We divide 51061670 by 257
The aim is to understand the frequency of 257 in 51061670.

Going ahead to step 1:
5 divided by 257 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 257

Advancing to step 2:
51 divided by 257 is 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Fetch the next digit (0) from the dividend, attach it to 51 and continue: 510 / 257

Moving on to step 3:
257 goes into 510 1 times with a remainder of 253.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 253 after subtracting 257 from 510.
Include the next digit (6) from the dividend after 253, then repeat: 2536 / 257

On to step 4:
If we divide 2536 by 257, we get 9 and a remainder of 223.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Deduct 2313 from 2536 and we're left with 223.
Include the next digit (1) from the dividend after 223, then repeat: 2231 / 257

Moving on to step 5:
The number 257 fits into 2231 8 times, leaving a remainder of 175.
The next digit of our result is 8. 
Result so far: 198.0
Deduct 2056 from 2231 and we're left with 175.
Take the next digit (6) from the dividend and append it to 175, then repeat: 1756 / 257

Going ahead to step 6:
257 goes into 1756 6 times with a remainder of 214.
The number 6 becomes the next digit in our result. 
Result so far: 1986.0
If we take 1542 away from 1756, we end up with 214.
Bring next digit (7) of the dividend behind the 214 and repeat the process: 2147 / 257

Going ahead to step 7:
When dividing 2147 by 257, we get 8 with a remainder of 91.
Record the quotient 8 as the next digit in the result. 
Result so far: 19868.0
Subtract 2056 from 2147 to get 91.
Append the next digit (0) from the dividend to 91 and continue with: 910 / 257

On to step 8:
If we divide 910 by 257, we get 3 and a remainder of 139.
Put 3 as the next digit of the answer. 
Result so far: 198683.0
The remainder is 139 after subtracting 771 from 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

On to step 9:
When dividing 1390 by 257, we get 5 with a remainder of 105.
Write down 5 as next digit of the result. 
Result so far: 198683.5
Deduct 1285 from 1390 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 10:
If we divide 1050 by 257, we get 4 and a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 198683.54
Subtract 1028 from 1050 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 11:
The number 257 fits into 220 0 times, leaving a remainder of 220.
Write down 0 as next digit of the result. 
Result so far: 198683.54
If we take 0 away from 220, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 12:
2200 divided by 257 is 8 with a remainder of 144.
Use 8 as the next digit of our solution. 
Result so far: 198683.5408
Subtract 2056 from 2200 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 13:
257 can be fit into 1440 5 times, resulting in a remainder of 155.
The number 5 becomes the next digit in our result. 
Result so far: 198683.54085
If we take 1285 away from 1440, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 14:
When dividing 1550 by 257, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 198683.540856
The remainder is 8 after subtracting 1542 from 1550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 15:
257 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 198683.540856
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 16:
The number 257 fits into 800 3 times, leaving a remainder of 29.
The next digit of our result is 3. 
Result so far: 198683.54085603
If we take 771 away from 800, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final outcome is 198683.54085603, with a leftover of 2.9e-08.
