We divide 31945 by 98
The aim is to understand the frequency of 98 in 31945.

On to step 1:
The number 98 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 98

On to step 2:
98 can be fit into 31 0 times, resulting in a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Include the next digit (9) from the dividend after 31, then repeat: 319 / 98

Advancing to step 3:
98 can be fit into 319 3 times, resulting in a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 294 from 319, we get 25.
Include the next digit (4) from the dividend after 25, then repeat: 254 / 98

Moving on to step 4:
98 can be fit into 254 2 times, resulting in a remainder of 58.
The next digit of our result is 2. 
Result so far: 32.0
Deduct 196 from 254 and we're left with 58.
Grab the next digit (5) from the dividend, add it to 58, then carry on: 585 / 98

On to step 5:
If we divide 585 by 98, we get 5 and a remainder of 95.
Use 5 as the next digit of our solution. 
Result so far: 325.0
Subtract 490 from 585 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Let's proceed to step 6:
98 can be fit into 950 9 times, resulting in a remainder of 68.
The number 9 becomes the next digit in our result. 
Result so far: 325.9
If we subtract 882 from 950, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 7:
When dividing 680 by 98, we get 6 with a remainder of 92.
Record the quotient 6 as the next digit in the result. 
Result so far: 325.96
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.

On to step 8:
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: 325.969
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.

Let's proceed to step 9:
98 goes into 380 3 times with a remainder of 86.
Put 3 as the next digit of the answer. 
Result so far: 325.9693
If we take 294 away from 380, we end up 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.

On to step 10:
The number 98 fits into 860 8 times, leaving a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 325.96938
Subtract 784 from 860 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 11:
98 can be fit into 760 7 times, resulting in a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 325.969387
If we subtract 686 from 760, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 12:
98 can be fit into 740 7 times, resulting in a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 325.9693877
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 outcome is 325.9693877, with a leftover of 5.4e-07.
