266021 ÷ 48 
We want to figure out the number of times 266021 can be divided by 48.

On to step 1:
48 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 48

Step 2:
If we divide 26 by 48, we get 0 and a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 26, we get 26.
Append the next digit (6) from the dividend to 26 and continue with: 266 / 48

Moving on to step 3:
The number 48 fits into 266 5 times, leaving a remainder of 26.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 26 after subtracting 240 from 266.
Take the next digit (0) from the dividend and append it to 26, then repeat: 260 / 48

On to step 4:
The number 48 fits into 260 5 times, leaving a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
Subtract 240 from 260 to get 20.
Take the next digit (2) from the dividend and append it to 20, then repeat: 202 / 48

Going ahead to step 5:
When dividing 202 by 48, we get 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 554.0
The remainder is 10 after subtracting 192 from 202.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 48

On to step 6:
101 divided by 48 is 2 with a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 5542.0
Subtract 96 from 101 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
When dividing 50 by 48, we get 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 5542.1
Subtract 48 from 50 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
The number 48 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 5542.1
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
48 goes into 200 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 5542.104
The remainder is 8 after subtracting 192 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
The number 48 fits into 80 1 times, leaving a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 5542.1041
If we subtract 48 from 80, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 11:
48 goes into 320 6 times with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 5542.10416
The remainder is 32 after subtracting 288 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 12:
The number 48 fits into 320 6 times, leaving a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 5542.104166
Subtract 288 from 320 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 5542.104166 with a remaining 3.2e-06.
