We look at the division of 762829 by 40 
The aim is to understand the frequency of 40 in 762829.

Advancing to step 1:
The number 40 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 40

Going ahead to step 2:
When dividing 76 by 40, we get 1 with a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 40 from 76 to get 36.
Take the next digit (2) from the dividend and append it to 36, then repeat: 362 / 40

Advancing to step 3:
If we divide 362 by 40, we get 9 and a remainder of 2.
The next digit of our result is 9. 
Result so far: 19.0
The remainder is 2 after subtracting 360 from 362.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 40

Moving on to step 4:
If we divide 28 by 40, we get 0 and a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 190.0
If we take 0 away from 28, we end up with 28.
Fetch the next digit (2) from the dividend, attach it to 28 and continue: 282 / 40

Let's proceed to step 5:
40 goes into 282 7 times with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 1907.0
If we subtract 280 from 282, we get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 40

Advancing to step 6:
When dividing 29 by 40, we get 0 with a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 19070.0
If we subtract 0 from 29, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 7:
The number 40 fits into 290 7 times, leaving a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 19070.7
If we subtract 280 from 290, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
100 divided by 40 is 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 19070.72
If we subtract 80 from 100, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
The number 40 fits into 200 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 19070.725
Subtracting 200 from 200 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
0 divided by 40 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 19070.725
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
0 divided by 40 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 19070.725
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 19070.725 and a remainder of 0.0.
