We're dividing 86934926 by 866 
The aim is to understand the frequency of 866 in 86934926.

On to step 1:
8 divided by 866 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 866

Moving on to step 2:
866 can be fit into 86 0 times, resulting in a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Bring next digit (9) of the dividend behind the 86 and repeat the process: 869 / 866

Moving on to step 3:
869 divided by 866 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 866 from 869 and we're left with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 866

Let's proceed to step 4:
866 can be fit into 33 0 times, resulting in a remainder of 33.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 33, we get 33.
Include the next digit (4) from the dividend after 33, then repeat: 334 / 866

Step 5:
334 divided by 866 is 0 with a remainder of 334.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
Subtracting 0 from 334 leaves us with 334.
Take the next digit (9) from the dividend and append it to 334, then repeat: 3349 / 866

Let's proceed to step 6:
If we divide 3349 by 866, we get 3 and a remainder of 751.
Use 3 as the next digit of our solution. 
Result so far: 1003.0
Subtracting 2598 from 3349 leaves us with 751.
Grab the next digit (2) from the dividend, add it to 751, then carry on: 7512 / 866

Let's proceed to step 7:
The number 866 fits into 7512 8 times, leaving a remainder of 584.
Record the quotient 8 as the next digit in the result. 
Result so far: 10038.0
Subtract 6928 from 7512 to get 584.
Take the next digit (6) from the dividend and append it to 584, then repeat: 5846 / 866

Advancing to step 8:
If we divide 5846 by 866, we get 6 and a remainder of 650.
The next digit of our result is 6. 
Result so far: 100386.0
Subtract 5196 from 5846 to get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Let's proceed to step 9:
If we divide 6500 by 866, we get 7 and a remainder of 438.
Use 7 as the next digit of our solution. 
Result so far: 100386.7
If we subtract 6062 from 6500, we get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Step 10:
If we divide 4380 by 866, we get 5 and a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 100386.75
If we take 4330 away from 4380, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 11:
866 goes into 500 0 times with a remainder of 500.
Record the quotient 0 as the next digit in the result. 
Result so far: 100386.75
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 12:
The number 866 fits into 5000 5 times, leaving a remainder of 670.
Write down 5 as next digit of the result. 
Result so far: 100386.7505
Deduct 4330 from 5000 and we're left with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Step 13:
If we divide 6700 by 866, we get 7 and a remainder of 638.
The number 7 becomes the next digit in our result. 
Result so far: 100386.75057
Deduct 6062 from 6700 and we're left with 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Going ahead to step 14:
The number 866 fits into 6380 7 times, leaving a remainder of 318.
Use 7 as the next digit of our solution. 
Result so far: 100386.750577
The remainder is 318 after subtracting 6062 from 6380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Our division results in 100386.750577 with a remaining 3.18e-05.
