Let's divide 707572 by 51
The aim is to understand the frequency of 51 in 707572.

On to step 1:
If we divide 7 by 51, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 51

Advancing to step 2:
When dividing 70 by 51, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 51 from 70 and we're left with 19.
Append the next digit (7) from the dividend to 19 and continue with: 197 / 51

Moving on to step 3:
51 can be fit into 197 3 times, resulting in a remainder of 44.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 153 from 197 and we're left with 44.
Append the next digit (5) from the dividend to 44 and continue with: 445 / 51

Going ahead to step 4:
51 can be fit into 445 8 times, resulting in a remainder of 37.
The next digit of our result is 8. 
Result so far: 138.0
Subtract 408 from 445 to get 37.
Bring next digit (7) of the dividend behind the 37 and repeat the process: 377 / 51

On to step 5:
When dividing 377 by 51, we get 7 with a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 1387.0
The remainder is 20 after subtracting 357 from 377.
Include the next digit (2) from the dividend after 20, then repeat: 202 / 51

Let's proceed to step 6:
51 can be fit into 202 3 times, resulting in a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 13873.0
If we take 153 away from 202, we end up 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 7:
The number 51 fits into 490 9 times, leaving a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 13873.9
The remainder is 31 after subtracting 459 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 8:
When dividing 310 by 51, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 13873.96
Deduct 306 from 310 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
When dividing 40 by 51, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 13873.96
If we take 0 away from 40, we end up 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 10:
51 can be fit into 400 7 times, resulting in a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 13873.9607
Deduct 357 from 400 and we're left with 43.
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 11:
When dividing 430 by 51, we get 8 with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 13873.96078
If we take 408 away from 430, we end up 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.

Step 12:
If we divide 220 by 51, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 13873.960784
Deduct 204 from 220 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
51 goes into 160 3 times with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 13873.9607843
Subtract 153 from 160 to 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.

Step 14:
51 can be fit into 70 1 times, resulting in a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 13873.96078431
Subtract 51 from 70 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The quotient of the division is 13873.96078431, and the remainder is 1.9e-08.
