We look at the division of 48439072 by 451 
We want to figure out the number of times 48439072 can be divided by 451.

Going ahead to step 1:
4 divided by 451 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 451

Let's proceed to step 2:
451 can be fit into 48 0 times, resulting in a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 48 leaves us with 48.
Grab the next digit (4) from the dividend, add it to 48, then carry on: 484 / 451

Moving on to step 3:
484 divided by 451 is 1 with a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 451 from 484 to get 33.
Bring next digit (3) of the dividend behind the 33 and repeat the process: 333 / 451

Advancing to step 4:
If we divide 333 by 451, we get 0 and a remainder of 333.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 333, we end up with 333.
Grab the next digit (9) from the dividend, add it to 333, then carry on: 3339 / 451

Let's proceed to step 5:
451 goes into 3339 7 times with a remainder of 182.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
Deduct 3157 from 3339 and we're left with 182.
Include the next digit (0) from the dividend after 182, then repeat: 1820 / 451

Going ahead to step 6:
The number 451 fits into 1820 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 1074.0
If we subtract 1804 from 1820, we get 16.
Bring next digit (7) of the dividend behind the 16 and repeat the process: 167 / 451

Moving on to step 7:
When dividing 167 by 451, we get 0 with a remainder of 167.
Record the quotient 0 as the next digit in the result. 
Result so far: 10740.0
Subtract 0 from 167 to get 167.
Bring next digit (2) of the dividend behind the 167 and repeat the process: 1672 / 451

On to step 8:
1672 divided by 451 is 3 with a remainder of 319.
Write down 3 as next digit of the result. 
Result so far: 107403.0
Subtract 1353 from 1672 to get 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Step 9:
When dividing 3190 by 451, we get 7 with a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 107403.7
Deduct 3157 from 3190 and we're left 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.

Advancing to step 10:
330 divided by 451 is 0 with a remainder of 330.
The next digit of our result is 0. 
Result so far: 107403.7
If we subtract 0 from 330, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 11:
451 goes into 3300 7 times with a remainder of 143.
The next digit of our result is 7. 
Result so far: 107403.707
Subtracting 3157 from 3300 leaves us with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Moving on to step 12:
451 goes into 1430 3 times with a remainder of 77.
The number 3 becomes the next digit in our result. 
Result so far: 107403.7073
If we subtract 1353 from 1430, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 13:
The number 451 fits into 770 1 times, leaving a remainder of 319.
Record the quotient 1 as the next digit in the result. 
Result so far: 107403.70731
Subtracting 451 from 770 leaves us with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Advancing to step 14:
The number 451 fits into 3190 7 times, leaving a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 107403.707317
If we take 3157 away from 3190, we end up 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 15:
451 can be fit into 330 0 times, resulting in a remainder of 330.
Record the quotient 0 as the next digit in the result. 
Result so far: 107403.707317
The remainder is 330 after subtracting 0 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Step 16:
451 goes into 3300 7 times with a remainder of 143.
Put 7 as the next digit of the answer. 
Result so far: 107403.70731707
Subtract 3157 from 3300 to get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

In conclusion, the division gives 107403.70731707 with a balance of 1.43e-07.
