99250547 ÷ 659 
The aim is to understand the frequency of 659 in 99250547.

Going ahead to step 1:
When dividing 9 by 659, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 659

Going ahead to step 2:
If we divide 99 by 659, we get 0 and a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Fetch the next digit (2) from the dividend, attach it to 99 and continue: 992 / 659

Step 3:
The number 659 fits into 992 1 times, leaving a remainder of 333.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 659 from 992 to get 333.
Take the next digit (5) from the dividend and append it to 333, then repeat: 3335 / 659

Moving on to step 4:
3335 divided by 659 is 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 3295 away from 3335, we end up with 40.
Append the next digit (0) from the dividend to 40 and continue with: 400 / 659

Moving on to step 5:
400 divided by 659 is 0 with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 150.0
The remainder is 400 after subtracting 0 from 400.
Fetch the next digit (5) from the dividend, attach it to 400 and continue: 4005 / 659

Advancing to step 6:
659 can be fit into 4005 6 times, resulting in a remainder of 51.
The next digit of our result is 6. 
Result so far: 1506.0
Subtracting 3954 from 4005 leaves us with 51.
Include the next digit (4) from the dividend after 51, then repeat: 514 / 659

Advancing to step 7:
514 divided by 659 is 0 with a remainder of 514.
Put 0 as the next digit of the answer. 
Result so far: 15060.0
The remainder is 514 after subtracting 0 from 514.
Fetch the next digit (7) from the dividend, attach it to 514 and continue: 5147 / 659

Moving on to step 8:
If we divide 5147 by 659, we get 7 and a remainder of 534.
Write down 7 as next digit of the result. 
Result so far: 150607.0
If we subtract 4613 from 5147, we get 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Step 9:
The number 659 fits into 5340 8 times, leaving a remainder of 68.
Use 8 as the next digit of our solution. 
Result so far: 150607.8
The remainder is 68 after subtracting 5272 from 5340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 10:
680 divided by 659 is 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 150607.81
The remainder is 21 after subtracting 659 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 11:
The number 659 fits into 210 0 times, leaving a remainder of 210.
Record the quotient 0 as the next digit in the result. 
Result so far: 150607.81
If we subtract 0 from 210, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 12:
The number 659 fits into 2100 3 times, leaving a remainder of 123.
Record the quotient 3 as the next digit in the result. 
Result so far: 150607.8103
Deduct 1977 from 2100 and we're left with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Step 13:
The number 659 fits into 1230 1 times, leaving a remainder of 571.
The number 1 becomes the next digit in our result. 
Result so far: 150607.81031
If we subtract 659 from 1230, we get 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Step 14:
5710 divided by 659 is 8 with a remainder of 438.
The number 8 becomes the next digit in our result. 
Result so far: 150607.810318
If we subtract 5272 from 5710, we get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Going ahead to step 15:
The number 659 fits into 4380 6 times, leaving a remainder of 426.
Write down 6 as next digit of the result. 
Result so far: 150607.8103186
If we take 3954 away from 4380, we end up with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Moving on to step 16:
659 can be fit into 4260 6 times, resulting in a remainder of 306.
Put 6 as the next digit of the answer. 
Result so far: 150607.81031866
Deduct 3954 from 4260 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

In conclusion, the division gives 150607.81031866 with a balance of 3.06e-07.
