue: 401 / 46

Advancing to step 4:
401 divided by 46 is 8 with a remainder of 33.
Use 8 as the next digit of our solution. 
Result so far: 98.0
The remainder is 33 after subtracting 368 from 401.
Take the next digit (4) from the dividend and append it to 33, then repeat: 334 / 46

Step 5:
46 goes into 334 7 times with a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 987.0
If we take 322 away from 334, we end up with 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 46

Step 6:
If we divide 128 by 46, we get 2 and a remainder of 36.
The next digit of our result is 2. 
Result so far: 9872.0
Deduct 92 from 128 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.

Moving on to step 7:
360 divided by 46 is 7 with a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 9872.7
The remainder is 38 after subtracting 322 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 8:
When dividing 380 by 46, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 9872.78
Subtracting 368 from 380 leaves us 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.

Moving on to step 9:
46 can be fit into 120 2 times, resulting in a remainder of 28.
The next digit of our result is 2. 
Result so far: 9872.782
Subtracting 92 from 120 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 10:
46 goes into 280 6 times with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 9872.7826
If we take 276 away from 280, we end up with 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 11:
46 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 9872.7826
Subtracting 0 from 40 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.

Step 12:
If we divide 400 by 46, we get 8 and a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 9872.782608
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.

Advancing to step 13:
320 divided by 46 is 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 9872.7826086
Subtracting 276 from 320 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 14:
The number 46 fits into 440 9 times, leaving a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 9872.78260869
Subtracting 414 from 440 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

After the division, we end up with 9872.78260869 and a remainder of 2.6e-08.
