Let's divide 97645822 by 870
The aim is to understand the frequency of 870 in 97645822.

Let's proceed to step 1:
If we divide 9 by 870, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 870

Let's proceed to step 2:
870 goes into 97 0 times with a remainder of 97.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 97 leaves us with 97.
Grab the next digit (6) from the dividend, add it to 97, then carry on: 976 / 870

Step 3:
The number 870 fits into 976 1 times, leaving a remainder of 106.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 870 from 976 to get 106.
Append the next digit (4) from the dividend to 106 and continue with: 1064 / 870

Advancing to step 4:
1064 divided by 870 is 1 with a remainder of 194.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 870 from 1064, we get 194.
Fetch the next digit (5) from the dividend, attach it to 194 and continue: 1945 / 870

Let's proceed to step 5:
When dividing 1945 by 870, we get 2 with a remainder of 205.
Write down 2 as next digit of the result. 
Result so far: 112.0
Subtracting 1740 from 1945 leaves us with 205.
Include the next digit (8) from the dividend after 205, then repeat: 2058 / 870

On to step 6:
The number 870 fits into 2058 2 times, leaving a remainder of 318.
The number 2 becomes the next digit in our result. 
Result so far: 1122.0
Deduct 1740 from 2058 and we're left with 318.
Append the next digit (2) from the dividend to 318 and continue with: 3182 / 870

Let's proceed to step 7:
If we divide 3182 by 870, we get 3 and a remainder of 572.
Write down 3 as next digit of the result. 
Result so far: 11223.0
If we subtract 2610 from 3182, we get 572.
Grab the next digit (2) from the dividend, add it to 572, then carry on: 5722 / 870

Going ahead to step 8:
870 can be fit into 5722 6 times, resulting in a remainder of 502.
Use 6 as the next digit of our solution. 
Result so far: 112236.0
If we subtract 5220 from 5722, we get 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Step 9:
870 can be fit into 5020 5 times, resulting in a remainder of 670.
The number 5 becomes the next digit in our result. 
Result so far: 112236.5
If we subtract 4350 from 5020, we get 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Let's proceed to step 10:
870 can be fit into 6700 7 times, resulting in a remainder of 610.
The next digit of our result is 7. 
Result so far: 112236.57
Subtracting 6090 from 6700 leaves us with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

On to step 11:
870 goes into 6100 7 times with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 112236.577
The remainder is 10 after subtracting 6090 from 6100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 112236.577 with a remaining 0.001.
