We divide 88806643 by 646
The aim is to understand the frequency of 646 in 88806643.

Going ahead to step 1:
If we divide 8 by 646, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 646

Going ahead to step 2:
The number 646 fits into 88 0 times, leaving a remainder of 88.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 88, we end up with 88.
Take the next digit (8) from the dividend and append it to 88, then repeat: 888 / 646

Going ahead to step 3:
The number 646 fits into 888 1 times, leaving a remainder of 242.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 646 away from 888, we end up with 242.
Fetch the next digit (0) from the dividend, attach it to 242 and continue: 2420 / 646

Advancing to step 4:
646 goes into 2420 3 times with a remainder of 482.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 1938 from 2420 to get 482.
Include the next digit (6) from the dividend after 482, then repeat: 4826 / 646

Step 5:
If we divide 4826 by 646, we get 7 and a remainder of 304.
The number 7 becomes the next digit in our result. 
Result so far: 137.0
Deduct 4522 from 4826 and we're left with 304.
Take the next digit (6) from the dividend and append it to 304, then repeat: 3046 / 646

Step 6:
646 can be fit into 3046 4 times, resulting in a remainder of 462.
The number 4 becomes the next digit in our result. 
Result so far: 1374.0
Subtracting 2584 from 3046 leaves us with 462.
Take the next digit (4) from the dividend and append it to 462, then repeat: 4624 / 646

Going ahead to step 7:
646 can be fit into 4624 7 times, resulting in a remainder of 102.
Use 7 as the next digit of our solution. 
Result so far: 13747.0
Subtracting 4522 from 4624 leaves us with 102.
Include the next digit (3) from the dividend after 102, then repeat: 1023 / 646

Step 8:
When dividing 1023 by 646, we get 1 with a remainder of 377.
Put 1 as the next digit of the answer. 
Result so far: 137471.0
If we take 646 away from 1023, we end up with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Advancing to step 9:
3770 divided by 646 is 5 with a remainder of 540.
The number 5 becomes the next digit in our result. 
Result so far: 137471.5
If we subtract 3230 from 3770, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Step 10:
If we divide 5400 by 646, we get 8 and a remainder of 232.
Put 8 as the next digit of the answer. 
Result so far: 137471.58
The remainder is 232 after subtracting 5168 from 5400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 11:
2320 divided by 646 is 3 with a remainder of 382.
Write down 3 as next digit of the result. 
Result so far: 137471.583
Subtracting 1938 from 2320 leaves us with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Moving on to step 12:
646 goes into 3820 5 times with a remainder of 590.
Use 5 as the next digit of our solution. 
Result so far: 137471.5835
If we take 3230 away from 3820, we end up with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Going ahead to step 13:
5900 divided by 646 is 9 with a remainder of 86.
Put 9 as the next digit of the answer. 
Result so far: 137471.58359
Deduct 5814 from 5900 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Let's proceed to step 14:
860 divided by 646 is 1 with a remainder of 214.
Write down 1 as next digit of the result. 
Result so far: 137471.583591
If we subtract 646 from 860, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

On to step 15:
646 goes into 2140 3 times with a remainder of 202.
The next digit of our result is 3. 
Result so far: 137471.5835913
If we take 1938 away from 2140, we end up with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Let's proceed to step 16:
The number 646 fits into 2020 3 times, leaving a remainder of 82.
Use 3 as the next digit of our solution. 
Result so far: 137471.58359133
Subtract 1938 from 2020 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Our division results in 137471.58359133 with a remaining 8.2e-08.
