We look at the division of 91658993 by 907 
The aim is to understand the frequency of 907 in 91658993.

Step 1:
907 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 907

Advancing to step 2:
The number 907 fits into 91 0 times, leaving a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Append the next digit (6) from the dividend to 91 and continue with: 916 / 907

Let's proceed to step 3:
The number 907 fits into 916 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 907 from 916 to get 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 907

Let's proceed to step 4:
907 can be fit into 95 0 times, resulting in a remainder of 95.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 95, we end up with 95.
Take the next digit (8) from the dividend and append it to 95, then repeat: 958 / 907

Let's proceed to step 5:
If we divide 958 by 907, we get 1 and a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
Subtracting 907 from 958 leaves us with 51.
Take the next digit (9) from the dividend and append it to 51, then repeat: 519 / 907

Let's proceed to step 6:
519 divided by 907 is 0 with a remainder of 519.
Record the quotient 0 as the next digit in the result. 
Result so far: 1010.0
Deduct 0 from 519 and we're left with 519.
Append the next digit (9) from the dividend to 519 and continue with: 5199 / 907

Step 7:
907 can be fit into 5199 5 times, resulting in a remainder of 664.
Put 5 as the next digit of the answer. 
Result so far: 10105.0
If we take 4535 away from 5199, we end up with 664.
Bring next digit (3) of the dividend behind the 664 and repeat the process: 6643 / 907

Going ahead to step 8:
If we divide 6643 by 907, we get 7 and a remainder of 294.
Use 7 as the next digit of our solution. 
Result so far: 101057.0
The remainder is 294 after subtracting 6349 from 6643.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Moving on to step 9:
The number 907 fits into 2940 3 times, leaving a remainder of 219.
The next digit of our result is 3. 
Result so far: 101057.3
Deduct 2721 from 2940 and we're left with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Advancing to step 10:
When dividing 2190 by 907, we get 2 with a remainder of 376.
The number 2 becomes the next digit in our result. 
Result so far: 101057.32
Subtracting 1814 from 2190 leaves us with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Advancing to step 11:
3760 divided by 907 is 4 with a remainder of 132.
Put 4 as the next digit of the answer. 
Result so far: 101057.324
If we subtract 3628 from 3760, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 12:
The number 907 fits into 1320 1 times, leaving a remainder of 413.
Record the quotient 1 as the next digit in the result. 
Result so far: 101057.3241
If we take 907 away from 1320, we end up with 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Step 13:
When dividing 4130 by 907, we get 4 with a remainder of 502.
Write down 4 as next digit of the result. 
Result so far: 101057.32414
The remainder is 502 after subtracting 3628 from 4130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Let's proceed to step 14:
The number 907 fits into 5020 5 times, leaving a remainder of 485.
Write down 5 as next digit of the result. 
Result so far: 101057.324145
Subtract 4535 from 5020 to get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Advancing to step 15:
When dividing 4850 by 907, we get 5 with a remainder of 315.
The next digit of our result is 5. 
Result so far: 101057.3241455
The remainder is 315 after subtracting 4535 from 4850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Our division results in 101057.3241455 with a remaining 3.15e-06.
