We look at the division of 97117690 by 403 
The aim is to understand the frequency of 403 in 97117690.

Step 1:
The number 403 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 403

Going ahead to step 2:
When dividing 97 by 403, we get 0 with a remainder of 97.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 97 leaves us with 97.
Grab the next digit (1) from the dividend, add it to 97, then carry on: 971 / 403

Moving on to step 3:
403 goes into 971 2 times with a remainder of 165.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 806 from 971 to get 165.
Include the next digit (1) from the dividend after 165, then repeat: 1651 / 403

Let's proceed to step 4:
403 can be fit into 1651 4 times, resulting in a remainder of 39.
Put 4 as the next digit of the answer. 
Result so far: 24.0
The remainder is 39 after subtracting 1612 from 1651.
Fetch the next digit (7) from the dividend, attach it to 39 and continue: 397 / 403

Step 5:
397 divided by 403 is 0 with a remainder of 397.
Record the quotient 0 as the next digit in the result. 
Result so far: 240.0
If we take 0 away from 397, we end up with 397.
Append the next digit (6) from the dividend to 397 and continue with: 3976 / 403

On to step 6:
403 goes into 3976 9 times with a remainder of 349.
Use 9 as the next digit of our solution. 
Result so far: 2409.0
If we take 3627 away from 3976, we end up with 349.
Grab the next digit (9) from the dividend, add it to 349, then carry on: 3499 / 403

Going ahead to step 7:
3499 divided by 403 is 8 with a remainder of 275.
Record the quotient 8 as the next digit in the result. 
Result so far: 24098.0
If we subtract 3224 from 3499, we get 275.
Include the next digit (0) from the dividend after 275, then repeat: 2750 / 403

Let's proceed to step 8:
403 goes into 2750 6 times with a remainder of 332.
Write down 6 as next digit of the result. 
Result so far: 240986.0
If we subtract 2418 from 2750, we get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Step 9:
If we divide 3320 by 403, we get 8 and a remainder of 96.
The number 8 becomes the next digit in our result. 
Result so far: 240986.8
If we take 3224 away from 3320, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 10:
The number 403 fits into 960 2 times, leaving a remainder of 154.
Use 2 as the next digit of our solution. 
Result so far: 240986.82
The remainder is 154 after subtracting 806 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Going ahead to step 11:
403 goes into 1540 3 times with a remainder of 331.
Use 3 as the next digit of our solution. 
Result so far: 240986.823
If we subtract 1209 from 1540, we get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Moving on to step 12:
403 goes into 3310 8 times with a remainder of 86.
The number 8 becomes the next digit in our result. 
Result so far: 240986.8238
Subtracting 3224 from 3310 leaves us 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.

Going ahead to step 13:
When dividing 860 by 403, we get 2 with a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 240986.82382
Subtracting 806 from 860 leaves us 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.

Going ahead to step 14:
When dividing 540 by 403, we get 1 with a remainder of 137.
The next digit of our result is 1. 
Result so far: 240986.823821
Deduct 403 from 540 and we're left with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Going ahead to step 15:
The number 403 fits into 1370 3 times, leaving a remainder of 161.
Write down 3 as next digit of the result. 
Result so far: 240986.8238213
If we take 1209 away from 1370, we end up with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Advancing to step 16:
1610 divided by 403 is 3 with a remainder of 401.
The number 3 becomes the next digit in our result. 
Result so far: 240986.82382133
If we take 1209 away from 1610, we end up with 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

After the division, we end up with 240986.82382133 and a remainder of 4.01e-07.
