Let's divide 84455452 by 870
The aim is to understand the frequency of 870 in 84455452.

Step 1:
The number 870 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 870

Moving on to step 2:
870 can be fit into 84 0 times, resulting in a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Take the next digit (4) from the dividend and append it to 84, then repeat: 844 / 870

Let's proceed to step 3:
844 divided by 870 is 0 with a remainder of 844.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 844, we get 844.
Bring next digit (5) of the dividend behind the 844 and repeat the process: 8445 / 870

Going ahead to step 4:
870 can be fit into 8445 9 times, resulting in a remainder of 615.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 7830 from 8445, we get 615.
Bring next digit (5) of the dividend behind the 615 and repeat the process: 6155 / 870

Moving on to step 5:
870 can be fit into 6155 7 times, resulting in a remainder of 65.
Use 7 as the next digit of our solution. 
Result so far: 97.0
The remainder is 65 after subtracting 6090 from 6155.
Take the next digit (4) from the dividend and append it to 65, then repeat: 654 / 870

Step 6:
The number 870 fits into 654 0 times, leaving a remainder of 654.
Write down 0 as next digit of the result. 
Result so far: 970.0
Subtract 0 from 654 to get 654.
Take the next digit (5) from the dividend and append it to 654, then repeat: 6545 / 870

Moving on to step 7:
When dividing 6545 by 870, we get 7 with a remainder of 455.
Put 7 as the next digit of the answer. 
Result so far: 9707.0
Subtract 6090 from 6545 to get 455.
Include the next digit (2) from the dividend after 455, then repeat: 4552 / 870

Advancing to step 8:
4552 divided by 870 is 5 with a remainder of 202.
The next digit of our result is 5. 
Result so far: 97075.0
If we subtract 4350 from 4552, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

On to step 9:
870 can be fit into 2020 2 times, resulting in a remainder of 280.
Write down 2 as next digit of the result. 
Result so far: 97075.2
If we take 1740 away from 2020, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 10:
2800 divided by 870 is 3 with a remainder of 190.
Record the quotient 3 as the next digit in the result. 
Result so far: 97075.23
If we take 2610 away from 2800, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 11:
When dividing 1900 by 870, we get 2 with a remainder of 160.
Put 2 as the next digit of the answer. 
Result so far: 97075.232
If we subtract 1740 from 1900, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 12:
870 goes into 1600 1 times with a remainder of 730.
The number 1 becomes the next digit in our result. 
Result so far: 97075.2321
Deduct 870 from 1600 and we're left with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Moving on to step 13:
870 can be fit into 7300 8 times, resulting in a remainder of 340.
Use 8 as the next digit of our solution. 
Result so far: 97075.23218
Deduct 6960 from 7300 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 14:
870 goes into 3400 3 times with a remainder of 790.
The next digit of our result is 3. 
Result so far: 97075.232183
Deduct 2610 from 3400 and we're left with 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

On to step 15:
870 can be fit into 7900 9 times, resulting in a remainder of 70.
Put 9 as the next digit of the answer. 
Result so far: 97075.2321839
Subtract 7830 from 7900 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 16:
700 divided by 870 is 0 with a remainder of 700.
Write down 0 as next digit of the result. 
Result so far: 97075.2321839
The remainder is 700 after subtracting 0 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

The final result is 97075.2321839 with a remainder of 7e-07.
