Let's divide 604721 by 88
The aim is to understand the frequency of 88 in 604721.

Let's proceed to step 1:
88 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 88

On to step 2:
When dividing 60 by 88, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 60, we end up with 60.
Append the next digit (4) from the dividend to 60 and continue with: 604 / 88

Let's proceed to step 3:
When dividing 604 by 88, we get 6 with a remainder of 76.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 76 after subtracting 528 from 604.
Bring next digit (7) of the dividend behind the 76 and repeat the process: 767 / 88

On to step 4:
767 divided by 88 is 8 with a remainder of 63.
Write down 8 as next digit of the result. 
Result so far: 68.0
If we subtract 704 from 767, we get 63.
Append the next digit (2) from the dividend to 63 and continue with: 632 / 88

Advancing to step 5:
The number 88 fits into 632 7 times, leaving a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 687.0
The remainder is 16 after subtracting 616 from 632.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 88

Going ahead to step 6:
The number 88 fits into 161 1 times, leaving a remainder of 73.
The next digit of our result is 1. 
Result so far: 6871.0
Deduct 88 from 161 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 7:
88 can be fit into 730 8 times, resulting in a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 6871.8
If we subtract 704 from 730, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 8:
88 can be fit into 260 2 times, resulting in a remainder of 84.
The number 2 becomes the next digit in our result. 
Result so far: 6871.82
Subtract 176 from 260 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 9:
88 goes into 840 9 times with a remainder of 48.
Record the quotient 9 as the next digit in the result. 
Result so far: 6871.829
Deduct 792 from 840 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 10:
480 divided by 88 is 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 6871.8295
Deduct 440 from 480 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
400 divided by 88 is 4 with a remainder of 48.
The next digit of our result is 4. 
Result so far: 6871.82954
The remainder is 48 after subtracting 352 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 12:
88 goes into 480 5 times with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 6871.829545
Subtract 440 from 480 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
400 divided by 88 is 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 6871.8295454
Subtracting 352 from 400 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 14:
If we divide 480 by 88, we get 5 and a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 6871.82954545
Deduct 440 from 480 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 6871.82954545 and a remainder of 4e-08.
