We look at the division of 48552451 by 307 
The aim is to understand the frequency of 307 in 48552451.

On to step 1:
When dividing 4 by 307, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 307

Advancing to step 2:
48 divided by 307 is 0 with a remainder of 48.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 48, we end up with 48.
Grab the next digit (5) from the dividend, add it to 48, then carry on: 485 / 307

Going ahead to step 3:
485 divided by 307 is 1 with a remainder of 178.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 307 from 485, we get 178.
Include the next digit (5) from the dividend after 178, then repeat: 1785 / 307

Going ahead to step 4:
The number 307 fits into 1785 5 times, leaving a remainder of 250.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 1535 from 1785 and we're left with 250.
Take the next digit (2) from the dividend and append it to 250, then repeat: 2502 / 307

Going ahead to step 5:
When dividing 2502 by 307, we get 8 with a remainder of 46.
The number 8 becomes the next digit in our result. 
Result so far: 158.0
If we take 2456 away from 2502, we end up with 46.
Append the next digit (4) from the dividend to 46 and continue with: 464 / 307

Advancing to step 6:
If we divide 464 by 307, we get 1 and a remainder of 157.
The next digit of our result is 1. 
Result so far: 1581.0
Deduct 307 from 464 and we're left with 157.
Grab the next digit (5) from the dividend, add it to 157, then carry on: 1575 / 307

Let's proceed to step 7:
307 goes into 1575 5 times with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 15815.0
Subtract 1535 from 1575 to get 40.
Grab the next digit (1) from the dividend, add it to 40, then carry on: 401 / 307

Advancing to step 8:
307 can be fit into 401 1 times, resulting in a remainder of 94.
The number 1 becomes the next digit in our result. 
Result so far: 158151.0
If we take 307 away from 401, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 9:
When dividing 940 by 307, we get 3 with a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 158151.3
Subtract 921 from 940 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 10:
The number 307 fits into 190 0 times, leaving a remainder of 190.
The number 0 becomes the next digit in our result. 
Result so far: 158151.3
Subtracting 0 from 190 leaves us 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.

Let's proceed to step 11:
307 goes into 1900 6 times with a remainder of 58.
Write down 6 as next digit of the result. 
Result so far: 158151.306
If we subtract 1842 from 1900, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 12:
307 can be fit into 580 1 times, resulting in a remainder of 273.
Record the quotient 1 as the next digit in the result. 
Result so far: 158151.3061
If we take 307 away from 580, we end up with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

On to step 13:
307 can be fit into 2730 8 times, resulting in a remainder of 274.
Use 8 as the next digit of our solution. 
Result so far: 158151.30618
Subtracting 2456 from 2730 leaves us with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Step 14:
307 can be fit into 2740 8 times, resulting in a remainder of 284.
Write down 8 as next digit of the result. 
Result so far: 158151.306188
If we take 2456 away from 2740, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Our division results in 158151.306188 with a remaining 2.84e-05.
