We look at the division of 21925920 by 655 
The aim is to understand the frequency of 655 in 21925920.

Step 1:
The number 655 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 655

Moving on to step 2:
21 divided by 655 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 655

Let's proceed to step 3:
655 can be fit into 219 0 times, resulting in a remainder of 219.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 219 after subtracting 0 from 219.
Grab the next digit (2) from the dividend, add it to 219, then carry on: 2192 / 655

Advancing to step 4:
655 goes into 2192 3 times with a remainder of 227.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 1965 from 2192 and we're left with 227.
Take the next digit (5) from the dividend and append it to 227, then repeat: 2275 / 655

Step 5:
655 goes into 2275 3 times with a remainder of 310.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Subtracting 1965 from 2275 leaves us with 310.
Take the next digit (9) from the dividend and append it to 310, then repeat: 3109 / 655

Advancing to step 6:
If we divide 3109 by 655, we get 4 and a remainder of 489.
The next digit of our result is 4. 
Result so far: 334.0
The remainder is 489 after subtracting 2620 from 3109.
Grab the next digit (2) from the dividend, add it to 489, then carry on: 4892 / 655

Let's proceed to step 7:
655 can be fit into 4892 7 times, resulting in a remainder of 307.
Write down 7 as next digit of the result. 
Result so far: 3347.0
Subtracting 4585 from 4892 leaves us with 307.
Fetch the next digit (0) from the dividend, attach it to 307 and continue: 3070 / 655

Advancing to step 8:
655 goes into 3070 4 times with a remainder of 450.
Use 4 as the next digit of our solution. 
Result so far: 33474.0
If we take 2620 away from 3070, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Going ahead to step 9:
655 can be fit into 4500 6 times, resulting in a remainder of 570.
The next digit of our result is 6. 
Result so far: 33474.6
If we subtract 3930 from 4500, we get 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 10:
655 goes into 5700 8 times with a remainder of 460.
Record the quotient 8 as the next digit in the result. 
Result so far: 33474.68
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.

Going ahead to step 11:
655 goes into 4600 7 times with a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 33474.687
If we take 4585 away from 4600, we end up 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.

Going ahead to step 12:
150 divided by 655 is 0 with a remainder of 150.
The next digit of our result is 0. 
Result so far: 33474.687
The remainder is 150 after subtracting 0 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 13:
1500 divided by 655 is 2 with a remainder of 190.
The next digit of our result is 2. 
Result so far: 33474.68702
If we take 1310 away from 1500, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 14:
655 can be fit into 1900 2 times, resulting in a remainder of 590.
The next digit of our result is 2. 
Result so far: 33474.687022
Subtract 1310 from 1900 to get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

After the division, we end up with 33474.687022 and a remainder of 5.9e-05.
