We look at the division of 29290928 by 657 
The aim is to understand the frequency of 657 in 29290928.

On to step 1:
If we divide 2 by 657, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 657

Advancing to step 2:
657 can be fit into 29 0 times, resulting in a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 29, we end up with 29.
Append the next digit (2) from the dividend to 29 and continue with: 292 / 657

Going ahead to step 3:
The number 657 fits into 292 0 times, leaving a remainder of 292.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 292 to get 292.
Bring next digit (9) of the dividend behind the 292 and repeat the process: 2929 / 657

Step 4:
When dividing 2929 by 657, we get 4 with a remainder of 301.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 2628 away from 2929, we end up with 301.
Fetch the next digit (0) from the dividend, attach it to 301 and continue: 3010 / 657

Advancing to step 5:
The number 657 fits into 3010 4 times, leaving a remainder of 382.
The next digit of our result is 4. 
Result so far: 44.0
If we subtract 2628 from 3010, we get 382.
Grab the next digit (9) from the dividend, add it to 382, then carry on: 3829 / 657

Moving on to step 6:
If we divide 3829 by 657, we get 5 and a remainder of 544.
Use 5 as the next digit of our solution. 
Result so far: 445.0
Subtract 3285 from 3829 to get 544.
Take the next digit (2) from the dividend and append it to 544, then repeat: 5442 / 657

Let's proceed to step 7:
5442 divided by 657 is 8 with a remainder of 186.
The number 8 becomes the next digit in our result. 
Result so far: 4458.0
The remainder is 186 after subtracting 5256 from 5442.
Include the next digit (8) from the dividend after 186, then repeat: 1868 / 657

Advancing to step 8:
1868 divided by 657 is 2 with a remainder of 554.
Record the quotient 2 as the next digit in the result. 
Result so far: 44582.0
If we subtract 1314 from 1868, we get 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Step 9:
657 can be fit into 5540 8 times, resulting in a remainder of 284.
Write down 8 as next digit of the result. 
Result so far: 44582.8
If we subtract 5256 from 5540, we get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 10:
The number 657 fits into 2840 4 times, leaving a remainder of 212.
Use 4 as the next digit of our solution. 
Result so far: 44582.84
Subtracting 2628 from 2840 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Step 11:
If we divide 2120 by 657, we get 3 and a remainder of 149.
Write down 3 as next digit of the result. 
Result so far: 44582.843
Subtract 1971 from 2120 to get 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

On to step 12:
657 goes into 1490 2 times with a remainder of 176.
Use 2 as the next digit of our solution. 
Result so far: 44582.8432
Subtracting 1314 from 1490 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 13:
If we divide 1760 by 657, we get 2 and a remainder of 446.
Put 2 as the next digit of the answer. 
Result so far: 44582.84322
Subtract 1314 from 1760 to get 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

After the division, we end up with 44582.84322 and a remainder of 0.000446.
