Let's divide 656380 by 51
The aim is to understand the frequency of 51 in 656380.

Going ahead to step 1:
The number 51 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 51

Let's proceed to step 2:
65 divided by 51 is 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 51 from 65 and we're left with 14.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 51

Moving on to step 3:
When dividing 146 by 51, we get 2 with a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 44 after subtracting 102 from 146.
Include the next digit (3) from the dividend after 44, then repeat: 443 / 51

Moving on to step 4:
443 divided by 51 is 8 with a remainder of 35.
Put 8 as the next digit of the answer. 
Result so far: 128.0
Subtracting 408 from 443 leaves us with 35.
Bring next digit (8) of the dividend behind the 35 and repeat the process: 358 / 51

On to step 5:
If we divide 358 by 51, we get 7 and a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 1287.0
Subtract 357 from 358 to get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 51

Step 6:
51 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 12870.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
100 divided by 51 is 1 with a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 12870.1
Subtracting 51 from 100 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 8:
51 goes into 490 9 times with a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 12870.19
Deduct 459 from 490 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 9:
51 goes into 310 6 times with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 12870.196
Subtract 306 from 310 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
40 divided by 51 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 12870.196
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
When dividing 400 by 51, we get 7 with a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 12870.19607
The remainder is 43 after subtracting 357 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 12:
430 divided by 51 is 8 with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 12870.196078
Subtracting 408 from 430 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 13:
If we divide 220 by 51, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 12870.1960784
The remainder is 16 after subtracting 204 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
If we divide 160 by 51, we get 3 and a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 12870.19607843
If we subtract 153 from 160, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 12870.19607843 and a remainder of 7e-09.
