We're dividing 35389613 by 538 
The aim is to understand the frequency of 538 in 35389613.

On to step 1:
538 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 538

Advancing to step 2:
538 goes into 35 0 times with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Grab the next digit (3) from the dividend, add it to 35, then carry on: 353 / 538

Step 3:
If we divide 353 by 538, we get 0 and a remainder of 353.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 353 after subtracting 0 from 353.
Include the next digit (8) from the dividend after 353, then repeat: 3538 / 538

Advancing to step 4:
The number 538 fits into 3538 6 times, leaving a remainder of 310.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 3228 from 3538 to get 310.
Append the next digit (9) from the dividend to 310 and continue with: 3109 / 538

Let's proceed to step 5:
When dividing 3109 by 538, we get 5 with a remainder of 419.
Write down 5 as next digit of the result. 
Result so far: 65.0
Subtracting 2690 from 3109 leaves us with 419.
Bring next digit (6) of the dividend behind the 419 and repeat the process: 4196 / 538

Moving on to step 6:
The number 538 fits into 4196 7 times, leaving a remainder of 430.
Use 7 as the next digit of our solution. 
Result so far: 657.0
If we take 3766 away from 4196, we end up with 430.
Take the next digit (1) from the dividend and append it to 430, then repeat: 4301 / 538

Advancing to step 7:
If we divide 4301 by 538, we get 7 and a remainder of 535.
The number 7 becomes the next digit in our result. 
Result so far: 6577.0
Subtracting 3766 from 4301 leaves us with 535.
Take the next digit (3) from the dividend and append it to 535, then repeat: 5353 / 538

Going ahead to step 8:
If we divide 5353 by 538, we get 9 and a remainder of 511.
The next digit of our result is 9. 
Result so far: 65779.0
Subtract 4842 from 5353 to get 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Advancing to step 9:
The number 538 fits into 5110 9 times, leaving a remainder of 268.
The next digit of our result is 9. 
Result so far: 65779.9
If we take 4842 away from 5110, we end up with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Moving on to step 10:
538 goes into 2680 4 times with a remainder of 528.
Write down 4 as next digit of the result. 
Result so far: 65779.94
Subtract 2152 from 2680 to get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Moving on to step 11:
When dividing 5280 by 538, we get 9 with a remainder of 438.
The number 9 becomes the next digit in our result. 
Result so far: 65779.949
Subtracting 4842 from 5280 leaves us with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Moving on to step 12:
The number 538 fits into 4380 8 times, leaving a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 65779.9498
Subtract 4304 from 4380 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 13:
538 can be fit into 760 1 times, resulting in a remainder of 222.
The next digit of our result is 1. 
Result so far: 65779.94981
Deduct 538 from 760 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Let's proceed to step 14:
When dividing 2220 by 538, we get 4 with a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 65779.949814
Subtracting 2152 from 2220 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 15:
538 goes into 680 1 times with a remainder of 142.
Record the quotient 1 as the next digit in the result. 
Result so far: 65779.9498141
Subtracting 538 from 680 leaves us with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Let's proceed to step 16:
538 can be fit into 1420 2 times, resulting in a remainder of 344.
Record the quotient 2 as the next digit in the result. 
Result so far: 65779.94981412
The remainder is 344 after subtracting 1076 from 1420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

In conclusion, the division gives 65779.94981412 with a balance of 3.44e-07.
