63365623 ÷ 257 
The aim is to understand the frequency of 257 in 63365623.

Step 1:
If we divide 6 by 257, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 257

Advancing to step 2:
257 goes into 63 0 times with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Append the next digit (3) from the dividend to 63 and continue with: 633 / 257

Moving on to step 3:
The number 257 fits into 633 2 times, leaving a remainder of 119.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 119 after subtracting 514 from 633.
Include the next digit (6) from the dividend after 119, then repeat: 1196 / 257

Going ahead to step 4:
257 goes into 1196 4 times with a remainder of 168.
Put 4 as the next digit of the answer. 
Result so far: 24.0
The remainder is 168 after subtracting 1028 from 1196.
Append the next digit (5) from the dividend to 168 and continue with: 1685 / 257

Moving on to step 5:
The number 257 fits into 1685 6 times, leaving a remainder of 143.
Record the quotient 6 as the next digit in the result. 
Result so far: 246.0
Subtract 1542 from 1685 to get 143.
Include the next digit (6) from the dividend after 143, then repeat: 1436 / 257

On to step 6:
The number 257 fits into 1436 5 times, leaving a remainder of 151.
Put 5 as the next digit of the answer. 
Result so far: 2465.0
If we subtract 1285 from 1436, we get 151.
Take the next digit (2) from the dividend and append it to 151, then repeat: 1512 / 257

Going ahead to step 7:
When dividing 1512 by 257, we get 5 with a remainder of 227.
Record the quotient 5 as the next digit in the result. 
Result so far: 24655.0
Subtracting 1285 from 1512 leaves us with 227.
Append the next digit (3) from the dividend to 227 and continue with: 2273 / 257

Step 8:
When dividing 2273 by 257, we get 8 with a remainder of 217.
Record the quotient 8 as the next digit in the result. 
Result so far: 246558.0
The remainder is 217 after subtracting 2056 from 2273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Moving on to step 9:
2170 divided by 257 is 8 with a remainder of 114.
Put 8 as the next digit of the answer. 
Result so far: 246558.8
Deduct 2056 from 2170 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 10:
When dividing 1140 by 257, we get 4 with a remainder of 112.
Put 4 as the next digit of the answer. 
Result so far: 246558.84
If we take 1028 away from 1140, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 11:
257 can be fit into 1120 4 times, resulting in a remainder of 92.
Record the quotient 4 as the next digit in the result. 
Result so far: 246558.844
If we take 1028 away from 1120, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

After the division, we end up with 246558.844 and a remainder of 0.0092.
