We're dividing 20521464 by 921 
The aim is to understand the frequency of 921 in 20521464.

Let's proceed to step 1:
2 divided by 921 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 921

Going ahead to step 2:
20 divided by 921 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 921

Advancing to step 3:
921 can be fit into 205 0 times, resulting in a remainder of 205.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 205 after subtracting 0 from 205.
Take the next digit (2) from the dividend and append it to 205, then repeat: 2052 / 921

Moving on to step 4:
The number 921 fits into 2052 2 times, leaving a remainder of 210.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 1842 away from 2052, we end up with 210.
Include the next digit (1) from the dividend after 210, then repeat: 2101 / 921

Step 5:
921 goes into 2101 2 times with a remainder of 259.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Subtract 1842 from 2101 to get 259.
Grab the next digit (4) from the dividend, add it to 259, then carry on: 2594 / 921

Step 6:
If we divide 2594 by 921, we get 2 and a remainder of 752.
Write down 2 as next digit of the result. 
Result so far: 222.0
The remainder is 752 after subtracting 1842 from 2594.
Include the next digit (6) from the dividend after 752, then repeat: 7526 / 921

On to step 7:
When dividing 7526 by 921, we get 8 with a remainder of 158.
Record the quotient 8 as the next digit in the result. 
Result so far: 2228.0
Deduct 7368 from 7526 and we're left with 158.
Take the next digit (4) from the dividend and append it to 158, then repeat: 1584 / 921

Going ahead to step 8:
The number 921 fits into 1584 1 times, leaving a remainder of 663.
The next digit of our result is 1. 
Result so far: 22281.0
The remainder is 663 after subtracting 921 from 1584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

On to step 9:
921 goes into 6630 7 times with a remainder of 183.
Use 7 as the next digit of our solution. 
Result so far: 22281.7
If we subtract 6447 from 6630, we get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Step 10:
The number 921 fits into 1830 1 times, leaving a remainder of 909.
Record the quotient 1 as the next digit in the result. 
Result so far: 22281.71
The remainder is 909 after subtracting 921 from 1830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9090, and continue the process.

Let's proceed to step 11:
9090 divided by 921 is 9 with a remainder of 801.
Put 9 as the next digit of the answer. 
Result so far: 22281.719
The remainder is 801 after subtracting 8289 from 9090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8010, and continue the process.

Let's proceed to step 12:
921 goes into 8010 8 times with a remainder of 642.
The number 8 becomes the next digit in our result. 
Result so far: 22281.7198
If we take 7368 away from 8010, we end up with 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

Going ahead to step 13:
If we divide 6420 by 921, we get 6 and a remainder of 894.
Record the quotient 6 as the next digit in the result. 
Result so far: 22281.71986
If we take 5526 away from 6420, we end up with 894.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8940, and continue the process.

On to step 14:
921 can be fit into 8940 9 times, resulting in a remainder of 651.
Record the quotient 9 as the next digit in the result. 
Result so far: 22281.719869
If we take 8289 away from 8940, we end up with 651.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6510, and continue the process.

On to step 15:
921 goes into 6510 7 times with a remainder of 63.
Put 7 as the next digit of the answer. 
Result so far: 22281.7198697
The remainder is 63 after subtracting 6447 from 6510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 16:
When dividing 630 by 921, we get 0 with a remainder of 630.
The next digit of our result is 0. 
Result so far: 22281.7198697
If we take 0 away from 630, we end up with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

The quotient of the division is 22281.7198697, and the remainder is 6.3e-07.
