80949689 ÷ 599 
The aim is to understand the frequency of 599 in 80949689.

Going ahead to step 1:
599 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 599

On to step 2:
599 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Bring next digit (9) of the dividend behind the 80 and repeat the process: 809 / 599

Advancing to step 3:
When dividing 809 by 599, we get 1 with a remainder of 210.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 210 after subtracting 599 from 809.
Append the next digit (4) from the dividend to 210 and continue with: 2104 / 599

Moving on to step 4:
599 goes into 2104 3 times with a remainder of 307.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 1797 from 2104 to get 307.
Grab the next digit (9) from the dividend, add it to 307, then carry on: 3079 / 599

Let's proceed to step 5:
When dividing 3079 by 599, we get 5 with a remainder of 84.
The next digit of our result is 5. 
Result so far: 135.0
Subtract 2995 from 3079 to get 84.
Fetch the next digit (6) from the dividend, attach it to 84 and continue: 846 / 599

Step 6:
599 goes into 846 1 times with a remainder of 247.
The next digit of our result is 1. 
Result so far: 1351.0
Subtract 599 from 846 to get 247.
Fetch the next digit (8) from the dividend, attach it to 247 and continue: 2478 / 599

On to step 7:
599 goes into 2478 4 times with a remainder of 82.
The next digit of our result is 4. 
Result so far: 13514.0
If we subtract 2396 from 2478, we get 82.
Append the next digit (9) from the dividend to 82 and continue with: 829 / 599

On to step 8:
829 divided by 599 is 1 with a remainder of 230.
Use 1 as the next digit of our solution. 
Result so far: 135141.0
If we subtract 599 from 829, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 9:
When dividing 2300 by 599, we get 3 with a remainder of 503.
Write down 3 as next digit of the result. 
Result so far: 135141.3
Subtract 1797 from 2300 to get 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Going ahead to step 10:
599 goes into 5030 8 times with a remainder of 238.
The next digit of our result is 8. 
Result so far: 135141.38
Deduct 4792 from 5030 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Moving on to step 11:
599 can be fit into 2380 3 times, resulting in a remainder of 583.
Write down 3 as next digit of the result. 
Result so far: 135141.383
Subtract 1797 from 2380 to get 583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

Going ahead to step 12:
If we divide 5830 by 599, we get 9 and a remainder of 439.
Record the quotient 9 as the next digit in the result. 
Result so far: 135141.3839
If we subtract 5391 from 5830, we get 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Step 13:
If we divide 4390 by 599, we get 7 and a remainder of 197.
The next digit of our result is 7. 
Result so far: 135141.38397
Deduct 4193 from 4390 and we're left with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Going ahead to step 14:
When dividing 1970 by 599, we get 3 with a remainder of 173.
The number 3 becomes the next digit in our result. 
Result so far: 135141.383973
Deduct 1797 from 1970 and we're left with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Moving on to step 15:
1730 divided by 599 is 2 with a remainder of 532.
The number 2 becomes the next digit in our result. 
Result so far: 135141.3839732
Subtract 1198 from 1730 to get 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Let's proceed to step 16:
5320 divided by 599 is 8 with a remainder of 528.
Put 8 as the next digit of the answer. 
Result so far: 135141.38397328
Subtract 4792 from 5320 to get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

The final result is 135141.38397328 with a remainder of 5.28e-07.
