We look at the division of 31396808 by 151 
The aim is to understand the frequency of 151 in 31396808.

Going ahead to step 1:
When dividing 3 by 151, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 151

On to step 2:
151 goes into 31 0 times with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Take the next digit (3) from the dividend and append it to 31, then repeat: 313 / 151

On to step 3:
151 goes into 313 2 times with a remainder of 11.
The next digit of our result is 2. 
Result so far: 2.0
If we take 302 away from 313, we end up with 11.
Grab the next digit (9) from the dividend, add it to 11, then carry on: 119 / 151

Moving on to step 4:
119 divided by 151 is 0 with a remainder of 119.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we take 0 away from 119, we end up with 119.
Grab the next digit (6) from the dividend, add it to 119, then carry on: 1196 / 151

On to step 5:
151 goes into 1196 7 times with a remainder of 139.
Put 7 as the next digit of the answer. 
Result so far: 207.0
The remainder is 139 after subtracting 1057 from 1196.
Fetch the next digit (8) from the dividend, attach it to 139 and continue: 1398 / 151

Let's proceed to step 6:
The number 151 fits into 1398 9 times, leaving a remainder of 39.
The next digit of our result is 9. 
Result so far: 2079.0
The remainder is 39 after subtracting 1359 from 1398.
Fetch the next digit (0) from the dividend, attach it to 39 and continue: 390 / 151

Step 7:
151 goes into 390 2 times with a remainder of 88.
The next digit of our result is 2. 
Result so far: 20792.0
Deduct 302 from 390 and we're left with 88.
Append the next digit (8) from the dividend to 88 and continue with: 888 / 151

On to step 8:
151 can be fit into 888 5 times, resulting in a remainder of 133.
Put 5 as the next digit of the answer. 
Result so far: 207925.0
The remainder is 133 after subtracting 755 from 888.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Advancing to step 9:
151 goes into 1330 8 times with a remainder of 122.
Use 8 as the next digit of our solution. 
Result so far: 207925.8
Subtracting 1208 from 1330 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 10:
151 can be fit into 1220 8 times, resulting in a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 207925.88
If we subtract 1208 from 1220, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 207925.88 with a balance of 0.012.
