88767993 ÷ 669 
The aim is to understand the frequency of 669 in 88767993.

Let's proceed to step 1:
669 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 669

On to step 2:
88 divided by 669 is 0 with a remainder of 88.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 88 leaves us with 88.
Take the next digit (7) from the dividend and append it to 88, then repeat: 887 / 669

Moving on to step 3:
The number 669 fits into 887 1 times, leaving a remainder of 218.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 669 from 887 leaves us with 218.
Include the next digit (6) from the dividend after 218, then repeat: 2186 / 669

Advancing to step 4:
When dividing 2186 by 669, we get 3 with a remainder of 179.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 2007 from 2186 to get 179.
Grab the next digit (7) from the dividend, add it to 179, then carry on: 1797 / 669

Advancing to step 5:
1797 divided by 669 is 2 with a remainder of 459.
Record the quotient 2 as the next digit in the result. 
Result so far: 132.0
Subtracting 1338 from 1797 leaves us with 459.
Bring next digit (9) of the dividend behind the 459 and repeat the process: 4599 / 669

Moving on to step 6:
669 can be fit into 4599 6 times, resulting in a remainder of 585.
Use 6 as the next digit of our solution. 
Result so far: 1326.0
If we subtract 4014 from 4599, we get 585.
Include the next digit (9) from the dividend after 585, then repeat: 5859 / 669

Advancing to step 7:
669 goes into 5859 8 times with a remainder of 507.
Write down 8 as next digit of the result. 
Result so far: 13268.0
If we subtract 5352 from 5859, we get 507.
Bring next digit (3) of the dividend behind the 507 and repeat the process: 5073 / 669

Step 8:
If we divide 5073 by 669, we get 7 and a remainder of 390.
Write down 7 as next digit of the result. 
Result so far: 132687.0
Subtract 4683 from 5073 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 9:
669 goes into 3900 5 times with a remainder of 555.
The number 5 becomes the next digit in our result. 
Result so far: 132687.5
Deduct 3345 from 3900 and we're left with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Moving on to step 10:
The number 669 fits into 5550 8 times, leaving a remainder of 198.
The number 8 becomes the next digit in our result. 
Result so far: 132687.58
Deduct 5352 from 5550 and we're left with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Step 11:
669 can be fit into 1980 2 times, resulting in a remainder of 642.
Use 2 as the next digit of our solution. 
Result so far: 132687.582
If we take 1338 away from 1980, we end up with 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

Let's proceed to step 12:
If we divide 6420 by 669, we get 9 and a remainder of 399.
Put 9 as the next digit of the answer. 
Result so far: 132687.5829
The remainder is 399 after subtracting 6021 from 6420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Moving on to step 13:
669 can be fit into 3990 5 times, resulting in a remainder of 645.
Write down 5 as next digit of the result. 
Result so far: 132687.58295
If we subtract 3345 from 3990, we get 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

Moving on to step 14:
6450 divided by 669 is 9 with a remainder of 429.
Use 9 as the next digit of our solution. 
Result so far: 132687.582959
Subtracting 6021 from 6450 leaves us with 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Let's proceed to step 15:
4290 divided by 669 is 6 with a remainder of 276.
The number 6 becomes the next digit in our result. 
Result so far: 132687.5829596
The remainder is 276 after subtracting 4014 from 4290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Moving on to step 16:
669 can be fit into 2760 4 times, resulting in a remainder of 84.
Put 4 as the next digit of the answer. 
Result so far: 132687.58295964
If we take 2676 away from 2760, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

In conclusion, the division gives 132687.58295964 with a balance of 8.4e-08.
