We look at the division of 73893074 by 865 
The aim is to understand the frequency of 865 in 73893074.

Advancing to step 1:
7 divided by 865 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 865

Going ahead to step 2:
73 divided by 865 is 0 with a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Grab the next digit (8) from the dividend, add it to 73, then carry on: 738 / 865

Moving on to step 3:
865 goes into 738 0 times with a remainder of 738.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 738 to get 738.
Take the next digit (9) from the dividend and append it to 738, then repeat: 7389 / 865

On to step 4:
When dividing 7389 by 865, we get 8 with a remainder of 469.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 6920 away from 7389, we end up with 469.
Take the next digit (3) from the dividend and append it to 469, then repeat: 4693 / 865

Going ahead to step 5:
4693 divided by 865 is 5 with a remainder of 368.
Use 5 as the next digit of our solution. 
Result so far: 85.0
Subtracting 4325 from 4693 leaves us with 368.
Take the next digit (0) from the dividend and append it to 368, then repeat: 3680 / 865

Advancing to step 6:
When dividing 3680 by 865, we get 4 with a remainder of 220.
Put 4 as the next digit of the answer. 
Result so far: 854.0
If we take 3460 away from 3680, we end up with 220.
Grab the next digit (7) from the dividend, add it to 220, then carry on: 2207 / 865

On to step 7:
If we divide 2207 by 865, we get 2 and a remainder of 477.
Write down 2 as next digit of the result. 
Result so far: 8542.0
Subtracting 1730 from 2207 leaves us with 477.
Fetch the next digit (4) from the dividend, attach it to 477 and continue: 4774 / 865

Going ahead to step 8:
4774 divided by 865 is 5 with a remainder of 449.
Put 5 as the next digit of the answer. 
Result so far: 85425.0
Subtract 4325 from 4774 to get 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Moving on to step 9:
If we divide 4490 by 865, we get 5 and a remainder of 165.
Record the quotient 5 as the next digit in the result. 
Result so far: 85425.5
Subtracting 4325 from 4490 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 10:
865 can be fit into 1650 1 times, resulting in a remainder of 785.
Put 1 as the next digit of the answer. 
Result so far: 85425.51
If we take 865 away from 1650, we end up with 785.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7850, and continue the process.

Moving on to step 11:
The number 865 fits into 7850 9 times, leaving a remainder of 65.
Record the quotient 9 as the next digit in the result. 
Result so far: 85425.519
Subtracting 7785 from 7850 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 12:
865 can be fit into 650 0 times, resulting in a remainder of 650.
Record the quotient 0 as the next digit in the result. 
Result so far: 85425.519
If we take 0 away from 650, we end up with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Step 13:
When dividing 6500 by 865, we get 7 with a remainder of 445.
The number 7 becomes the next digit in our result. 
Result so far: 85425.51907
The remainder is 445 after subtracting 6055 from 6500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Moving on to step 14:
865 can be fit into 4450 5 times, resulting in a remainder of 125.
The next digit of our result is 5. 
Result so far: 85425.519075
Subtract 4325 from 4450 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 15:
865 goes into 1250 1 times with a remainder of 385.
Use 1 as the next digit of our solution. 
Result so far: 85425.5190751
Subtract 865 from 1250 to get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Moving on to step 16:
The number 865 fits into 3850 4 times, leaving a remainder of 390.
Write down 4 as next digit of the result. 
Result so far: 85425.51907514
If we take 3460 away from 3850, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

The quotient of the division is 85425.51907514, and the remainder is 3.9e-07.
