99980256 divided by 395 
The aim is to understand the frequency of 395 in 99980256.

Going ahead to step 1:
The number 395 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 395

Let's proceed to step 2:
395 goes into 99 0 times with a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Fetch the next digit (9) from the dividend, attach it to 99 and continue: 999 / 395

Advancing to step 3:
If we divide 999 by 395, we get 2 and a remainder of 209.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 209 after subtracting 790 from 999.
Take the next digit (8) from the dividend and append it to 209, then repeat: 2098 / 395

Going ahead to step 4:
395 goes into 2098 5 times with a remainder of 123.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Deduct 1975 from 2098 and we're left with 123.
Bring next digit (0) of the dividend behind the 123 and repeat the process: 1230 / 395

Moving on to step 5:
1230 divided by 395 is 3 with a remainder of 45.
Put 3 as the next digit of the answer. 
Result so far: 253.0
If we subtract 1185 from 1230, we get 45.
Take the next digit (2) from the dividend and append it to 45, then repeat: 452 / 395

Let's proceed to step 6:
When dividing 452 by 395, we get 1 with a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 2531.0
Subtract 395 from 452 to get 57.
Append the next digit (5) from the dividend to 57 and continue with: 575 / 395

Advancing to step 7:
When dividing 575 by 395, we get 1 with a remainder of 180.
The number 1 becomes the next digit in our result. 
Result so far: 25311.0
If we take 395 away from 575, we end up with 180.
Grab the next digit (6) from the dividend, add it to 180, then carry on: 1806 / 395

Advancing to step 8:
When dividing 1806 by 395, we get 4 with a remainder of 226.
Record the quotient 4 as the next digit in the result. 
Result so far: 253114.0
Subtracting 1580 from 1806 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Moving on to step 9:
When dividing 2260 by 395, we get 5 with a remainder of 285.
Use 5 as the next digit of our solution. 
Result so far: 253114.5
If we subtract 1975 from 2260, we get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Going ahead to step 10:
The number 395 fits into 2850 7 times, leaving a remainder of 85.
The next digit of our result is 7. 
Result so far: 253114.57
Subtract 2765 from 2850 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 11:
The number 395 fits into 850 2 times, leaving a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 253114.572
Deduct 790 from 850 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 12:
395 goes into 600 1 times with a remainder of 205.
Write down 1 as next digit of the result. 
Result so far: 253114.5721
Deduct 395 from 600 and we're left with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Let's proceed to step 13:
395 can be fit into 2050 5 times, resulting in a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 253114.57215
Subtracting 1975 from 2050 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 14:
395 can be fit into 750 1 times, resulting in a remainder of 355.
The number 1 becomes the next digit in our result. 
Result so far: 253114.572151
Deduct 395 from 750 and we're left with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Going ahead to step 15:
The number 395 fits into 3550 8 times, leaving a remainder of 390.
Use 8 as the next digit of our solution. 
Result so far: 253114.5721518
The remainder is 390 after subtracting 3160 from 3550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 16:
3900 divided by 395 is 9 with a remainder of 345.
Use 9 as the next digit of our solution. 
Result so far: 253114.57215189
The remainder is 345 after subtracting 3555 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

After the division, we end up with 253114.57215189 and a remainder of 3.45e-07.
