We look at the division of 38739363 by 738 
The aim is to understand the frequency of 738 in 38739363.

On to step 1:
3 divided by 738 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 738

Moving on to step 2:
If we divide 38 by 738, we get 0 and a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Include the next digit (7) from the dividend after 38, then repeat: 387 / 738

On to step 3:
738 can be fit into 387 0 times, resulting in a remainder of 387.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 387, we get 387.
Grab the next digit (3) from the dividend, add it to 387, then carry on: 3873 / 738

Step 4:
The number 738 fits into 3873 5 times, leaving a remainder of 183.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 3690 from 3873, we get 183.
Append the next digit (9) from the dividend to 183 and continue with: 1839 / 738

Let's proceed to step 5:
738 goes into 1839 2 times with a remainder of 363.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
The remainder is 363 after subtracting 1476 from 1839.
Append the next digit (3) from the dividend to 363 and continue with: 3633 / 738

On to step 6:
The number 738 fits into 3633 4 times, leaving a remainder of 681.
Use 4 as the next digit of our solution. 
Result so far: 524.0
If we subtract 2952 from 3633, we get 681.
Grab the next digit (6) from the dividend, add it to 681, then carry on: 6816 / 738

Step 7:
If we divide 6816 by 738, we get 9 and a remainder of 174.
Put 9 as the next digit of the answer. 
Result so far: 5249.0
If we subtract 6642 from 6816, we get 174.
Append the next digit (3) from the dividend to 174 and continue with: 1743 / 738

Going ahead to step 8:
The number 738 fits into 1743 2 times, leaving a remainder of 267.
Write down 2 as next digit of the result. 
Result so far: 52492.0
Deduct 1476 from 1743 and we're left with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Advancing to step 9:
2670 divided by 738 is 3 with a remainder of 456.
Put 3 as the next digit of the answer. 
Result so far: 52492.3
Deduct 2214 from 2670 and we're left with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Let's proceed to step 10:
When dividing 4560 by 738, we get 6 with a remainder of 132.
Put 6 as the next digit of the answer. 
Result so far: 52492.36
If we take 4428 away from 4560, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 11:
The number 738 fits into 1320 1 times, leaving a remainder of 582.
The number 1 becomes the next digit in our result. 
Result so far: 52492.361
If we subtract 738 from 1320, we get 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

Advancing to step 12:
When dividing 5820 by 738, we get 7 with a remainder of 654.
The number 7 becomes the next digit in our result. 
Result so far: 52492.3617
Subtracting 5166 from 5820 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.

Going ahead to step 13:
If we divide 6540 by 738, we get 8 and a remainder of 636.
Put 8 as the next digit of the answer. 
Result so far: 52492.36178
If we subtract 5904 from 6540, we get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

On to step 14:
738 can be fit into 6360 8 times, resulting in a remainder of 456.
Record the quotient 8 as the next digit in the result. 
Result so far: 52492.361788
If we take 5904 away from 6360, we end up with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

The final result is 52492.361788 with a remainder of 4.56e-05.
