9779261 ÷ 921 
The aim is to understand the frequency of 921 in 9779261.

Advancing to step 1:
9 divided by 921 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 921

Moving on to step 2:
921 can be fit into 97 0 times, resulting in a remainder of 97.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 97, we get 97.
Take the next digit (7) from the dividend and append it to 97, then repeat: 977 / 921

Step 3:
921 goes into 977 1 times with a remainder of 56.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 921 from 977 leaves us with 56.
Grab the next digit (9) from the dividend, add it to 56, then carry on: 569 / 921

Step 4:
The number 921 fits into 569 0 times, leaving a remainder of 569.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 569 and we're left with 569.
Bring next digit (2) of the dividend behind the 569 and repeat the process: 5692 / 921

Let's proceed to step 5:
If we divide 5692 by 921, we get 6 and a remainder of 166.
Record the quotient 6 as the next digit in the result. 
Result so far: 106.0
If we take 5526 away from 5692, we end up with 166.
Include the next digit (6) from the dividend after 166, then repeat: 1666 / 921

Moving on to step 6:
1666 divided by 921 is 1 with a remainder of 745.
The number 1 becomes the next digit in our result. 
Result so far: 1061.0
If we subtract 921 from 1666, we get 745.
Grab the next digit (1) from the dividend, add it to 745, then carry on: 7451 / 921

Advancing to step 7:
If we divide 7451 by 921, we get 8 and a remainder of 83.
The number 8 becomes the next digit in our result. 
Result so far: 10618.0
If we subtract 7368 from 7451, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 8:
830 divided by 921 is 0 with a remainder of 830.
The next digit of our result is 0. 
Result so far: 10618.0
Subtract 0 from 830 to get 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

On to step 9:
921 goes into 8300 9 times with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 10618.09
If we take 8289 away from 8300, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 10:
921 goes into 110 0 times with a remainder of 110.
The next digit of our result is 0. 
Result so far: 10618.09
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 11:
When dividing 1100 by 921, we get 1 with a remainder of 179.
Put 1 as the next digit of the answer. 
Result so far: 10618.0901
Subtracting 921 from 1100 leaves us with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Advancing to step 12:
When dividing 1790 by 921, we get 1 with a remainder of 869.
Write down 1 as next digit of the result. 
Result so far: 10618.09011
Deduct 921 from 1790 and we're left with 869.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8690, and continue the process.

Our division results in 10618.09011 with a remaining 0.000869.
