We look at the division of 85375385 by 899 
The aim is to understand the frequency of 899 in 85375385.

Advancing to step 1:
If we divide 8 by 899, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 899

On to step 2:
If we divide 85 by 899, we get 0 and a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Fetch the next digit (3) from the dividend, attach it to 85 and continue: 853 / 899

Moving on to step 3:
853 divided by 899 is 0 with a remainder of 853.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 853, we get 853.
Append the next digit (7) from the dividend to 853 and continue with: 8537 / 899

Moving on to step 4:
899 can be fit into 8537 9 times, resulting in a remainder of 446.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 8091 from 8537, we get 446.
Include the next digit (5) from the dividend after 446, then repeat: 4465 / 899

Step 5:
899 goes into 4465 4 times with a remainder of 869.
The next digit of our result is 4. 
Result so far: 94.0
The remainder is 869 after subtracting 3596 from 4465.
Fetch the next digit (3) from the dividend, attach it to 869 and continue: 8693 / 899

Let's proceed to step 6:
When dividing 8693 by 899, we get 9 with a remainder of 602.
Put 9 as the next digit of the answer. 
Result so far: 949.0
The remainder is 602 after subtracting 8091 from 8693.
Fetch the next digit (8) from the dividend, attach it to 602 and continue: 6028 / 899

Advancing to step 7:
When dividing 6028 by 899, we get 6 with a remainder of 634.
Use 6 as the next digit of our solution. 
Result so far: 9496.0
Subtracting 5394 from 6028 leaves us with 634.
Fetch the next digit (5) from the dividend, attach it to 634 and continue: 6345 / 899

Going ahead to step 8:
The number 899 fits into 6345 7 times, leaving a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 94967.0
The remainder is 52 after subtracting 6293 from 6345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 9:
When dividing 520 by 899, we get 0 with a remainder of 520.
Put 0 as the next digit of the answer. 
Result so far: 94967.0
If we take 0 away from 520, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 10:
When dividing 5200 by 899, we get 5 with a remainder of 705.
Record the quotient 5 as the next digit in the result. 
Result so far: 94967.05
The remainder is 705 after subtracting 4495 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

Moving on to step 11:
If we divide 7050 by 899, we get 7 and a remainder of 757.
Write down 7 as next digit of the result. 
Result so far: 94967.057
Deduct 6293 from 7050 and we're left with 757.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7570, and continue the process.

Let's proceed to step 12:
7570 divided by 899 is 8 with a remainder of 378.
Put 8 as the next digit of the answer. 
Result so far: 94967.0578
If we subtract 7192 from 7570, we get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Step 13:
899 goes into 3780 4 times with a remainder of 184.
Put 4 as the next digit of the answer. 
Result so far: 94967.05784
The remainder is 184 after subtracting 3596 from 3780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 14:
1840 divided by 899 is 2 with a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 94967.057842
Subtracting 1798 from 1840 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 15:
If we divide 420 by 899, we get 0 and a remainder of 420.
Use 0 as the next digit of our solution. 
Result so far: 94967.057842
If we subtract 0 from 420, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 16:
If we divide 4200 by 899, we get 4 and a remainder of 604.
Record the quotient 4 as the next digit in the result. 
Result so far: 94967.05784204
Subtract 3596 from 4200 to get 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Our division results in 94967.05784204 with a remaining 6.04e-07.
