We divide 78165245 by 869
The aim is to understand the frequency of 869 in 78165245.

Step 1:
When dividing 7 by 869, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 869

Let's proceed to step 2:
If we divide 78 by 869, we get 0 and a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Grab the next digit (1) from the dividend, add it to 78, then carry on: 781 / 869

Step 3:
781 divided by 869 is 0 with a remainder of 781.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 781 and we're left with 781.
Grab the next digit (6) from the dividend, add it to 781, then carry on: 7816 / 869

Moving on to step 4:
When dividing 7816 by 869, we get 8 with a remainder of 864.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 6952 from 7816 leaves us with 864.
Include the next digit (5) from the dividend after 864, then repeat: 8645 / 869

On to step 5:
If we divide 8645 by 869, we get 9 and a remainder of 824.
Write down 9 as next digit of the result. 
Result so far: 89.0
Subtracting 7821 from 8645 leaves us with 824.
Take the next digit (2) from the dividend and append it to 824, then repeat: 8242 / 869

On to step 6:
8242 divided by 869 is 9 with a remainder of 421.
Use 9 as the next digit of our solution. 
Result so far: 899.0
Deduct 7821 from 8242 and we're left with 421.
Include the next digit (4) from the dividend after 421, then repeat: 4214 / 869

Step 7:
When dividing 4214 by 869, we get 4 with a remainder of 738.
Put 4 as the next digit of the answer. 
Result so far: 8994.0
The remainder is 738 after subtracting 3476 from 4214.
Include the next digit (5) from the dividend after 738, then repeat: 7385 / 869

Moving on to step 8:
The number 869 fits into 7385 8 times, leaving a remainder of 433.
The next digit of our result is 8. 
Result so far: 89948.0
Deduct 6952 from 7385 and we're left with 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Let's proceed to step 9:
When dividing 4330 by 869, we get 4 with a remainder of 854.
Put 4 as the next digit of the answer. 
Result so far: 89948.4
If we take 3476 away from 4330, we end up with 854.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8540, and continue the process.

Moving on to step 10:
869 can be fit into 8540 9 times, resulting in a remainder of 719.
The next digit of our result is 9. 
Result so far: 89948.49
Subtracting 7821 from 8540 leaves us with 719.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7190, and continue the process.

Moving on to step 11:
If we divide 7190 by 869, we get 8 and a remainder of 238.
Record the quotient 8 as the next digit in the result. 
Result so far: 89948.498
Subtracting 6952 from 7190 leaves us with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 12:
869 can be fit into 2380 2 times, resulting in a remainder of 642.
The next digit of our result is 2. 
Result so far: 89948.4982
If we take 1738 away from 2380, we end up with 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

Let's proceed to step 13:
If we divide 6420 by 869, we get 7 and a remainder of 337.
Put 7 as the next digit of the answer. 
Result so far: 89948.49827
The remainder is 337 after subtracting 6083 from 6420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Moving on to step 14:
If we divide 3370 by 869, we get 3 and a remainder of 763.
Write down 3 as next digit of the result. 
Result so far: 89948.498273
The remainder is 763 after subtracting 2607 from 3370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7630, and continue the process.

On to step 15:
869 goes into 7630 8 times with a remainder of 678.
The next digit of our result is 8. 
Result so far: 89948.4982738
The remainder is 678 after subtracting 6952 from 7630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

Going ahead to step 16:
869 goes into 6780 7 times with a remainder of 697.
Put 7 as the next digit of the answer. 
Result so far: 89948.49827387
Subtract 6083 from 6780 to get 697.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6970, and continue the process.

The quotient of the division is 89948.49827387, and the remainder is 6.97e-07.
