We look at the division of 65936227 by 931 
The aim is to understand the frequency of 931 in 65936227.

Let's proceed to step 1:
6 divided by 931 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 931

Moving on to step 2:
The number 931 fits into 65 0 times, leaving a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Include the next digit (9) from the dividend after 65, then repeat: 659 / 931

Advancing to step 3:
The number 931 fits into 659 0 times, leaving a remainder of 659.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 659, we get 659.
Grab the next digit (3) from the dividend, add it to 659, then carry on: 6593 / 931

On to step 4:
The number 931 fits into 6593 7 times, leaving a remainder of 76.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 6517 from 6593 leaves us with 76.
Fetch the next digit (6) from the dividend, attach it to 76 and continue: 766 / 931

Going ahead to step 5:
931 can be fit into 766 0 times, resulting in a remainder of 766.
Use 0 as the next digit of our solution. 
Result so far: 70.0
If we subtract 0 from 766, we get 766.
Bring next digit (2) of the dividend behind the 766 and repeat the process: 7662 / 931

Going ahead to step 6:
7662 divided by 931 is 8 with a remainder of 214.
The number 8 becomes the next digit in our result. 
Result so far: 708.0
If we take 7448 away from 7662, we end up with 214.
Fetch the next digit (2) from the dividend, attach it to 214 and continue: 2142 / 931

Moving on to step 7:
2142 divided by 931 is 2 with a remainder of 280.
The next digit of our result is 2. 
Result so far: 7082.0
The remainder is 280 after subtracting 1862 from 2142.
Append the next digit (7) from the dividend to 280 and continue with: 2807 / 931

Moving on to step 8:
The number 931 fits into 2807 3 times, leaving a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 70823.0
If we take 2793 away from 2807, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
When dividing 140 by 931, we get 0 with a remainder of 140.
The next digit of our result is 0. 
Result so far: 70823.0
If we take 0 away from 140, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 10:
931 goes into 1400 1 times with a remainder of 469.
The next digit of our result is 1. 
Result so far: 70823.01
If we subtract 931 from 1400, we get 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Moving on to step 11:
If we divide 4690 by 931, we get 5 and a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 70823.015
Subtracting 4655 from 4690 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 12:
931 can be fit into 350 0 times, resulting in a remainder of 350.
Use 0 as the next digit of our solution. 
Result so far: 70823.015
If we subtract 0 from 350, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 13:
931 goes into 3500 3 times with a remainder of 707.
Use 3 as the next digit of our solution. 
Result so far: 70823.01503
If we subtract 2793 from 3500, we get 707.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7070, and continue the process.

Going ahead to step 14:
If we divide 7070 by 931, we get 7 and a remainder of 553.
The number 7 becomes the next digit in our result. 
Result so far: 70823.015037
Subtracting 6517 from 7070 leaves us with 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Let's proceed to step 15:
931 can be fit into 5530 5 times, resulting in a remainder of 875.
Record the quotient 5 as the next digit in the result. 
Result so far: 70823.0150375
Subtract 4655 from 5530 to get 875.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8750, and continue the process.

Step 16:
If we divide 8750 by 931, we get 9 and a remainder of 371.
Record the quotient 9 as the next digit in the result. 
Result so far: 70823.01503759
If we take 8379 away from 8750, we end up with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Our division results in 70823.01503759 with a remaining 3.71e-07.
