We look at the division of 89969455 by 839 
The aim is to understand the frequency of 839 in 89969455.

Going ahead to step 1:
8 divided by 839 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 839

On to step 2:
839 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.
Append the next digit (9) from the dividend to 89 and continue with: 899 / 839

On to step 3:
When dividing 899 by 839, we get 1 with a remainder of 60.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 839 from 899 and we're left with 60.
Grab the next digit (6) from the dividend, add it to 60, then carry on: 606 / 839

Moving on to step 4:
The number 839 fits into 606 0 times, leaving a remainder of 606.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 606 to get 606.
Bring next digit (9) of the dividend behind the 606 and repeat the process: 6069 / 839

Moving on to step 5:
839 goes into 6069 7 times with a remainder of 196.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
Deduct 5873 from 6069 and we're left with 196.
Bring next digit (4) of the dividend behind the 196 and repeat the process: 1964 / 839

Step 6:
839 can be fit into 1964 2 times, resulting in a remainder of 286.
Write down 2 as next digit of the result. 
Result so far: 1072.0
Deduct 1678 from 1964 and we're left with 286.
Take the next digit (5) from the dividend and append it to 286, then repeat: 2865 / 839

Moving on to step 7:
If we divide 2865 by 839, we get 3 and a remainder of 348.
The next digit of our result is 3. 
Result so far: 10723.0
The remainder is 348 after subtracting 2517 from 2865.
Take the next digit (5) from the dividend and append it to 348, then repeat: 3485 / 839

Going ahead to step 8:
839 can be fit into 3485 4 times, resulting in a remainder of 129.
Write down 4 as next digit of the result. 
Result so far: 107234.0
Deduct 3356 from 3485 and we're left with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Moving on to step 9:
839 can be fit into 1290 1 times, resulting in a remainder of 451.
Record the quotient 1 as the next digit in the result. 
Result so far: 107234.1
If we take 839 away from 1290, we end up with 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Step 10:
When dividing 4510 by 839, we get 5 with a remainder of 315.
Put 5 as the next digit of the answer. 
Result so far: 107234.15
If we subtract 4195 from 4510, we get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Step 11:
When dividing 3150 by 839, we get 3 with a remainder of 633.
Put 3 as the next digit of the answer. 
Result so far: 107234.153
If we subtract 2517 from 3150, we get 633.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6330, and continue the process.

Let's proceed to step 12:
If we divide 6330 by 839, we get 7 and a remainder of 457.
The number 7 becomes the next digit in our result. 
Result so far: 107234.1537
Subtract 5873 from 6330 to get 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Moving on to step 13:
4570 divided by 839 is 5 with a remainder of 375.
Put 5 as the next digit of the answer. 
Result so far: 107234.15375
Subtracting 4195 from 4570 leaves us with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Advancing to step 14:
The number 839 fits into 3750 4 times, leaving a remainder of 394.
Record the quotient 4 as the next digit in the result. 
Result so far: 107234.153754
The remainder is 394 after subtracting 3356 from 3750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Going ahead to step 15:
When dividing 3940 by 839, we get 4 with a remainder of 584.
Put 4 as the next digit of the answer. 
Result so far: 107234.1537544
Subtracting 3356 from 3940 leaves us with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

In conclusion, the division gives 107234.1537544 with a balance of 5.84e-06.
