We look at the division of 31006951 by 693 
The aim is to understand the frequency of 693 in 31006951.

Going ahead to step 1:
3 divided by 693 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 693

Moving on to step 2:
31 divided by 693 is 0 with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 693

Advancing to step 3:
When dividing 310 by 693, we get 0 with a remainder of 310.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 310, we end up with 310.
Fetch the next digit (0) from the dividend, attach it to 310 and continue: 3100 / 693

Let's proceed to step 4:
The number 693 fits into 3100 4 times, leaving a remainder of 328.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 2772 from 3100, we get 328.
Include the next digit (6) from the dividend after 328, then repeat: 3286 / 693

Moving on to step 5:
693 goes into 3286 4 times with a remainder of 514.
Write down 4 as next digit of the result. 
Result so far: 44.0
Deduct 2772 from 3286 and we're left with 514.
Include the next digit (9) from the dividend after 514, then repeat: 5149 / 693

Going ahead to step 6:
5149 divided by 693 is 7 with a remainder of 298.
Record the quotient 7 as the next digit in the result. 
Result so far: 447.0
Deduct 4851 from 5149 and we're left with 298.
Fetch the next digit (5) from the dividend, attach it to 298 and continue: 2985 / 693

On to step 7:
If we divide 2985 by 693, we get 4 and a remainder of 213.
Write down 4 as next digit of the result. 
Result so far: 4474.0
The remainder is 213 after subtracting 2772 from 2985.
Include the next digit (1) from the dividend after 213, then repeat: 2131 / 693

On to step 8:
When dividing 2131 by 693, we get 3 with a remainder of 52.
Record the quotient 3 as the next digit in the result. 
Result so far: 44743.0
Subtracting 2079 from 2131 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 9:
If we divide 520 by 693, we get 0 and a remainder of 520.
The number 0 becomes the next digit in our result. 
Result so far: 44743.0
If we take 0 away from 520, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 10:
The number 693 fits into 5200 7 times, leaving a remainder of 349.
The next digit of our result is 7. 
Result so far: 44743.07
If we subtract 4851 from 5200, we get 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Advancing to step 11:
693 goes into 3490 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 44743.075
Deduct 3465 from 3490 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 12:
693 goes into 250 0 times with a remainder of 250.
The number 0 becomes the next digit in our result. 
Result so far: 44743.075
Subtract 0 from 250 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 13:
If we divide 2500 by 693, we get 3 and a remainder of 421.
Write down 3 as next digit of the result. 
Result so far: 44743.07503
If we take 2079 away from 2500, we end up with 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

Going ahead to step 14:
When dividing 4210 by 693, we get 6 with a remainder of 52.
The next digit of our result is 6. 
Result so far: 44743.075036
Subtract 4158 from 4210 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 15:
693 can be fit into 520 0 times, resulting in a remainder of 520.
The number 0 becomes the next digit in our result. 
Result so far: 44743.075036
The remainder is 520 after subtracting 0 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 16:
693 can be fit into 5200 7 times, resulting in a remainder of 349.
Use 7 as the next digit of our solution. 
Result so far: 44743.07503607
Subtracting 4851 from 5200 leaves us with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

The final result is 44743.07503607 with a remainder of 3.49e-07.
