448123 ÷ 49 
We want to figure out the number of times 448123 can be divided by 49.

Step 1:
49 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 49

On to step 2:
49 goes into 44 0 times with a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 44 and we're left with 44.
Append the next digit (8) from the dividend to 44 and continue with: 448 / 49

On to step 3:
49 can be fit into 448 9 times, resulting in a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 7 after subtracting 441 from 448.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 49

Going ahead to step 4:
The number 49 fits into 71 1 times, leaving a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 91.0
If we take 49 away from 71, we end up with 22.
Fetch the next digit (2) from the dividend, attach it to 22 and continue: 222 / 49

Advancing to step 5:
49 can be fit into 222 4 times, resulting in a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 914.0
If we take 196 away from 222, we end up with 26.
Fetch the next digit (3) from the dividend, attach it to 26 and continue: 263 / 49

Step 6:
When dividing 263 by 49, we get 5 with a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 9145.0
Subtracting 245 from 263 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
180 divided by 49 is 3 with a remainder of 33.
The next digit of our result is 3. 
Result so far: 9145.3
Subtracting 147 from 180 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 8:
When dividing 330 by 49, we get 6 with a remainder of 36.
The next digit of our result is 6. 
Result so far: 9145.36
If we subtract 294 from 330, we get 36.
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:
The number 49 fits into 360 7 times, leaving a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 9145.367
The remainder is 17 after subtracting 343 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 10:
49 goes into 170 3 times with a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 9145.3673
If we take 147 away from 170, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 11:
49 goes into 230 4 times with a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 9145.36734
The remainder is 34 after subtracting 196 from 230.
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 12:
When dividing 340 by 49, we get 6 with a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 9145.367346
If we take 294 away from 340, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 13:
49 can be fit into 460 9 times, resulting in a remainder of 19.
The next digit of our result is 9. 
Result so far: 9145.3673469
Deduct 441 from 460 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 14:
If we divide 190 by 49, we get 3 and a remainder of 43.
The next digit of our result is 3. 
Result so far: 9145.36734693
Deduct 147 from 190 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

The quotient of the division is 9145.36734693, and the remainder is 4.3e-08.
