We're dividing 97555568 by 869 
The aim is to understand the frequency of 869 in 97555568.

Moving on to step 1:
869 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 869

Going ahead to step 2:
When dividing 97 by 869, we get 0 with a remainder of 97.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 97, we get 97.
Fetch the next digit (5) from the dividend, attach it to 97 and continue: 975 / 869

On to step 3:
869 can be fit into 975 1 times, resulting in a remainder of 106.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 869 from 975 to get 106.
Append the next digit (5) from the dividend to 106 and continue with: 1065 / 869

Step 4:
When dividing 1065 by 869, we get 1 with a remainder of 196.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtracting 869 from 1065 leaves us with 196.
Grab the next digit (5) from the dividend, add it to 196, then carry on: 1965 / 869

On to step 5:
If we divide 1965 by 869, we get 2 and a remainder of 227.
Put 2 as the next digit of the answer. 
Result so far: 112.0
Subtract 1738 from 1965 to get 227.
Bring next digit (5) of the dividend behind the 227 and repeat the process: 2275 / 869

Let's proceed to step 6:
2275 divided by 869 is 2 with a remainder of 537.
The next digit of our result is 2. 
Result so far: 1122.0
If we take 1738 away from 2275, we end up with 537.
Take the next digit (6) from the dividend and append it to 537, then repeat: 5376 / 869

Going ahead to step 7:
869 can be fit into 5376 6 times, resulting in a remainder of 162.
Use 6 as the next digit of our solution. 
Result so far: 11226.0
Deduct 5214 from 5376 and we're left with 162.
Append the next digit (8) from the dividend to 162 and continue with: 1628 / 869

Moving on to step 8:
The number 869 fits into 1628 1 times, leaving a remainder of 759.
Write down 1 as next digit of the result. 
Result so far: 112261.0
Subtracting 869 from 1628 leaves us with 759.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7590, and continue the process.

Step 9:
When dividing 7590 by 869, we get 8 with a remainder of 638.
Put 8 as the next digit of the answer. 
Result so far: 112261.8
The remainder is 638 after subtracting 6952 from 7590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Going ahead to step 10:
6380 divided by 869 is 7 with a remainder of 297.
Use 7 as the next digit of our solution. 
Result so far: 112261.87
Deduct 6083 from 6380 and we're left with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Moving on to step 11:
2970 divided by 869 is 3 with a remainder of 363.
Put 3 as the next digit of the answer. 
Result so far: 112261.873
Deduct 2607 from 2970 and we're left with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Step 12:
3630 divided by 869 is 4 with a remainder of 154.
Record the quotient 4 as the next digit in the result. 
Result so far: 112261.8734
Subtracting 3476 from 3630 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 13:
1540 divided by 869 is 1 with a remainder of 671.
The next digit of our result is 1. 
Result so far: 112261.87341
Subtracting 869 from 1540 leaves us with 671.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6710, and continue the process.

Let's proceed to step 14:
The number 869 fits into 6710 7 times, leaving a remainder of 627.
Use 7 as the next digit of our solution. 
Result so far: 112261.873417
If we subtract 6083 from 6710, we get 627.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6270, and continue the process.

Going ahead to step 15:
If we divide 6270 by 869, we get 7 and a remainder of 187.
Use 7 as the next digit of our solution. 
Result so far: 112261.8734177
Subtract 6083 from 6270 to get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

The final result is 112261.8734177 with a remainder of 1.87e-06.
