We're dividing 99011999 by 107 
The aim is to understand the frequency of 107 in 99011999.

Step 1:
The number 107 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 107

Step 2:
The number 107 fits into 99 0 times, leaving a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Grab the next digit (0) from the dividend, add it to 99, then carry on: 990 / 107

Let's proceed to step 3:
The number 107 fits into 990 9 times, leaving a remainder of 27.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 963 from 990 leaves us with 27.
Append the next digit (1) from the dividend to 27 and continue with: 271 / 107

Let's proceed to step 4:
107 can be fit into 271 2 times, resulting in a remainder of 57.
Use 2 as the next digit of our solution. 
Result so far: 92.0
The remainder is 57 after subtracting 214 from 271.
Bring next digit (1) of the dividend behind the 57 and repeat the process: 571 / 107

Let's proceed to step 5:
107 goes into 571 5 times with a remainder of 36.
The next digit of our result is 5. 
Result so far: 925.0
Deduct 535 from 571 and we're left with 36.
Include the next digit (9) from the dividend after 36, then repeat: 369 / 107

On to step 6:
369 divided by 107 is 3 with a remainder of 48.
The number 3 becomes the next digit in our result. 
Result so far: 9253.0
The remainder is 48 after subtracting 321 from 369.
Grab the next digit (9) from the dividend, add it to 48, then carry on: 489 / 107

Step 7:
If we divide 489 by 107, we get 4 and a remainder of 61.
The number 4 becomes the next digit in our result. 
Result so far: 92534.0
Subtract 428 from 489 to get 61.
Take the next digit (9) from the dividend and append it to 61, then repeat: 619 / 107

Moving on to step 8:
If we divide 619 by 107, we get 5 and a remainder of 84.
Record the quotient 5 as the next digit in the result. 
Result so far: 925345.0
Subtract 535 from 619 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 9:
When dividing 840 by 107, we get 7 with a remainder of 91.
The number 7 becomes the next digit in our result. 
Result so far: 925345.7
If we take 749 away from 840, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Going ahead to step 10:
If we divide 910 by 107, we get 8 and a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 925345.78
Subtracting 856 from 910 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 11:
If we divide 540 by 107, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 925345.785
If we take 535 away from 540, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 12:
50 divided by 107 is 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 925345.785
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 13:
500 divided by 107 is 4 with a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 925345.78504
Deduct 428 from 500 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 14:
107 goes into 720 6 times with a remainder of 78.
Record the quotient 6 as the next digit in the result. 
Result so far: 925345.785046
The remainder is 78 after subtracting 642 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 15:
107 can be fit into 780 7 times, resulting in a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 925345.7850467
Subtract 749 from 780 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 16:
When dividing 310 by 107, we get 2 with a remainder of 96.
Write down 2 as next digit of the result. 
Result so far: 925345.78504672
If we subtract 214 from 310, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

The final result is 925345.78504672 with a remainder of 9.6e-08.
