697124 divided by 40 
The aim is to understand the frequency of 40 in 697124.

Step 1:
40 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 40

Moving on to step 2:
If we divide 69 by 40, we get 1 and a remainder of 29.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 40 from 69 and we're left with 29.
Grab the next digit (7) from the dividend, add it to 29, then carry on: 297 / 40

Going ahead to step 3:
The number 40 fits into 297 7 times, leaving a remainder of 17.
The next digit of our result is 7. 
Result so far: 17.0
Subtracting 280 from 297 leaves us with 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 40

Let's proceed to step 4:
40 can be fit into 171 4 times, resulting in a remainder of 11.
The next digit of our result is 4. 
Result so far: 174.0
Deduct 160 from 171 and we're left with 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 40

Step 5:
The number 40 fits into 112 2 times, leaving a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 1742.0
The remainder is 32 after subtracting 80 from 112.
Fetch the next digit (4) from the dividend, attach it to 32 and continue: 324 / 40

Let's proceed to step 6:
40 can be fit into 324 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 17428.0
Subtracting 320 from 324 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
When dividing 40 by 40, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 17428.1
The remainder is 0 after subtracting 40 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
When dividing 0 by 40, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 17428.1
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.

Advancing to step 9:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 17428.1
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.

The final result is 17428.1 with a remainder of 0.0.
