We look at the division of 526045 by 51 
The aim is to understand the frequency of 51 in 526045.

On to step 1:
The number 51 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 51

Step 2:
When dividing 52 by 51, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 51 from 52 and we're left with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 51

Advancing to step 3:
The number 51 fits into 16 0 times, leaving a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 16, we get 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 51

Advancing to step 4:
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: 103.0
Subtracting 153 from 160 leaves us with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 51

Going ahead to step 5:
The number 51 fits into 74 1 times, leaving a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1031.0
The remainder is 23 after subtracting 51 from 74.
Include the next digit (5) from the dividend after 23, then repeat: 235 / 51

Step 6:
When dividing 235 by 51, we get 4 with a remainder of 31.
Record the quotient 4 as the next digit in the result. 
Result so far: 10314.0
If we take 204 away from 235, we end up 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.

Step 7:
310 divided by 51 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 10314.6
Subtracting 306 from 310 leaves us 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.

Moving on to step 8:
When dividing 40 by 51, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 10314.6
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 9:
400 divided by 51 is 7 with a remainder of 43.
The next digit of our result is 7. 
Result so far: 10314.607
Subtracting 357 from 400 leaves us 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.

Going ahead to step 10:
430 divided by 51 is 8 with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 10314.6078
Subtract 408 from 430 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.

Let's proceed to step 11:
51 goes into 220 4 times with a remainder of 16.
The next digit of our result is 4. 
Result so far: 10314.60784
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.

Let's proceed to step 12:
When dividing 160 by 51, we get 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 10314.607843
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.

Let's proceed to step 13:
When dividing 70 by 51, we get 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 10314.6078431
If we take 51 away from 70, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 14:
51 can be fit into 190 3 times, resulting in a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 10314.60784313
If we take 153 away from 190, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Our division results in 10314.60784313 with a remaining 3.7e-08.
