We're dividing 42743531 by 737 
The aim is to understand the frequency of 737 in 42743531.

On to step 1:
If we divide 4 by 737, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 737

Let's proceed to step 2:
42 divided by 737 is 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Take the next digit (7) from the dividend and append it to 42, then repeat: 427 / 737

Step 3:
737 can be fit into 427 0 times, resulting in a remainder of 427.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 427, we get 427.
Append the next digit (4) from the dividend to 427 and continue with: 4274 / 737

Moving on to step 4:
When dividing 4274 by 737, we get 5 with a remainder of 589.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 589 after subtracting 3685 from 4274.
Grab the next digit (3) from the dividend, add it to 589, then carry on: 5893 / 737

Step 5:
The number 737 fits into 5893 7 times, leaving a remainder of 734.
The next digit of our result is 7. 
Result so far: 57.0
Deduct 5159 from 5893 and we're left with 734.
Grab the next digit (5) from the dividend, add it to 734, then carry on: 7345 / 737

On to step 6:
737 goes into 7345 9 times with a remainder of 712.
The number 9 becomes the next digit in our result. 
Result so far: 579.0
Subtracting 6633 from 7345 leaves us with 712.
Fetch the next digit (3) from the dividend, attach it to 712 and continue: 7123 / 737

Step 7:
737 goes into 7123 9 times with a remainder of 490.
The next digit of our result is 9. 
Result so far: 5799.0
If we take 6633 away from 7123, we end up with 490.
Bring next digit (1) of the dividend behind the 490 and repeat the process: 4901 / 737

On to step 8:
737 goes into 4901 6 times with a remainder of 479.
Record the quotient 6 as the next digit in the result. 
Result so far: 57996.0
If we subtract 4422 from 4901, we get 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Moving on to step 9:
737 can be fit into 4790 6 times, resulting in a remainder of 368.
The next digit of our result is 6. 
Result so far: 57996.6
If we subtract 4422 from 4790, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Going ahead to step 10:
737 can be fit into 3680 4 times, resulting in a remainder of 732.
Use 4 as the next digit of our solution. 
Result so far: 57996.64
If we subtract 2948 from 3680, we get 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

Let's proceed to step 11:
When dividing 7320 by 737, we get 9 with a remainder of 687.
Record the quotient 9 as the next digit in the result. 
Result so far: 57996.649
If we subtract 6633 from 7320, we get 687.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6870, and continue the process.

Advancing to step 12:
737 goes into 6870 9 times with a remainder of 237.
The next digit of our result is 9. 
Result so far: 57996.6499
Subtracting 6633 from 6870 leaves us with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

The quotient of the division is 57996.6499, and the remainder is 0.00237.
