85780290 ÷ 867 
The aim is to understand the frequency of 867 in 85780290.

Let's proceed to step 1:
If we divide 8 by 867, 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 (5) from the dividend and append it to 8, then repeat: 85 / 867

Moving on to step 2:
867 goes into 85 0 times with a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Grab the next digit (7) from the dividend, add it to 85, then carry on: 857 / 867

Moving on to step 3:
When dividing 857 by 867, we get 0 with a remainder of 857.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 857 leaves us with 857.
Append the next digit (8) from the dividend to 857 and continue with: 8578 / 867

On to step 4:
If we divide 8578 by 867, we get 9 and a remainder of 775.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 7803 away from 8578, we end up with 775.
Append the next digit (0) from the dividend to 775 and continue with: 7750 / 867

Advancing to step 5:
867 goes into 7750 8 times with a remainder of 814.
Use 8 as the next digit of our solution. 
Result so far: 98.0
If we take 6936 away from 7750, we end up with 814.
Grab the next digit (2) from the dividend, add it to 814, then carry on: 8142 / 867

Moving on to step 6:
867 goes into 8142 9 times with a remainder of 339.
Record the quotient 9 as the next digit in the result. 
Result so far: 989.0
If we take 7803 away from 8142, we end up with 339.
Include the next digit (9) from the dividend after 339, then repeat: 3399 / 867

Going ahead to step 7:
If we divide 3399 by 867, we get 3 and a remainder of 798.
Write down 3 as next digit of the result. 
Result so far: 9893.0
Deduct 2601 from 3399 and we're left with 798.
Bring next digit (0) of the dividend behind the 798 and repeat the process: 7980 / 867

Advancing to step 8:
When dividing 7980 by 867, we get 9 with a remainder of 177.
The number 9 becomes the next digit in our result. 
Result so far: 98939.0
If we subtract 7803 from 7980, we get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Going ahead to step 9:
If we divide 1770 by 867, we get 2 and a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 98939.2
Deduct 1734 from 1770 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 10:
360 divided by 867 is 0 with a remainder of 360.
The next digit of our result is 0. 
Result so far: 98939.2
Deduct 0 from 360 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 11:
3600 divided by 867 is 4 with a remainder of 132.
Use 4 as the next digit of our solution. 
Result so far: 98939.204
If we subtract 3468 from 3600, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 12:
867 goes into 1320 1 times with a remainder of 453.
Put 1 as the next digit of the answer. 
Result so far: 98939.2041
Subtracting 867 from 1320 leaves us with 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Moving on to step 13:
If we divide 4530 by 867, we get 5 and a remainder of 195.
The number 5 becomes the next digit in our result. 
Result so far: 98939.20415
The remainder is 195 after subtracting 4335 from 4530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Moving on to step 14:
When dividing 1950 by 867, we get 2 with a remainder of 216.
Use 2 as the next digit of our solution. 
Result so far: 98939.204152
Deduct 1734 from 1950 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Going ahead to step 15:
The number 867 fits into 2160 2 times, leaving a remainder of 426.
Put 2 as the next digit of the answer. 
Result so far: 98939.2041522
Deduct 1734 from 2160 and we're left with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

In conclusion, the division gives 98939.2041522 with a balance of 4.26e-06.
