We look at the division of 86694649 by 151 
The aim is to understand the frequency of 151 in 86694649.

Moving on to step 1:
When dividing 8 by 151, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 151

Advancing to step 2:
86 divided by 151 is 0 with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Include the next digit (6) from the dividend after 86, then repeat: 866 / 151

On to step 3:
The number 151 fits into 866 5 times, leaving a remainder of 111.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 755 from 866, we get 111.
Fetch the next digit (9) from the dividend, attach it to 111 and continue: 1119 / 151

Going ahead to step 4:
151 goes into 1119 7 times with a remainder of 62.
Put 7 as the next digit of the answer. 
Result so far: 57.0
Deduct 1057 from 1119 and we're left with 62.
Include the next digit (4) from the dividend after 62, then repeat: 624 / 151

Moving on to step 5:
When dividing 624 by 151, we get 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 574.0
Deduct 604 from 624 and we're left with 20.
Grab the next digit (6) from the dividend, add it to 20, then carry on: 206 / 151

Let's proceed to step 6:
151 goes into 206 1 times with a remainder of 55.
Record the quotient 1 as the next digit in the result. 
Result so far: 5741.0
Subtract 151 from 206 to get 55.
Bring next digit (4) of the dividend behind the 55 and repeat the process: 554 / 151

Going ahead to step 7:
If we divide 554 by 151, we get 3 and a remainder of 101.
Put 3 as the next digit of the answer. 
Result so far: 57413.0
If we subtract 453 from 554, we get 101.
Grab the next digit (9) from the dividend, add it to 101, then carry on: 1019 / 151

Moving on to step 8:
The number 151 fits into 1019 6 times, leaving a remainder of 113.
Use 6 as the next digit of our solution. 
Result so far: 574136.0
If we take 906 away from 1019, we end up with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Moving on to step 9:
151 goes into 1130 7 times with a remainder of 73.
Write down 7 as next digit of the result. 
Result so far: 574136.7
The remainder is 73 after subtracting 1057 from 1130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 10:
151 can be fit into 730 4 times, resulting in a remainder of 126.
The number 4 becomes the next digit in our result. 
Result so far: 574136.74
If we take 604 away from 730, we end up 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.

Let's proceed to step 11:
If we divide 1260 by 151, we get 8 and a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 574136.748
The remainder is 52 after subtracting 1208 from 1260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 12:
520 divided by 151 is 3 with a remainder of 67.
The next digit of our result is 3. 
Result so far: 574136.7483
If we take 453 away from 520, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 13:
When dividing 670 by 151, we get 4 with a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 574136.74834
Subtract 604 from 670 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 14:
When dividing 660 by 151, we get 4 with a remainder of 56.
The next digit of our result is 4. 
Result so far: 574136.748344
The remainder is 56 after subtracting 604 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

After the division, we end up with 574136.748344 and a remainder of 5.6e-06.
