We look at the division of 87091695 by 653 
The aim is to understand the frequency of 653 in 87091695.

Going ahead to step 1:
The number 653 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 653

Step 2:
653 goes into 87 0 times with a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Take the next digit (0) from the dividend and append it to 87, then repeat: 870 / 653

Moving on to step 3:
870 divided by 653 is 1 with a remainder of 217.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 653 from 870 leaves us with 217.
Fetch the next digit (9) from the dividend, attach it to 217 and continue: 2179 / 653

Let's proceed to step 4:
2179 divided by 653 is 3 with a remainder of 220.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 1959 from 2179 to get 220.
Bring next digit (1) of the dividend behind the 220 and repeat the process: 2201 / 653

Let's proceed to step 5:
If we divide 2201 by 653, we get 3 and a remainder of 242.
Write down 3 as next digit of the result. 
Result so far: 133.0
If we take 1959 away from 2201, we end up with 242.
Fetch the next digit (6) from the dividend, attach it to 242 and continue: 2426 / 653

On to step 6:
653 can be fit into 2426 3 times, resulting in a remainder of 467.
The number 3 becomes the next digit in our result. 
Result so far: 1333.0
Deduct 1959 from 2426 and we're left with 467.
Take the next digit (9) from the dividend and append it to 467, then repeat: 4679 / 653

Moving on to step 7:
When dividing 4679 by 653, we get 7 with a remainder of 108.
Put 7 as the next digit of the answer. 
Result so far: 13337.0
If we take 4571 away from 4679, we end up with 108.
Fetch the next digit (5) from the dividend, attach it to 108 and continue: 1085 / 653

Moving on to step 8:
653 goes into 1085 1 times with a remainder of 432.
Put 1 as the next digit of the answer. 
Result so far: 133371.0
If we take 653 away from 1085, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

On to step 9:
4320 divided by 653 is 6 with a remainder of 402.
Write down 6 as next digit of the result. 
Result so far: 133371.6
If we subtract 3918 from 4320, we get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Going ahead to step 10:
4020 divided by 653 is 6 with a remainder of 102.
Record the quotient 6 as the next digit in the result. 
Result so far: 133371.66
Subtracting 3918 from 4020 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

The final outcome is 133371.66, with a leftover of 0.102.
