We divide 689863 by 40
The aim is to understand the frequency of 40 in 689863.

Step 1:
40 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 40

Step 2:
40 goes into 68 1 times with a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 40 from 68 leaves us with 28.
Take the next digit (9) from the dividend and append it to 28, then repeat: 289 / 40

Step 3:
The number 40 fits into 289 7 times, leaving a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
The remainder is 9 after subtracting 280 from 289.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 40

Let's proceed to step 4:
40 goes into 98 2 times with a remainder of 18.
The next digit of our result is 2. 
Result so far: 172.0
The remainder is 18 after subtracting 80 from 98.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 40

On to step 5:
186 divided by 40 is 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 1724.0
Subtract 160 from 186 to get 26.
Append the next digit (3) from the dividend to 26 and continue with: 263 / 40

Let's proceed to step 6:
40 goes into 263 6 times with a remainder of 23.
Record the quotient 6 as the next digit in the result. 
Result so far: 17246.0
Subtracting 240 from 263 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 7:
The number 40 fits into 230 5 times, leaving a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 17246.5
Subtract 200 from 230 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
40 goes into 300 7 times with a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 17246.57
Subtract 280 from 300 to 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.

Step 9:
40 can be fit into 200 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 17246.575
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.

Moving on to step 10:
40 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 17246.575
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.

On to step 11:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 17246.575
If we take 0 away from 0, we end up 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 17246.575 with a remainder of 0.0.
