Let's divide 8678632 by 391
The aim is to understand the frequency of 391 in 8678632.

Moving on to step 1:
If we divide 8 by 391, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 391

Moving on to step 2:
391 goes into 86 0 times with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Include the next digit (7) from the dividend after 86, then repeat: 867 / 391

Let's proceed to step 3:
867 divided by 391 is 2 with a remainder of 85.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 782 from 867 leaves us with 85.
Fetch the next digit (8) from the dividend, attach it to 85 and continue: 858 / 391

Moving on to step 4:
391 can be fit into 858 2 times, resulting in a remainder of 76.
Write down 2 as next digit of the result. 
Result so far: 22.0
The remainder is 76 after subtracting 782 from 858.
Grab the next digit (6) from the dividend, add it to 76, then carry on: 766 / 391

Going ahead to step 5:
766 divided by 391 is 1 with a remainder of 375.
Use 1 as the next digit of our solution. 
Result so far: 221.0
If we subtract 391 from 766, we get 375.
Append the next digit (3) from the dividend to 375 and continue with: 3753 / 391

Advancing to step 6:
If we divide 3753 by 391, we get 9 and a remainder of 234.
The next digit of our result is 9. 
Result so far: 2219.0
Deduct 3519 from 3753 and we're left with 234.
Fetch the next digit (2) from the dividend, attach it to 234 and continue: 2342 / 391

Advancing to step 7:
2342 divided by 391 is 5 with a remainder of 387.
Record the quotient 5 as the next digit in the result. 
Result so far: 22195.0
The remainder is 387 after subtracting 1955 from 2342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Let's proceed to step 8:
The number 391 fits into 3870 9 times, leaving a remainder of 351.
The next digit of our result is 9. 
Result so far: 22195.9
If we subtract 3519 from 3870, we get 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Let's proceed to step 9:
When dividing 3510 by 391, we get 8 with a remainder of 382.
Put 8 as the next digit of the answer. 
Result so far: 22195.98
If we take 3128 away from 3510, we end up 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.

Let's proceed to step 10:
391 can be fit into 3820 9 times, resulting in a remainder of 301.
The next digit of our result is 9. 
Result so far: 22195.989
The remainder is 301 after subtracting 3519 from 3820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

On to step 11:
391 can be fit into 3010 7 times, resulting in a remainder of 273.
The number 7 becomes the next digit in our result. 
Result so far: 22195.9897
If we take 2737 away from 3010, we end up with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Step 12:
2730 divided by 391 is 6 with a remainder of 384.
Write down 6 as next digit of the result. 
Result so far: 22195.98976
If we subtract 2346 from 2730, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 13:
The number 391 fits into 3840 9 times, leaving a remainder of 321.
Record the quotient 9 as the next digit in the result. 
Result so far: 22195.989769
Subtract 3519 from 3840 to get 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Going ahead to step 14:
391 goes into 3210 8 times with a remainder of 82.
The next digit of our result is 8. 
Result so far: 22195.9897698
The remainder is 82 after subtracting 3128 from 3210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 15:
820 divided by 391 is 2 with a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 22195.98976982
If we subtract 782 from 820, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Our division results in 22195.98976982 with a remaining 3.8e-08.
