Let's divide 70395363 by 807
The aim is to understand the frequency of 807 in 70395363.

Step 1:
When dividing 7 by 807, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 807

Going ahead to step 2:
The number 807 fits into 70 0 times, leaving a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Take the next digit (3) from the dividend and append it to 70, then repeat: 703 / 807

Going ahead to step 3:
807 can be fit into 703 0 times, resulting in a remainder of 703.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 703, we get 703.
Fetch the next digit (9) from the dividend, attach it to 703 and continue: 7039 / 807

Moving on to step 4:
If we divide 7039 by 807, we get 8 and a remainder of 583.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 6456 from 7039 leaves us with 583.
Grab the next digit (5) from the dividend, add it to 583, then carry on: 5835 / 807

Moving on to step 5:
The number 807 fits into 5835 7 times, leaving a remainder of 186.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
If we subtract 5649 from 5835, we get 186.
Fetch the next digit (3) from the dividend, attach it to 186 and continue: 1863 / 807

Step 6:
The number 807 fits into 1863 2 times, leaving a remainder of 249.
The number 2 becomes the next digit in our result. 
Result so far: 872.0
Subtract 1614 from 1863 to get 249.
Grab the next digit (6) from the dividend, add it to 249, then carry on: 2496 / 807

Advancing to step 7:
When dividing 2496 by 807, we get 3 with a remainder of 75.
Put 3 as the next digit of the answer. 
Result so far: 8723.0
Subtract 2421 from 2496 to get 75.
Include the next digit (3) from the dividend after 75, then repeat: 753 / 807

Going ahead to step 8:
If we divide 753 by 807, we get 0 and a remainder of 753.
The next digit of our result is 0. 
Result so far: 87230.0
Deduct 0 from 753 and we're left 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.

Moving on to step 9:
When dividing 7530 by 807, we get 9 with a remainder of 267.
Write down 9 as next digit of the result. 
Result so far: 87230.9
Deduct 7263 from 7530 and we're left with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

On to step 10:
When dividing 2670 by 807, we get 3 with a remainder of 249.
Record the quotient 3 as the next digit in the result. 
Result so far: 87230.93
If we take 2421 away from 2670, we end up with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Advancing to step 11:
807 goes into 2490 3 times with a remainder of 69.
Use 3 as the next digit of our solution. 
Result so far: 87230.933
Subtract 2421 from 2490 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

The quotient of the division is 87230.933, and the remainder is 0.0069.
