We divide 31908586 by 743
The aim is to understand the frequency of 743 in 31908586.

Moving on to step 1:
743 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 743

Let's proceed to step 2:
743 goes into 31 0 times with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Bring next digit (9) of the dividend behind the 31 and repeat the process: 319 / 743

Let's proceed to step 3:
743 goes into 319 0 times with a remainder of 319.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 319 leaves us with 319.
Append the next digit (0) from the dividend to 319 and continue with: 3190 / 743

Let's proceed to step 4:
743 can be fit into 3190 4 times, resulting in a remainder of 218.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 2972 from 3190 leaves us with 218.
Take the next digit (8) from the dividend and append it to 218, then repeat: 2188 / 743

Let's proceed to step 5:
When dividing 2188 by 743, we get 2 with a remainder of 702.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
The remainder is 702 after subtracting 1486 from 2188.
Include the next digit (5) from the dividend after 702, then repeat: 7025 / 743

Going ahead to step 6:
When dividing 7025 by 743, we get 9 with a remainder of 338.
Put 9 as the next digit of the answer. 
Result so far: 429.0
The remainder is 338 after subtracting 6687 from 7025.
Take the next digit (8) from the dividend and append it to 338, then repeat: 3388 / 743

Advancing to step 7:
743 goes into 3388 4 times with a remainder of 416.
Record the quotient 4 as the next digit in the result. 
Result so far: 4294.0
Subtracting 2972 from 3388 leaves us with 416.
Include the next digit (6) from the dividend after 416, then repeat: 4166 / 743

Advancing to step 8:
743 can be fit into 4166 5 times, resulting in a remainder of 451.
Record the quotient 5 as the next digit in the result. 
Result so far: 42945.0
Subtracting 3715 from 4166 leaves us with 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

On to step 9:
743 goes into 4510 6 times with a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 42945.6
Subtract 4458 from 4510 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.

Advancing to step 10:
520 divided by 743 is 0 with a remainder of 520.
The number 0 becomes the next digit in our result. 
Result so far: 42945.6
If we subtract 0 from 520, we get 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 11:
The number 743 fits into 5200 6 times, leaving a remainder of 742.
Record the quotient 6 as the next digit in the result. 
Result so far: 42945.606
Subtracting 4458 from 5200 leaves us with 742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

Going ahead to step 12:
The number 743 fits into 7420 9 times, leaving a remainder of 733.
Use 9 as the next digit of our solution. 
Result so far: 42945.6069
If we take 6687 away from 7420, we end up with 733.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7330, and continue the process.

Let's proceed to step 13:
7330 divided by 743 is 9 with a remainder of 643.
The next digit of our result is 9. 
Result so far: 42945.60699
Subtract 6687 from 7330 to get 643.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6430, and continue the process.

After the division, we end up with 42945.60699 and a remainder of 0.000643.
