We divide 3001094 by 391
The aim is to understand the frequency of 391 in 3001094.

Going ahead to step 1:
3 divided by 391 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 391

Going ahead to step 2:
The number 391 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 391

On to step 3:
If we divide 300 by 391, we get 0 and a remainder of 300.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 300, we end up with 300.
Fetch the next digit (1) from the dividend, attach it to 300 and continue: 3001 / 391

On to step 4:
391 can be fit into 3001 7 times, resulting in a remainder of 264.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 2737 from 3001 and we're left with 264.
Bring next digit (0) of the dividend behind the 264 and repeat the process: 2640 / 391

On to step 5:
When dividing 2640 by 391, we get 6 with a remainder of 294.
The next digit of our result is 6. 
Result so far: 76.0
Subtracting 2346 from 2640 leaves us with 294.
Append the next digit (9) from the dividend to 294 and continue with: 2949 / 391

On to step 6:
391 goes into 2949 7 times with a remainder of 212.
Use 7 as the next digit of our solution. 
Result so far: 767.0
Subtract 2737 from 2949 to get 212.
Include the next digit (4) from the dividend after 212, then repeat: 2124 / 391

Let's proceed to step 7:
If we divide 2124 by 391, we get 5 and a remainder of 169.
Put 5 as the next digit of the answer. 
Result so far: 7675.0
Subtract 1955 from 2124 to get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Going ahead to step 8:
1690 divided by 391 is 4 with a remainder of 126.
Write down 4 as next digit of the result. 
Result so far: 7675.4
If we take 1564 away from 1690, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 9:
If we divide 1260 by 391, we get 3 and a remainder of 87.
Use 3 as the next digit of our solution. 
Result so far: 7675.43
If we subtract 1173 from 1260, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 10:
391 can be fit into 870 2 times, resulting in a remainder of 88.
Record the quotient 2 as the next digit in the result. 
Result so far: 7675.432
Deduct 782 from 870 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 11:
The number 391 fits into 880 2 times, leaving a remainder of 98.
Use 2 as the next digit of our solution. 
Result so far: 7675.4322
The remainder is 98 after subtracting 782 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

The quotient of the division is 7675.4322, and the remainder is 0.00098.
