We divide 28164283 by 391
The aim is to understand the frequency of 391 in 28164283.

Let's proceed to step 1:
When dividing 2 by 391, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 391

Advancing to step 2:
391 can be fit into 28 0 times, resulting in a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Take the next digit (1) from the dividend and append it to 28, then repeat: 281 / 391

Step 3:
The number 391 fits into 281 0 times, leaving a remainder of 281.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 281 after subtracting 0 from 281.
Grab the next digit (6) from the dividend, add it to 281, then carry on: 2816 / 391

Step 4:
2816 divided by 391 is 7 with a remainder of 79.
The next digit of our result is 7. 
Result so far: 7.0
If we take 2737 away from 2816, we end up with 79.
Append the next digit (4) from the dividend to 79 and continue with: 794 / 391

Step 5:
391 can be fit into 794 2 times, resulting in a remainder of 12.
The next digit of our result is 2. 
Result so far: 72.0
Subtract 782 from 794 to get 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 391

Let's proceed to step 6:
The number 391 fits into 122 0 times, leaving a remainder of 122.
The number 0 becomes the next digit in our result. 
Result so far: 720.0
If we subtract 0 from 122, we get 122.
Grab the next digit (8) from the dividend, add it to 122, then carry on: 1228 / 391

Moving on to step 7:
391 goes into 1228 3 times with a remainder of 55.
Put 3 as the next digit of the answer. 
Result so far: 7203.0
Subtract 1173 from 1228 to get 55.
Append the next digit (3) from the dividend to 55 and continue with: 553 / 391

On to step 8:
391 can be fit into 553 1 times, resulting in a remainder of 162.
Put 1 as the next digit of the answer. 
Result so far: 72031.0
The remainder is 162 after subtracting 391 from 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Moving on to step 9:
The number 391 fits into 1620 4 times, leaving a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 72031.4
The remainder is 56 after subtracting 1564 from 1620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 10:
The number 391 fits into 560 1 times, leaving a remainder of 169.
Write down 1 as next digit of the result. 
Result so far: 72031.41
If we take 391 away from 560, we end up with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Let's proceed to step 11:
391 goes into 1690 4 times with a remainder of 126.
Write down 4 as next digit of the result. 
Result so far: 72031.414
Deduct 1564 from 1690 and we're left 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.

On to step 12:
If we divide 1260 by 391, we get 3 and a remainder of 87.
Write down 3 as next digit of the result. 
Result so far: 72031.4143
Subtract 1173 from 1260 to 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.

Going ahead to step 13:
870 divided by 391 is 2 with a remainder of 88.
Put 2 as the next digit of the answer. 
Result so far: 72031.41432
The remainder is 88 after subtracting 782 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 14:
If we divide 880 by 391, we get 2 and a remainder of 98.
The next digit of our result is 2. 
Result so far: 72031.414322
Deduct 782 from 880 and we're left with 98.
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 72031.414322, and the remainder is 9.8e-06.
