We're dividing 93968920 by 257 
The aim is to understand the frequency of 257 in 93968920.

Advancing to step 1:
9 divided by 257 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 257

Going ahead to step 2:
93 divided by 257 is 0 with a remainder of 93.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 93 and we're left with 93.
Grab the next digit (9) from the dividend, add it to 93, then carry on: 939 / 257

Moving on to step 3:
257 can be fit into 939 3 times, resulting in a remainder of 168.
The next digit of our result is 3. 
Result so far: 3.0
If we take 771 away from 939, we end up with 168.
Fetch the next digit (6) from the dividend, attach it to 168 and continue: 1686 / 257

Moving on to step 4:
The number 257 fits into 1686 6 times, leaving a remainder of 144.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
The remainder is 144 after subtracting 1542 from 1686.
Bring next digit (8) of the dividend behind the 144 and repeat the process: 1448 / 257

Advancing to step 5:
The number 257 fits into 1448 5 times, leaving a remainder of 163.
The next digit of our result is 5. 
Result so far: 365.0
Subtracting 1285 from 1448 leaves us with 163.
Include the next digit (9) from the dividend after 163, then repeat: 1639 / 257

Going ahead to step 6:
When dividing 1639 by 257, we get 6 with a remainder of 97.
Use 6 as the next digit of our solution. 
Result so far: 3656.0
If we take 1542 away from 1639, we end up with 97.
Grab the next digit (2) from the dividend, add it to 97, then carry on: 972 / 257

Going ahead to step 7:
257 goes into 972 3 times with a remainder of 201.
The next digit of our result is 3. 
Result so far: 36563.0
If we subtract 771 from 972, we get 201.
Bring next digit (0) of the dividend behind the 201 and repeat the process: 2010 / 257

Going ahead to step 8:
257 goes into 2010 7 times with a remainder of 211.
Put 7 as the next digit of the answer. 
Result so far: 365637.0
Deduct 1799 from 2010 and we're left with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

On to step 9:
If we divide 2110 by 257, we get 8 and a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 365637.8
If we subtract 2056 from 2110, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 10:
When dividing 540 by 257, we get 2 with a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 365637.82
Deduct 514 from 540 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 11:
When dividing 260 by 257, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 365637.821
If we subtract 257 from 260, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 12:
When dividing 30 by 257, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 365637.821
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 13:
When dividing 300 by 257, we get 1 with a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 365637.82101
Subtract 257 from 300 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 14:
257 can be fit into 430 1 times, resulting in a remainder of 173.
Use 1 as the next digit of our solution. 
Result so far: 365637.821011
Subtracting 257 from 430 leaves us with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

The final outcome is 365637.821011, with a leftover of 1.73e-05.
