15538201 divided by 439 
The aim is to understand the frequency of 439 in 15538201.

Going ahead to step 1:
The number 439 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 439

Advancing to step 2:
439 goes into 15 0 times with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 439

Advancing to step 3:
If we divide 155 by 439, we get 0 and a remainder of 155.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 155, we end up with 155.
Fetch the next digit (3) from the dividend, attach it to 155 and continue: 1553 / 439

On to step 4:
1553 divided by 439 is 3 with a remainder of 236.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 1317 from 1553 leaves us with 236.
Fetch the next digit (8) from the dividend, attach it to 236 and continue: 2368 / 439

Step 5:
439 goes into 2368 5 times with a remainder of 173.
Put 5 as the next digit of the answer. 
Result so far: 35.0
If we take 2195 away from 2368, we end up with 173.
Bring next digit (2) of the dividend behind the 173 and repeat the process: 1732 / 439

Advancing to step 6:
1732 divided by 439 is 3 with a remainder of 415.
Record the quotient 3 as the next digit in the result. 
Result so far: 353.0
If we take 1317 away from 1732, we end up with 415.
Include the next digit (0) from the dividend after 415, then repeat: 4150 / 439

Advancing to step 7:
If we divide 4150 by 439, we get 9 and a remainder of 199.
Record the quotient 9 as the next digit in the result. 
Result so far: 3539.0
Subtracting 3951 from 4150 leaves us with 199.
Include the next digit (1) from the dividend after 199, then repeat: 1991 / 439

Let's proceed to step 8:
439 goes into 1991 4 times with a remainder of 235.
Write down 4 as next digit of the result. 
Result so far: 35394.0
If we subtract 1756 from 1991, we get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Going ahead to step 9:
When dividing 2350 by 439, we get 5 with a remainder of 155.
Use 5 as the next digit of our solution. 
Result so far: 35394.5
Subtract 2195 from 2350 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Advancing to step 10:
The number 439 fits into 1550 3 times, leaving a remainder of 233.
The number 3 becomes the next digit in our result. 
Result so far: 35394.53
If we subtract 1317 from 1550, we get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Going ahead to step 11:
The number 439 fits into 2330 5 times, leaving a remainder of 135.
Put 5 as the next digit of the answer. 
Result so far: 35394.535
The remainder is 135 after subtracting 2195 from 2330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 12:
If we divide 1350 by 439, we get 3 and a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 35394.5353
Subtracting 1317 from 1350 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 13:
330 divided by 439 is 0 with a remainder of 330.
The number 0 becomes the next digit in our result. 
Result so far: 35394.5353
Deduct 0 from 330 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 14:
439 can be fit into 3300 7 times, resulting in a remainder of 227.
The next digit of our result is 7. 
Result so far: 35394.535307
The remainder is 227 after subtracting 3073 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

On to step 15:
2270 divided by 439 is 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 35394.5353075
If we subtract 2195 from 2270, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 16:
439 goes into 750 1 times with a remainder of 311.
Record the quotient 1 as the next digit in the result. 
Result so far: 35394.53530751
Deduct 439 from 750 and we're left with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Our division results in 35394.53530751 with a remaining 3.11e-07.
