We're dividing 621996 by 88 
The aim is to understand the frequency of 88 in 621996.

On to step 1:
88 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 88

Moving on to step 2:
62 divided by 88 is 0 with a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 62 leaves us with 62.
Append the next digit (1) from the dividend to 62 and continue with: 621 / 88

Step 3:
When dividing 621 by 88, we get 7 with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 616 from 621 and we're left with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 88

Moving on to step 4:
88 can be fit into 59 0 times, resulting in a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
If we subtract 0 from 59, we get 59.
Append the next digit (9) from the dividend to 59 and continue with: 599 / 88

Advancing to step 5:
When dividing 599 by 88, we get 6 with a remainder of 71.
Record the quotient 6 as the next digit in the result. 
Result so far: 706.0
Deduct 528 from 599 and we're left with 71.
Include the next digit (6) from the dividend after 71, then repeat: 716 / 88

Step 6:
88 goes into 716 8 times with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 7068.0
If we subtract 704 from 716, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
120 divided by 88 is 1 with a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 7068.1
The remainder is 32 after subtracting 88 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 8:
320 divided by 88 is 3 with a remainder of 56.
Write down 3 as next digit of the result. 
Result so far: 7068.13
If we subtract 264 from 320, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 9:
When dividing 560 by 88, we get 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 7068.136
If we take 528 away from 560, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
If we divide 320 by 88, we get 3 and a remainder of 56.
The number 3 becomes the next digit in our result. 
Result so far: 7068.1363
Deduct 264 from 320 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 11:
When dividing 560 by 88, we get 6 with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 7068.13636
The remainder is 32 after subtracting 528 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
When dividing 320 by 88, we get 3 with a remainder of 56.
The number 3 becomes the next digit in our result. 
Result so far: 7068.136363
The remainder is 56 after subtracting 264 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 13:
88 can be fit into 560 6 times, resulting in a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 7068.1363636
Subtract 528 from 560 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 14:
320 divided by 88 is 3 with a remainder of 56.
Record the quotient 3 as the next digit in the result. 
Result so far: 7068.13636363
Subtract 264 from 320 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The quotient of the division is 7068.13636363, and the remainder is 5.6e-08.
