We're dividing 86311348 by 873 
The aim is to understand the frequency of 873 in 86311348.

Let's proceed to step 1:
8 divided by 873 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 873

On to step 2:
86 divided by 873 is 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Include the next digit (3) from the dividend after 86, then repeat: 863 / 873

Going ahead to step 3:
863 divided by 873 is 0 with a remainder of 863.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 863 to get 863.
Include the next digit (1) from the dividend after 863, then repeat: 8631 / 873

Let's proceed to step 4:
When dividing 8631 by 873, we get 9 with a remainder of 774.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 7857 from 8631 leaves us with 774.
Fetch the next digit (1) from the dividend, attach it to 774 and continue: 7741 / 873

Let's proceed to step 5:
If we divide 7741 by 873, we get 8 and a remainder of 757.
The next digit of our result is 8. 
Result so far: 98.0
If we take 6984 away from 7741, we end up with 757.
Take the next digit (3) from the dividend and append it to 757, then repeat: 7573 / 873

Let's proceed to step 6:
If we divide 7573 by 873, we get 8 and a remainder of 589.
Put 8 as the next digit of the answer. 
Result so far: 988.0
Deduct 6984 from 7573 and we're left with 589.
Take the next digit (4) from the dividend and append it to 589, then repeat: 5894 / 873

Moving on to step 7:
5894 divided by 873 is 6 with a remainder of 656.
Put 6 as the next digit of the answer. 
Result so far: 9886.0
Subtract 5238 from 5894 to get 656.
Grab the next digit (8) from the dividend, add it to 656, then carry on: 6568 / 873

Moving on to step 8:
6568 divided by 873 is 7 with a remainder of 457.
The next digit of our result is 7. 
Result so far: 98867.0
The remainder is 457 after subtracting 6111 from 6568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Advancing to step 9:
When dividing 4570 by 873, we get 5 with a remainder of 205.
The number 5 becomes the next digit in our result. 
Result so far: 98867.5
Deduct 4365 from 4570 and we're left with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Moving on to step 10:
The number 873 fits into 2050 2 times, leaving a remainder of 304.
The number 2 becomes the next digit in our result. 
Result so far: 98867.52
If we subtract 1746 from 2050, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Moving on to step 11:
873 goes into 3040 3 times with a remainder of 421.
Record the quotient 3 as the next digit in the result. 
Result so far: 98867.523
The remainder is 421 after subtracting 2619 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Going ahead to step 12:
4210 divided by 873 is 4 with a remainder of 718.
Write down 4 as next digit of the result. 
Result so far: 98867.5234
If we take 3492 away from 4210, we end up with 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

Advancing to step 13:
The number 873 fits into 7180 8 times, leaving a remainder of 196.
The next digit of our result is 8. 
Result so far: 98867.52348
If we take 6984 away from 7180, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 14:
If we divide 1960 by 873, we get 2 and a remainder of 214.
Write down 2 as next digit of the result. 
Result so far: 98867.523482
If we subtract 1746 from 1960, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

On to step 15:
873 goes into 2140 2 times with a remainder of 394.
Put 2 as the next digit of the answer. 
Result so far: 98867.5234822
If we subtract 1746 from 2140, we get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

The final outcome is 98867.5234822, with a leftover of 3.94e-06.
