We're dividing 8894188 by 391 
The aim is to understand the frequency of 391 in 8894188.

Advancing to step 1:
391 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 391

On to step 2:
391 goes into 88 0 times with a remainder of 88.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 88 after subtracting 0 from 88.
Include the next digit (9) from the dividend after 88, then repeat: 889 / 391

On to step 3:
The number 391 fits into 889 2 times, leaving a remainder of 107.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 782 from 889 leaves us with 107.
Bring next digit (4) of the dividend behind the 107 and repeat the process: 1074 / 391

Going ahead to step 4:
391 goes into 1074 2 times with a remainder of 292.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we subtract 782 from 1074, we get 292.
Take the next digit (1) from the dividend and append it to 292, then repeat: 2921 / 391

Step 5:
The number 391 fits into 2921 7 times, leaving a remainder of 184.
Use 7 as the next digit of our solution. 
Result so far: 227.0
If we take 2737 away from 2921, we end up with 184.
Bring next digit (8) of the dividend behind the 184 and repeat the process: 1848 / 391

Step 6:
When dividing 1848 by 391, we get 4 with a remainder of 284.
Use 4 as the next digit of our solution. 
Result so far: 2274.0
If we take 1564 away from 1848, we end up with 284.
Take the next digit (8) from the dividend and append it to 284, then repeat: 2848 / 391

Let's proceed to step 7:
If we divide 2848 by 391, we get 7 and a remainder of 111.
The number 7 becomes the next digit in our result. 
Result so far: 22747.0
Deduct 2737 from 2848 and we're left with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Moving on to step 8:
When dividing 1110 by 391, we get 2 with a remainder of 328.
Record the quotient 2 as the next digit in the result. 
Result so far: 22747.2
The remainder is 328 after subtracting 782 from 1110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Let's proceed to step 9:
3280 divided by 391 is 8 with a remainder of 152.
The next digit of our result is 8. 
Result so far: 22747.28
The remainder is 152 after subtracting 3128 from 3280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 10:
1520 divided by 391 is 3 with a remainder of 347.
Write down 3 as next digit of the result. 
Result so far: 22747.283
Deduct 1173 from 1520 and we're left with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

On to step 11:
If we divide 3470 by 391, we get 8 and a remainder of 342.
Record the quotient 8 as the next digit in the result. 
Result so far: 22747.2838
If we take 3128 away from 3470, we end up with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Moving on to step 12:
391 goes into 3420 8 times with a remainder of 292.
Write down 8 as next digit of the result. 
Result so far: 22747.28388
Subtract 3128 from 3420 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

After the division, we end up with 22747.28388 and a remainder of 0.000292.
