We look at the division of 25119074 by 899 
The aim is to understand the frequency of 899 in 25119074.

Step 1:
If we divide 2 by 899, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 899

Step 2:
899 can be fit into 25 0 times, resulting in a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 899

Advancing to step 3:
The number 899 fits into 251 0 times, leaving a remainder of 251.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 251, we get 251.
Grab the next digit (1) from the dividend, add it to 251, then carry on: 2511 / 899

Step 4:
When dividing 2511 by 899, we get 2 with a remainder of 713.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 1798 away from 2511, we end up with 713.
Take the next digit (9) from the dividend and append it to 713, then repeat: 7139 / 899

Advancing to step 5:
7139 divided by 899 is 7 with a remainder of 846.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Deduct 6293 from 7139 and we're left with 846.
Take the next digit (0) from the dividend and append it to 846, then repeat: 8460 / 899

Going ahead to step 6:
899 goes into 8460 9 times with a remainder of 369.
Put 9 as the next digit of the answer. 
Result so far: 279.0
Deduct 8091 from 8460 and we're left with 369.
Append the next digit (7) from the dividend to 369 and continue with: 3697 / 899

Advancing to step 7:
899 goes into 3697 4 times with a remainder of 101.
Write down 4 as next digit of the result. 
Result so far: 2794.0
Subtract 3596 from 3697 to get 101.
Grab the next digit (4) from the dividend, add it to 101, then carry on: 1014 / 899

Advancing to step 8:
When dividing 1014 by 899, we get 1 with a remainder of 115.
Use 1 as the next digit of our solution. 
Result so far: 27941.0
Deduct 899 from 1014 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Let's proceed to step 9:
899 goes into 1150 1 times with a remainder of 251.
Write down 1 as next digit of the result. 
Result so far: 27941.1
If we subtract 899 from 1150, we get 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

On to step 10:
899 goes into 2510 2 times with a remainder of 712.
Record the quotient 2 as the next digit in the result. 
Result so far: 27941.12
If we take 1798 away from 2510, we end up with 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Moving on to step 11:
When dividing 7120 by 899, we get 7 with a remainder of 827.
Record the quotient 7 as the next digit in the result. 
Result so far: 27941.127
If we subtract 6293 from 7120, we get 827.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8270, and continue the process.

Let's proceed to step 12:
8270 divided by 899 is 9 with a remainder of 179.
Use 9 as the next digit of our solution. 
Result so far: 27941.1279
If we take 8091 away from 8270, we end up with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Advancing to step 13:
899 can be fit into 1790 1 times, resulting in a remainder of 891.
Write down 1 as next digit of the result. 
Result so far: 27941.12791
Subtract 899 from 1790 to get 891.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8910, and continue the process.

Going ahead to step 14:
If we divide 8910 by 899, we get 9 and a remainder of 819.
Put 9 as the next digit of the answer. 
Result so far: 27941.127919
Deduct 8091 from 8910 and we're left with 819.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8190, and continue the process.

Going ahead to step 15:
If we divide 8190 by 899, we get 9 and a remainder of 99.
Use 9 as the next digit of our solution. 
Result so far: 27941.1279199
Deduct 8091 from 8190 and we're left with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

The final outcome is 27941.1279199, with a leftover of 9.9e-07.
