We look at the division of 6666000 by 783 
The aim is to understand the frequency of 783 in 6666000.

Moving on to step 1:
783 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 783

Advancing to step 2:
783 goes into 66 0 times with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Grab the next digit (6) from the dividend, add it to 66, then carry on: 666 / 783

Moving on to step 3:
783 goes into 666 0 times with a remainder of 666.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 666, we end up with 666.
Fetch the next digit (6) from the dividend, attach it to 666 and continue: 6666 / 783

Going ahead to step 4:
If we divide 6666 by 783, we get 8 and a remainder of 402.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 6264 from 6666 and we're left with 402.
Take the next digit (0) from the dividend and append it to 402, then repeat: 4020 / 783

Going ahead to step 5:
4020 divided by 783 is 5 with a remainder of 105.
Put 5 as the next digit of the answer. 
Result so far: 85.0
The remainder is 105 after subtracting 3915 from 4020.
Take the next digit (0) from the dividend and append it to 105, then repeat: 1050 / 783

Step 6:
The number 783 fits into 1050 1 times, leaving a remainder of 267.
The number 1 becomes the next digit in our result. 
Result so far: 851.0
Subtract 783 from 1050 to get 267.
Include the next digit (0) from the dividend after 267, then repeat: 2670 / 783

Advancing to step 7:
783 can be fit into 2670 3 times, resulting in a remainder of 321.
The next digit of our result is 3. 
Result so far: 8513.0
If we take 2349 away from 2670, we end up with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Advancing to step 8:
When dividing 3210 by 783, we get 4 with a remainder of 78.
Use 4 as the next digit of our solution. 
Result so far: 8513.4
If we take 3132 away from 3210, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 9:
The number 783 fits into 780 0 times, leaving a remainder of 780.
Write down 0 as next digit of the result. 
Result so far: 8513.4
If we subtract 0 from 780, we get 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Moving on to step 10:
The number 783 fits into 7800 9 times, leaving a remainder of 753.
Record the quotient 9 as the next digit in the result. 
Result so far: 8513.409
Subtracting 7047 from 7800 leaves us with 753.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7530, and continue the process.

Step 11:
783 goes into 7530 9 times with a remainder of 483.
The next digit of our result is 9. 
Result so far: 8513.4099
If we take 7047 away from 7530, we end up with 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

After the division, we end up with 8513.4099 and a remainder of 0.00483.
