We look at the division of 63958093 by 654 
The aim is to understand the frequency of 654 in 63958093.

Step 1:
The number 654 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 654

Going ahead to step 2:
63 divided by 654 is 0 with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 654

Let's proceed to step 3:
If we divide 639 by 654, we get 0 and a remainder of 639.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 639 and we're left with 639.
Include the next digit (5) from the dividend after 639, then repeat: 6395 / 654

Moving on to step 4:
If we divide 6395 by 654, we get 9 and a remainder of 509.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 5886 from 6395 to get 509.
Bring next digit (8) of the dividend behind the 509 and repeat the process: 5098 / 654

Advancing to step 5:
If we divide 5098 by 654, we get 7 and a remainder of 520.
Put 7 as the next digit of the answer. 
Result so far: 97.0
Subtract 4578 from 5098 to get 520.
Grab the next digit (0) from the dividend, add it to 520, then carry on: 5200 / 654

Step 6:
When dividing 5200 by 654, we get 7 with a remainder of 622.
Write down 7 as next digit of the result. 
Result so far: 977.0
The remainder is 622 after subtracting 4578 from 5200.
Append the next digit (9) from the dividend to 622 and continue with: 6229 / 654

On to step 7:
When dividing 6229 by 654, we get 9 with a remainder of 343.
Record the quotient 9 as the next digit in the result. 
Result so far: 9779.0
If we take 5886 away from 6229, we end up with 343.
Take the next digit (3) from the dividend and append it to 343, then repeat: 3433 / 654

Step 8:
654 goes into 3433 5 times with a remainder of 163.
The next digit of our result is 5. 
Result so far: 97795.0
Subtract 3270 from 3433 to get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Step 9:
1630 divided by 654 is 2 with a remainder of 322.
Write down 2 as next digit of the result. 
Result so far: 97795.2
The remainder is 322 after subtracting 1308 from 1630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Moving on to step 10:
When dividing 3220 by 654, we get 4 with a remainder of 604.
Put 4 as the next digit of the answer. 
Result so far: 97795.24
If we take 2616 away from 3220, we end up with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Going ahead to step 11:
654 goes into 6040 9 times with a remainder of 154.
The number 9 becomes the next digit in our result. 
Result so far: 97795.249
Deduct 5886 from 6040 and we're left with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Advancing to step 12:
If we divide 1540 by 654, we get 2 and a remainder of 232.
Record the quotient 2 as the next digit in the result. 
Result so far: 97795.2492
The remainder is 232 after subtracting 1308 from 1540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 13:
If we divide 2320 by 654, we get 3 and a remainder of 358.
Put 3 as the next digit of the answer. 
Result so far: 97795.24923
If we subtract 1962 from 2320, we get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Let's proceed to step 14:
654 can be fit into 3580 5 times, resulting in a remainder of 310.
The next digit of our result is 5. 
Result so far: 97795.249235
Subtracting 3270 from 3580 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 15:
If we divide 3100 by 654, we get 4 and a remainder of 484.
The next digit of our result is 4. 
Result so far: 97795.2492354
Deduct 2616 from 3100 and we're left with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Going ahead to step 16:
4840 divided by 654 is 7 with a remainder of 262.
The number 7 becomes the next digit in our result. 
Result so far: 97795.24923547
Deduct 4578 from 4840 and we're left with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

In conclusion, the division gives 97795.24923547 with a balance of 2.62e-07.
