429923 ÷ 40 
The aim is to understand the frequency of 40 in 429923.

Moving on to step 1:
The number 40 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
Subtracting 0 from 4 leaves us with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 40

Advancing to step 2:
If we divide 42 by 40, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 40 from 42 to get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 40

Advancing to step 3:
29 divided by 40 is 0 with a remainder of 29.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 29, we end up with 29.
Grab the next digit (9) from the dividend, add it to 29, then carry on: 299 / 40

Advancing to step 4:
The number 40 fits into 299 7 times, leaving a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 107.0
The remainder is 19 after subtracting 280 from 299.
Grab the next digit (2) from the dividend, add it to 19, then carry on: 192 / 40

Step 5:
192 divided by 40 is 4 with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 1074.0
Deduct 160 from 192 and we're left with 32.
Bring next digit (3) of the dividend behind the 32 and repeat the process: 323 / 40

Going ahead to step 6:
If we divide 323 by 40, we get 8 and a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 10748.0
Deduct 320 from 323 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
When dividing 30 by 40, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 10748.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
40 can be fit into 300 7 times, resulting in a remainder of 20.
The next digit of our result is 7. 
Result so far: 10748.07
If we take 280 away from 300, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
40 can be fit into 200 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 10748.075
Deduct 200 from 200 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.

Moving on to step 10:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10748.075
Subtracting 0 from 0 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.

Going ahead to step 11:
0 divided by 40 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10748.075
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.

The quotient of the division is 10748.075, and the remainder is 0.0.
