We divide 80402211 by 807
The aim is to understand the frequency of 807 in 80402211.

On to step 1:
807 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 807

Let's proceed to step 2:
80 divided by 807 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Fetch the next digit (4) from the dividend, attach it to 80 and continue: 804 / 807

Moving on to step 3:
804 divided by 807 is 0 with a remainder of 804.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 804 leaves us with 804.
Grab the next digit (0) from the dividend, add it to 804, then carry on: 8040 / 807

On to step 4:
807 can be fit into 8040 9 times, resulting in a remainder of 777.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 7263 away from 8040, we end up with 777.
Fetch the next digit (2) from the dividend, attach it to 777 and continue: 7772 / 807

Going ahead to step 5:
The number 807 fits into 7772 9 times, leaving a remainder of 509.
The next digit of our result is 9. 
Result so far: 99.0
The remainder is 509 after subtracting 7263 from 7772.
Fetch the next digit (2) from the dividend, attach it to 509 and continue: 5092 / 807

Moving on to step 6:
If we divide 5092 by 807, we get 6 and a remainder of 250.
Record the quotient 6 as the next digit in the result. 
Result so far: 996.0
Deduct 4842 from 5092 and we're left with 250.
Fetch the next digit (1) from the dividend, attach it to 250 and continue: 2501 / 807

Let's proceed to step 7:
807 goes into 2501 3 times with a remainder of 80.
Use 3 as the next digit of our solution. 
Result so far: 9963.0
Subtract 2421 from 2501 to get 80.
Include the next digit (1) from the dividend after 80, then repeat: 801 / 807

Let's proceed to step 8:
When dividing 801 by 807, we get 0 with a remainder of 801.
Record the quotient 0 as the next digit in the result. 
Result so far: 99630.0
If we subtract 0 from 801, we get 801.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8010, and continue the process.

Going ahead to step 9:
807 can be fit into 8010 9 times, resulting in a remainder of 747.
Write down 9 as next digit of the result. 
Result so far: 99630.9
If we take 7263 away from 8010, we end up with 747.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7470, and continue the process.

Moving on to step 10:
The number 807 fits into 7470 9 times, leaving a remainder of 207.
Put 9 as the next digit of the answer. 
Result so far: 99630.99
If we take 7263 away from 7470, we end up with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

The final outcome is 99630.99, with a leftover of 0.207.
