921 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 921

Step 2:
The number 921 fits into 41 0 times, leaving a remainder of 41.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 41 to get 41.
Append the next digit (3) from the dividend to 41 and continue with: 413 / 921

Going ahead to step 3:
921 can be fit into 413 0 times, resulting in a remainder of 413.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 413 after subtracting 0 from 413.
Grab the next digit (9) from the dividend, add it to 413, then carry on: 4139 / 921

Moving on to step 4:
921 goes into 4139 4 times with a remainder of 455.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 3684 from 4139 and we're left with 455.
Append the next digit (0) from the dividend to 455 and continue with: 4550 / 921

Moving on to step 5:
When dividing 4550 by 921, we get 4 with a remainder of 866.
Put 4 as the next digit of the answer. 
Result so far: 44.0
Deduct 3684 from 4550 and we're left with 866.
Take the next digit (0) from the dividend and append it to 866, then repeat: 8660 / 921

Moving on to step 6:
8660 divided by 921 is 9 with a remainder of 371.
The number 9 becomes the next digit in our result. 
Result so far: 449.0
If we take 8289 away from 8660, we end up with 371.
Grab the next digit (2) from the dividend, add it to 371, then carry on: 3712 / 921

Moving on to step 7:
3712 divided by 921 is 4 with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 4494.0
Subtracting 3684 from 3712 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 8:
When dividing 280 by 921, we get 0 with a remainder of 280.
Put 0 as the next digit of the answer. 
Result so far: 4494.0
Subtract 0 from 280 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 9:
If we divide 2800 by 921, we get 3 and a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 4494.03
If we take 2763 away from 2800, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 10:
921 can be fit into 370 0 times, resulting in a remainder of 370.
Write down 0 as next digit of the result. 
Result so far: 4494.03
Deduct 0 from 370 and we're left with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Advancing to step 11:
3700 divided by 921 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 4494.0304
If we subtract 3684 from 3700, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
When dividing 160 by 921, we get 0 with a remainder of 160.
The next digit of our result is 0. 
Result so far: 4494.0304
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 13:
921 can be fit into 1600 1 times, resulting in a remainder of 679.
The number 1 becomes the next digit in our result. 
Result so far: 4494.030401
Deduct 921 from 1600 and we're left with 679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

Moving on to step 14:
921 can be fit into 6790 7 times, resulting in a remainder of 343.
Put 7 as the next digit of the answer. 
Result so far: 4494.0304017
Subtract 6447 from 6790 to get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Going ahead to step 15:
3430 divided by 921 is 3 with a remainder of 667.
Use 3 as the next digit of our solution. 
Result so far: 4494.03040173
If we take 2763 away from 3430, we end up with 667.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6670, and continue the process.

The quotient of the division is 4494.03040173, and the remainder is 6.67e-07.
