Let's divide 84186399 by 331
The aim is to understand the frequency of 331 in 84186399.

Let's proceed to step 1:
331 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 331

Step 2:
331 goes into 84 0 times with a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Include the next digit (1) from the dividend after 84, then repeat: 841 / 331

Advancing to step 3:
If we divide 841 by 331, we get 2 and a remainder of 179.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 662 from 841 leaves us with 179.
Bring next digit (8) of the dividend behind the 179 and repeat the process: 1798 / 331

Let's proceed to step 4:
When dividing 1798 by 331, we get 5 with a remainder of 143.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Deduct 1655 from 1798 and we're left with 143.
Grab the next digit (6) from the dividend, add it to 143, then carry on: 1436 / 331

Advancing to step 5:
If we divide 1436 by 331, we get 4 and a remainder of 112.
Record the quotient 4 as the next digit in the result. 
Result so far: 254.0
If we take 1324 away from 1436, we end up with 112.
Take the next digit (3) from the dividend and append it to 112, then repeat: 1123 / 331

Let's proceed to step 6:
1123 divided by 331 is 3 with a remainder of 130.
Write down 3 as next digit of the result. 
Result so far: 2543.0
Subtracting 993 from 1123 leaves us with 130.
Bring next digit (9) of the dividend behind the 130 and repeat the process: 1309 / 331

On to step 7:
The number 331 fits into 1309 3 times, leaving a remainder of 316.
Write down 3 as next digit of the result. 
Result so far: 25433.0
Subtract 993 from 1309 to get 316.
Bring next digit (9) of the dividend behind the 316 and repeat the process: 3169 / 331

Step 8:
3169 divided by 331 is 9 with a remainder of 190.
The number 9 becomes the next digit in our result. 
Result so far: 254339.0
Deduct 2979 from 3169 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 9:
331 goes into 1900 5 times with a remainder of 245.
Use 5 as the next digit of our solution. 
Result so far: 254339.5
Deduct 1655 from 1900 and we're left with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Going ahead to step 10:
2450 divided by 331 is 7 with a remainder of 133.
Record the quotient 7 as the next digit in the result. 
Result so far: 254339.57
If we take 2317 away from 2450, we end up with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Going ahead to step 11:
1330 divided by 331 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 254339.574
Subtract 1324 from 1330 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
331 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 254339.574
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 13:
If we divide 600 by 331, we get 1 and a remainder of 269.
Use 1 as the next digit of our solution. 
Result so far: 254339.57401
Subtracting 331 from 600 leaves us with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Moving on to step 14:
If we divide 2690 by 331, we get 8 and a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 254339.574018
Deduct 2648 from 2690 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 15:
420 divided by 331 is 1 with a remainder of 89.
The number 1 becomes the next digit in our result. 
Result so far: 254339.5740181
The remainder is 89 after subtracting 331 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Let's proceed to step 16:
If we divide 890 by 331, we get 2 and a remainder of 228.
Use 2 as the next digit of our solution. 
Result so far: 254339.57401812
If we take 662 away from 890, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

The final result is 254339.57401812 with a remainder of 2.28e-07.
