We look at the division of 40987669 by 599 
The aim is to understand the frequency of 599 in 40987669.

On to step 1:
4 divided by 599 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 599

Step 2:
If we divide 40 by 599, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Fetch the next digit (9) from the dividend, attach it to 40 and continue: 409 / 599

Moving on to step 3:
When dividing 409 by 599, we get 0 with a remainder of 409.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 409, we end up with 409.
Bring next digit (8) of the dividend behind the 409 and repeat the process: 4098 / 599

Let's proceed to step 4:
599 can be fit into 4098 6 times, resulting in a remainder of 504.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 3594 from 4098 leaves us with 504.
Append the next digit (7) from the dividend to 504 and continue with: 5047 / 599

Advancing to step 5:
599 goes into 5047 8 times with a remainder of 255.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
Deduct 4792 from 5047 and we're left with 255.
Include the next digit (6) from the dividend after 255, then repeat: 2556 / 599

Advancing to step 6:
2556 divided by 599 is 4 with a remainder of 160.
The next digit of our result is 4. 
Result so far: 684.0
Deduct 2396 from 2556 and we're left with 160.
Include the next digit (6) from the dividend after 160, then repeat: 1606 / 599

Step 7:
1606 divided by 599 is 2 with a remainder of 408.
Write down 2 as next digit of the result. 
Result so far: 6842.0
If we subtract 1198 from 1606, we get 408.
Include the next digit (9) from the dividend after 408, then repeat: 4089 / 599

Let's proceed to step 8:
The number 599 fits into 4089 6 times, leaving a remainder of 495.
The next digit of our result is 6. 
Result so far: 68426.0
Subtract 3594 from 4089 to get 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

On to step 9:
4950 divided by 599 is 8 with a remainder of 158.
Write down 8 as next digit of the result. 
Result so far: 68426.8
If we subtract 4792 from 4950, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Step 10:
1580 divided by 599 is 2 with a remainder of 382.
The number 2 becomes the next digit in our result. 
Result so far: 68426.82
If we take 1198 away from 1580, we end up with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

On to step 11:
If we divide 3820 by 599, we get 6 and a remainder of 226.
Put 6 as the next digit of the answer. 
Result so far: 68426.826
Deduct 3594 from 3820 and we're left with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Going ahead to step 12:
The number 599 fits into 2260 3 times, leaving a remainder of 463.
Record the quotient 3 as the next digit in the result. 
Result so far: 68426.8263
If we subtract 1797 from 2260, we get 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

On to step 13:
When dividing 4630 by 599, we get 7 with a remainder of 437.
Put 7 as the next digit of the answer. 
Result so far: 68426.82637
The remainder is 437 after subtracting 4193 from 4630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Advancing to step 14:
The number 599 fits into 4370 7 times, leaving a remainder of 177.
Use 7 as the next digit of our solution. 
Result so far: 68426.826377
Subtract 4193 from 4370 to get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

In conclusion, the division gives 68426.826377 with a balance of 1.77e-05.
