Let's divide 64006138 by 579
The aim is to understand the frequency of 579 in 64006138.

On to step 1:
If we divide 6 by 579, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 579

On to step 2:
579 goes into 64 0 times with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Fetch the next digit (0) from the dividend, attach it to 64 and continue: 640 / 579

Step 3:
When dividing 640 by 579, we get 1 with a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 579 from 640, we get 61.
Append the next digit (0) from the dividend to 61 and continue with: 610 / 579

Going ahead to step 4:
The number 579 fits into 610 1 times, leaving a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 579 from 610 leaves us with 31.
Take the next digit (6) from the dividend and append it to 31, then repeat: 316 / 579

Moving on to step 5:
579 goes into 316 0 times with a remainder of 316.
Record the quotient 0 as the next digit in the result. 
Result so far: 110.0
Subtracting 0 from 316 leaves us with 316.
Grab the next digit (1) from the dividend, add it to 316, then carry on: 3161 / 579

Going ahead to step 6:
3161 divided by 579 is 5 with a remainder of 266.
Put 5 as the next digit of the answer. 
Result so far: 1105.0
Subtract 2895 from 3161 to get 266.
Include the next digit (3) from the dividend after 266, then repeat: 2663 / 579

Step 7:
2663 divided by 579 is 4 with a remainder of 347.
Write down 4 as next digit of the result. 
Result so far: 11054.0
Subtract 2316 from 2663 to get 347.
Include the next digit (8) from the dividend after 347, then repeat: 3478 / 579

Going ahead to step 8:
579 can be fit into 3478 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 110546.0
Subtract 3474 from 3478 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.

Advancing to step 9:
The number 579 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 110546.0
The remainder is 40 after subtracting 0 from 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:
When dividing 400 by 579, we get 0 with a remainder of 400.
The next digit of our result is 0. 
Result so far: 110546.0
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final result is 110546.0 with a remainder of 0.4.
