28399191 ÷ 867 
The aim is to understand the frequency of 867 in 28399191.

Moving on to step 1:
When dividing 2 by 867, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 867

Moving on to step 2:
The number 867 fits into 28 0 times, leaving a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Fetch the next digit (3) from the dividend, attach it to 28 and continue: 283 / 867

Step 3:
283 divided by 867 is 0 with a remainder of 283.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 283, we get 283.
Take the next digit (9) from the dividend and append it to 283, then repeat: 2839 / 867

Moving on to step 4:
2839 divided by 867 is 3 with a remainder of 238.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 2601 from 2839 leaves us with 238.
Fetch the next digit (9) from the dividend, attach it to 238 and continue: 2389 / 867

Step 5:
When dividing 2389 by 867, we get 2 with a remainder of 655.
The next digit of our result is 2. 
Result so far: 32.0
The remainder is 655 after subtracting 1734 from 2389.
Append the next digit (1) from the dividend to 655 and continue with: 6551 / 867

Going ahead to step 6:
If we divide 6551 by 867, we get 7 and a remainder of 482.
The number 7 becomes the next digit in our result. 
Result so far: 327.0
Deduct 6069 from 6551 and we're left with 482.
Fetch the next digit (9) from the dividend, attach it to 482 and continue: 4829 / 867

Step 7:
867 can be fit into 4829 5 times, resulting in a remainder of 494.
The number 5 becomes the next digit in our result. 
Result so far: 3275.0
If we take 4335 away from 4829, we end up with 494.
Bring next digit (1) of the dividend behind the 494 and repeat the process: 4941 / 867

On to step 8:
867 can be fit into 4941 5 times, resulting in a remainder of 606.
Record the quotient 5 as the next digit in the result. 
Result so far: 32755.0
If we take 4335 away from 4941, we end up with 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Going ahead to step 9:
The number 867 fits into 6060 6 times, leaving a remainder of 858.
Record the quotient 6 as the next digit in the result. 
Result so far: 32755.6
Deduct 5202 from 6060 and we're left with 858.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8580, and continue the process.

Moving on to step 10:
867 goes into 8580 9 times with a remainder of 777.
Record the quotient 9 as the next digit in the result. 
Result so far: 32755.69
Deduct 7803 from 8580 and we're left with 777.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7770, and continue the process.

Going ahead to step 11:
867 can be fit into 7770 8 times, resulting in a remainder of 834.
Record the quotient 8 as the next digit in the result. 
Result so far: 32755.698
Deduct 6936 from 7770 and we're left with 834.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8340, and continue the process.

On to step 12:
8340 divided by 867 is 9 with a remainder of 537.
Put 9 as the next digit of the answer. 
Result so far: 32755.6989
If we subtract 7803 from 8340, we get 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

On to step 13:
When dividing 5370 by 867, we get 6 with a remainder of 168.
The next digit of our result is 6. 
Result so far: 32755.69896
Subtracting 5202 from 5370 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 14:
The number 867 fits into 1680 1 times, leaving a remainder of 813.
Record the quotient 1 as the next digit in the result. 
Result so far: 32755.698961
Subtracting 867 from 1680 leaves us with 813.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8130, and continue the process.

Step 15:
When dividing 8130 by 867, we get 9 with a remainder of 327.
The next digit of our result is 9. 
Result so far: 32755.6989619
If we subtract 7803 from 8130, we get 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

On to step 16:
The number 867 fits into 3270 3 times, leaving a remainder of 669.
Write down 3 as next digit of the result. 
Result so far: 32755.69896193
Subtract 2601 from 3270 to get 669.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6690, and continue the process.

After the division, we end up with 32755.69896193 and a remainder of 6.69e-07.
