We divide 621873 by 88
The aim is to understand the frequency of 88 in 621873.

Going ahead to step 1:
When dividing 6 by 88, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 88

Advancing to step 2:
If we divide 62 by 88, we get 0 and a remainder of 62.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 62, we get 62.
Take the next digit (1) from the dividend and append it to 62, then repeat: 621 / 88

Advancing to step 3:
The number 88 fits into 621 7 times, leaving a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 616 from 621 and we're left with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 88

Moving on to step 4:
When dividing 58 by 88, we get 0 with a remainder of 58.
Write down 0 as next digit of the result. 
Result so far: 70.0
The remainder is 58 after subtracting 0 from 58.
Fetch the next digit (7) from the dividend, attach it to 58 and continue: 587 / 88

Step 5:
88 goes into 587 6 times with a remainder of 59.
Put 6 as the next digit of the answer. 
Result so far: 706.0
If we take 528 away from 587, we end up with 59.
Take the next digit (3) from the dividend and append it to 59, then repeat: 593 / 88

On to step 6:
88 can be fit into 593 6 times, resulting in a remainder of 65.
The next digit of our result is 6. 
Result so far: 7066.0
Deduct 528 from 593 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 7:
The number 88 fits into 650 7 times, leaving a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 7066.7
If we subtract 616 from 650, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
If we divide 340 by 88, we get 3 and a remainder of 76.
Write down 3 as next digit of the result. 
Result so far: 7066.73
Subtracting 264 from 340 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 9:
760 divided by 88 is 8 with a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 7066.738
Subtracting 704 from 760 leaves us 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.

Let's proceed to step 10:
560 divided by 88 is 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 7066.7386
If we subtract 528 from 560, we 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 11:
88 can be fit into 320 3 times, resulting in a remainder of 56.
Use 3 as the next digit of our solution. 
Result so far: 7066.73863
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.

On to step 12:
88 can be fit into 560 6 times, resulting in a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 7066.738636
Deduct 528 from 560 and we're left 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 13:
When dividing 320 by 88, we get 3 with a remainder of 56.
Put 3 as the next digit of the answer. 
Result so far: 7066.7386363
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.

Moving on to step 14:
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: 7066.73863636
Deduct 528 from 560 and we're left 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.

In conclusion, the division gives 7066.73863636 with a balance of 3.2e-08.
