98163648 ÷ 873 
The aim is to understand the frequency of 873 in 98163648.

On to step 1:
873 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 873

Moving on to step 2:
873 goes into 98 0 times with a remainder of 98.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 98, we end up with 98.
Include the next digit (1) from the dividend after 98, then repeat: 981 / 873

Going ahead to step 3:
981 divided by 873 is 1 with a remainder of 108.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 873 from 981 leaves us with 108.
Take the next digit (6) from the dividend and append it to 108, then repeat: 1086 / 873

Let's proceed to step 4:
873 can be fit into 1086 1 times, resulting in a remainder of 213.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 873 from 1086 leaves us with 213.
Fetch the next digit (3) from the dividend, attach it to 213 and continue: 2133 / 873

On to step 5:
2133 divided by 873 is 2 with a remainder of 387.
Put 2 as the next digit of the answer. 
Result so far: 112.0
Subtract 1746 from 2133 to get 387.
Take the next digit (6) from the dividend and append it to 387, then repeat: 3876 / 873

Advancing to step 6:
873 can be fit into 3876 4 times, resulting in a remainder of 384.
Use 4 as the next digit of our solution. 
Result so far: 1124.0
If we take 3492 away from 3876, we end up with 384.
Grab the next digit (4) from the dividend, add it to 384, then carry on: 3844 / 873

Moving on to step 7:
873 goes into 3844 4 times with a remainder of 352.
The number 4 becomes the next digit in our result. 
Result so far: 11244.0
If we subtract 3492 from 3844, we get 352.
Take the next digit (8) from the dividend and append it to 352, then repeat: 3528 / 873

Advancing to step 8:
The number 873 fits into 3528 4 times, leaving a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 112444.0
If we take 3492 away from 3528, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
If we divide 360 by 873, we get 0 and a remainder of 360.
The next digit of our result is 0. 
Result so far: 112444.0
If we take 0 away from 360, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 10:
873 can be fit into 3600 4 times, resulting in a remainder of 108.
Write down 4 as next digit of the result. 
Result so far: 112444.04
Deduct 3492 from 3600 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 11:
When dividing 1080 by 873, we get 1 with a remainder of 207.
Write down 1 as next digit of the result. 
Result so far: 112444.041
Subtracting 873 from 1080 leaves us with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Going ahead to step 12:
The number 873 fits into 2070 2 times, leaving a remainder of 324.
Use 2 as the next digit of our solution. 
Result so far: 112444.0412
Deduct 1746 from 2070 and we're left with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Step 13:
When dividing 3240 by 873, we get 3 with a remainder of 621.
The next digit of our result is 3. 
Result so far: 112444.04123
Subtracting 2619 from 3240 leaves us with 621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6210, and continue the process.

Step 14:
The number 873 fits into 6210 7 times, leaving a remainder of 99.
The number 7 becomes the next digit in our result. 
Result so far: 112444.041237
If we subtract 6111 from 6210, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 15:
873 can be fit into 990 1 times, resulting in a remainder of 117.
Record the quotient 1 as the next digit in the result. 
Result so far: 112444.0412371
Subtract 873 from 990 to get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Advancing to step 16:
The number 873 fits into 1170 1 times, leaving a remainder of 297.
Put 1 as the next digit of the answer. 
Result so far: 112444.04123711
Subtract 873 from 1170 to get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

The final result is 112444.04123711 with a remainder of 2.97e-07.
