91762650 divided by 257 
The aim is to understand the frequency of 257 in 91762650.

Going ahead to step 1:
257 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 257

Moving on to step 2:
257 can be fit into 91 0 times, resulting in a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Append the next digit (7) from the dividend to 91 and continue with: 917 / 257

Step 3:
257 goes into 917 3 times with a remainder of 146.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 771 from 917 and we're left with 146.
Take the next digit (6) from the dividend and append it to 146, then repeat: 1466 / 257

Advancing to step 4:
The number 257 fits into 1466 5 times, leaving a remainder of 181.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
The remainder is 181 after subtracting 1285 from 1466.
Append the next digit (2) from the dividend to 181 and continue with: 1812 / 257

Advancing to step 5:
257 goes into 1812 7 times with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 357.0
The remainder is 13 after subtracting 1799 from 1812.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 257

On to step 6:
136 divided by 257 is 0 with a remainder of 136.
Use 0 as the next digit of our solution. 
Result so far: 3570.0
If we subtract 0 from 136, we get 136.
Grab the next digit (5) from the dividend, add it to 136, then carry on: 1365 / 257

Going ahead to step 7:
When dividing 1365 by 257, we get 5 with a remainder of 80.
The next digit of our result is 5. 
Result so far: 35705.0
Subtracting 1285 from 1365 leaves us with 80.
Bring next digit (0) of the dividend behind the 80 and repeat the process: 800 / 257

On to step 8:
257 goes into 800 3 times with a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 357053.0
If we subtract 771 from 800, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 9:
257 can be fit into 290 1 times, resulting in a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 357053.1
Subtracting 257 from 290 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 10:
257 can be fit into 330 1 times, resulting in a remainder of 73.
Use 1 as the next digit of our solution. 
Result so far: 357053.11
If we take 257 away from 330, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

The final result is 357053.11 with a remainder of 0.073.
