We divide 64903916 by 257
The aim is to understand the frequency of 257 in 64903916.

Moving on to step 1:
6 divided by 257 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 257

Step 2:
257 goes into 64 0 times with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Grab the next digit (9) from the dividend, add it to 64, then carry on: 649 / 257

Going ahead to step 3:
If we divide 649 by 257, we get 2 and a remainder of 135.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 135 after subtracting 514 from 649.
Bring next digit (0) of the dividend behind the 135 and repeat the process: 1350 / 257

Advancing to step 4:
When dividing 1350 by 257, we get 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtracting 1285 from 1350 leaves us with 65.
Fetch the next digit (3) from the dividend, attach it to 65 and continue: 653 / 257

Step 5:
257 goes into 653 2 times with a remainder of 139.
Record the quotient 2 as the next digit in the result. 
Result so far: 252.0
If we subtract 514 from 653, we get 139.
Append the next digit (9) from the dividend to 139 and continue with: 1399 / 257

Advancing to step 6:
When dividing 1399 by 257, we get 5 with a remainder of 114.
Put 5 as the next digit of the answer. 
Result so far: 2525.0
Subtracting 1285 from 1399 leaves us with 114.
Bring next digit (1) of the dividend behind the 114 and repeat the process: 1141 / 257

Advancing to step 7:
When dividing 1141 by 257, we get 4 with a remainder of 113.
Record the quotient 4 as the next digit in the result. 
Result so far: 25254.0
The remainder is 113 after subtracting 1028 from 1141.
Fetch the next digit (6) from the dividend, attach it to 113 and continue: 1136 / 257

Step 8:
257 goes into 1136 4 times with a remainder of 108.
Use 4 as the next digit of our solution. 
Result so far: 252544.0
If we take 1028 away from 1136, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 9:
The number 257 fits into 1080 4 times, leaving a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 252544.4
Subtract 1028 from 1080 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 10:
The number 257 fits into 520 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 252544.42
If we take 514 away from 520, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 11:
257 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 252544.42
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 12:
When dividing 600 by 257, we get 2 with a remainder of 86.
Use 2 as the next digit of our solution. 
Result so far: 252544.4202
If we take 514 away from 600, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 13:
If we divide 860 by 257, we get 3 and a remainder of 89.
Record the quotient 3 as the next digit in the result. 
Result so far: 252544.42023
Subtracting 771 from 860 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Going ahead to step 14:
257 goes into 890 3 times with a remainder of 119.
Write down 3 as next digit of the result. 
Result so far: 252544.420233
Subtracting 771 from 890 leaves us with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

After the division, we end up with 252544.420233 and a remainder of 1.19e-05.
