Let's divide 79778520 by 405
The aim is to understand the frequency of 405 in 79778520.

Moving on to step 1:
405 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 405

Advancing to step 2:
When dividing 79 by 405, we get 0 with a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 79, we end up with 79.
Grab the next digit (7) from the dividend, add it to 79, then carry on: 797 / 405

Going ahead to step 3:
When dividing 797 by 405, we get 1 with a remainder of 392.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 405 from 797 leaves us with 392.
Fetch the next digit (7) from the dividend, attach it to 392 and continue: 3927 / 405

Advancing to step 4:
3927 divided by 405 is 9 with a remainder of 282.
Use 9 as the next digit of our solution. 
Result so far: 19.0
The remainder is 282 after subtracting 3645 from 3927.
Fetch the next digit (8) from the dividend, attach it to 282 and continue: 2828 / 405

On to step 5:
2828 divided by 405 is 6 with a remainder of 398.
Use 6 as the next digit of our solution. 
Result so far: 196.0
Subtract 2430 from 2828 to get 398.
Grab the next digit (5) from the dividend, add it to 398, then carry on: 3985 / 405

Going ahead to step 6:
The number 405 fits into 3985 9 times, leaving a remainder of 340.
Record the quotient 9 as the next digit in the result. 
Result so far: 1969.0
If we take 3645 away from 3985, we end up with 340.
Append the next digit (2) from the dividend to 340 and continue with: 3402 / 405

Advancing to step 7:
3402 divided by 405 is 8 with a remainder of 162.
The number 8 becomes the next digit in our result. 
Result so far: 19698.0
If we subtract 3240 from 3402, we get 162.
Bring next digit (0) of the dividend behind the 162 and repeat the process: 1620 / 405

Going ahead to step 8:
1620 divided by 405 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 196984.0
If we subtract 1620 from 1620, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
When dividing 0 by 405, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 196984.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
405 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 196984.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 196984.0 and a remainder of 0.0.
