We're dividing 31897129 by 743 
The aim is to understand the frequency of 743 in 31897129.

Advancing to step 1:
3 divided by 743 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 743

Advancing to step 2:
31 divided by 743 is 0 with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Bring next digit (8) of the dividend behind the 31 and repeat the process: 318 / 743

Going ahead to step 3:
When dividing 318 by 743, we get 0 with a remainder of 318.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 318 and we're left with 318.
Include the next digit (9) from the dividend after 318, then repeat: 3189 / 743

Moving on to step 4:
If we divide 3189 by 743, we get 4 and a remainder of 217.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 2972 from 3189 and we're left with 217.
Grab the next digit (7) from the dividend, add it to 217, then carry on: 2177 / 743

Let's proceed to step 5:
If we divide 2177 by 743, we get 2 and a remainder of 691.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Subtract 1486 from 2177 to get 691.
Bring next digit (1) of the dividend behind the 691 and repeat the process: 6911 / 743

Step 6:
When dividing 6911 by 743, we get 9 with a remainder of 224.
Put 9 as the next digit of the answer. 
Result so far: 429.0
If we take 6687 away from 6911, we end up with 224.
Take the next digit (2) from the dividend and append it to 224, then repeat: 2242 / 743

On to step 7:
2242 divided by 743 is 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 4293.0
Deduct 2229 from 2242 and we're left with 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 743

Step 8:
When dividing 139 by 743, we get 0 with a remainder of 139.
The next digit of our result is 0. 
Result so far: 42930.0
Subtract 0 from 139 to get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Let's proceed to step 9:
743 goes into 1390 1 times with a remainder of 647.
Record the quotient 1 as the next digit in the result. 
Result so far: 42930.1
If we take 743 away from 1390, we end up with 647.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6470, and continue the process.

Moving on to step 10:
When dividing 6470 by 743, we get 8 with a remainder of 526.
The number 8 becomes the next digit in our result. 
Result so far: 42930.18
If we subtract 5944 from 6470, we get 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Step 11:
When dividing 5260 by 743, we get 7 with a remainder of 59.
The next digit of our result is 7. 
Result so far: 42930.187
Subtract 5201 from 5260 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 12:
If we divide 590 by 743, we get 0 and a remainder of 590.
Put 0 as the next digit of the answer. 
Result so far: 42930.187
The remainder is 590 after subtracting 0 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Advancing to step 13:
When dividing 5900 by 743, we get 7 with a remainder of 699.
The number 7 becomes the next digit in our result. 
Result so far: 42930.18707
If we subtract 5201 from 5900, we get 699.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6990, and continue the process.

Let's proceed to step 14:
6990 divided by 743 is 9 with a remainder of 303.
Use 9 as the next digit of our solution. 
Result so far: 42930.187079
If we take 6687 away from 6990, we end up with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Going ahead to step 15:
3030 divided by 743 is 4 with a remainder of 58.
Write down 4 as next digit of the result. 
Result so far: 42930.1870794
Deduct 2972 from 3030 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 16:
The number 743 fits into 580 0 times, leaving a remainder of 580.
Put 0 as the next digit of the answer. 
Result so far: 42930.1870794
The remainder is 580 after subtracting 0 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

The final result is 42930.1870794 with a remainder of 5.8e-07.
