We're dividing 40135689 by 655 
The aim is to understand the frequency of 655 in 40135689.

Step 1:
When dividing 4 by 655, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 655

On to step 2:
40 divided by 655 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Grab the next digit (1) from the dividend, add it to 40, then carry on: 401 / 655

Going ahead to step 3:
401 divided by 655 is 0 with a remainder of 401.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 401, we get 401.
Bring next digit (3) of the dividend behind the 401 and repeat the process: 4013 / 655

Moving on to step 4:
655 goes into 4013 6 times with a remainder of 83.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 83 after subtracting 3930 from 4013.
Include the next digit (5) from the dividend after 83, then repeat: 835 / 655

Let's proceed to step 5:
The number 655 fits into 835 1 times, leaving a remainder of 180.
The next digit of our result is 1. 
Result so far: 61.0
If we subtract 655 from 835, we get 180.
Append the next digit (6) from the dividend to 180 and continue with: 1806 / 655

On to step 6:
655 can be fit into 1806 2 times, resulting in a remainder of 496.
The next digit of our result is 2. 
Result so far: 612.0
If we subtract 1310 from 1806, we get 496.
Include the next digit (8) from the dividend after 496, then repeat: 4968 / 655

Let's proceed to step 7:
The number 655 fits into 4968 7 times, leaving a remainder of 383.
Use 7 as the next digit of our solution. 
Result so far: 6127.0
If we take 4585 away from 4968, we end up with 383.
Bring next digit (9) of the dividend behind the 383 and repeat the process: 3839 / 655

Step 8:
655 goes into 3839 5 times with a remainder of 564.
Use 5 as the next digit of our solution. 
Result so far: 61275.0
Deduct 3275 from 3839 and we're left with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Moving on to step 9:
655 can be fit into 5640 8 times, resulting in a remainder of 400.
Put 8 as the next digit of the answer. 
Result so far: 61275.8
If we subtract 5240 from 5640, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 10:
4000 divided by 655 is 6 with a remainder of 70.
The next digit of our result is 6. 
Result so far: 61275.86
Deduct 3930 from 4000 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 11:
If we divide 700 by 655, we get 1 and a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 61275.861
The remainder is 45 after subtracting 655 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 12:
The number 655 fits into 450 0 times, leaving a remainder of 450.
Write down 0 as next digit of the result. 
Result so far: 61275.861
If we subtract 0 from 450, we get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 13:
If we divide 4500 by 655, we get 6 and a remainder of 570.
The number 6 becomes the next digit in our result. 
Result so far: 61275.86106
Deduct 3930 from 4500 and we're left with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Advancing to step 14:
655 goes into 5700 8 times with a remainder of 460.
Write down 8 as next digit of the result. 
Result so far: 61275.861068
If we take 5240 away from 5700, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Let's proceed to step 15:
4600 divided by 655 is 7 with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 61275.8610687
Deduct 4585 from 4600 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 16:
150 divided by 655 is 0 with a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 61275.8610687
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The quotient of the division is 61275.8610687, and the remainder is 1.5e-07.
