We look at the division of 151211 by 316 
The aim is to understand the frequency of 316 in 151211.

Let's proceed to step 1:
If we divide 1 by 316, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 316

On to step 2:
When dividing 15 by 316, we get 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 316

Going ahead to step 3:
316 can be fit into 151 0 times, resulting in a remainder of 151.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 151 after subtracting 0 from 151.
Take the next digit (2) from the dividend and append it to 151, then repeat: 1512 / 316

Moving on to step 4:
1512 divided by 316 is 4 with a remainder of 248.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 1264 away from 1512, we end up with 248.
Include the next digit (1) from the dividend after 248, then repeat: 2481 / 316

Going ahead to step 5:
When dividing 2481 by 316, we get 7 with a remainder of 269.
Write down 7 as next digit of the result. 
Result so far: 47.0
Deduct 2212 from 2481 and we're left with 269.
Take the next digit (1) from the dividend and append it to 269, then repeat: 2691 / 316

Let's proceed to step 6:
If we divide 2691 by 316, we get 8 and a remainder of 163.
Write down 8 as next digit of the result. 
Result so far: 478.0
Subtract 2528 from 2691 to get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Let's proceed to step 7:
1630 divided by 316 is 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 478.5
If we take 1580 away from 1630, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
If we divide 500 by 316, we get 1 and a remainder of 184.
Use 1 as the next digit of our solution. 
Result so far: 478.51
The remainder is 184 after subtracting 316 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 9:
316 can be fit into 1840 5 times, resulting in a remainder of 260.
Record the quotient 5 as the next digit in the result. 
Result so far: 478.515
If we take 1580 away from 1840, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 10:
The number 316 fits into 2600 8 times, leaving a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 478.5158
Subtracting 2528 from 2600 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 11:
When dividing 720 by 316, we get 2 with a remainder of 88.
Record the quotient 2 as the next digit in the result. 
Result so far: 478.51582
If we subtract 632 from 720, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 12:
316 goes into 880 2 times with a remainder of 248.
The number 2 becomes the next digit in our result. 
Result so far: 478.515822
Deduct 632 from 880 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

After the division, we end up with 478.515822 and a remainder of 2.48e-05.
