We're dividing 40579016 by 899 
The aim is to understand the frequency of 899 in 40579016.

Let's proceed to step 1:
When dividing 4 by 899, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 899

On to step 2:
If we divide 40 by 899, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 899

Going ahead to step 3:
If we divide 405 by 899, we get 0 and a remainder of 405.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 405 to get 405.
Take the next digit (7) from the dividend and append it to 405, then repeat: 4057 / 899

Step 4:
If we divide 4057 by 899, we get 4 and a remainder of 461.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 3596 away from 4057, we end up with 461.
Fetch the next digit (9) from the dividend, attach it to 461 and continue: 4619 / 899

Step 5:
899 can be fit into 4619 5 times, resulting in a remainder of 124.
Write down 5 as next digit of the result. 
Result so far: 45.0
Deduct 4495 from 4619 and we're left with 124.
Append the next digit (0) from the dividend to 124 and continue with: 1240 / 899

Moving on to step 6:
1240 divided by 899 is 1 with a remainder of 341.
The next digit of our result is 1. 
Result so far: 451.0
If we subtract 899 from 1240, we get 341.
Fetch the next digit (1) from the dividend, attach it to 341 and continue: 3411 / 899

Advancing to step 7:
If we divide 3411 by 899, we get 3 and a remainder of 714.
Record the quotient 3 as the next digit in the result. 
Result so far: 4513.0
The remainder is 714 after subtracting 2697 from 3411.
Grab the next digit (6) from the dividend, add it to 714, then carry on: 7146 / 899

Step 8:
The number 899 fits into 7146 7 times, leaving a remainder of 853.
Use 7 as the next digit of our solution. 
Result so far: 45137.0
Subtract 6293 from 7146 to get 853.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8530, and continue the process.

Advancing to step 9:
When dividing 8530 by 899, we get 9 with a remainder of 439.
Put 9 as the next digit of the answer. 
Result so far: 45137.9
The remainder is 439 after subtracting 8091 from 8530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Advancing to step 10:
If we divide 4390 by 899, we get 4 and a remainder of 794.
Use 4 as the next digit of our solution. 
Result so far: 45137.94
The remainder is 794 after subtracting 3596 from 4390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

Let's proceed to step 11:
When dividing 7940 by 899, we get 8 with a remainder of 748.
Write down 8 as next digit of the result. 
Result so far: 45137.948
Subtracting 7192 from 7940 leaves us with 748.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7480, and continue the process.

On to step 12:
899 can be fit into 7480 8 times, resulting in a remainder of 288.
The number 8 becomes the next digit in our result. 
Result so far: 45137.9488
Subtracting 7192 from 7480 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The final outcome is 45137.9488, with a leftover of 0.00288.
