We look at the division of 25596767 by 921 
The aim is to understand the frequency of 921 in 25596767.

Advancing to step 1:
The number 921 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 921

Advancing to step 2:
921 goes into 25 0 times with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Take the next digit (5) from the dividend and append it to 25, then repeat: 255 / 921

Advancing to step 3:
If we divide 255 by 921, we get 0 and a remainder of 255.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 255, we end up with 255.
Fetch the next digit (9) from the dividend, attach it to 255 and continue: 2559 / 921

On to step 4:
2559 divided by 921 is 2 with a remainder of 717.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1842 from 2559 and we're left with 717.
Fetch the next digit (6) from the dividend, attach it to 717 and continue: 7176 / 921

Going ahead to step 5:
If we divide 7176 by 921, we get 7 and a remainder of 729.
Write down 7 as next digit of the result. 
Result so far: 27.0
Subtract 6447 from 7176 to get 729.
Fetch the next digit (7) from the dividend, attach it to 729 and continue: 7297 / 921

Going ahead to step 6:
The number 921 fits into 7297 7 times, leaving a remainder of 850.
The next digit of our result is 7. 
Result so far: 277.0
Subtracting 6447 from 7297 leaves us with 850.
Bring next digit (6) of the dividend behind the 850 and repeat the process: 8506 / 921

Let's proceed to step 7:
If we divide 8506 by 921, we get 9 and a remainder of 217.
Use 9 as the next digit of our solution. 
Result so far: 2779.0
The remainder is 217 after subtracting 8289 from 8506.
Append the next digit (7) from the dividend to 217 and continue with: 2177 / 921

Advancing to step 8:
The number 921 fits into 2177 2 times, leaving a remainder of 335.
Put 2 as the next digit of the answer. 
Result so far: 27792.0
The remainder is 335 after subtracting 1842 from 2177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

On to step 9:
921 goes into 3350 3 times with a remainder of 587.
Write down 3 as next digit of the result. 
Result so far: 27792.3
Subtract 2763 from 3350 to get 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

On to step 10:
921 can be fit into 5870 6 times, resulting in a remainder of 344.
The next digit of our result is 6. 
Result so far: 27792.36
If we take 5526 away from 5870, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

On to step 11:
921 goes into 3440 3 times with a remainder of 677.
The number 3 becomes the next digit in our result. 
Result so far: 27792.363
If we subtract 2763 from 3440, we get 677.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6770, and continue the process.

Advancing to step 12:
921 goes into 6770 7 times with a remainder of 323.
The number 7 becomes the next digit in our result. 
Result so far: 27792.3637
Subtracting 6447 from 6770 leaves us with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Going ahead to step 13:
If we divide 3230 by 921, we get 3 and a remainder of 467.
Put 3 as the next digit of the answer. 
Result so far: 27792.36373
If we take 2763 away from 3230, we end up with 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Going ahead to step 14:
The number 921 fits into 4670 5 times, leaving a remainder of 65.
The next digit of our result is 5. 
Result so far: 27792.363735
Deduct 4605 from 4670 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 15:
The number 921 fits into 650 0 times, leaving a remainder of 650.
Put 0 as the next digit of the answer. 
Result so far: 27792.363735
Subtract 0 from 650 to get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Going ahead to step 16:
If we divide 6500 by 921, we get 7 and a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 27792.36373507
Subtracting 6447 from 6500 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Our division results in 27792.36373507 with a remaining 5.3e-08.
