8536901 divided by 40 
The aim is to understand the frequency of 40 in 8536901.

Step 1:
40 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 40

Moving on to step 2:
If we divide 85 by 40, we get 2 and a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 5 after subtracting 80 from 85.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 40

Step 3:
40 can be fit into 53 1 times, resulting in a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
The remainder is 13 after subtracting 40 from 53.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 40

Advancing to step 4:
When dividing 136 by 40, we get 3 with a remainder of 16.
The next digit of our result is 3. 
Result so far: 213.0
If we subtract 120 from 136, we get 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 40

Going ahead to step 5:
When dividing 169 by 40, we get 4 with a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 2134.0
The remainder is 9 after subtracting 160 from 169.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 40

Advancing to step 6:
40 goes into 90 2 times with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 21342.0
If we take 80 away from 90, we end up with 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 40

Step 7:
The number 40 fits into 101 2 times, leaving a remainder of 21.
The next digit of our result is 2. 
Result so far: 213422.0
Deduct 80 from 101 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 8:
The number 40 fits into 210 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 213422.5
Subtracting 200 from 210 leaves us 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 9:
100 divided by 40 is 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 213422.52
The remainder is 20 after subtracting 80 from 100.
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 10:
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: 213422.525
The remainder is 0 after subtracting 200 from 200.
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:
If we divide 0 by 40, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 213422.525
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.

On to step 12:
40 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 213422.525
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.

In conclusion, the division gives 213422.525 with a balance of 0.0.
