51937006 ÷ 439 
The aim is to understand the frequency of 439 in 51937006.

On to step 1:
439 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 439

Let's proceed to step 2:
51 divided by 439 is 0 with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Grab the next digit (9) from the dividend, add it to 51, then carry on: 519 / 439

Advancing to step 3:
The number 439 fits into 519 1 times, leaving a remainder of 80.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 439 from 519 leaves us with 80.
Take the next digit (3) from the dividend and append it to 80, then repeat: 803 / 439

Let's proceed to step 4:
439 can be fit into 803 1 times, resulting in a remainder of 364.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtracting 439 from 803 leaves us with 364.
Take the next digit (7) from the dividend and append it to 364, then repeat: 3647 / 439

Step 5:
If we divide 3647 by 439, we get 8 and a remainder of 135.
Record the quotient 8 as the next digit in the result. 
Result so far: 118.0
If we subtract 3512 from 3647, we get 135.
Grab the next digit (0) from the dividend, add it to 135, then carry on: 1350 / 439

Step 6:
439 can be fit into 1350 3 times, resulting in a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 1183.0
Deduct 1317 from 1350 and we're left with 33.
Include the next digit (0) from the dividend after 33, then repeat: 330 / 439

Moving on to step 7:
439 can be fit into 330 0 times, resulting in a remainder of 330.
Put 0 as the next digit of the answer. 
Result so far: 11830.0
Subtracting 0 from 330 leaves us with 330.
Fetch the next digit (6) from the dividend, attach it to 330 and continue: 3306 / 439

Moving on to step 8:
439 can be fit into 3306 7 times, resulting in a remainder of 233.
The next digit of our result is 7. 
Result so far: 118307.0
Subtracting 3073 from 3306 leaves us with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Let's proceed to step 9:
The number 439 fits into 2330 5 times, leaving a remainder of 135.
Use 5 as the next digit of our solution. 
Result so far: 118307.5
Subtract 2195 from 2330 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Moving on to step 10:
439 can be fit into 1350 3 times, resulting in a remainder of 33.
The next digit of our result is 3. 
Result so far: 118307.53
Subtract 1317 from 1350 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 11:
When dividing 330 by 439, we get 0 with a remainder of 330.
The next digit of our result is 0. 
Result so far: 118307.53
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.

Going ahead to step 12:
If we divide 3300 by 439, we get 7 and a remainder of 227.
Record the quotient 7 as the next digit in the result. 
Result so far: 118307.5307
If we take 3073 away from 3300, we end up with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Step 13:
The number 439 fits into 2270 5 times, leaving a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 118307.53075
The remainder is 75 after subtracting 2195 from 2270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 14:
When dividing 750 by 439, we get 1 with a remainder of 311.
The number 1 becomes the next digit in our result. 
Result so far: 118307.530751
If we subtract 439 from 750, we get 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Advancing to step 15:
If we divide 3110 by 439, we get 7 and a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 118307.5307517
Subtracting 3073 from 3110 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 16:
439 can be fit into 370 0 times, resulting in a remainder of 370.
Use 0 as the next digit of our solution. 
Result so far: 118307.5307517
Subtracting 0 from 370 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

After the division, we end up with 118307.5307517 and a remainder of 3.7e-07.
