833601 divided by 40 
The aim is to understand the frequency of 40 in 833601.

Going ahead to step 1:
8 divided by 40 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 40

On to step 2:
40 can be fit into 83 2 times, resulting in a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 80 from 83, we get 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 40

On to step 3:
If we divide 33 by 40, we get 0 and a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Deduct 0 from 33 and we're left with 33.
Grab the next digit (6) from the dividend, add it to 33, then carry on: 336 / 40

Moving on to step 4:
The number 40 fits into 336 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 208.0
The remainder is 16 after subtracting 320 from 336.
Append the next digit (0) from the dividend to 16 and continue with: 160 / 40

Let's proceed to step 5:
40 can be fit into 160 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 2084.0
If we take 160 away from 160, we end up with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 40

On to step 6:
40 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 20840.0
The remainder is 1 after subtracting 0 from 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
40 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 20840.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
40 can be fit into 100 2 times, resulting in a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 20840.02
Subtract 80 from 100 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.

Going ahead to step 9:
40 can be fit into 200 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 20840.025
If we take 200 away from 200, 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.

Going ahead 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: 20840.025
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.

Let's proceed to step 11:
40 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 20840.025
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 quotient of the division is 20840.025, and the remainder is 0.0.
