We divide 21874020 by 395
The aim is to understand the frequency of 395 in 21874020.

Advancing to step 1:
2 divided by 395 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 395

Step 2:
If we divide 21 by 395, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 395

Moving on to step 3:
395 goes into 218 0 times with a remainder of 218.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 218 to get 218.
Grab the next digit (7) from the dividend, add it to 218, then carry on: 2187 / 395

Advancing to step 4:
The number 395 fits into 2187 5 times, leaving a remainder of 212.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 1975 from 2187, we get 212.
Include the next digit (4) from the dividend after 212, then repeat: 2124 / 395

Step 5:
395 can be fit into 2124 5 times, resulting in a remainder of 149.
Record the quotient 5 as the next digit in the result. 
Result so far: 55.0
Deduct 1975 from 2124 and we're left with 149.
Bring next digit (0) of the dividend behind the 149 and repeat the process: 1490 / 395

Step 6:
395 goes into 1490 3 times with a remainder of 305.
Use 3 as the next digit of our solution. 
Result so far: 553.0
Deduct 1185 from 1490 and we're left with 305.
Include the next digit (2) from the dividend after 305, then repeat: 3052 / 395

Moving on to step 7:
395 goes into 3052 7 times with a remainder of 287.
Put 7 as the next digit of the answer. 
Result so far: 5537.0
If we subtract 2765 from 3052, we get 287.
Bring next digit (0) of the dividend behind the 287 and repeat the process: 2870 / 395

Step 8:
If we divide 2870 by 395, we get 7 and a remainder of 105.
The next digit of our result is 7. 
Result so far: 55377.0
Subtract 2765 from 2870 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 9:
If we divide 1050 by 395, we get 2 and a remainder of 260.
Write down 2 as next digit of the result. 
Result so far: 55377.2
Subtract 790 from 1050 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 10:
395 can be fit into 2600 6 times, resulting in a remainder of 230.
The number 6 becomes the next digit in our result. 
Result so far: 55377.26
If we take 2370 away from 2600, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 11:
If we divide 2300 by 395, we get 5 and a remainder of 325.
Record the quotient 5 as the next digit in the result. 
Result so far: 55377.265
Subtract 1975 from 2300 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Let's proceed to step 12:
If we divide 3250 by 395, we get 8 and a remainder of 90.
Record the quotient 8 as the next digit in the result. 
Result so far: 55377.2658
Deduct 3160 from 3250 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 13:
The number 395 fits into 900 2 times, leaving a remainder of 110.
Put 2 as the next digit of the answer. 
Result so far: 55377.26582
Subtract 790 from 900 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 14:
When dividing 1100 by 395, we get 2 with a remainder of 310.
The number 2 becomes the next digit in our result. 
Result so far: 55377.265822
If we subtract 790 from 1100, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

The quotient of the division is 55377.265822, and the remainder is 3.1e-05.
