Let's divide 10312663 by 869
The aim is to understand the frequency of 869 in 10312663.

Step 1:
The number 869 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 869

Moving on to step 2:
869 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 869

Moving on to step 3:
869 can be fit into 103 0 times, resulting in a remainder of 103.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 103, we end up with 103.
Grab the next digit (1) from the dividend, add it to 103, then carry on: 1031 / 869

Going ahead to step 4:
The number 869 fits into 1031 1 times, leaving a remainder of 162.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 869 from 1031 and we're left with 162.
Bring next digit (2) of the dividend behind the 162 and repeat the process: 1622 / 869

Step 5:
If we divide 1622 by 869, we get 1 and a remainder of 753.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 753 after subtracting 869 from 1622.
Grab the next digit (6) from the dividend, add it to 753, then carry on: 7536 / 869

Let's proceed to step 6:
7536 divided by 869 is 8 with a remainder of 584.
The next digit of our result is 8. 
Result so far: 118.0
If we subtract 6952 from 7536, we get 584.
Append the next digit (6) from the dividend to 584 and continue with: 5846 / 869

Step 7:
If we divide 5846 by 869, we get 6 and a remainder of 632.
Use 6 as the next digit of our solution. 
Result so far: 1186.0
The remainder is 632 after subtracting 5214 from 5846.
Fetch the next digit (3) from the dividend, attach it to 632 and continue: 6323 / 869

Let's proceed to step 8:
The number 869 fits into 6323 7 times, leaving a remainder of 240.
Put 7 as the next digit of the answer. 
Result so far: 11867.0
If we take 6083 away from 6323, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 9:
2400 divided by 869 is 2 with a remainder of 662.
The number 2 becomes the next digit in our result. 
Result so far: 11867.2
The remainder is 662 after subtracting 1738 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

On to step 10:
If we divide 6620 by 869, we get 7 and a remainder of 537.
Record the quotient 7 as the next digit in the result. 
Result so far: 11867.27
Deduct 6083 from 6620 and we're left with 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

Advancing to step 11:
The number 869 fits into 5370 6 times, leaving a remainder of 156.
The number 6 becomes the next digit in our result. 
Result so far: 11867.276
If we take 5214 away from 5370, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 12:
The number 869 fits into 1560 1 times, leaving a remainder of 691.
Use 1 as the next digit of our solution. 
Result so far: 11867.2761
Subtract 869 from 1560 to get 691.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6910, and continue the process.

Moving on to step 13:
869 can be fit into 6910 7 times, resulting in a remainder of 827.
Record the quotient 7 as the next digit in the result. 
Result so far: 11867.27617
If we subtract 6083 from 6910, we get 827.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8270, and continue the process.

Advancing to step 14:
The number 869 fits into 8270 9 times, leaving a remainder of 449.
Record the quotient 9 as the next digit in the result. 
Result so far: 11867.276179
Subtracting 7821 from 8270 leaves us with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Advancing to step 15:
4490 divided by 869 is 5 with a remainder of 145.
Write down 5 as next digit of the result. 
Result so far: 11867.2761795
If we subtract 4345 from 4490, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 16:
1450 divided by 869 is 1 with a remainder of 581.
Use 1 as the next digit of our solution. 
Result so far: 11867.27617951
Subtract 869 from 1450 to get 581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

The final result is 11867.27617951 with a remainder of 5.81e-07.
