We look at the division of 59690433 by 899 
The aim is to understand the frequency of 899 in 59690433.

On to step 1:
If we divide 5 by 899, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 899

On to step 2:
899 can be fit into 59 0 times, resulting in a remainder of 59.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 59 after subtracting 0 from 59.
Bring next digit (6) of the dividend behind the 59 and repeat the process: 596 / 899

On to step 3:
If we divide 596 by 899, we get 0 and a remainder of 596.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 596 after subtracting 0 from 596.
Include the next digit (9) from the dividend after 596, then repeat: 5969 / 899

On to step 4:
If we divide 5969 by 899, we get 6 and a remainder of 575.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 5394 from 5969 and we're left with 575.
Take the next digit (0) from the dividend and append it to 575, then repeat: 5750 / 899

Going ahead to step 5:
If we divide 5750 by 899, we get 6 and a remainder of 356.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
The remainder is 356 after subtracting 5394 from 5750.
Bring next digit (4) of the dividend behind the 356 and repeat the process: 3564 / 899

Going ahead to step 6:
899 can be fit into 3564 3 times, resulting in a remainder of 867.
The number 3 becomes the next digit in our result. 
Result so far: 663.0
Subtract 2697 from 3564 to get 867.
Bring next digit (3) of the dividend behind the 867 and repeat the process: 8673 / 899

Step 7:
899 goes into 8673 9 times with a remainder of 582.
The next digit of our result is 9. 
Result so far: 6639.0
The remainder is 582 after subtracting 8091 from 8673.
Grab the next digit (3) from the dividend, add it to 582, then carry on: 5823 / 899

Moving on to step 8:
899 goes into 5823 6 times with a remainder of 429.
Write down 6 as next digit of the result. 
Result so far: 66396.0
The remainder is 429 after subtracting 5394 from 5823.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Moving on to step 9:
If we divide 4290 by 899, we get 4 and a remainder of 694.
Record the quotient 4 as the next digit in the result. 
Result so far: 66396.4
Subtracting 3596 from 4290 leaves us with 694.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

Advancing to step 10:
899 goes into 6940 7 times with a remainder of 647.
Use 7 as the next digit of our solution. 
Result so far: 66396.47
Subtracting 6293 from 6940 leaves us with 647.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6470, and continue the process.

Let's proceed to step 11:
6470 divided by 899 is 7 with a remainder of 177.
Record the quotient 7 as the next digit in the result. 
Result so far: 66396.477
Deduct 6293 from 6470 and we're left with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

The final outcome is 66396.477, with a leftover of 0.0177.
