97440408 ÷ 654 
The aim is to understand the frequency of 654 in 97440408.

Advancing to step 1:
9 divided by 654 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 654

Step 2:
654 goes into 97 0 times with a remainder of 97.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 97 and we're left with 97.
Take the next digit (4) from the dividend and append it to 97, then repeat: 974 / 654

Step 3:
If we divide 974 by 654, we get 1 and a remainder of 320.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 654 from 974, we get 320.
Take the next digit (4) from the dividend and append it to 320, then repeat: 3204 / 654

Moving on to step 4:
654 can be fit into 3204 4 times, resulting in a remainder of 588.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we subtract 2616 from 3204, we get 588.
Fetch the next digit (0) from the dividend, attach it to 588 and continue: 5880 / 654

Going ahead to step 5:
When dividing 5880 by 654, we get 8 with a remainder of 648.
The number 8 becomes the next digit in our result. 
Result so far: 148.0
If we take 5232 away from 5880, we end up with 648.
Include the next digit (4) from the dividend after 648, then repeat: 6484 / 654

Advancing to step 6:
If we divide 6484 by 654, we get 9 and a remainder of 598.
Put 9 as the next digit of the answer. 
Result so far: 1489.0
Subtract 5886 from 6484 to get 598.
Grab the next digit (0) from the dividend, add it to 598, then carry on: 5980 / 654

Moving on to step 7:
5980 divided by 654 is 9 with a remainder of 94.
The number 9 becomes the next digit in our result. 
Result so far: 14899.0
Deduct 5886 from 5980 and we're left with 94.
Fetch the next digit (8) from the dividend, attach it to 94 and continue: 948 / 654

Going ahead to step 8:
654 can be fit into 948 1 times, resulting in a remainder of 294.
Record the quotient 1 as the next digit in the result. 
Result so far: 148991.0
Deduct 654 from 948 and we're left with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Going ahead to step 9:
2940 divided by 654 is 4 with a remainder of 324.
Use 4 as the next digit of our solution. 
Result so far: 148991.4
If we subtract 2616 from 2940, we get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Advancing to step 10:
The number 654 fits into 3240 4 times, leaving a remainder of 624.
The number 4 becomes the next digit in our result. 
Result so far: 148991.44
Subtract 2616 from 3240 to get 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

The quotient of the division is 148991.44, and the remainder is 0.624.
