21179463 ÷ 48 
We're looking to find how many times 48 goes into 21179463.

Step 1:
48 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 48

Let's proceed to step 2:
If we divide 21 by 48, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 48

Moving on to step 3:
48 can be fit into 211 4 times, resulting in a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 192 from 211, we get 19.
Append the next digit (7) from the dividend to 19 and continue with: 197 / 48

Moving on to step 4:
197 divided by 48 is 4 with a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
Deduct 192 from 197 and we're left with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 48

Going ahead to step 5:
The number 48 fits into 59 1 times, leaving a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 441.0
Deduct 48 from 59 and we're left with 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 48

Let's proceed to step 6:
The number 48 fits into 114 2 times, leaving a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 4412.0
Deduct 96 from 114 and we're left with 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 48

Let's proceed to step 7:
When dividing 186 by 48, we get 3 with a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 44123.0
Subtracting 144 from 186 leaves us with 42.
Bring next digit (3) of the dividend behind the 42 and repeat the process: 423 / 48

Step 8:
The number 48 fits into 423 8 times, leaving a remainder of 39.
Use 8 as the next digit of our solution. 
Result so far: 441238.0
If we subtract 384 from 423, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 9:
When dividing 390 by 48, we get 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 441238.8
The remainder is 6 after subtracting 384 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
48 can be fit into 60 1 times, resulting in a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 441238.81
Deduct 48 from 60 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.

Advancing to step 11:
120 divided by 48 is 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 441238.812
If we subtract 96 from 120, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
If we divide 240 by 48, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 441238.8125
If we take 240 away from 240, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 13:
48 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 441238.8125
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 14:
48 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 441238.8125
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 441238.8125 and a remainder of 0.0.
