Let's divide 40123833 by 780
The aim is to understand the frequency of 780 in 40123833.

On to step 1:
The number 780 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 780

Going ahead to step 2:
40 divided by 780 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Grab the next digit (1) from the dividend, add it to 40, then carry on: 401 / 780

Going ahead to step 3:
The number 780 fits into 401 0 times, leaving a remainder of 401.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 401 and we're left with 401.
Include the next digit (2) from the dividend after 401, then repeat: 4012 / 780

On to step 4:
If we divide 4012 by 780, we get 5 and a remainder of 112.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 3900 from 4012, we get 112.
Fetch the next digit (3) from the dividend, attach it to 112 and continue: 1123 / 780

Advancing to step 5:
1123 divided by 780 is 1 with a remainder of 343.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
The remainder is 343 after subtracting 780 from 1123.
Grab the next digit (8) from the dividend, add it to 343, then carry on: 3438 / 780

On to step 6:
If we divide 3438 by 780, we get 4 and a remainder of 318.
Write down 4 as next digit of the result. 
Result so far: 514.0
Deduct 3120 from 3438 and we're left with 318.
Take the next digit (3) from the dividend and append it to 318, then repeat: 3183 / 780

Let's proceed to step 7:
780 can be fit into 3183 4 times, resulting in a remainder of 63.
Record the quotient 4 as the next digit in the result. 
Result so far: 5144.0
Deduct 3120 from 3183 and we're left with 63.
Take the next digit (3) from the dividend and append it to 63, then repeat: 633 / 780

Going ahead to step 8:
The number 780 fits into 633 0 times, leaving a remainder of 633.
The number 0 becomes the next digit in our result. 
Result so far: 51440.0
Deduct 0 from 633 and we're left with 633.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6330, and continue the process.

Let's proceed to step 9:
When dividing 6330 by 780, we get 8 with a remainder of 90.
Record the quotient 8 as the next digit in the result. 
Result so far: 51440.8
If we subtract 6240 from 6330, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 10:
780 goes into 900 1 times with a remainder of 120.
Put 1 as the next digit of the answer. 
Result so far: 51440.81
Subtract 780 from 900 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 11:
780 goes into 1200 1 times with a remainder of 420.
Record the quotient 1 as the next digit in the result. 
Result so far: 51440.811
Subtract 780 from 1200 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

After the division, we end up with 51440.811 and a remainder of 0.042.
