248445 ÷ 66 
Let's see how many times 66 fits into 248445.

Step 1:
If we divide 2 by 66, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 66

Advancing to step 2:
66 can be fit into 24 0 times, resulting in a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 24, we get 24.
Include the next digit (8) from the dividend after 24, then repeat: 248 / 66

Step 3:
The number 66 fits into 248 3 times, leaving a remainder of 50.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 198 from 248, we get 50.
Bring next digit (4) of the dividend behind the 50 and repeat the process: 504 / 66

Step 4:
When dividing 504 by 66, we get 7 with a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 37.0
Subtract 462 from 504 to get 42.
Bring next digit (4) of the dividend behind the 42 and repeat the process: 424 / 66

Going ahead to step 5:
66 can be fit into 424 6 times, resulting in a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 376.0
The remainder is 28 after subtracting 396 from 424.
Fetch the next digit (5) from the dividend, attach it to 28 and continue: 285 / 66

Step 6:
66 goes into 285 4 times with a remainder of 21.
Use 4 as the next digit of our solution. 
Result so far: 3764.0
The remainder is 21 after subtracting 264 from 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
If we divide 210 by 66, we get 3 and a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 3764.3
If we take 198 away from 210, we end up 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 8:
66 goes into 120 1 times with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 3764.31
Deduct 66 from 120 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 9:
540 divided by 66 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 3764.318
If we subtract 528 from 540, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
When dividing 120 by 66, we get 1 with a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 3764.3181
Subtract 66 from 120 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 11:
The number 66 fits into 540 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 3764.31818
Subtracting 528 from 540 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.

Going ahead to step 12:
The number 66 fits into 120 1 times, leaving a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 3764.318181
The remainder is 54 after subtracting 66 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 13:
The number 66 fits into 540 8 times, leaving a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 3764.3181818
Subtract 528 from 540 to get 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 14:
The number 66 fits into 120 1 times, leaving a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 3764.31818181
If we take 66 away from 120, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

In conclusion, the division gives 3764.31818181 with a balance of 5.4e-08.
