781015 ÷ 98 
The aim is to understand the frequency of 98 in 781015.

Moving on to step 1:
When dividing 7 by 98, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 98

Advancing to step 2:
98 can be fit into 78 0 times, resulting in a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Fetch the next digit (1) from the dividend, attach it to 78 and continue: 781 / 98

On to step 3:
The number 98 fits into 781 7 times, leaving a remainder of 95.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 686 from 781 to get 95.
Bring next digit (0) of the dividend behind the 95 and repeat the process: 950 / 98

Moving on to step 4:
98 goes into 950 9 times with a remainder of 68.
Use 9 as the next digit of our solution. 
Result so far: 79.0
Subtracting 882 from 950 leaves us with 68.
Append the next digit (1) from the dividend to 68 and continue with: 681 / 98

Moving on to step 5:
98 goes into 681 6 times with a remainder of 93.
Use 6 as the next digit of our solution. 
Result so far: 796.0
If we take 588 away from 681, we end up with 93.
Include the next digit (5) from the dividend after 93, then repeat: 935 / 98

Let's proceed to step 6:
If we divide 935 by 98, we get 9 and a remainder of 53.
The number 9 becomes the next digit in our result. 
Result so far: 7969.0
The remainder is 53 after subtracting 882 from 935.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 7:
98 can be fit into 530 5 times, resulting in a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 7969.5
Subtract 490 from 530 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
98 can be fit into 400 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 7969.54
Subtracting 392 from 400 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
If we divide 80 by 98, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 7969.54
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
If we divide 800 by 98, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 7969.5408
Deduct 784 from 800 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
When dividing 160 by 98, we get 1 with a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 7969.54081
If we subtract 98 from 160, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 12:
98 goes into 620 6 times with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 7969.540816
The remainder is 32 after subtracting 588 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 13:
The number 98 fits into 320 3 times, leaving a remainder of 26.
The next digit of our result is 3. 
Result so far: 7969.5408163
The remainder is 26 after subtracting 294 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 14:
When dividing 260 by 98, we get 2 with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 7969.54081632
Deduct 196 from 260 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 7969.54081632, with a leftover of 6.4e-08.
