531170 divided by 98 
The aim is to understand the frequency of 98 in 531170.

On to step 1:
5 divided by 98 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 98

Going ahead to step 2:
53 divided by 98 is 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 53 to get 53.
Grab the next digit (1) from the dividend, add it to 53, then carry on: 531 / 98

Moving on to step 3:
When dividing 531 by 98, we get 5 with a remainder of 41.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 490 from 531 leaves us with 41.
Bring next digit (1) of the dividend behind the 41 and repeat the process: 411 / 98

Advancing to step 4:
411 divided by 98 is 4 with a remainder of 19.
Put 4 as the next digit of the answer. 
Result so far: 54.0
Subtracting 392 from 411 leaves us with 19.
Append the next digit (7) from the dividend to 19 and continue with: 197 / 98

On to step 5:
197 divided by 98 is 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 542.0
Subtract 196 from 197 to get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 98

Moving on to step 6:
98 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 5420.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
When dividing 100 by 98, we get 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 5420.1
If we subtract 98 from 100, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
20 divided by 98 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 5420.1
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
98 goes into 200 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 5420.102
If we take 196 away from 200, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
40 divided by 98 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 5420.102
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
The number 98 fits into 400 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 5420.10204
Subtract 392 from 400 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
The number 98 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 5420.10204
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.

Going ahead to step 13:
98 can be fit into 800 8 times, resulting in a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 5420.1020408
If we subtract 784 from 800, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
When dividing 160 by 98, we get 1 with a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 5420.10204081
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.

The final result is 5420.10204081 with a remainder of 6.2e-08.
