We're dividing 88465869 by 39 
The aim is to understand the frequency of 39 in 88465869.

Step 1:
The number 39 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 39

Let's proceed to step 2:
88 divided by 39 is 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 78 away from 88, we end up with 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 39

Moving on to step 3:
When dividing 104 by 39, we get 2 with a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we take 78 away from 104, we end up with 26.
Append the next digit (6) from the dividend to 26 and continue with: 266 / 39

On to step 4:
When dividing 266 by 39, we get 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 226.0
Subtracting 234 from 266 leaves us with 32.
Fetch the next digit (5) from the dividend, attach it to 32 and continue: 325 / 39

On to step 5:
The number 39 fits into 325 8 times, leaving a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 2268.0
Subtracting 312 from 325 leaves us with 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 39

Moving on to step 6:
138 divided by 39 is 3 with a remainder of 21.
The next digit of our result is 3. 
Result so far: 22683.0
Subtract 117 from 138 to get 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 39

Going ahead to step 7:
39 can be fit into 216 5 times, resulting in a remainder of 21.
Use 5 as the next digit of our solution. 
Result so far: 226835.0
Subtract 195 from 216 to get 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 39

Moving on to step 8:
If we divide 219 by 39, we get 5 and a remainder of 24.
The next digit of our result is 5. 
Result so far: 2268355.0
Deduct 195 from 219 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
The number 39 fits into 240 6 times, leaving a remainder of 6.
The next digit of our result is 6. 
Result so far: 2268355.6
Deduct 234 from 240 and we're left 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.

On to step 10:
If we divide 60 by 39, we get 1 and a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 2268355.61
Subtract 39 from 60 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.

Moving on to step 11:
If we divide 210 by 39, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 2268355.615
Deduct 195 from 210 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 12:
The number 39 fits into 150 3 times, leaving a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 2268355.6153
Deduct 117 from 150 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 13:
39 goes into 330 8 times with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 2268355.61538
Subtract 312 from 330 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 14:
The number 39 fits into 180 4 times, leaving a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 2268355.615384
If we subtract 156 from 180, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 15:
The number 39 fits into 240 6 times, leaving a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 2268355.6153846
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 16:
The number 39 fits into 60 1 times, leaving a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 2268355.61538461
Subtracting 39 from 60 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

In conclusion, the division gives 2268355.61538461 with a balance of 2.1e-08.
