We divide 71872666 by 307
The aim is to understand the frequency of 307 in 71872666.

Advancing to step 1:
When dividing 7 by 307, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 307

Moving on to step 2:
307 can be fit into 71 0 times, resulting in a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Bring next digit (8) of the dividend behind the 71 and repeat the process: 718 / 307

Let's proceed to step 3:
307 goes into 718 2 times with a remainder of 104.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 614 from 718 leaves us with 104.
Include the next digit (7) from the dividend after 104, then repeat: 1047 / 307

Going ahead to step 4:
If we divide 1047 by 307, we get 3 and a remainder of 126.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtract 921 from 1047 to get 126.
Take the next digit (2) from the dividend and append it to 126, then repeat: 1262 / 307

Step 5:
307 goes into 1262 4 times with a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 234.0
Subtracting 1228 from 1262 leaves us with 34.
Grab the next digit (6) from the dividend, add it to 34, then carry on: 346 / 307

Let's proceed to step 6:
307 goes into 346 1 times with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 2341.0
Deduct 307 from 346 and we're left with 39.
Include the next digit (6) from the dividend after 39, then repeat: 396 / 307

Going ahead to step 7:
307 goes into 396 1 times with a remainder of 89.
Put 1 as the next digit of the answer. 
Result so far: 23411.0
Deduct 307 from 396 and we're left with 89.
Fetch the next digit (6) from the dividend, attach it to 89 and continue: 896 / 307

Step 8:
The number 307 fits into 896 2 times, leaving a remainder of 282.
Put 2 as the next digit of the answer. 
Result so far: 234112.0
The remainder is 282 after subtracting 614 from 896.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 9:
307 goes into 2820 9 times with a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 234112.9
Subtracting 2763 from 2820 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 10:
307 can be fit into 570 1 times, resulting in a remainder of 263.
Write down 1 as next digit of the result. 
Result so far: 234112.91
The remainder is 263 after subtracting 307 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Advancing to step 11:
If we divide 2630 by 307, we get 8 and a remainder of 174.
Write down 8 as next digit of the result. 
Result so far: 234112.918
Subtracting 2456 from 2630 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Step 12:
When dividing 1740 by 307, we get 5 with a remainder of 205.
Put 5 as the next digit of the answer. 
Result so far: 234112.9185
Subtract 1535 from 1740 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Step 13:
When dividing 2050 by 307, we get 6 with a remainder of 208.
Use 6 as the next digit of our solution. 
Result so far: 234112.91856
Deduct 1842 from 2050 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 14:
307 can be fit into 2080 6 times, resulting in a remainder of 238.
Write down 6 as next digit of the result. 
Result so far: 234112.918566
Deduct 1842 from 2080 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

After the division, we end up with 234112.918566 and a remainder of 2.38e-05.
