Let's divide 628249 by 88
The aim is to understand the frequency of 88 in 628249.

Advancing to step 1:
88 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 88

Going ahead to step 2:
If we divide 62 by 88, we get 0 and a remainder of 62.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 62 to get 62.
Bring next digit (8) of the dividend behind the 62 and repeat the process: 628 / 88

Advancing to step 3:
When dividing 628 by 88, we get 7 with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 12 after subtracting 616 from 628.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 88

On to step 4:
If we divide 122 by 88, we get 1 and a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 71.0
Deduct 88 from 122 and we're left with 34.
Grab the next digit (4) from the dividend, add it to 34, then carry on: 344 / 88

Moving on to step 5:
88 can be fit into 344 3 times, resulting in a remainder of 80.
Use 3 as the next digit of our solution. 
Result so far: 713.0
Subtracting 264 from 344 leaves us with 80.
Append the next digit (9) from the dividend to 80 and continue with: 809 / 88

Going ahead to step 6:
88 goes into 809 9 times with a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 7139.0
Subtract 792 from 809 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
The number 88 fits into 170 1 times, leaving a remainder of 82.
The next digit of our result is 1. 
Result so far: 7139.1
Subtracting 88 from 170 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 8:
The number 88 fits into 820 9 times, leaving a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 7139.19
Subtracting 792 from 820 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 9:
When dividing 280 by 88, we get 3 with a remainder of 16.
The next digit of our result is 3. 
Result so far: 7139.193
If we take 264 away from 280, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
160 divided by 88 is 1 with a remainder of 72.
Put 1 as the next digit of the answer. 
Result so far: 7139.1931
If we subtract 88 from 160, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 11:
When dividing 720 by 88, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 7139.19318
If we subtract 704 from 720, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
When dividing 160 by 88, we get 1 with a remainder of 72.
Write down 1 as next digit of the result. 
Result so far: 7139.193181
Subtract 88 from 160 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 13:
The number 88 fits into 720 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 7139.1931818
If we take 704 away from 720, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 14:
88 goes into 160 1 times with a remainder of 72.
Record the quotient 1 as the next digit in the result. 
Result so far: 7139.19318181
If we subtract 88 from 160, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

After the division, we end up with 7139.19318181 and a remainder of 7.2e-08.
