86506620 divided by 626 
The aim is to understand the frequency of 626 in 86506620.

Let's proceed to step 1:
626 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 626

Advancing to step 2:
626 goes into 86 0 times with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Take the next digit (5) from the dividend and append it to 86, then repeat: 865 / 626

Moving on to step 3:
865 divided by 626 is 1 with a remainder of 239.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 626 from 865 leaves us with 239.
Grab the next digit (0) from the dividend, add it to 239, then carry on: 2390 / 626

Going ahead to step 4:
When dividing 2390 by 626, we get 3 with a remainder of 512.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 1878 from 2390, we get 512.
Fetch the next digit (6) from the dividend, attach it to 512 and continue: 5126 / 626

Advancing to step 5:
626 can be fit into 5126 8 times, resulting in a remainder of 118.
Write down 8 as next digit of the result. 
Result so far: 138.0
If we subtract 5008 from 5126, we get 118.
Include the next digit (6) from the dividend after 118, then repeat: 1186 / 626

Advancing to step 6:
626 can be fit into 1186 1 times, resulting in a remainder of 560.
Use 1 as the next digit of our solution. 
Result so far: 1381.0
The remainder is 560 after subtracting 626 from 1186.
Bring next digit (2) of the dividend behind the 560 and repeat the process: 5602 / 626

Going ahead to step 7:
If we divide 5602 by 626, we get 8 and a remainder of 594.
Record the quotient 8 as the next digit in the result. 
Result so far: 13818.0
If we take 5008 away from 5602, we end up with 594.
Grab the next digit (0) from the dividend, add it to 594, then carry on: 5940 / 626

On to step 8:
626 goes into 5940 9 times with a remainder of 306.
Write down 9 as next digit of the result. 
Result so far: 138189.0
Subtract 5634 from 5940 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

On to step 9:
The number 626 fits into 3060 4 times, leaving a remainder of 556.
The next digit of our result is 4. 
Result so far: 138189.4
If we subtract 2504 from 3060, we get 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

On to step 10:
626 goes into 5560 8 times with a remainder of 552.
Put 8 as the next digit of the answer. 
Result so far: 138189.48
Subtracting 5008 from 5560 leaves us with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Step 11:
If we divide 5520 by 626, we get 8 and a remainder of 512.
The number 8 becomes the next digit in our result. 
Result so far: 138189.488
If we subtract 5008 from 5520, we get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

After the division, we end up with 138189.488 and a remainder of 0.0512.
