We're dividing 38729501 by 257 
The aim is to understand the frequency of 257 in 38729501.

Let's proceed to step 1:
257 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 257

Step 2:
The number 257 fits into 38 0 times, leaving a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Fetch the next digit (7) from the dividend, attach it to 38 and continue: 387 / 257

Moving on to step 3:
387 divided by 257 is 1 with a remainder of 130.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 130 after subtracting 257 from 387.
Take the next digit (2) from the dividend and append it to 130, then repeat: 1302 / 257

On to step 4:
257 goes into 1302 5 times with a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 1285 from 1302, we get 17.
Bring next digit (9) of the dividend behind the 17 and repeat the process: 179 / 257

Advancing to step 5:
257 goes into 179 0 times with a remainder of 179.
Write down 0 as next digit of the result. 
Result so far: 150.0
The remainder is 179 after subtracting 0 from 179.
Grab the next digit (5) from the dividend, add it to 179, then carry on: 1795 / 257

Going ahead to step 6:
When dividing 1795 by 257, we get 6 with a remainder of 253.
Use 6 as the next digit of our solution. 
Result so far: 1506.0
Subtracting 1542 from 1795 leaves us with 253.
Fetch the next digit (0) from the dividend, attach it to 253 and continue: 2530 / 257

Advancing to step 7:
257 goes into 2530 9 times with a remainder of 217.
The next digit of our result is 9. 
Result so far: 15069.0
Subtract 2313 from 2530 to get 217.
Fetch the next digit (1) from the dividend, attach it to 217 and continue: 2171 / 257

Let's proceed to step 8:
If we divide 2171 by 257, we get 8 and a remainder of 115.
Use 8 as the next digit of our solution. 
Result so far: 150698.0
Subtract 2056 from 2171 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 9:
The number 257 fits into 1150 4 times, leaving a remainder of 122.
The number 4 becomes the next digit in our result. 
Result so far: 150698.4
If we take 1028 away from 1150, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 10:
257 can be fit into 1220 4 times, resulting in a remainder of 192.
Use 4 as the next digit of our solution. 
Result so far: 150698.44
If we subtract 1028 from 1220, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

After the division, we end up with 150698.44 and a remainder of 0.192.
