We look at the division of 91748165 by 731 
The aim is to understand the frequency of 731 in 91748165.

Moving on to step 1:
731 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 731

On to step 2:
When dividing 91 by 731, we get 0 with a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Bring next digit (7) of the dividend behind the 91 and repeat the process: 917 / 731

Advancing to step 3:
When dividing 917 by 731, we get 1 with a remainder of 186.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 731 away from 917, we end up with 186.
Grab the next digit (4) from the dividend, add it to 186, then carry on: 1864 / 731

On to step 4:
When dividing 1864 by 731, we get 2 with a remainder of 402.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 1462 from 1864 and we're left with 402.
Take the next digit (8) from the dividend and append it to 402, then repeat: 4028 / 731

Going ahead to step 5:
The number 731 fits into 4028 5 times, leaving a remainder of 373.
The next digit of our result is 5. 
Result so far: 125.0
If we subtract 3655 from 4028, we get 373.
Grab the next digit (1) from the dividend, add it to 373, then carry on: 3731 / 731

Advancing to step 6:
The number 731 fits into 3731 5 times, leaving a remainder of 76.
The number 5 becomes the next digit in our result. 
Result so far: 1255.0
Subtracting 3655 from 3731 leaves us with 76.
Fetch the next digit (6) from the dividend, attach it to 76 and continue: 766 / 731

Let's proceed to step 7:
If we divide 766 by 731, we get 1 and a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 12551.0
If we subtract 731 from 766, we get 35.
Grab the next digit (5) from the dividend, add it to 35, then carry on: 355 / 731

Step 8:
355 divided by 731 is 0 with a remainder of 355.
The number 0 becomes the next digit in our result. 
Result so far: 125510.0
Subtract 0 from 355 to get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Advancing to step 9:
The number 731 fits into 3550 4 times, leaving a remainder of 626.
The number 4 becomes the next digit in our result. 
Result so far: 125510.4
Deduct 2924 from 3550 and we're left with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Step 10:
731 can be fit into 6260 8 times, resulting in a remainder of 412.
Record the quotient 8 as the next digit in the result. 
Result so far: 125510.48
Subtracting 5848 from 6260 leaves us with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Let's proceed to step 11:
731 goes into 4120 5 times with a remainder of 465.
Put 5 as the next digit of the answer. 
Result so far: 125510.485
Deduct 3655 from 4120 and we're left with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Going ahead to step 12:
4650 divided by 731 is 6 with a remainder of 264.
Use 6 as the next digit of our solution. 
Result so far: 125510.4856
The remainder is 264 after subtracting 4386 from 4650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 13:
If we divide 2640 by 731, we get 3 and a remainder of 447.
The next digit of our result is 3. 
Result so far: 125510.48563
Subtract 2193 from 2640 to get 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Step 14:
When dividing 4470 by 731, we get 6 with a remainder of 84.
The next digit of our result is 6. 
Result so far: 125510.485636
Deduct 4386 from 4470 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 15:
The number 731 fits into 840 1 times, leaving a remainder of 109.
The number 1 becomes the next digit in our result. 
Result so far: 125510.4856361
If we subtract 731 from 840, we get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Advancing to step 16:
731 can be fit into 1090 1 times, resulting in a remainder of 359.
Use 1 as the next digit of our solution. 
Result so far: 125510.48563611
Subtracting 731 from 1090 leaves us with 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

After the division, we end up with 125510.48563611 and a remainder of 3.59e-07.
