38691053 divided by 437 
The aim is to understand the frequency of 437 in 38691053.

Let's proceed to step 1:
437 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 437

Advancing to step 2:
437 can be fit into 38 0 times, resulting in a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Include the next digit (6) from the dividend after 38, then repeat: 386 / 437

On to step 3:
The number 437 fits into 386 0 times, leaving a remainder of 386.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 386 to get 386.
Append the next digit (9) from the dividend to 386 and continue with: 3869 / 437

Going ahead to step 4:
The number 437 fits into 3869 8 times, leaving a remainder of 373.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 373 after subtracting 3496 from 3869.
Bring next digit (1) of the dividend behind the 373 and repeat the process: 3731 / 437

Advancing to step 5:
If we divide 3731 by 437, we get 8 and a remainder of 235.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
If we subtract 3496 from 3731, we get 235.
Append the next digit (0) from the dividend to 235 and continue with: 2350 / 437

Going ahead to step 6:
When dividing 2350 by 437, we get 5 with a remainder of 165.
Write down 5 as next digit of the result. 
Result so far: 885.0
If we take 2185 away from 2350, we end up with 165.
Take the next digit (5) from the dividend and append it to 165, then repeat: 1655 / 437

Moving on to step 7:
437 goes into 1655 3 times with a remainder of 344.
The number 3 becomes the next digit in our result. 
Result so far: 8853.0
Subtracting 1311 from 1655 leaves us with 344.
Fetch the next digit (3) from the dividend, attach it to 344 and continue: 3443 / 437

Going ahead to step 8:
437 goes into 3443 7 times with a remainder of 384.
Put 7 as the next digit of the answer. 
Result so far: 88537.0
The remainder is 384 after subtracting 3059 from 3443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 9:
3840 divided by 437 is 8 with a remainder of 344.
Record the quotient 8 as the next digit in the result. 
Result so far: 88537.8
Deduct 3496 from 3840 and we're left with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Moving on to step 10:
437 goes into 3440 7 times with a remainder of 381.
Use 7 as the next digit of our solution. 
Result so far: 88537.87
If we take 3059 away from 3440, we end up with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Let's proceed to step 11:
The number 437 fits into 3810 8 times, leaving a remainder of 314.
Put 8 as the next digit of the answer. 
Result so far: 88537.878
The remainder is 314 after subtracting 3496 from 3810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Step 12:
437 can be fit into 3140 7 times, resulting in a remainder of 81.
Write down 7 as next digit of the result. 
Result so far: 88537.8787
Subtract 3059 from 3140 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 13:
If we divide 810 by 437, we get 1 and a remainder of 373.
The number 1 becomes the next digit in our result. 
Result so far: 88537.87871
The remainder is 373 after subtracting 437 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Step 14:
437 goes into 3730 8 times with a remainder of 234.
The number 8 becomes the next digit in our result. 
Result so far: 88537.878718
If we subtract 3496 from 3730, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

On to step 15:
437 goes into 2340 5 times with a remainder of 155.
Use 5 as the next digit of our solution. 
Result so far: 88537.8787185
The remainder is 155 after subtracting 2185 from 2340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 16:
437 can be fit into 1550 3 times, resulting in a remainder of 239.
Use 3 as the next digit of our solution. 
Result so far: 88537.87871853
If we subtract 1311 from 1550, we get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Our division results in 88537.87871853 with a remaining 2.39e-07.
