We look at the division of 88180405 by 395 
The aim is to understand the frequency of 395 in 88180405.

Advancing to step 1:
395 goes into 8 0 times with 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 / 395

On to step 2:
395 can be fit into 88 0 times, resulting in a remainder of 88.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 88, we get 88.
Bring next digit (1) of the dividend behind the 88 and repeat the process: 881 / 395

Step 3:
395 goes into 881 2 times with a remainder of 91.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 790 from 881 to get 91.
Fetch the next digit (8) from the dividend, attach it to 91 and continue: 918 / 395

Going ahead to step 4:
395 goes into 918 2 times with a remainder of 128.
The next digit of our result is 2. 
Result so far: 22.0
Subtract 790 from 918 to get 128.
Bring next digit (0) of the dividend behind the 128 and repeat the process: 1280 / 395

On to step 5:
When dividing 1280 by 395, we get 3 with a remainder of 95.
The number 3 becomes the next digit in our result. 
Result so far: 223.0
Deduct 1185 from 1280 and we're left with 95.
Take the next digit (4) from the dividend and append it to 95, then repeat: 954 / 395

Step 6:
The number 395 fits into 954 2 times, leaving a remainder of 164.
The next digit of our result is 2. 
Result so far: 2232.0
Deduct 790 from 954 and we're left with 164.
Take the next digit (0) from the dividend and append it to 164, then repeat: 1640 / 395

Let's proceed to step 7:
395 can be fit into 1640 4 times, resulting in a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 22324.0
If we subtract 1580 from 1640, we get 60.
Fetch the next digit (5) from the dividend, attach it to 60 and continue: 605 / 395

Advancing to step 8:
605 divided by 395 is 1 with a remainder of 210.
The next digit of our result is 1. 
Result so far: 223241.0
If we subtract 395 from 605, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 9:
The number 395 fits into 2100 5 times, leaving a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 223241.5
Deduct 1975 from 2100 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 10:
When dividing 1250 by 395, we get 3 with a remainder of 65.
The number 3 becomes the next digit in our result. 
Result so far: 223241.53
If we take 1185 away from 1250, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 11:
If we divide 650 by 395, we get 1 and a remainder of 255.
The number 1 becomes the next digit in our result. 
Result so far: 223241.531
Subtract 395 from 650 to get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Going ahead to step 12:
If we divide 2550 by 395, we get 6 and a remainder of 180.
Record the quotient 6 as the next digit in the result. 
Result so far: 223241.5316
If we subtract 2370 from 2550, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 13:
1800 divided by 395 is 4 with a remainder of 220.
Record the quotient 4 as the next digit in the result. 
Result so far: 223241.53164
Subtract 1580 from 1800 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 14:
395 goes into 2200 5 times with a remainder of 225.
The next digit of our result is 5. 
Result so far: 223241.531645
If we take 1975 away from 2200, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 15:
The number 395 fits into 2250 5 times, leaving a remainder of 275.
The next digit of our result is 5. 
Result so far: 223241.5316455
If we take 1975 away from 2250, we end up with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Our division results in 223241.5316455 with a remaining 2.75e-06.
