Let's divide 2258576 by 850
The aim is to understand the frequency of 850 in 2258576.

Going ahead to step 1:
850 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 850

On to step 2:
If we divide 22 by 850, we get 0 and a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 22 leaves us with 22.
Append the next digit (5) from the dividend to 22 and continue with: 225 / 850

Going ahead to step 3:
The number 850 fits into 225 0 times, leaving a remainder of 225.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 225 leaves us with 225.
Grab the next digit (8) from the dividend, add it to 225, then carry on: 2258 / 850

Advancing to step 4:
850 can be fit into 2258 2 times, resulting in a remainder of 558.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 1700 from 2258 to get 558.
Bring next digit (5) of the dividend behind the 558 and repeat the process: 5585 / 850

Let's proceed to step 5:
850 can be fit into 5585 6 times, resulting in a remainder of 485.
Use 6 as the next digit of our solution. 
Result so far: 26.0
Subtract 5100 from 5585 to get 485.
Grab the next digit (7) from the dividend, add it to 485, then carry on: 4857 / 850

On to step 6:
When dividing 4857 by 850, we get 5 with a remainder of 607.
Record the quotient 5 as the next digit in the result. 
Result so far: 265.0
The remainder is 607 after subtracting 4250 from 4857.
Include the next digit (6) from the dividend after 607, then repeat: 6076 / 850

Let's proceed to step 7:
850 goes into 6076 7 times with a remainder of 126.
The next digit of our result is 7. 
Result so far: 2657.0
The remainder is 126 after subtracting 5950 from 6076.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 8:
850 goes into 1260 1 times with a remainder of 410.
The number 1 becomes the next digit in our result. 
Result so far: 2657.1
The remainder is 410 after subtracting 850 from 1260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Let's proceed to step 9:
The number 850 fits into 4100 4 times, leaving a remainder of 700.
Put 4 as the next digit of the answer. 
Result so far: 2657.14
The remainder is 700 after subtracting 3400 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Step 10:
7000 divided by 850 is 8 with a remainder of 200.
The next digit of our result is 8. 
Result so far: 2657.148
Deduct 6800 from 7000 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 11:
850 can be fit into 2000 2 times, resulting in a remainder of 300.
The next digit of our result is 2. 
Result so far: 2657.1482
If we take 1700 away from 2000, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 12:
When dividing 3000 by 850, we get 3 with a remainder of 450.
Write down 3 as next digit of the result. 
Result so far: 2657.14823
The remainder is 450 after subtracting 2550 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 13:
When dividing 4500 by 850, we get 5 with a remainder of 250.
The number 5 becomes the next digit in our result. 
Result so far: 2657.148235
The remainder is 250 after subtracting 4250 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 14:
2500 divided by 850 is 2 with a remainder of 800.
Write down 2 as next digit of the result. 
Result so far: 2657.1482352
Subtract 1700 from 2500 to get 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Going ahead to step 15:
850 goes into 8000 9 times with a remainder of 350.
The number 9 becomes the next digit in our result. 
Result so far: 2657.14823529
If we take 7650 away from 8000, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

The final outcome is 2657.14823529, with a leftover of 3.5e-07.
