We divide 72818473 by 807
The aim is to understand the frequency of 807 in 72818473.

On to step 1:
The number 807 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 807

Advancing to step 2:
72 divided by 807 is 0 with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Take the next digit (8) from the dividend and append it to 72, then repeat: 728 / 807

Step 3:
728 divided by 807 is 0 with a remainder of 728.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 728 after subtracting 0 from 728.
Append the next digit (1) from the dividend to 728 and continue with: 7281 / 807

Going ahead to step 4:
If we divide 7281 by 807, we get 9 and a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 7263 from 7281 leaves us with 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 807

Going ahead to step 5:
188 divided by 807 is 0 with a remainder of 188.
Write down 0 as next digit of the result. 
Result so far: 90.0
If we subtract 0 from 188, we get 188.
Take the next digit (4) from the dividend and append it to 188, then repeat: 1884 / 807

On to step 6:
If we divide 1884 by 807, we get 2 and a remainder of 270.
The next digit of our result is 2. 
Result so far: 902.0
Deduct 1614 from 1884 and we're left with 270.
Grab the next digit (7) from the dividend, add it to 270, then carry on: 2707 / 807

Going ahead to step 7:
807 goes into 2707 3 times with a remainder of 286.
Use 3 as the next digit of our solution. 
Result so far: 9023.0
Subtracting 2421 from 2707 leaves us with 286.
Bring next digit (3) of the dividend behind the 286 and repeat the process: 2863 / 807

Going ahead to step 8:
807 goes into 2863 3 times with a remainder of 442.
Put 3 as the next digit of the answer. 
Result so far: 90233.0
Subtracting 2421 from 2863 leaves us with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

Step 9:
807 goes into 4420 5 times with a remainder of 385.
The next digit of our result is 5. 
Result so far: 90233.5
The remainder is 385 after subtracting 4035 from 4420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Advancing to step 10:
If we divide 3850 by 807, we get 4 and a remainder of 622.
Put 4 as the next digit of the answer. 
Result so far: 90233.54
If we subtract 3228 from 3850, we get 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Going ahead to step 11:
807 can be fit into 6220 7 times, resulting in a remainder of 571.
Write down 7 as next digit of the result. 
Result so far: 90233.547
If we subtract 5649 from 6220, we get 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Step 12:
If we divide 5710 by 807, we get 7 and a remainder of 61.
Record the quotient 7 as the next digit in the result. 
Result so far: 90233.5477
The remainder is 61 after subtracting 5649 from 5710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

The final result is 90233.5477 with a remainder of 0.00061.
