We look at the division of 71202583 by 731 
The aim is to understand the frequency of 731 in 71202583.

Step 1:
If we divide 7 by 731, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 731

Advancing to step 2:
When dividing 71 by 731, we get 0 with a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Bring next digit (2) of the dividend behind the 71 and repeat the process: 712 / 731

Advancing to step 3:
If we divide 712 by 731, we get 0 and a remainder of 712.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 712 to get 712.
Take the next digit (0) from the dividend and append it to 712, then repeat: 7120 / 731

Going ahead to step 4:
If we divide 7120 by 731, we get 9 and a remainder of 541.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 6579 away from 7120, we end up with 541.
Include the next digit (2) from the dividend after 541, then repeat: 5412 / 731

Let's proceed to step 5:
When dividing 5412 by 731, we get 7 with a remainder of 295.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
If we take 5117 away from 5412, we end up with 295.
Grab the next digit (5) from the dividend, add it to 295, then carry on: 2955 / 731

Step 6:
When dividing 2955 by 731, we get 4 with a remainder of 31.
The number 4 becomes the next digit in our result. 
Result so far: 974.0
If we take 2924 away from 2955, we end up with 31.
Bring next digit (8) of the dividend behind the 31 and repeat the process: 318 / 731

Step 7:
If we divide 318 by 731, we get 0 and a remainder of 318.
Record the quotient 0 as the next digit in the result. 
Result so far: 9740.0
Subtract 0 from 318 to get 318.
Grab the next digit (3) from the dividend, add it to 318, then carry on: 3183 / 731

Let's proceed to step 8:
731 can be fit into 3183 4 times, resulting in a remainder of 259.
The number 4 becomes the next digit in our result. 
Result so far: 97404.0
If we subtract 2924 from 3183, we get 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Advancing to step 9:
731 can be fit into 2590 3 times, resulting in a remainder of 397.
Record the quotient 3 as the next digit in the result. 
Result so far: 97404.3
If we subtract 2193 from 2590, we get 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Step 10:
731 goes into 3970 5 times with a remainder of 315.
Use 5 as the next digit of our solution. 
Result so far: 97404.35
Subtract 3655 from 3970 to get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

On to step 11:
731 can be fit into 3150 4 times, resulting in a remainder of 226.
The next digit of our result is 4. 
Result so far: 97404.354
The remainder is 226 after subtracting 2924 from 3150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Step 12:
The number 731 fits into 2260 3 times, leaving a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 97404.3543
Deduct 2193 from 2260 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 13:
731 can be fit into 670 0 times, resulting in a remainder of 670.
The next digit of our result is 0. 
Result so far: 97404.3543
Subtract 0 from 670 to get 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Going ahead to step 14:
The number 731 fits into 6700 9 times, leaving a remainder of 121.
The next digit of our result is 9. 
Result so far: 97404.354309
Deduct 6579 from 6700 and we're left with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Let's proceed to step 15:
731 can be fit into 1210 1 times, resulting in a remainder of 479.
The next digit of our result is 1. 
Result so far: 97404.3543091
Deduct 731 from 1210 and we're left with 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Step 16:
The number 731 fits into 4790 6 times, leaving a remainder of 404.
The number 6 becomes the next digit in our result. 
Result so far: 97404.35430916
If we subtract 4386 from 4790, we get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Our division results in 97404.35430916 with a remaining 4.04e-07.
