65671648 ÷ 921 
Let's see how many times 921 fits into 65671648.

Step 1:
921 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 921

Step 2:
921 goes into 65 0 times with a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Fetch the next digit (6) from the dividend, attach it to 65 and continue: 656 / 921

Moving on to step 3:
If we divide 656 by 921, we get 0 and a remainder of 656.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 656, we get 656.
Take the next digit (7) from the dividend and append it to 656, then repeat: 6567 / 921

Going ahead to step 4:
When dividing 6567 by 921, we get 7 with a remainder of 120.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 6447 from 6567 and we're left with 120.
Fetch the next digit (1) from the dividend, attach it to 120 and continue: 1201 / 921

Step 5:
The number 921 fits into 1201 1 times, leaving a remainder of 280.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
If we subtract 921 from 1201, we get 280.
Fetch the next digit (6) from the dividend, attach it to 280 and continue: 2806 / 921

On to step 6:
2806 divided by 921 is 3 with a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 713.0
The remainder is 43 after subtracting 2763 from 2806.
Include the next digit (4) from the dividend after 43, then repeat: 434 / 921

Step 7:
If we divide 434 by 921, we get 0 and a remainder of 434.
The next digit of our result is 0. 
Result so far: 7130.0
If we take 0 away from 434, we end up with 434.
Append the next digit (8) from the dividend to 434 and continue with: 4348 / 921

Step 8:
921 goes into 4348 4 times with a remainder of 664.
Put 4 as the next digit of the answer. 
Result so far: 71304.0
Deduct 3684 from 4348 and we're left with 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Let's proceed to step 9:
When dividing 6640 by 921, we get 7 with a remainder of 193.
Use 7 as the next digit of our solution. 
Result so far: 71304.7
Subtracting 6447 from 6640 leaves us with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Step 10:
If we divide 1930 by 921, we get 2 and a remainder of 88.
The next digit of our result is 2. 
Result so far: 71304.72
Deduct 1842 from 1930 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 11:
If we divide 880 by 921, we get 0 and a remainder of 880.
Write down 0 as next digit of the result. 
Result so far: 71304.72
Subtract 0 from 880 to get 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8800, and continue the process.

Moving on to step 12:
The number 921 fits into 8800 9 times, leaving a remainder of 511.
Write down 9 as next digit of the result. 
Result so far: 71304.7209
If we subtract 8289 from 8800, we get 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

On to step 13:
921 can be fit into 5110 5 times, resulting in a remainder of 505.
Put 5 as the next digit of the answer. 
Result so far: 71304.72095
If we subtract 4605 from 5110, we get 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Let's proceed to step 14:
When dividing 5050 by 921, we get 5 with a remainder of 445.
Record the quotient 5 as the next digit in the result. 
Result so far: 71304.720955
If we take 4605 away from 5050, we end up with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

In conclusion, the division gives 71304.720955 with a balance of 4.45e-05.
