We look at the division of 19705298 by 731 
The aim is to understand the frequency of 731 in 19705298.

On to step 1:
1 divided by 731 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 731

Going ahead to step 2:
When dividing 19 by 731, we get 0 with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Bring next digit (7) of the dividend behind the 19 and repeat the process: 197 / 731

On to step 3:
731 can be fit into 197 0 times, resulting in a remainder of 197.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 197 leaves us with 197.
Grab the next digit (0) from the dividend, add it to 197, then carry on: 1970 / 731

On to step 4:
731 goes into 1970 2 times with a remainder of 508.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1462 from 1970 to get 508.
Include the next digit (5) from the dividend after 508, then repeat: 5085 / 731

Step 5:
731 can be fit into 5085 6 times, resulting in a remainder of 699.
Write down 6 as next digit of the result. 
Result so far: 26.0
Deduct 4386 from 5085 and we're left with 699.
Grab the next digit (2) from the dividend, add it to 699, then carry on: 6992 / 731

On to step 6:
If we divide 6992 by 731, we get 9 and a remainder of 413.
Put 9 as the next digit of the answer. 
Result so far: 269.0
Subtract 6579 from 6992 to get 413.
Bring next digit (9) of the dividend behind the 413 and repeat the process: 4139 / 731

On to step 7:
The number 731 fits into 4139 5 times, leaving a remainder of 484.
Use 5 as the next digit of our solution. 
Result so far: 2695.0
If we subtract 3655 from 4139, we get 484.
Fetch the next digit (8) from the dividend, attach it to 484 and continue: 4848 / 731

Let's proceed to step 8:
The number 731 fits into 4848 6 times, leaving a remainder of 462.
Put 6 as the next digit of the answer. 
Result so far: 26956.0
Subtract 4386 from 4848 to get 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Advancing to step 9:
731 goes into 4620 6 times with a remainder of 234.
Use 6 as the next digit of our solution. 
Result so far: 26956.6
Subtract 4386 from 4620 to get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Let's proceed to step 10:
731 goes into 2340 3 times with a remainder of 147.
The number 3 becomes the next digit in our result. 
Result so far: 26956.63
Subtracting 2193 from 2340 leaves us with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Moving on to step 11:
1470 divided by 731 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 26956.632
The remainder is 8 after subtracting 1462 from 1470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
When dividing 80 by 731, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 26956.632
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
When dividing 800 by 731, we get 1 with a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 26956.63201
Deduct 731 from 800 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 14:
731 goes into 690 0 times with a remainder of 690.
Put 0 as the next digit of the answer. 
Result so far: 26956.63201
The remainder is 690 after subtracting 0 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Going ahead to step 15:
When dividing 6900 by 731, we get 9 with a remainder of 321.
Put 9 as the next digit of the answer. 
Result so far: 26956.6320109
Subtract 6579 from 6900 to get 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Let's proceed to step 16:
731 goes into 3210 4 times with a remainder of 286.
The number 4 becomes the next digit in our result. 
Result so far: 26956.63201094
The remainder is 286 after subtracting 2924 from 3210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

After the division, we end up with 26956.63201094 and a remainder of 2.86e-07.
