We're dividing 31990278 by 738 
The aim is to understand the frequency of 738 in 31990278.

Going ahead to step 1:
3 divided by 738 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 738

Step 2:
If we divide 31 by 738, we get 0 and a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Fetch the next digit (9) from the dividend, attach it to 31 and continue: 319 / 738

Step 3:
319 divided by 738 is 0 with a remainder of 319.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 319, we get 319.
Append the next digit (9) from the dividend to 319 and continue with: 3199 / 738

On to step 4:
If we divide 3199 by 738, we get 4 and a remainder of 247.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 247 after subtracting 2952 from 3199.
Include the next digit (0) from the dividend after 247, then repeat: 2470 / 738

Advancing to step 5:
738 goes into 2470 3 times with a remainder of 256.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Subtracting 2214 from 2470 leaves us with 256.
Take the next digit (2) from the dividend and append it to 256, then repeat: 2562 / 738

Moving on to step 6:
When dividing 2562 by 738, we get 3 with a remainder of 348.
Use 3 as the next digit of our solution. 
Result so far: 433.0
Deduct 2214 from 2562 and we're left with 348.
Grab the next digit (7) from the dividend, add it to 348, then carry on: 3487 / 738

Going ahead to step 7:
The number 738 fits into 3487 4 times, leaving a remainder of 535.
Write down 4 as next digit of the result. 
Result so far: 4334.0
The remainder is 535 after subtracting 2952 from 3487.
Grab the next digit (8) from the dividend, add it to 535, then carry on: 5358 / 738

Step 8:
738 goes into 5358 7 times with a remainder of 192.
Write down 7 as next digit of the result. 
Result so far: 43347.0
Subtracting 5166 from 5358 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 9:
738 can be fit into 1920 2 times, resulting in a remainder of 444.
Put 2 as the next digit of the answer. 
Result so far: 43347.2
The remainder is 444 after subtracting 1476 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Step 10:
738 goes into 4440 6 times with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 43347.26
If we subtract 4428 from 4440, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 11:
738 can be fit into 120 0 times, resulting in a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 43347.26
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 12:
When dividing 1200 by 738, we get 1 with a remainder of 462.
Record the quotient 1 as the next digit in the result. 
Result so far: 43347.2601
If we subtract 738 from 1200, we get 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Let's proceed to step 13:
If we divide 4620 by 738, we get 6 and a remainder of 192.
The number 6 becomes the next digit in our result. 
Result so far: 43347.26016
If we subtract 4428 from 4620, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 14:
738 goes into 1920 2 times with a remainder of 444.
Record the quotient 2 as the next digit in the result. 
Result so far: 43347.260162
The remainder is 444 after subtracting 1476 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

On to step 15:
738 goes into 4440 6 times with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 43347.2601626
Deduct 4428 from 4440 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 16:
120 divided by 738 is 0 with a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 43347.2601626
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

After the division, we end up with 43347.2601626 and a remainder of 1.2e-07.
