874201 ÷ 51 
The aim is to understand the frequency of 51 in 874201.

Step 1:
51 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 51

Going ahead to step 2:
If we divide 87 by 51, we get 1 and a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 51 from 87 leaves us with 36.
Append the next digit (4) from the dividend to 36 and continue with: 364 / 51

Step 3:
51 goes into 364 7 times with a remainder of 7.
The next digit of our result is 7. 
Result so far: 17.0
Subtracting 357 from 364 leaves us with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 51

On to step 4:
The number 51 fits into 72 1 times, leaving a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 171.0
Subtract 51 from 72 to get 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 51

Step 5:
51 goes into 210 4 times with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 1714.0
The remainder is 6 after subtracting 204 from 210.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 51

Let's proceed to step 6:
If we divide 61 by 51, we get 1 and a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 17141.0
If we take 51 away from 61, 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.

Let's proceed to step 7:
100 divided by 51 is 1 with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 17141.1
If we subtract 51 from 100, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 8:
When dividing 490 by 51, we get 9 with a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 17141.19
Subtract 459 from 490 to get 31.
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 9:
If we divide 310 by 51, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 17141.196
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:
51 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 17141.196
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.

Moving on to step 11:
51 goes into 400 7 times with a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 17141.19607
If we take 357 away from 400, we end up 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.

Advancing to step 12:
430 divided by 51 is 8 with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 17141.196078
If we subtract 408 from 430, we 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.

On to step 13:
220 divided by 51 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 17141.1960784
If we subtract 204 from 220, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
When dividing 160 by 51, we get 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 17141.19607843
If we take 153 away from 160, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

In conclusion, the division gives 17141.19607843 with a balance of 7e-09.
