526443 ÷ 51 
The aim is to understand the frequency of 51 in 526443.

Going ahead to step 1:
5 divided by 51 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 51

Advancing to step 2:
52 divided by 51 is 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 51 from 52 leaves us with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 51

Going ahead to step 3:
When dividing 16 by 51, we get 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 16, we get 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 51

Advancing to step 4:
51 goes into 164 3 times with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 103.0
Subtract 153 from 164 to get 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 51

Step 5:
When dividing 114 by 51, we get 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 1032.0
If we subtract 102 from 114, we get 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 51

Advancing to step 6:
If we divide 123 by 51, we get 2 and a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 10322.0
Subtract 102 from 123 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
When dividing 210 by 51, we get 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 10322.4
If we take 204 away from 210, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
When dividing 60 by 51, we get 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 10322.41
If we take 51 away from 60, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
51 goes into 90 1 times with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 10322.411
If we take 51 away from 90, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

After the division, we end up with 10322.411 and a remainder of 0.0039.
