40135519 ÷ 608 
The aim is to understand the frequency of 608 in 40135519.

Step 1:
4 divided by 608 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 608

Step 2:
The number 608 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Fetch the next digit (1) from the dividend, attach it to 40 and continue: 401 / 608

Advancing to step 3:
The number 608 fits into 401 0 times, leaving a remainder of 401.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 401 and we're left with 401.
Fetch the next digit (3) from the dividend, attach it to 401 and continue: 4013 / 608

On to step 4:
608 goes into 4013 6 times with a remainder of 365.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 3648 from 4013 leaves us with 365.
Take the next digit (5) from the dividend and append it to 365, then repeat: 3655 / 608

Advancing to step 5:
3655 divided by 608 is 6 with a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 66.0
Subtracting 3648 from 3655 leaves us with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 608

On to step 6:
If we divide 75 by 608, we get 0 and a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 660.0
Subtract 0 from 75 to get 75.
Append the next digit (1) from the dividend to 75 and continue with: 751 / 608

Let's proceed to step 7:
The number 608 fits into 751 1 times, leaving a remainder of 143.
Write down 1 as next digit of the result. 
Result so far: 6601.0
If we subtract 608 from 751, we get 143.
Fetch the next digit (9) from the dividend, attach it to 143 and continue: 1439 / 608

Step 8:
When dividing 1439 by 608, we get 2 with a remainder of 223.
The number 2 becomes the next digit in our result. 
Result so far: 66012.0
Deduct 1216 from 1439 and we're left with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

On to step 9:
When dividing 2230 by 608, we get 3 with a remainder of 406.
Use 3 as the next digit of our solution. 
Result so far: 66012.3
Subtracting 1824 from 2230 leaves us with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Going ahead to step 10:
The number 608 fits into 4060 6 times, leaving a remainder of 412.
Record the quotient 6 as the next digit in the result. 
Result so far: 66012.36
Subtract 3648 from 4060 to get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Moving on to step 11:
The number 608 fits into 4120 6 times, leaving a remainder of 472.
Put 6 as the next digit of the answer. 
Result so far: 66012.366
Deduct 3648 from 4120 and we're left with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

The quotient of the division is 66012.366, and the remainder is 0.0472.
