Let's divide 18120084 by 317
The aim is to understand the frequency of 317 in 18120084.

On to step 1:
317 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 317

Moving on to step 2:
If we divide 18 by 317, we get 0 and a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 317

Going ahead to step 3:
The number 317 fits into 181 0 times, leaving a remainder of 181.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 181, we get 181.
Take the next digit (2) from the dividend and append it to 181, then repeat: 1812 / 317

Going ahead to step 4:
317 goes into 1812 5 times with a remainder of 227.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 1585 from 1812 to get 227.
Grab the next digit (0) from the dividend, add it to 227, then carry on: 2270 / 317

Let's proceed to step 5:
2270 divided by 317 is 7 with a remainder of 51.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
The remainder is 51 after subtracting 2219 from 2270.
Grab the next digit (0) from the dividend, add it to 51, then carry on: 510 / 317

Advancing to step 6:
When dividing 510 by 317, we get 1 with a remainder of 193.
The next digit of our result is 1. 
Result so far: 571.0
Subtract 317 from 510 to get 193.
Take the next digit (8) from the dividend and append it to 193, then repeat: 1938 / 317

Let's proceed to step 7:
If we divide 1938 by 317, we get 6 and a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 5716.0
Subtract 1902 from 1938 to get 36.
Fetch the next digit (4) from the dividend, attach it to 36 and continue: 364 / 317

Going ahead to step 8:
When dividing 364 by 317, we get 1 with a remainder of 47.
Use 1 as the next digit of our solution. 
Result so far: 57161.0
Deduct 317 from 364 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 9:
317 can be fit into 470 1 times, resulting in a remainder of 153.
Use 1 as the next digit of our solution. 
Result so far: 57161.1
The remainder is 153 after subtracting 317 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Advancing to step 10:
1530 divided by 317 is 4 with a remainder of 262.
Record the quotient 4 as the next digit in the result. 
Result so far: 57161.14
The remainder is 262 after subtracting 1268 from 1530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

On to step 11:
When dividing 2620 by 317, we get 8 with a remainder of 84.
Write down 8 as next digit of the result. 
Result so far: 57161.148
If we subtract 2536 from 2620, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 12:
The number 317 fits into 840 2 times, leaving a remainder of 206.
Write down 2 as next digit of the result. 
Result so far: 57161.1482
If we take 634 away from 840, we end up with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Let's proceed to step 13:
317 goes into 2060 6 times with a remainder of 158.
Put 6 as the next digit of the answer. 
Result so far: 57161.14826
Subtracting 1902 from 2060 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Let's proceed to step 14:
1580 divided by 317 is 4 with a remainder of 312.
The next digit of our result is 4. 
Result so far: 57161.148264
Subtract 1268 from 1580 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Advancing to step 15:
317 can be fit into 3120 9 times, resulting in a remainder of 267.
The number 9 becomes the next digit in our result. 
Result so far: 57161.1482649
Deduct 2853 from 3120 and we're left with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Let's proceed to step 16:
2670 divided by 317 is 8 with a remainder of 134.
Write down 8 as next digit of the result. 
Result so far: 57161.14826498
If we take 2536 away from 2670, we end up with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

The final outcome is 57161.14826498, with a leftover of 1.34e-07.
