We're dividing 19860309 by 914 
The aim is to understand the frequency of 914 in 19860309.

On to step 1:
914 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 914

Advancing to step 2:
The number 914 fits into 19 0 times, leaving a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 914

Moving on to step 3:
The number 914 fits into 198 0 times, leaving a remainder of 198.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 198, we get 198.
Bring next digit (6) of the dividend behind the 198 and repeat the process: 1986 / 914

Moving on to step 4:
914 can be fit into 1986 2 times, resulting in a remainder of 158.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 1828 from 1986, we get 158.
Fetch the next digit (0) from the dividend, attach it to 158 and continue: 1580 / 914

On to step 5:
914 can be fit into 1580 1 times, resulting in a remainder of 666.
Write down 1 as next digit of the result. 
Result so far: 21.0
The remainder is 666 after subtracting 914 from 1580.
Grab the next digit (3) from the dividend, add it to 666, then carry on: 6663 / 914

Moving on to step 6:
If we divide 6663 by 914, we get 7 and a remainder of 265.
Record the quotient 7 as the next digit in the result. 
Result so far: 217.0
If we subtract 6398 from 6663, we get 265.
Append the next digit (0) from the dividend to 265 and continue with: 2650 / 914

Step 7:
914 can be fit into 2650 2 times, resulting in a remainder of 822.
Use 2 as the next digit of our solution. 
Result so far: 2172.0
The remainder is 822 after subtracting 1828 from 2650.
Include the next digit (9) from the dividend after 822, then repeat: 8229 / 914

Advancing to step 8:
8229 divided by 914 is 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 21729.0
Subtracting 8226 from 8229 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
30 divided by 914 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 21729.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
The number 914 fits into 300 0 times, leaving a remainder of 300.
The next digit of our result is 0. 
Result so far: 21729.0
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final outcome is 21729.0, with a leftover of 0.3.
