We divide 76797018 by 810
The aim is to understand the frequency of 810 in 76797018.

On to step 1:
The number 810 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 810

Moving on to step 2:
The number 810 fits into 76 0 times, leaving a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 76 and we're left with 76.
Take the next digit (7) from the dividend and append it to 76, then repeat: 767 / 810

Going ahead to step 3:
767 divided by 810 is 0 with a remainder of 767.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 767 and we're left with 767.
Fetch the next digit (9) from the dividend, attach it to 767 and continue: 7679 / 810

Step 4:
810 goes into 7679 9 times with a remainder of 389.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 389 after subtracting 7290 from 7679.
Grab the next digit (7) from the dividend, add it to 389, then carry on: 3897 / 810

On to step 5:
The number 810 fits into 3897 4 times, leaving a remainder of 657.
Use 4 as the next digit of our solution. 
Result so far: 94.0
If we take 3240 away from 3897, we end up with 657.
Append the next digit (0) from the dividend to 657 and continue with: 6570 / 810

On to step 6:
6570 divided by 810 is 8 with a remainder of 90.
The next digit of our result is 8. 
Result so far: 948.0
If we subtract 6480 from 6570, we get 90.
Grab the next digit (1) from the dividend, add it to 90, then carry on: 901 / 810

Moving on to step 7:
If we divide 901 by 810, we get 1 and a remainder of 91.
Put 1 as the next digit of the answer. 
Result so far: 9481.0
Subtract 810 from 901 to get 91.
Take the next digit (8) from the dividend and append it to 91, then repeat: 918 / 810

Moving on to step 8:
810 goes into 918 1 times with a remainder of 108.
The number 1 becomes the next digit in our result. 
Result so far: 94811.0
The remainder is 108 after subtracting 810 from 918.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 9:
810 goes into 1080 1 times with a remainder of 270.
Record the quotient 1 as the next digit in the result. 
Result so far: 94811.1
If we take 810 away from 1080, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 10:
The number 810 fits into 2700 3 times, leaving a remainder of 270.
Record the quotient 3 as the next digit in the result. 
Result so far: 94811.13
If we take 2430 away from 2700, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 11:
The number 810 fits into 2700 3 times, leaving a remainder of 270.
Write down 3 as next digit of the result. 
Result so far: 94811.133
Subtracting 2430 from 2700 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

The final result is 94811.133 with a remainder of 0.027.
