We divide 71668853 by 307
The aim is to understand the frequency of 307 in 71668853.

Let's proceed to step 1:
When dividing 7 by 307, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 307

Let's proceed to step 2:
307 goes into 71 0 times with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Grab the next digit (6) from the dividend, add it to 71, then carry on: 716 / 307

Moving on to step 3:
The number 307 fits into 716 2 times, leaving a remainder of 102.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 614 from 716, we get 102.
Append the next digit (6) from the dividend to 102 and continue with: 1026 / 307

Moving on to step 4:
If we divide 1026 by 307, we get 3 and a remainder of 105.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtracting 921 from 1026 leaves us with 105.
Include the next digit (8) from the dividend after 105, then repeat: 1058 / 307

Let's proceed to step 5:
307 goes into 1058 3 times with a remainder of 137.
Use 3 as the next digit of our solution. 
Result so far: 233.0
If we subtract 921 from 1058, we get 137.
Include the next digit (8) from the dividend after 137, then repeat: 1378 / 307

Step 6:
1378 divided by 307 is 4 with a remainder of 150.
Record the quotient 4 as the next digit in the result. 
Result so far: 2334.0
If we take 1228 away from 1378, we end up with 150.
Append the next digit (5) from the dividend to 150 and continue with: 1505 / 307

On to step 7:
The number 307 fits into 1505 4 times, leaving a remainder of 277.
Put 4 as the next digit of the answer. 
Result so far: 23344.0
If we subtract 1228 from 1505, we get 277.
Append the next digit (3) from the dividend to 277 and continue with: 2773 / 307

Going ahead to step 8:
When dividing 2773 by 307, we get 9 with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 233449.0
Deduct 2763 from 2773 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
The number 307 fits into 100 0 times, leaving a remainder of 100.
The next digit of our result is 0. 
Result so far: 233449.0
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 10:
If we divide 1000 by 307, we get 3 and a remainder of 79.
Use 3 as the next digit of our solution. 
Result so far: 233449.03
Subtract 921 from 1000 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 11:
The number 307 fits into 790 2 times, leaving a remainder of 176.
Put 2 as the next digit of the answer. 
Result so far: 233449.032
Deduct 614 from 790 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 12:
1760 divided by 307 is 5 with a remainder of 225.
Use 5 as the next digit of our solution. 
Result so far: 233449.0325
Subtracting 1535 from 1760 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Let's proceed to step 13:
When dividing 2250 by 307, we get 7 with a remainder of 101.
The next digit of our result is 7. 
Result so far: 233449.03257
Subtracting 2149 from 2250 leaves us with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Moving on to step 14:
307 can be fit into 1010 3 times, resulting in a remainder of 89.
Use 3 as the next digit of our solution. 
Result so far: 233449.032573
Subtract 921 from 1010 to get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Advancing to step 15:
When dividing 890 by 307, we get 2 with a remainder of 276.
Record the quotient 2 as the next digit in the result. 
Result so far: 233449.0325732
Subtract 614 from 890 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Advancing to step 16:
If we divide 2760 by 307, we get 8 and a remainder of 304.
The next digit of our result is 8. 
Result so far: 233449.03257328
If we take 2456 away from 2760, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

The quotient of the division is 233449.03257328, and the remainder is 3.04e-07.
