88219882 divided by 646 
The aim is to understand the frequency of 646 in 88219882.

Moving on to step 1:
When dividing 8 by 646, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 646

Advancing to step 2:
88 divided by 646 is 0 with a remainder of 88.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 88 leaves us with 88.
Fetch the next digit (2) from the dividend, attach it to 88 and continue: 882 / 646

On to step 3:
When dividing 882 by 646, we get 1 with a remainder of 236.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 646 from 882 and we're left with 236.
Bring next digit (1) of the dividend behind the 236 and repeat the process: 2361 / 646

Step 4:
646 can be fit into 2361 3 times, resulting in a remainder of 423.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 423 after subtracting 1938 from 2361.
Take the next digit (9) from the dividend and append it to 423, then repeat: 4239 / 646

Step 5:
If we divide 4239 by 646, we get 6 and a remainder of 363.
Use 6 as the next digit of our solution. 
Result so far: 136.0
Subtract 3876 from 4239 to get 363.
Fetch the next digit (8) from the dividend, attach it to 363 and continue: 3638 / 646

Let's proceed to step 6:
646 goes into 3638 5 times with a remainder of 408.
Use 5 as the next digit of our solution. 
Result so far: 1365.0
If we take 3230 away from 3638, we end up with 408.
Include the next digit (8) from the dividend after 408, then repeat: 4088 / 646

Step 7:
If we divide 4088 by 646, we get 6 and a remainder of 212.
The number 6 becomes the next digit in our result. 
Result so far: 13656.0
Subtracting 3876 from 4088 leaves us with 212.
Grab the next digit (2) from the dividend, add it to 212, then carry on: 2122 / 646

Let's proceed to step 8:
646 can be fit into 2122 3 times, resulting in a remainder of 184.
Write down 3 as next digit of the result. 
Result so far: 136563.0
Subtract 1938 from 2122 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 9:
1840 divided by 646 is 2 with a remainder of 548.
Write down 2 as next digit of the result. 
Result so far: 136563.2
Subtracting 1292 from 1840 leaves us with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Going ahead to step 10:
5480 divided by 646 is 8 with a remainder of 312.
Record the quotient 8 as the next digit in the result. 
Result so far: 136563.28
Subtracting 5168 from 5480 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Moving on to step 11:
The number 646 fits into 3120 4 times, leaving a remainder of 536.
The number 4 becomes the next digit in our result. 
Result so far: 136563.284
The remainder is 536 after subtracting 2584 from 3120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Going ahead to step 12:
5360 divided by 646 is 8 with a remainder of 192.
Write down 8 as next digit of the result. 
Result so far: 136563.2848
Subtract 5168 from 5360 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 13:
If we divide 1920 by 646, we get 2 and a remainder of 628.
The next digit of our result is 2. 
Result so far: 136563.28482
Subtract 1292 from 1920 to get 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Advancing to step 14:
The number 646 fits into 6280 9 times, leaving a remainder of 466.
The next digit of our result is 9. 
Result so far: 136563.284829
If we subtract 5814 from 6280, we get 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Step 15:
The number 646 fits into 4660 7 times, leaving a remainder of 138.
The number 7 becomes the next digit in our result. 
Result so far: 136563.2848297
Subtract 4522 from 4660 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Going ahead to step 16:
When dividing 1380 by 646, we get 2 with a remainder of 88.
Write down 2 as next digit of the result. 
Result so far: 136563.28482972
Deduct 1292 from 1380 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The quotient of the division is 136563.28482972, and the remainder is 8.8e-08.
