We look at the division of 31443065 by 737 
The aim is to understand the frequency of 737 in 31443065.

Let's proceed to step 1:
737 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 737

Step 2:
When dividing 31 by 737, we get 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Fetch the next digit (4) from the dividend, attach it to 31 and continue: 314 / 737

Moving on to step 3:
314 divided by 737 is 0 with a remainder of 314.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 314, we get 314.
Include the next digit (4) from the dividend after 314, then repeat: 3144 / 737

Let's proceed to step 4:
When dividing 3144 by 737, we get 4 with a remainder of 196.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 2948 from 3144 leaves us with 196.
Bring next digit (3) of the dividend behind the 196 and repeat the process: 1963 / 737

Advancing to step 5:
The number 737 fits into 1963 2 times, leaving a remainder of 489.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
The remainder is 489 after subtracting 1474 from 1963.
Include the next digit (0) from the dividend after 489, then repeat: 4890 / 737

Let's proceed to step 6:
The number 737 fits into 4890 6 times, leaving a remainder of 468.
Write down 6 as next digit of the result. 
Result so far: 426.0
If we take 4422 away from 4890, we end up with 468.
Take the next digit (6) from the dividend and append it to 468, then repeat: 4686 / 737

Advancing to step 7:
When dividing 4686 by 737, we get 6 with a remainder of 264.
The number 6 becomes the next digit in our result. 
Result so far: 4266.0
Subtracting 4422 from 4686 leaves us with 264.
Fetch the next digit (5) from the dividend, attach it to 264 and continue: 2645 / 737

Advancing to step 8:
737 goes into 2645 3 times with a remainder of 434.
Record the quotient 3 as the next digit in the result. 
Result so far: 42663.0
The remainder is 434 after subtracting 2211 from 2645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Step 9:
If we divide 4340 by 737, we get 5 and a remainder of 655.
The number 5 becomes the next digit in our result. 
Result so far: 42663.5
Subtracting 3685 from 4340 leaves us with 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Advancing to step 10:
6550 divided by 737 is 8 with a remainder of 654.
Use 8 as the next digit of our solution. 
Result so far: 42663.58
Subtracting 5896 from 6550 leaves us with 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Moving on to step 11:
737 can be fit into 6540 8 times, resulting in a remainder of 644.
The number 8 becomes the next digit in our result. 
Result so far: 42663.588
Subtract 5896 from 6540 to get 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

The quotient of the division is 42663.588, and the remainder is 0.0644.
