161979 divided by 98 
The aim is to understand the frequency of 98 in 161979.

Let's proceed to step 1:
1 divided by 98 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 98

Advancing to step 2:
The number 98 fits into 16 0 times, leaving a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 98

Advancing to step 3:
98 can be fit into 161 1 times, resulting in a remainder of 63.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 98 from 161, we get 63.
Grab the next digit (9) from the dividend, add it to 63, then carry on: 639 / 98

Going ahead to step 4:
If we divide 639 by 98, we get 6 and a remainder of 51.
Write down 6 as next digit of the result. 
Result so far: 16.0
Deduct 588 from 639 and we're left with 51.
Fetch the next digit (7) from the dividend, attach it to 51 and continue: 517 / 98

Going ahead to step 5:
If we divide 517 by 98, we get 5 and a remainder of 27.
Use 5 as the next digit of our solution. 
Result so far: 165.0
Subtracting 490 from 517 leaves us with 27.
Grab the next digit (9) from the dividend, add it to 27, then carry on: 279 / 98

Moving on to step 6:
When dividing 279 by 98, we get 2 with a remainder of 83.
The next digit of our result is 2. 
Result so far: 1652.0
If we take 196 away from 279, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 7:
98 goes into 830 8 times with a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 1652.8
The remainder is 46 after subtracting 784 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 8:
460 divided by 98 is 4 with a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 1652.84
The remainder is 68 after subtracting 392 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 9:
The number 98 fits into 680 6 times, leaving a remainder of 92.
The next digit of our result is 6. 
Result so far: 1652.846
If we take 588 away from 680, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 10:
98 can be fit into 920 9 times, resulting in a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 1652.8469
If we subtract 882 from 920, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 11:
380 divided by 98 is 3 with a remainder of 86.
The next digit of our result is 3. 
Result so far: 1652.84693
Deduct 294 from 380 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 12:
The number 98 fits into 860 8 times, leaving a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 1652.846938
Deduct 784 from 860 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 13:
The number 98 fits into 760 7 times, leaving a remainder of 74.
The number 7 becomes the next digit in our result. 
Result so far: 1652.8469387
Deduct 686 from 760 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 14:
98 goes into 740 7 times with a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 1652.84693877
Deduct 686 from 740 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 1652.84693877 with a remainder of 5.4e-08.
