We divide 462681 by 309
The aim is to understand the frequency of 309 in 462681.

Advancing to step 1:
When dividing 4 by 309, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 309

Going ahead to step 2:
The number 309 fits into 46 0 times, leaving a remainder of 46.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 46, we get 46.
Fetch the next digit (2) from the dividend, attach it to 46 and continue: 462 / 309

On to step 3:
309 can be fit into 462 1 times, resulting in a remainder of 153.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 309 from 462 leaves us with 153.
Take the next digit (6) from the dividend and append it to 153, then repeat: 1536 / 309

On to step 4:
309 can be fit into 1536 4 times, resulting in a remainder of 300.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 1236 from 1536 leaves us with 300.
Grab the next digit (8) from the dividend, add it to 300, then carry on: 3008 / 309

Going ahead to step 5:
309 goes into 3008 9 times with a remainder of 227.
Put 9 as the next digit of the answer. 
Result so far: 149.0
Deduct 2781 from 3008 and we're left with 227.
Take the next digit (1) from the dividend and append it to 227, then repeat: 2271 / 309

Going ahead to step 6:
309 can be fit into 2271 7 times, resulting in a remainder of 108.
Record the quotient 7 as the next digit in the result. 
Result so far: 1497.0
Subtract 2163 from 2271 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 7:
309 can be fit into 1080 3 times, resulting in a remainder of 153.
The next digit of our result is 3. 
Result so far: 1497.3
If we subtract 927 from 1080, we get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

On to step 8:
When dividing 1530 by 309, we get 4 with a remainder of 294.
Record the quotient 4 as the next digit in the result. 
Result so far: 1497.34
Deduct 1236 from 1530 and we're left with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Going ahead to step 9:
When dividing 2940 by 309, we get 9 with a remainder of 159.
Record the quotient 9 as the next digit in the result. 
Result so far: 1497.349
Subtracting 2781 from 2940 leaves us with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Advancing to step 10:
309 goes into 1590 5 times with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 1497.3495
Subtracting 1545 from 1590 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 11:
309 can be fit into 450 1 times, resulting in a remainder of 141.
Put 1 as the next digit of the answer. 
Result so far: 1497.34951
The remainder is 141 after subtracting 309 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Step 12:
When dividing 1410 by 309, we get 4 with a remainder of 174.
Put 4 as the next digit of the answer. 
Result so far: 1497.349514
Deduct 1236 from 1410 and we're left 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.

Advancing to step 13:
When dividing 1740 by 309, we get 5 with a remainder of 195.
Write down 5 as next digit of the result. 
Result so far: 1497.3495145
The remainder is 195 after subtracting 1545 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Going ahead to step 14:
309 goes into 1950 6 times with a remainder of 96.
Use 6 as the next digit of our solution. 
Result so far: 1497.34951456
The remainder is 96 after subtracting 1854 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

The final outcome is 1497.34951456, with a leftover of 9.6e-08.
