We're dividing 35129037 by 579 
The aim is to understand the frequency of 579 in 35129037.

Step 1:
When dividing 3 by 579, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 579

Step 2:
579 can be fit into 35 0 times, resulting in a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Fetch the next digit (1) from the dividend, attach it to 35 and continue: 351 / 579

Advancing to step 3:
351 divided by 579 is 0 with a remainder of 351.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 351 to get 351.
Take the next digit (2) from the dividend and append it to 351, then repeat: 3512 / 579

Advancing to step 4:
When dividing 3512 by 579, we get 6 with a remainder of 38.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 3474 from 3512, we get 38.
Grab the next digit (9) from the dividend, add it to 38, then carry on: 389 / 579

Moving on to step 5:
389 divided by 579 is 0 with a remainder of 389.
Record the quotient 0 as the next digit in the result. 
Result so far: 60.0
If we subtract 0 from 389, we get 389.
Append the next digit (0) from the dividend to 389 and continue with: 3890 / 579

Step 6:
The number 579 fits into 3890 6 times, leaving a remainder of 416.
The number 6 becomes the next digit in our result. 
Result so far: 606.0
If we take 3474 away from 3890, we end up with 416.
Append the next digit (3) from the dividend to 416 and continue with: 4163 / 579

Advancing to step 7:
579 can be fit into 4163 7 times, resulting in a remainder of 110.
Use 7 as the next digit of our solution. 
Result so far: 6067.0
If we take 4053 away from 4163, we end up with 110.
Take the next digit (7) from the dividend and append it to 110, then repeat: 1107 / 579

Let's proceed to step 8:
579 goes into 1107 1 times with a remainder of 528.
Record the quotient 1 as the next digit in the result. 
Result so far: 60671.0
If we take 579 away from 1107, we end up with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Let's proceed to step 9:
5280 divided by 579 is 9 with a remainder of 69.
The number 9 becomes the next digit in our result. 
Result so far: 60671.9
If we take 5211 away from 5280, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 10:
The number 579 fits into 690 1 times, leaving a remainder of 111.
Write down 1 as next digit of the result. 
Result so far: 60671.91
Subtract 579 from 690 to get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Advancing to step 11:
579 goes into 1110 1 times with a remainder of 531.
Use 1 as the next digit of our solution. 
Result so far: 60671.911
Deduct 579 from 1110 and we're left with 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

The final result is 60671.911 with a remainder of 0.0531.
