We look at the division of 89937700 by 439 
The aim is to understand the frequency of 439 in 89937700.

Going ahead to step 1:
When dividing 8 by 439, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 439

Going ahead to step 2:
439 can be fit into 89 0 times, resulting in a remainder of 89.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 89, we get 89.
Take the next digit (9) from the dividend and append it to 89, then repeat: 899 / 439

Going ahead to step 3:
The number 439 fits into 899 2 times, leaving a remainder of 21.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 878 from 899 leaves us with 21.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 439

Advancing to step 4:
439 can be fit into 213 0 times, resulting in a remainder of 213.
Write down 0 as next digit of the result. 
Result so far: 20.0
Deduct 0 from 213 and we're left with 213.
Bring next digit (7) of the dividend behind the 213 and repeat the process: 2137 / 439

Going ahead to step 5:
439 can be fit into 2137 4 times, resulting in a remainder of 381.
Use 4 as the next digit of our solution. 
Result so far: 204.0
Subtract 1756 from 2137 to get 381.
Append the next digit (7) from the dividend to 381 and continue with: 3817 / 439

Let's proceed to step 6:
If we divide 3817 by 439, we get 8 and a remainder of 305.
Record the quotient 8 as the next digit in the result. 
Result so far: 2048.0
If we subtract 3512 from 3817, we get 305.
Grab the next digit (0) from the dividend, add it to 305, then carry on: 3050 / 439

Let's proceed to step 7:
When dividing 3050 by 439, we get 6 with a remainder of 416.
Use 6 as the next digit of our solution. 
Result so far: 20486.0
If we subtract 2634 from 3050, we get 416.
Append the next digit (0) from the dividend to 416 and continue with: 4160 / 439

Advancing to step 8:
439 can be fit into 4160 9 times, resulting in a remainder of 209.
The number 9 becomes the next digit in our result. 
Result so far: 204869.0
Subtracting 3951 from 4160 leaves us with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Going ahead to step 9:
2090 divided by 439 is 4 with a remainder of 334.
The next digit of our result is 4. 
Result so far: 204869.4
Deduct 1756 from 2090 and we're left with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Step 10:
439 can be fit into 3340 7 times, resulting in a remainder of 267.
The next digit of our result is 7. 
Result so far: 204869.47
The remainder is 267 after subtracting 3073 from 3340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

On to step 11:
When dividing 2670 by 439, we get 6 with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 204869.476
Subtract 2634 from 2670 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 12:
439 goes into 360 0 times with a remainder of 360.
The next digit of our result is 0. 
Result so far: 204869.476
If we subtract 0 from 360, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 13:
439 goes into 3600 8 times with a remainder of 88.
Use 8 as the next digit of our solution. 
Result so far: 204869.47608
If we subtract 3512 from 3600, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 14:
If we divide 880 by 439, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 204869.476082
Subtract 878 from 880 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 15:
If we divide 20 by 439, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 204869.476082
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 16:
439 goes into 200 0 times with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 204869.476082
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

In conclusion, the division gives 204869.476082 with a balance of 2e-07.
