Let's divide 89722721 by 395
The aim is to understand the frequency of 395 in 89722721.

On to step 1:
395 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 395

Let's proceed to step 2:
89 divided by 395 is 0 with a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 89 after subtracting 0 from 89.
Fetch the next digit (7) from the dividend, attach it to 89 and continue: 897 / 395

On to step 3:
395 can be fit into 897 2 times, resulting in a remainder of 107.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 790 from 897 to get 107.
Bring next digit (2) of the dividend behind the 107 and repeat the process: 1072 / 395

On to step 4:
395 goes into 1072 2 times with a remainder of 282.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
If we subtract 790 from 1072, we get 282.
Take the next digit (2) from the dividend and append it to 282, then repeat: 2822 / 395

Moving on to step 5:
If we divide 2822 by 395, we get 7 and a remainder of 57.
The number 7 becomes the next digit in our result. 
Result so far: 227.0
Subtracting 2765 from 2822 leaves us with 57.
Take the next digit (7) from the dividend and append it to 57, then repeat: 577 / 395

On to step 6:
395 can be fit into 577 1 times, resulting in a remainder of 182.
Put 1 as the next digit of the answer. 
Result so far: 2271.0
The remainder is 182 after subtracting 395 from 577.
Take the next digit (2) from the dividend and append it to 182, then repeat: 1822 / 395

On to step 7:
When dividing 1822 by 395, we get 4 with a remainder of 242.
Put 4 as the next digit of the answer. 
Result so far: 22714.0
Deduct 1580 from 1822 and we're left with 242.
Take the next digit (1) from the dividend and append it to 242, then repeat: 2421 / 395

Let's proceed to step 8:
When dividing 2421 by 395, we get 6 with a remainder of 51.
Write down 6 as next digit of the result. 
Result so far: 227146.0
Subtract 2370 from 2421 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 9:
When dividing 510 by 395, we get 1 with a remainder of 115.
Put 1 as the next digit of the answer. 
Result so far: 227146.1
The remainder is 115 after subtracting 395 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 10:
When dividing 1150 by 395, we get 2 with a remainder of 360.
Put 2 as the next digit of the answer. 
Result so far: 227146.12
The remainder is 360 after subtracting 790 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 11:
395 can be fit into 3600 9 times, resulting in a remainder of 45.
Record the quotient 9 as the next digit in the result. 
Result so far: 227146.129
If we subtract 3555 from 3600, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 12:
The number 395 fits into 450 1 times, leaving a remainder of 55.
The number 1 becomes the next digit in our result. 
Result so far: 227146.1291
Subtracting 395 from 450 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 13:
550 divided by 395 is 1 with a remainder of 155.
Put 1 as the next digit of the answer. 
Result so far: 227146.12911
If we take 395 away from 550, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

After the division, we end up with 227146.12911 and a remainder of 0.000155.
